Detailed minutes
This first item is a change in how minutes are taken. The scribe is to
be responsible for formatting the minutes to enable to post them on
the W3C web site.
Agenda review Approval of minutes face to face formal Liaison with
DAML organization dive in to pick up to review goals from each of the
champions request for discussion of Reliable and predicable of web
services. (not covered due to time constraints)
3. Approval of [6]minutes from last week
no objections were voiced.
Hugo: there were questions about security do people have anything to
say about the minutes.
Suresh: he asked what was recorded and what was recorded seemed to
differ from what people remember. No real concern.
Chris: minutes approved. They will be posted to the web page.

5. Status reports:
Face to face - 33 people signed up. attending or regrets - conference
bridge has been set-up Teleconference is available. we are looking to
have a groups dinner Tuesday night. So early arrivers can attend the
dinner. Members of the architecture group can attend the other WG's
dinner on Wednesday. people need to register by April 1 in order to
have enough food and other materials available at the meeting. The
agenda of the F2F will be available shortly.
Future F2F - in the 2nd week of June - in France - trying to nail down
hosting details. Hugo mentioned that Canon sent a note regarding that.
Hugo and Chris were waiting on each other for a note. can someone pay
for this meeting? the amount is about 4000 euros. This would in in
Brittany near the Canon facilities. If you can cover the cost contact
Hugo or Chris. There was discussion in the coordination group of a
vacation mouth in August. Chris was in favor of that. We are going to
take the month of August off. We will resume in September. On the
timing in June: the Soap group is having a meeting the first week of
June.
Editing team report:
Daniel - they met Wednesday - to publish a requirements document
tomorrow. All of the things Chris mentioned will be included. This is
one prior version before the face to face. A lot more text and "flesh
on the bones" there will be one more to be published before the F2F.
Comments need to be in by the 25th of March. Anyone with threads try
to provide summaries by March 25th. This is so that these threads will
be considered at the F2F.
Joe: is there any leeway on the closing day do to schedule conflicts.
Tracing mail threads can be difficult.
Daniel: Champions for each thread need to get their summaries ready
for submission. The sooner we can get the summaries in the better we
can be prepared. Joe is the champion of #6. The editors figured out
what was with the issues list. This was sent to the mailing list.
Daniel - all summaries need to be in by the 25th to have it ready for
the F2F
6. DAML initiative liaison
Katia Sycara has joined the call this week. She introduced herself.
She is at Carnegie Mellon. DAML+OIL for semantic annotation of the web
DAML+S an ontology and components for describing invoking services.
BBN, Nokia, Stanford, and Yale among others are involved. Two review
documents are published. They are at www.DAML.ORG/services They are
aiming to publish in a month this is an ontology - a web resource can
provide a services: it has a service profile describing what it does
to advertise their services with a registry. A service model provides
what a service does a service grounding describes how to use it. The
service profile. provider, name, QoS or rating. The process model and
profile have inputs and outputs. She gave a description for how these
could be used. (Thompson) How are things described, is there a
semantic framework? the "holy grail" the matching is in form of
keywords and semantics. with tokens and strings - if the service is
well described not everything has to match. there is a DAMLS matching
tool with partial matching. This is to operate on top of UDDI. UDDI
does not provide any of these capabilities. This semantic matchmaker
will operate with UDDI. If you have questions send them to Katia. How
does this description language differ from other description
languages? How does this relate functionally or hierarchically with
other description languages? description logic or ?? there are a
number of functional choreography ;languages fit in. ebXML -m not just
a language - DAML+S is on top of RDF. If you have further questions
contact Katia Sycara at katia@cs.cmu.edu
7. Continue review of Goal Summaries
DG#3
Suresh: in regarding goal 7 - was that finished at the last
teleconference?
Chris: goal 7 - that was not really concluded, but it was continuing
being discussed. What is needed to conclude it. It needs to be
resummarized. The summary of the threads should be: a combination of
what are the different view in the threads and the success factors
related to that goal, then part of the out come would be a refined
phraseology.
Daniel: The editors would like to have the agreed on final wording of
the goal, what are the success factors and requirements - in addition
to a diagram (similar to what was created for goal #1 and Goal #2)
There would be a proposed wording and the editors would approved. the
diagrams were posted to the working group by Daniel. A picture is
better than words to see how it works. These diagrams are simple Visio
diagrams. Daniel went on to say to put some boxes together - as in an
org chart for requirements. Daniel would like to have comments on #1
and #2. These are stakes in the sand.
Nilo: #3 - not much e-mail on #3 - to develop a standard architecture
for web services that is sufficiently extensible for future expansion-
separating transport from what web services are or what they do.
descriptions should separate design and run time aspects. Allowing
extensibility. Make extensible to enable future business goals. This
should not impede adoption of further interactions and to handle
future business goals. We need to enumerate facets of W/S - what are
the aspects. What are the other blocks to allow the extension and
addition of web services.
Daniel: we should anticipate changes so aspects can be added to web
services, things we have not yet thought of. Don't make the
architecture rigid. We need separation of what from how. The
architecture should not require that you can not do certain things. In
addition we should not depend on the current state of the web.
Situations change, business goals change, web services should be able
to change to support future need. we can not know the future. Separate
the abstract from concrete. The architecture should be able to be
changes no explicit dependencies on the current situation. We need to
create an architecture that allows for change. Leave room in your
architecture for change.
Nilo: last question - how is this different from #7 - predicable
evolution of architecture. technology and business goals. How would it
look to combine #3 and #7? this was a proposal. #7 was intended as a
well defined way of change management. not for extension of the
architecture.
Chris: we need to come to an agreement
Chris: #8 - Tim Jones is not on the call - no traffic in regard to
this. he asked if the architecture is complete and self-contained. is
this the notation for describing the architecture. the original goal
are coherent and consistent. for parts to work together - and
consistent - there is a common protocol for communications. It was
suggested that Daniel and Tim discuss this. Continue discussion to
this on the list. mike man- "in its definition" how we notate its
definition. there was no intent for specific notations. Consistency of
the architecture was discussed. Coherency and consistency is seen as
important.
MikeM: This may overlap with #11
Mike: #11 - the current wording was read. - basically - to work with
existing web architecture heterogeneous environments. This may overlap
with semantic web goals. Semantic web is in planning, we have to be in
tune with the current web, but not to go against what semantic web to
working toward. There is some overlap with #4 platform independence
and heterogeneous environments are similar.
Abbey: Mark Baker is discussing this with current looking and future
looking. What is the implication of #11 and #4 separate, we know how
the current architecture works, but we are not aware of how the
semantic web will work. They have some frameworks, but not an
architecture. We need to concentrate on what works now, and we also
need to make sure that we are compatible with the future semantic web.
MarkB: it is not as clear cut as current looking and future looking.
we need to be in sync with both.
Hugo: the semantic web people argue for semantic models for what we
are doing, as long as both goals are met we are safe. Making the
difference between the old web and the future web we need to address
both at the same time.
Daniel: we need to do them both. We need to know what is the tension
between what one has and what the other does not have. The semantic
web will provide additional functionality. What will be different in
the future? what are the contradictions? It's OK to have two separate
goals as long as we have both of them. Do we need to make them a
single goal? Semantic web is still emerging. We need to be careful of
what are the priorities and requirements. We may need to have give and
take on what we are developing, how could these be joined? or should
they be? This Could be a topic for next week-s call. Mark and Mike
thought this was more of a management task. more opinions are welcome
on this topic. If the semantic web is a superset they need to be
backward compatible with the current web. What are supersets and
intersections between web services, the current web and what is seen
as the semantic web. DAMLS is an offshoot of the semantic web. Are
semantic web people developing a reference architecture?
Daniel: they are not that far along it is not very well defined. How
can we work with their architecture if they do not have an
architecture? We do not have to do every goal at once, we may not be
able to work this goal until later, since we do not know their
architecture, but we need to be flexible to accommodate their future
architecture. To be aligned with their architecture as well as to be
compatible with what they are producing.
it is 13:28 (Pacific daylight time) we are running out of time.
Hugo: The semantic web group is paying attention to what we are doing
here.
??: At the F2F we need to have a talk about the semantic web. we need
to follow what they are doing.
Chris: we will have something on this. Each of the members will need
to examine semantic web information to understand what they are doing
and how it effects what we should or should not be doing.
Chris: urged people to review the summaries of the goals posted in the
agendas each week. We need to make the best use of the list and the
teleconferences.
