09:07:37 [bwm]
Ralph: welcome all
09:07:59 [bwm]
... one of oour deliverables is to bring in other communities
09:08:39 [sdehors]

... this session is best practices process and practice
09:08:54 [bwm]
... procedural matters that affect the way we operate
09:08:58 [dajobe_]
ralphS shows
09:09:35 [bwm]
... recommednation track work has different procedures from other forms of publication
09:09:59 [bwm]
... talk about social practices, e.g. tools, expectations of colleauges in w3c
09:10:20 [bwm]
... making work accessible to others
09:10:36 [bwm]
... talk about expectations of other groups as well
09:10:51 [bwm]
w3c formal process is in the process document
09:11:11 [JosD_]
pointer to Ralph's talk
09:11:24 [bwm]
09:11:30 [DanC_jam]
the process document has a pretty new 1-page summary that I heartily endorse:
09:11:47 [bwm]
... important to understand impact of intellectual property process
09:11:55 [bwm]
... we are royalty free
09:12:54 [bwm]
... from a formal point of view, if we choose to create a recommendation, then we need to make sure that we document all the ipr that anyone may have that relates to that
09:13:53 [bwm]
... groundwork for doing a recommendation requires that ac reps approve royalty free process
09:14:57 [bwm]
... this group is authorised to do rec track work
09:15:25 [bwm]
... the new patent policy is new - less than a month old - we are beta testers
09:15:35 [danbri]
danbri has joined #swbp
09:16:33 [bwm]
as part of signing up for wg, ac rep must agree to royalty free process
09:17:07 [bwm]
???: will bulk of our deliverables be as notes
09:17:15 [bwm]
Ralph: my bias is yes
09:17:28 [bwm]
... Notes don't have an explicity ipr process around them
09:17:34 [bwm]
... they do have copyright
09:18:22 [bwm]
... our objective is to increase consensus in the use of these tools
09:18:55 [bwm]
... we will develop consensus amongst ourselves and in the wider community
09:19:21 [bwm]
... Where are we now
09:19:31 [bwm]
... Ralph shows diagram of w3c process
09:20:00 [bwm]
... starts with a need from the community
09:20:16 [bwm]
... arrived at through informal discussions, possibly workshops ...
09:20:33 [Guus]
Guus has joined #swbp
09:20:39 [bwm]
... ideas incorporated in an activty proposal reviewed by members of w3c
09:20:56 [bwm]
... the WG gets a formal charter
09:21:24 [bwm]
.. takes 2-4 months to charter an activity/working group
09:21:49 [bwm]
... we have pushed the schedule, doing much in parallel so we could meet today
09:22:02 [DanC_jam]
(2-4 months is pretty low, I'd say)
09:22:03 [bwm]
... the formal call for participation has only gone out a week ago
09:22:10 [bwm]
... expect more participants
09:22:33 [bwm]
... most w3c wgs are expected to produce working drafts as part of the rec track process
09:22:41 [bwm]
... this group may produce more notes
09:22:48 [bwm]
... which isnot a new process
09:23:04 [bwm]
... there is precedent for how this group operates
09:23:18 [bwm]
... if we choose to publish a recommendation, then we publish several wd's
09:23:33 [danbri]
(re WAI, see
09:23:57 [bwm]
... objective is to build consensus
09:24:27 [bwm]
... there are some practices from which we will select, add etc
09:24:37 [bwm]
... we first form consensus amongst ourselves
09:24:46 [bwm]
... we ask people to participate in our task forces
09:24:58 [bwm]
... work out the best consensus we can arrange locally and then expand outward
09:25:29 [bwm]
... ralph recommends The Art of Concensus

(the doc is A Guidebook for W3C Working Group Chairs and other Collaborators)
09:26:25 [bwm]
... we are expected to keep relatively detailed minutes of meetings and telecon
09:26:31 [bwm]
... it is vital to document decisions
09:26:50 [bwm]
... important to document options and useful to document rationale
09:27:01 [bwm]
... helps to build consensus if folsk understand the reasons
09:27:20 [DanC_jam]
09:27:37 [bwm]
... moving on for shortage of time
09:27:51 [bwm]
... part of what we will discuss is how we expect to achieve our deliverables
09:28:14 [bwm]
... expectations of task forces
09:28:22 [bwm]
... probably will have telecons
09:28:30 [bwm]
... we can choose whether to use irc
09:28:44 [bwm]
... there are tools help make irc more effective
09:28:53 [bwm]
... no time to introduce those
09:29:11 [bwm]
... decided that deliberations of the wg are open to the public
09:29:34 [bwm]
... 'd' dropped from the mailing list name
09:29:48 [bwm]
... the mailing list archive is open to public to read
09:30:27 [bwm]
... until yesterday only folks who had signed up to the wg could post to the list but it is now open
09:30:39 [bwm]
... will a wiki help us
09:30:54 [bwm]
... w3c infrastructure does not formally support wiki's yet
09:31:02 [bwm]
... but we have expereince in swad-e
09:31:13 [bwm]
... we can consider whether to use one
09:31:26 [bwm]
... we do produce formal published documents
09:31:41 [bwm]
... such documents must have a certain style, should validate etc
09:31:51 [bwm]
... there is a set of publication guidelines
09:32:04 [bwm]
... there is a set of best practices for all w3c pages
09:32:21 [bwm]
... we ahve assistance from the communictions team e.g. marie-claire
09:32:30 [bwm]
... they are very hard worked
09:33:23 [bwm]
... new opportunity - we were approached by society for technical communication who offered writers so we might get some help to write the documents
09:33:41 [bwm]
... we may be a suitable group to take advantage of that opportunity
09:34:36 [bwm]
guus: we will come back to issues around planning, telecons, f2f etc
09:34:44 [bwm]
... expect to have f2f twice a year
09:34:53 [DanC_jam]
fyi, many of the materials mentioned in Ralph's talk are on the WG homepage too.
09:34:55 [bwm]
... get requirments of people on the table
09:35:19 [bwm]
.. this pm we will discuss notion of task force

10:14:42 [db-scribe]
thinking of priorities for semweb ontologies
10:14:46 [db-scribe]
for final users
10:14:50 [db-scribe]
1) Learn logic
10:14:52 [DanC_jam]
Thu, 04 Mar 2004 10:14:46 GMT
10:14:56 [db-scribe]
2) Learn formal logic
10:15:04 [db-scribe]
3) Learn knowledge acquisiton
10:15:23 [db-scribe]
given these three reqs
10:15:45 [db-scribe]
the chance of success is None if thet target is semantic web users
10:16:17 [db-scribe]
chance is Reasonable, if the expectations turn into requirements for ontology construction tools
10:16:35 [db-scribe]
chance = 1 (certainty), if ?? unknown
10:16:39 [db-scribe]
Priotities for best practices
10:16:49 [db-scribe]
* logic construction patterns (canonical forms)
10:16:58 [db-scribe]
- tempaltes, examples, familar interfaces
10:17:14 [db-scribe]
* Ontology design patterns (content skeeltons)
10:17:45 [db-scribe]
- templates at the content level, step-by-step maieutics and examples
10:17:46 [DanC_jam]
10:17:55 [db-scribe]

Ardo shows an ontology requirements diagram
10:20:28 [fabien_gandon_]
Maieutics, n. The art of giving birth (i. e., clearness and conviction) to ideas, which are conceived as struggling for birth.

Bernard Vatant
10:21:46 [db-scribe]
BV - people like to make their own stuff, ontologies
10:22:00 [db-scribe]
.. we should make/define reusable ontologies
10:22:05 [timbl]
[A slide mailed to *before* the talk is of course on the web]
10:22:37 [db-scribe]
a too generic tech is not so useful
10:22:43 [db-scribe]
FOAF's pretty useful
10:22:53 [db-scribe]
we should focus on that kind of scope, ground level and sharable
10:22:57 [db-scribe]
2nd point -
10:23:18 [db-scribe]
how do i work with my legacy stuff
10:23:21 [db-scribe]
3rd point -
10:23:39 [db-scribe]
tension between private and shared knowledge
10:24:46 [db-scribe]
customers say tm and ontologies may be cool, but for my intranet stuff, don't care

FT semweb context
10:26:03 [db-scribe]
lots of different business needs
10:26:09 [db-scribe]
what are the semweb links
10:26:36 [db-scribe]
trying to illustrate with concrete use cases and convincing demos
10:26:51 [db-scribe]
for this group and our workw ith knowledgeweb need a showcase that shows the value
10:27:07 [db-scribe]
don't want to know the logic, ontology detail, just the benefits
10:27:35 [db-scribe]
showing the value as quick as possible
10:27:40 [db-scribe]
one way, generating use cases
10:27:51 [db-scribe]
guidelines and best practices
10:27:59 [db-scribe]
and supporting education outside our group
10:28:10 [db-scribe]
top 3 priorities
10:28:16 [db-scribe]
1) repository of tools and demo apps
10:28:24 [db-scribe]
- well organsied for industry to find ou thie best choice of tools
10:28:40 [db-scribe]
- realistic demos, not toy demos
10:28:59 [db-scribe]
there are lots of toy ones
10:29:06 [db-scribe]
- show it works in a realistic context
10:29:11 [db-scribe]
2) interopability
10:29:22 [db-scribe]
- we have lots of needs as a telcom operator
10:29:29 [DanC_jam]
10:29:32 [db-scribe]
- support Bernard - private & public parts
10:29:40 [aldoG]
aldoG has joined #swbp
10:30:08 [db-scribe]
- ontology mappings, MPEG using with w3c environment, many other examples
10:30:15 [db-scribe]
3) Guidelines
10:30:37 [db-scribe]
- for making it plug and play
10:30:44 [db-scribe]
- difficucult to get industrial-grade best practices
10:30:54 [db-scribe]
maybe some prefer to keep them private?
10:30:58 [db-scribe]
- success stories
10:31:04 [db-scribe]
we know some in this area
10:31:10 [db-scribe]
Marco, FT continues
10:31:16 [db-scribe]
FT=France Telecom also
10:31:52 [db-scribe]
semantic application compared to semantic web application
10:32:05 [db-scribe]
can I use semweb techniques, word web too limited
10:32:11 [db-scribe]
inside my organisation
10:32:54 [db-scribe]
where do I apply these teqniques, between services? at the edge, or re-engineer a lot of systems
10:33:23 [db-scribe]
afraid that semweb techniniques can only be viewed as exchanging data between two partners, and not of use internally
10:33:53 [db-scribe]
for e.g. when is an OO app is better/worse than a semweb app? no simple response
10:34:04 [db-scribe]
Dirk, Asemantics replies
10:34:30 [db-scribe]
- more of a presentation problem maybe, or is there something missing?
10:34:40 [db-scribe]
- like can they use xml and not do graphs?
10:34:49 [db-scribe]
Marco, FT:
10:35:33 [db-scribe]
- have to be convinced we can 1) build big, critical programs with these techniques
10:35:42 [db-scribe]
Mike, Boeing -
10:35:53 [db-scribe]
2nd semantic & semanticweb
10:36:08 [db-scribe]
there may not be any link anywhere with some semantic web app - on the web or off
10:36:16 [timbl]
The chief benefit of semantic web is reuse. Resuse of data -- use across applications -- only pays off when you have several applicstions involved. resue of design -- the fact that ontolgy work is about real things rather than programming artifacts -- pays off as you design and especially when you redesign an application.
10:36:23 [db-scribe]
Dirk, Asemantics -
10:36:41 [db-scribe]
- semweb tech you see triples at the core, but in the apps you find other things like provenance
10:36:55 [db-scribe]
- so if you are on best practice side, you may be adding extra elements
10:37:32 [db-scribe]
- maybe one of the outreach things could be documentating where you practically have to go off the path, in order to build industrial-strength semweb apps
10:38:04 [db-scribe]
Libby Milller, University of Bristol:
10:38:41 [db-scribe]
1) examples and tests where appropraite
10:38:44 [db-scribe]
can be very useful
10:38:52 [db-scribe]
2) identification of things
10:38:58 [db-scribe]
in particular people, events
10:39:11 [db-scribe]
people like to assign uris for people, we've been using the owl:inverseFunctionalProperty
10:39:17 [db-scribe]
ways to write this down would be useful
10:39:23 [db-scribe]
3) for newbies, pointers to existing vocabs
10:39:31 [db-scribe]
how to find them, mechanisms for reusing them and mixing themj
10:39:54 [db-scribe]
Guus - how suitable is FOAF as a semweb demo app? for convincing outsiders?
10:40:06 [db-scribe]
LM - seems to convince people qutie well, open
10:40:21 [DanC_jam]
on foaf as a demo: it has nice eye-candy SVG tools. but it gets hash-vs-slash wrong.
10:40:38 [db-scribe]
LM - people do get it as a compelling app, also 'cos it is about people
10:40:40 [timbl]
[it uses no hash in its namespace which is an architectural problem and a bad example]
10:40:57 [db-scribe]
danbri - have been trying to explain rdf for years, find it easier for foaf
10:41:05 [db-scribe]
LM - about things in the world rather than on the web
10:41:08 [shawn]
shawn has joined #swbp
10:41:19 [db-scribe]

10:41:50 [db-scribe]
jjc=Jeremy Carroll, HP
10:42:07 [db-scribe]
Ivan Herman -
10:42:20 [db-scribe]
foaf is fun yeah, but what are the big business oriented apps?
10:42:26 [db-scribe]
this is not one
10:42:46 [db-scribe]
one I usually refer to is Baby Care (ref to AC meeting in Yokohama)
10:43:06 [db-scribe]
Guus asks Ivan to talk about this later
10:43:16 [timbl]
[I note that there are already several FOAF-oriented commercial sites, one of which exprts FOAF]
10:43:20 [db-scribe]
Liddy neville -
10:43:31 [db-scribe]
separate the general from the specific; foaf is a general class of things
10:43:39 [timbl]
Zakim, mute me
10:43:39 [Zakim]
TimBL should now be muted
10:43:53 [db-scribe]

10:45:34 [db-scribe]
^- background items
10:45:37 [db-scribe]
10:45:42 [db-scribe]
1) make an rdf/owl portal

^- is 1)
10:48:36 [db-scribe]
2) development of, registration of vocabs to make people's learning curve easier
10:49:03 [db-scribe]
3) answer why you want to express it in rdf?, isn't xml good enough?
10:49:15 [db-scribe]
- been asked by 4 groups available, mostly at the database end
10:49:33 [db-scribe]
- the scope of the group needs to expand a little
10:49:56 [gk]
Why isn't XML good enough? After long discussion last night, I think the answer may be "RDF solves the mixed namespace problem" (cf. yesterday's plenary discussion)
10:50:06 [db-scribe]
Chuck outlines detailed workflow and semweb may apply
10:50:15 [db-scribe]
good to have some of those people participating in the WG
10:50:19 [DanC_jam]
(it solves an interesting part of the namespace mixing problem, anyway)
10:50:22 [bijan]
gk, :)
10:50:45 [db-scribe]
Dan Brickley, W3C/ILRT:
10:50:49 [bijan]
I guess I don't have a crisp understanding of the mixed namespace problem
10:50:54 [DanC_jam]
Guus: I intend to follow up with you, Chuck Meyers
10:51:04 [db-scribe]
main rdf specs finished

RDF doesn't *have* a mixing namespace problem...but it doesn't have namespaces
10:51:18 [db-scribe]
lots of stuff for BPD potentially
10:51:31 [db-scribe]
lets focus on gatherhing storeis not just use cases
10:51:44 [db-scribe]
talk to earliy adopters, kr old terms and newcomers
10:51:57 [db-scribe]
such as if newcomers read stuff and felt stupid, find out what was going non
10:52:00 [db-scribe]
10:52:04 [db-scribe]
10:52:04 [timbl]
Gk: When, really thhe answer is that SemWeb is a more pwerful technology in many ways. But the fact that is has solved the ns mixing problem is a big thing -- in tha XML technologies which don't discuss what thinsg mean are incapable fo solving that problem generically.
10:52:09 [db-scribe]
1) thesauri on the sw using rdf/owl
10:52:24 [db-scribe]
2) what you put at a namsespace uri - techniques for useful info behind them - rdf/owl/xjhtml
10:52:28 [gk]
bijan, sure that's another way of expressing it. But, from yesterday's discussion, XML *does* have some issues with composing documents using different namespaces.
10:52:30 [db-scribe]
3) [too slow]

10:53:33 [dlm]
if there is a url for slides though, that is good to paste in this log
10:53:42 [db-scribe]
there is no url, that's the point
10:53:48 [bijan]
gk, it's not an other way of expressing it :) It's expressing something different!
10:54:12 [db-scribe]
danbri explains thes stuff
10:54:25 [timbl]
And that is why it has solved the namespaec mixing problem.
10:54:30 [db-scribe]
danbri 2) vocab documentation
10:54:37 [db-scribe]
.. seems like a job for the TAG
10:54:54 [db-scribe]
the rest is on the mythical slides
10:55:20 [db-scribe]
go out see what people have done
10:55:25 [db-scribe]
3) versioning
10:55:35 [db-scribe]
vocab versioning
10:55:50 [bijan]
Look, I think it's just an error to say you've solved a problem if you merely redefine it *without* demonstrating that your redefinition meets the needs of the people with the problem
10:56:02 [db-scribe]
costs of changing, would like to see thoughts on changing vocab and costs
10:56:18 [DanC_jam]
(hmm... can you measure the level of agreement between what a "namespace document" says and what the data files say about those terms? we do a little bit of that in RDF calendar)
10:56:21 [db-scribe]
Jos De Roo, AGFA-Gevaert
10:56:23 [timbl]
Bijan, you talking about the ns mixing problem?
10:56:23 [danbri]
OK how to rescue that from powerpoint? maybe I'll cut and paste...
10:56:26 [bijan]
Such moves tend to irritate the people with the problem. Rightly I think.
10:56:27 [JosD_]
10:56:30 [bijan]

2) test results
10:58:19 [bijan]
I mean, in some important sense, XML can solve the mixed namespace problem the same way RDF does: Don't use namespaces! Done! :)
10:58:26 [db-scribe]
an extension or an ontology for a more clafieid output
10:58:45 [db-scribe]
10:59:06 [db-scribe]
pracitcal use case
10:59:20 [db-scribe]
believe it should be hands on, bottom-up
10:59:35 [db-scribe]
semantic web is to some extent webizing real world problems
10:59:39 [db-scribe]
Guus -
10:59:57 [db-scribe]
interested in formal pub of medical vocabularies?
11:00:03 [bijan]
RDF, or OWL at least, *has* some vocabulary mixing problems, e.g., combining two owl lite documents can produce an owl full...Surprise!
11:00:22 [db-scribe]
discussion of public/pay for medical vocabs
11:00:24 [gk]
bijan, I think that needs more explanation, just as my terse assertion also does. I'm reluctant to continue this debate here, but happy to engage later.
11:00:24 [timbl]
[The namespace mixing problem: When you have two independently designed XML langauges each with define semantcis, how do you define the semantics of a document which uses a a mixture of the two langauges? RDF solution: constrain the XML langauges to be RDF. The semantics of the mixed langauge document is the set of triples defined by RDF]
11:00:39 [db-scribe]
Guus - could discuss later today
11:01:06 [bijan]
timbl, pifft. That's no solution. What are the semantics of a mixed namespace document in xml? The infoset
11:01:13 [db-scribe]
jjc - approaches could be mapping into owl
11:01:28 [db-scribe]
or the other way, is to describe methodologies to enable anyone to do it
11:01:31 [db-scribe]
11:01:37 [bijan]
RDF semantics doesnt' strongly constrain the meaning of RDF documents
11:02:00 [db-scribe]
11:02:19 [db-scribe]
jjc -
11:02:43 [db-scribe]
hp has put effort into jena, rdf core, webont ..
11:03:05 [db-scribe]
at present putting more effort into apps and Deployment, swbp'D'
11:03:17 [db-scribe]
looking for best practies to make better apps, deployment
11:03:40 [db-scribe]
as a W3C WG, it is important to link with other W3C activities, WGs
11:03:44 [db-scribe]
better links with the XML world
11:03:49 [danbri]
[doh, i forgot one of my hobbyhorses: find w3c-internal customers; but jjc saying something close]
11:04:14 [db-scribe]
talking to people who say XML is the answer
11:04:34 [db-scribe]
internationalization is very weak
11:04:39 [db-scribe]
... in semweb
11:04:48 [DanC_jam]
jjc: I18N of SemWeb technologies is somewhat weak.
11:04:51 [timbl]
11:05:01 [db-scribe]
Guus - language thesauri?
11:05:06 [db-scribe]
jjc - a small step
11:05:26 [db-scribe]
... more specifically rfc3306bis - next generation of xml:lang tag
11:05:42 [db-scribe]
... much clearer model of languages, dialects, scripts
11:05:54 [DanC_jam]
RFC 3066 - Tags for the Identification of Languages
11:06:18 [db-scribe]
Dirkx - there are also practical things you can do to work in an internationalized context, good to record them

Oscar Corcho <> (Universidad Polit?cnica de Madrid) --
11:10:06 [db-scribe]
motivated by best practices
11:10:25 [db-scribe]
some FAQs - how do I do this?
11:10:50 [db-scribe]
asked on various email lists
11:11:07 [DanC_jam]
"how can I do defaults" yes, that's a FAQ. an answer from W3C Semantic Web Advanced Development:
11:11:44 [db-scribe]
could provide some guidelines, improving the OWL guide
11:11:49 [db-scribe]
(These are all OWL questions)
11:11:50 [gk]
I think the OWL docs are v good, but I still don't feel that I know how to design an inference in OWL. So I think Oscar is spot on here.
11:12:00 [DanC_jam]
yeah verily.
11:13:01 [db-scribe]
some things are in the owl docs, some things not so clear and hard to find
11:13:12 [DanC_jam]
"can I use XML Schema derived datatypes?" another excellent example of a FAQ I'd like this WG to work on.
11:13:14 [db-scribe]
2) interoperability - frames vs description logics
11:13:38 [db-scribe]
transforming to/from frames / OWL/DL
11:14:08 [db-scribe]
several questions of what is good practice
11:15:13 [db-scribe]
interop between tools at EON2003, at ISWC semantic web conf found very bad
11:15:28 [gk]
This might be a good use for a SWBP WG wiki?
11:15:35 [db-scribe]
new workshop to find out at EON2004
11:15:36 [DanC_jam]
I hope so, gk
11:15:39 [db-scribe]
3) ontology repository
11:15:55 [db-scribe]
we've build a reference ontology in ontoweb work
11:16:03 [db-scribe]
for describing ontology tools and ontologies
11:16:14 [db-scribe]
apps, ontologies, lajnguages, methodologies
11:16:19 [fabien_gandon_]
URL of the repository :
11:16:38 [db-scribe]
Mike Uschold, Boeing
11:16:49 [db-scribe]
some from Jim Hendler
11:16:55 [db-scribe]
"semantics" term, loaded, semweb also
11:17:14 [db-scribe]
WG should come up with a statement, or point at several if there are >1
11:17:20 [gk]
Thinks, re wiki, just slightly off-topic: can we use sweb technologies to improve wiki indexing? I find wikis are good if you know what's there, but not always easy to discover topics.
11:17:24 [db-scribe]
2) where does meaning come from?
11:17:25 [danbri]
[fair point imho]
11:17:38 [danbri]
[fair point imho --- re documenting senses of 'semantics' we're buying into]

11:18:22 [db-scribe]

11:19:28 [db-scribe]
6) hybrid reasoning
11:19:36 [db-scribe]
reasoning in multiple modes
11:19:50 [db-scribe]
for e.g. DL can't do some things such as arithmetic
11:20:04 [ChrisWelty]
11:20:05 [db-scribe]
how to call out to other engines and still do ontological reasoning?
11:20:13 [db-scribe]
Chris Welty, IBM:
11:20:21 [DanC_jam]
hybrid reasoning is another thing we're researching. (we = W3C SemWeb AD, esp. MIT CSAIL)
11:21:02 [db-scribe]
db-scribe has changed the topic to:
11:21:09 [db-scribe]
1) jobs for BPWG
11:21:21 [DanC_jam]
11:21:49 [db-scribe]
not just any practice
11:21:55 [DanC_jam]
hmm... "we're not cheerleaders" -- I disagree.
11:22:15 [db-scribe]
our job is to solve common problems
11:22:30 [db-scribe]
tests not usually best practices
11:23:00 [db-scribe]
at least as in OWL, more like use cases
11:23:08 [db-scribe]
2) ontology patterns
11:23:18 [RalphS]
Chris: test cases are not necessarily the best documentation of the way to use the language
11:23:25 [db-scribe]
points to PartWhole wiki page
11:23:30 [db-scribe]
as an example pattern
11:23:40 [danbri]
[re hybrid reasoning, yes agree important tech topic -- esp when to reason about documents/provenence, then dip into the 'worldview of that document'; ie provenance/src in queries, apis etc]
11:24:01 [db-scribe]
3) documenting worst practices
11:24:04 [db-scribe]
i.e. modelling pitfalls
11:24:24 [db-scribe]
in particular the examples in the OWL guide
11:24:47 [timbl]
[I hope this group keeps close enough contact with users to have users, ontology deevlopers or prospective ones, come to the group to share experiences]
11:24:56 [DanC_jam]
(in wiki culture, worst practices are called AntiPatterns.

11:35:44 [db-scribe]
CC wants to enable striking a balance of rights on content with licenses to share
11:36:11 [db-scribe]
geared towards sharing, assuming that - talking about credit, non/commercial, derivative works etc.
11:36:27 [db-scribe]
just added a Sampling License
11:36:58 [db-scribe]
each license has 3 forms - human readbale deed, lawyer-readble legal code and machine-readable digital code
11:37:44 [db-scribe]
working hard translating it not just languages, but cross jurisdictional
11:38:27 [db-scribe]
the digital code, metadata is RDF
11:38:30 [RalphS]
BenA: cross-jurisdictional: e.g. what does "attribution" mean
11:38:47 [DanC_jam]
"what happens when you take a piece of content in license X and one in licnese Y an combine them?" -- Ben. I've done some N3 rules scribbling on that problem.
11:39:07 [db-scribe]
we tend to tell people to explain it to those who want to, others we just say put on their web page
11:39:16 [db-scribe]
BenA: shows the CC rdf license validato thing
11:39:46 [db-scribe]
11:40:25 [db-scribe]
the web form makes some html that you are meant to paste into your page

11:44:24 [db-scribe]
semblance of a conflict between
11:44:40 [db-scribe]
publishers control metadata (us), and others extract it (google etc.)
11:44:54 [db-scribe]
who don't believe you should be able to talk about your own page
11:45:23 [db-scribe]
Licensing metadata is only semantic web, nobody else can say about it.
11:45:36 [db-scribe]
the rest of world can't do it

we put rdf in comments now in html, no other way right now
11:47:45 [db-scribe]
uncomfortable with this, but it worked to get 1.2M pages
11:48:04 [db-scribe]
CC want simple howtos and clear recommendations
11:48:10 [danbri]
hmm, maybe i/we/... should revisit the 'does it make sense to use creative commons when publishing one's foaf, calendar data etc' question

Focus 1:
13:30:17 [RalphS]
13:30:23 [danbri_dna]
guus: use of 'ontology' in charter, could've said 'vocabulary'
13:30:27 [RalphS]
Focus 1: Supporting initiatives for publishing ontologies / vocabularies
13:30:33 [danbri_dna]
...lightweight ontos
13:30:47 [danbri_dna]
...what we put in the charter here, what i had in list as one of the early things we could work on...
13:31:03 [danbri_dna] early wg note on conversion of existing representations of thesauri into rdf/owl format
13:31:13 [danbri_dna]
...rdf/owl ie any combination of the two that fits the requirements best
13:31:18 [danbri_dna] rdfs, or extended to use owl
13:31:46 [danbri_dna]
...people wanting to port their stuff to this format... so they know what to do...
13:32:17 [danbri_dna]
...some things in this charter were invented by a small group of people, useful to discuss it in this group
13:32:35 [danbri_dna]
JosD: I believe it is fairly ambitious to convert large existing std vocabs
13:33:06 [danbri_dna]
...whereas i don't see a real alternative, i'm happy to support this, but it is very ambitious to claim a full conversion of say a ... vocab
13:33:15 [danbri_dna]
ChrisWelty: i don't think that's guus' goal
13:33:23 [danbri_dna]
ChrisWelty: focus on methods...
13:33:29 [danbri_dna]
guus: i've noticed ppl have already done this
13:33:40 [danbri_dna] wordnet, + work in swad-europe (on thesaurus metamodel)
13:33:45 [danbri_dna]
...for wordnet, several efforts
13:33:59 [danbri_dna]
...we in Amsterdam have done the AAT, Getty, ulan, iconclass
13:34:06 [danbri_dna]
...[something re iso stds]
13:34:12 [danbri_dna]
...have seen a few others, eg
13:34:16 [danbri_dna]
RalphS: FAO thes
13:34:25 [danbri_dna]
guus: fisheries
13:34:43 [libby] <- swad-e europe thesauri work
13:34:45 [danbri_dna]
em: /me comments aren't recorded; I suggest [foo bar] as out-of-band asides if you want on record
13:34:53 [RalphS]
13:34:59 [DanC_jam]
13:35:01 [danbri_dna]
[hmm the em:/ comment cryptic sorry]
13:35:04 [danbri_dna]
13:35:12 [danbri_dna]
guus: are there people here with particular views?
13:35:17 [danbri_dna]
RalphS: i see two approaches to this
13:35:25 [danbri_dna]
...look at specfic thesauri, eg wordnet
13:35:40 [danbri_dna]
...perhaps the way it is done now doesn't take advantage of all that could be done
13:35:48 [DanC_jam]
(I'm not clear whether this is about thesauri in particular or data representations in general, but I'll wait for volutneers who want to do this work, whatever it is, to let me know.)
13:36:02 [danbri_dna]
...or do it in terms of classes of thesaurus
13:36:09 [danbri_dna]
...which of those two?
13:36:18 [danbri_dna]
guus: the 1st issue we cannot do here just in the wg
13:36:22 [danbri_dna]
...better to collab with the vocab owner
13:36:33 [danbri_dna]
...maybe that is too strong a statement...
13:36:41 [DanC_jam]
(hmm... what's the shortest path from here to the WordNet developers?)
13:36:47 [danbri_dna]
...but i don't see the wg doing actual work on conversion unless in collaboration
13:37:18 [danbri_dna]
RalphS: that doesn't preclude us approaching them
13:37:28 [chaalsNCE]
[/me suggests that one of the valuable things is taking projects and writing them up a lot. Explaining at levels from "here's the schema, go for it" through "here's each piece as an example" to "here's how we decided to do the model, the alternatives and the implications..."]
13:37:33 [aldoG]
at cnr-loa we are in touch with WordNet developers and we are working on an OntoWordNet
13:37:51 [danbri_dna]
guus: could restrict this activity... do it so it worked for stuff along lines of the ISO std
13:38:08 [danbri_dna] could have scoping issues such as inclusion of multilingual issues
13:38:16 [bwm]
13:38:35 [danbri_dna]
jjc: a fundamental choice is whether to start w/ general guidelines, or start with an onto owner but do the docs after testing them
13:38:56 [bwm]
13:38:56 [danbri_dna]
mike(? from boeing): former makes more sense... why start without input from others?
13:39:11 [danbri_dna]
ChrisWelty: re wordnet, the work on conversion wasn't done by the vocab owners
13:40:01 [danbri_dna]
danbri_dna: when i did my 99 mapping, i got in touch but they had no resources to help, but were happy
13:40:13 [danbri_dna]
guus: we can negotiate, maybe they could endorse it afterwards
13:40:41 [danbri_dna]
?: two things, converting thes to rdf vocab, vs converting wordnet to a real ontology
13:40:54 [RalphS]
13:41:07 [danbri_dna]
bernard: i agree we need 3/4/5 good use cases...
13:41:14 [danbri_dna]
...what is process to go to src owners
13:41:34 [danbri_dna]
guus: i think v pragmatic material like: is there a big demand for this particular resource
13:41:40 [danbri_dna]
...wordnet figures high in many apps
13:41:52 [danbri_dna] probably no.1 despite its errors
13:42:08 [danbri_dna]

13:43:07 [danbri_dna]
guus: yes, we see questions re thesaurus
13:43:29 [danbri_dna]
jjc: on the subject of wordnet, our colleague Ian has been looking at conversion
13:43:34 [danbri_dna]
...had some specfic question
13:43:41 [danbri_dna] do with whether and how to publish his results
13:44:07 [danbri_dna]
RalphS: is it plausible there's an owner of wordnet?
13:44:13 [danbri_dna]
(several): princeton
13:44:38 [RalphS]
"owner" as in a real person who can work with us
13:44:40 [ChrisWelty]
The owners of WordNet are George Miller and Christiane Fellbaum
13:44:49 [danbri_dna]
guus: although they are resource limited, maybe if we offer to help synetheisse the different proposals, would value that
13:44:59 [danbri_dna]
guus: ericm, any thoughts re getty?
13:45:13 [danbri_dna]

13:45:31 [danbri_dna]
...etc. they have spent much time/effort building systems aroudn their own representations of this information

...when to use rdf, when to use owl, ...
13:46:41 [danbri_dna]
q+ to ask whether Gettty's vocabs would be usable freely in public semweb documents
13:46:51 [danbri_dna]

guus: i'd like to see the rationale for doing this documented
13:48:28 [RalphS]
Guus: note should provide rationale for doing a conversion
13:48:34 [danbri_dna]
em: yup
13:48:46 [danbri_dna]
jjc: are you generalising from many people or just getty?
13:49:10 [danbri_dna]
em: mostly getty but reflecting a general view. Dewey Decimal is another
13:49:16 [danbri_dna]
...similar questions there
13:49:38 [danbri_dna] are there ways of providing access control?
13:50:08 [DanC_jam]

14:20:05 [danbri-scribe]
...i spoke with henry thompson, who suggested the xml schema wg may be receptive right now
14:20:08 [DanC_jam]
hmm... GRDDL + schema-for-schemas = OWL ontology for datatypes?
14:20:09 [timbl]
It is better IMHO to start making a few well-defined concepts like lattitude and longitude than to tr to take some dewey decimal systm of all things and refine it until everything is crisp and clean.
14:20:18 [danbri-scribe]

14:23:04 [danbri-scribe]
guus: next bit of agenda
14:23:14 [aldoG]
back to DMOZ, the point is that DMOZ is a topic hierarchy, and the notion of topic is different from that of class ... I don't want to overprecise things, but imo one best practice is clarifying what a terminological resource is made of in terms of data types ...
14:23:18 [danbri-scribe]
jjc: this isn't the last opportunity!
14:23:51 [danbri-scribe]

I am saying that generic ontologies (time, persons, plans, space, etc.) are something that should be used as ontology design patterns, if appropriately formatted, then a sharp distinction is a bit artificial ...

Discuss "backbone of ontology" (missed details)
15:36:25 [gk-scr]
... counts as "best advanced practice"
15:36:32 [aldoG]
more exactly, to identify the most stable part of a taxonomy (so-called 'rigid properties'). which sometimes is not the most central one btw
15:37:02 [gk-scr]
Chris Welty indicates willingness to sponsor "ontology backbone" note
15:37:43 [gk-scr]
DL/Frames/FOL... note needs broader view?

15:39:57 [ChrisWelty]
15:40:30 [gk-scr]
Ralph: whetever we work on/with, be approachable to people *here* (W3C) who use semantic web technologies. Deep use of ontology community concepts could be off-putting. Try to translate, not-reinvent.
15:41:42 [gk-scr]

Guus: (personal view) technically not diffiult to map TM to RDF. TM is more like info searching paradigm; correspond to a particular way of using RDF.
16:26:25 [gk-scr]
... first step to write note about this worldview notion, and what it means in SWeb terms.
16:26:34 [gk-scr]
... no so much technical issue
16:27:02 [gk-scr]
... show how to do same thing with diofferent underlying representation, we have a link

16:27:12 [danbri_dna]
ack danbri_dna
16:27:12 [Zakim]
danbri_dna, you wanted to note a swad-europe workshop planned for April18th, alongside XML-Europe in Amsterdam (as yet unannounced)
16:28:33 [gk-scr]
Bernard: we have three days of meetings, is overlap, we will not attend.
16:28:45 [gk-scr]
danbri: formal annoucnement awaits further checks
16:29:26 [gk-scr]
Bernard: TM people want clear indication that there is an interest in (cooperation) ... if there is one
16:29:44 [gk-scr]
... people say TM in SWEB, but not written anywhere
16:30:33 [gk-scr]
Ralph: mentioned in a couple of places; is there in this group desire to work on the mapping?
16:30:39 [JosD]
Re Topic Maps Data Model - Committee draft 2003-11-02
16:30:59 [gk-scr]
... e.g. GRDDL mapping style of approach
16:31:48 [gk-scr]
Bernard: if you can map, people ask "why two technologies, get rid of one".
16:32:05 [gk-scr]
Jos: does TM have model theory
16:32:14 [gk-scr]
Bernard: no. standard is data model.
16:33:14 [gk-scr]
Guus: write a note ... what does it mean ... (not following detail here)
16:33:50 [gk-scr]
Bernard: RDF has ben supported by good formal logic people; no such in TM community
16:34:33 [gk-scr]
Guus: TMs have ben successful for certain user communities .. building common index streams to find documents, mostly intranet based.
16:34:57 [gk-scr]
16:35:33 [gk-scr]
Bernard. DanBri will help to find people. Guus wants to, but... (a day has only 30 hours)
16:35:55 [gk-scr]
Ralph: I want to see progress. The conversation is long-running.
16:36:23 [danbri_dna]
aside: [[
16:36:24 [danbri_dna]
Bring together existing and new developers working on interoperability between RDF-based and Topic Map-based datasets, applications, systems and services.
16:36:24 [danbri_dna]
Explore ways of exposing RDF vocabularies (including OWL ontologies) within Topic Maps environment (and vice-versa)
16:36:28 [danbri_dna]
Encourage practical, test-case led framework for cross-technology interoperability
16:36:28 [gk-scr]
... are there practices we can examine, or is new work needed? Latter seems beyond a SWBP task force
16:36:32 [danbri_dna]
Discuss implementation lessons learnt.
16:36:36 [danbri_dna]
Share this information to the wider community.
16:36:38 [danbri_dna]
16:36:40 [danbri_dna] the workshop draft I have
16:37:10 [gk-scr]
jjc: Good if Mondeca nd ANO are using the same mapping.
16:37:20 [gk-scr]

[ontopia folks have done works on mapping too]
16:38:41 [gk-scr]
RDF data model very like binary relational model.
16:39:09 [gk-scr]
What relations are there between RDF and SQL query techniques, and other aspects. (Excpet query out of scope, to DAWG)
16:39:35 [gk-scr]
jjc: Chris Bizer works in this area.
16:40:47 [gk-scr]
Maybe Alain Lege interested
16:40:50 [danbri_dna]
[libby, dajobe, what was that swad-e report that covered sql to rdf mapping stuff? or in several docs?]
16:40:52 [RalphS]
Ivan: RDF comes up in discussions as a general data model to combine large databases
16:42:03 [danbri_dna]
q+ to note that DA WG will be pretty close to this space due to the xquery relationship
16:42:20 [gk-scr]
DaveB: Swad europe, workshop and two reports. What else to say/do? mapping RDBs/ontologies.
16:42:28 [libby]
here's one:
16:42:45 [gk-scr]
ChrisW: different issues: RDF for DB integration and what is relationship between RDB and triples
16:43:20 [danbri_dna]
thanks libby
16:43:32 [gk-scr]
jjc: two kinds of DB integration: (1) integrate with RDF (map the triples), (2) integration by OWL, be much smarter.
16:43:40 [danbri_dna]
16:43:41 [danbri_dna]
A public report on mapping triple stores and RDBMS concentrating on surveying the schemas used and discussing mapping approaches to and from relational schemas.

thanks zakim
16:45:38 [gk-scr]
danbri: t get sweb kick-started, taking relational databases and presenting them as RDF sems to be of some value. Part will be addressed by new DAWG. Guys wrapping XML around relational data mostly using XQuery. DAWG will look at maop to XQuery.
16:46:02 [gk-scr]
... suggest concentrate this group on other things, but keep talking to DAWG.

16:47:09 [libby] see refs e.g. (I'm sure eric's done more recent stuff too)
16:47:55 [gk-scr]
ChrisW: two issues; one to throw to the DAWG, the other is database integration and this has great value. Using RDF to specify database schema semantics, seems to lie in SWBP purview.
16:48:09 [gk-scr]
Ralph: but what can we do in 4-6 months.
16:48:28 [gk-scr]
ChrisW: lots of work in description logics community.
16:49:07 [gk-scr]
jjc: Suggest postponing this: OWL is new and exists prior art in DL community which will hopefully\emerge into SWeb in any case.
16:49:27 [gk-scr]
ChrisW: I don't want to lose it; OK to postpone.
