15:19:22 [Zakim]
agendum 6. "Mime Types" taken up [from ChrisW]
15:19:46 [StellaMitchell]
cw: Sandro put the mime types in BLD. Has anyone reviewed?
15:19:55 [StellaMitchell]
harold: yes, it looks good
15:20:11 [StellaMitchell]
cw: do you need any changes?
15:20:29 [StellaMitchell]
harold: no, it's fine. Security is an open ended topic.
15:21:03 [StellaMitchell]
harold: he talks about documents that come by dereferencing, but not about other things such as computaiton that does not end
15:21:20 [DaveReynolds]
Surely the current wording addresses both?
15:21:24 [StellaMitchell]
harold: so, he picks one particular example, but doesn't mention other cases
15:21:52 [StellaMitchell]
cw: are you talking about implementations or specific rule sets?
15:22:08 [MichaelKifer]
MichaelKifer has joined #rif
15:22:33 [StellaMitchell]
harold: yes, he doesn't mention rule sets that will cause compuation that doesn't end
15:22:43 [Harold]
Sandro mentions: "Through the use of "import", it may
15:22:43 [Harold]
also require arbitrary URI dereferencing, which may consume
15:22:43 [Harold]
all available network resources on the consuming system or
15:22:43 [Harold]
other systems."
15:22:49 [StellaMitchell]
daver: I think the current text covers that case
15:23:07 [StellaMitchell]
cw: yes, I also think is does
15:23:51 [StellaMitchell]
harold: ok
15:24:01 [Zakim]

cw: any other comments on mime type?
15:24:33 [ChrisW]
zakim, take up item 7
15:24:33 [Zakim]
agendum 7. "Casting" taken up [from ChrisW]
15:24:38 [MichaelKifer]
zakim, mute me
15:24:38 [Zakim]
MichaelKifer should now be muted
15:25:12 [StellaMitchell]
cw: axel, can you summarize this issue?
15:25:38 [StellaMitchell]
axel: in the DTB document, section 4.3 cast and conversion functions
15:26:07 [StellaMitchell]
axel: casts from and to rif:iri - do we want these, and how should we do them
15:26:15 [Zakim]
15:26:28 [StellaMitchell]
...and there was also a question about from rif:text to string
15:26:49 [StellaMitchell]
....first, we have to wait until we resolve rif:text with owl working group
15:27:02 [StellaMitchell]
...should conversion take only the string, or the string with the language tag
15:27:11 [StellaMitchell]
...both would be fine, currently only take the string part
15:28:09 [StellaMitchell]
... rif: iri (4.3.5 and 4.3.6) function style is possible in one direction, if we define axiomatic equalities (4.3.5)
15:28:14 [AdrianP]
AdrianP has joined #rif
15:28:32 [StellaMitchell]
... but this is not possible in the other direction, because the axioms would cause inconsistencies
15:28:43 [josb]
15:28:50 [StellaMitchell]
... I prefer functions wherever possible, and predicate only where function can't be used
15:29:14 [StellaMitchell]
.... (as opposed to making from and to rif:iri both predicates)
15:29:33 [ChrisW]
ack jos
15:29:48 [StellaMitchell] and jos said the predicate will cover both directions of casting
15:30:27 [StellaMitchell]
jos: yes, the function is redundant, and another argument against 4.3.5 is that is is not a function in the way that the other casting functions are, because rif:iri is not a data type
15:31:16 [StellaMitchell]
axel: I agree that what you say is true, but still want to leave it the way it is
15:31:57 [StellaMitchell]
jos: simpler and more understandable to have the one predicate
15:32:14 [StellaMitchell]
cw: are you arguing to use this method for all cases?
15:32:21 [StellaMitchell]
jos: no, just rif:iri
15:32:26 [AxelPolleres]
15:32:31 [StellaMitchell]
cw: what about doing it for all?
15:33:03 [StellaMitchell]
jos: possible, but maybe not natural, because we are following xquery, and because they are actually functions
15:33:17 [StellaMitchell]
...but I still wouldn't be completely against it
15:33:46 [StellaMitchell]
axel: predicates makes writing things more complicated
15:33:55 [ChrisW]
ack axel
15:33:57 [StellaMitchell]
cw: any other opinions?
15:34:31 [MichaelKifer]
I agree with Jos.
15:35:08 [ChrisW]
zakim, who is on the phone?
15:35:08 [Zakim]
On the phone I see Dave_Reynolds, ChrisW, LeoraMorgenstern, josb, Harold, StellaMitchell, AxelPolleres, MichaelKifer (muted)
15:35:31 [ChrisW]
Axel +1, Jos -1
15:35:34 [StellaMitchell]
cw: straw poll,
15:35:41 [josb]
15:35:42 [DaveReynolds]
15:35:44 [AxelPolleres]
Strawpoll: Keep 4.3.5: +1 drop: -1

15:35:53 [StellaMitchell]
15:36:32 [AdrianP]
15:37:02 [StellaMitchell]
cw: I will put this in the form of a proposed resolution (jos's proposal) and let people know that we'll be voting on it next week
15:37:36 [StellaMitchell]
jos: what about between rif:text and strings?
15:38:16 [StellaMitchell]
jos... the issue is from rif:text to string. according to current spec, you lose the language when casting from rif:text to string
15:38:23 [DaveReynolds]
15:38:24 [Zakim]
15:38:39 [StellaMitchell]
...but the other direction is only defined for strings that have language id embedded
15:38:50 [ChrisW]
adrian is that you?
15:39:23 [AxelPolleres]
casting from string to numbers is also not round-drippable... "0001"
15:39:30 [AdrianPa]
AdrianPa has joined #rif
15:39:36 [StellaMitchell]
daver: casting from text to string, using only the string part make sense to me. but is there also a 2 argument constructor to create a string, and also an extractor to get the lang from the string
15:39:55 [StellaMitchell]
jos: I think we don't have the constructor
15:40:02 [AdrianPa]
Zakim, who is on the phone?
15:40:02 [Zakim]
On the phone I see Dave_Reynolds, ChrisW, LeoraMorgenstern, josb, Harold, StellaMitchell, AxelPolleres, MichaelKifer (muted), ??P8
15:40:12 [AdrianPa]
Zakim, ??P8 is me
15:40:12 [Zakim]
+AdrianPa; got it
15:40:18 [AdrianPa]
Zakim, mute me
15:40:18 [Zakim]
AdrianPa should now be muted
15:41:09 [StellaMitchell]
axel: I don't agree with the roundtripping argument because (?)..... and also then it would be complicated to get out the string part
15:41:42 [AdrianPa]
sorry, dropped out. I'm currently travelling and do not have a stable line
15:42:03 [StellaMitchell]
jos: I now agree with dave's idea that we change the cast in 4.3.4 to take 2 arguments
15:42:36 [StellaMitchell]
jos: ...first literal string and second language tag
15:43:20 [StellaMitchell]
cw: I agree that current cast doesn't really make sense
15:43:23 [Zakim]
15:44:01 [StellaMitchell]
axel: it comes from the presentation syntax, it would be easy to implement for the presentation syntax
15:44:27 [StellaMitchell]
axel: yes, I agree to change 4.3.4 to 2 argument version
15:44:33 [ChrisW]
action: change 4.3.4 to a two arg function (string,lang)
15:44:33 [trackbot]
Sorry, couldn't find user - change
15:44:49 [ChrisW]
action axel: change 4.3.4 to a two arg function (string,lang)
15:44:49 [trackbot]
Created ACTION-542 - Change 4.3.4 to a two arg function (string,lang) [on Axel Polleres - due 2008-07-15].
15:45:12 [StellaMitchell]
axel: I think we should add a shortcut for rif:text then, in the presentation syntax
15:45:33 [StellaMitchell]
jos: that was discussed at length at f2f10, with no agreement
15:45:59 [StellaMitchell]
jos: also, 4.7.1, axel and I disagree over the name of the extraction function
15:46:27 [StellaMitchell] is inconsistent with the rest. I think it shojuld be called lang-from-text
15:46:49 [StellaMitchell]
axel: the others come from xquery, this one comes from sparql
15:47:09 [StellaMitchell]
...but I could live with jos's naming
15:47:21 [StellaMitchell]
jos: it's all caps in sparql
15:47:37 [StellaMitchell]
axel, cw: sparql is not case sensitive
15:49:24 [DaveReynolds]
15:49:30 [StellaMitchell]
cw: straw poll

axel: jos and I agreed to put editor's not on things we don't agree on, and get comments from external reviewers
15:51:34 [josb]
15:51:38 [StellaMitchell]
cw: other issues on casting?
15:52:06 [StellaMitchell]
jos: in the above DTB section, inconsistence in names
15:52:29 [StellaMitchell]
...which is intended?
15:53:05 [StellaMitchell]
axel: can I fix this even though wiki says the document should not be changed
15:53:21 [StellaMitchell]
jos: it's just a simple editorial change
15:53:47 [StellaMitchell]
jos: the one in the schema is the correct name, right?
15:53:59 [StellaMitchell]
axel: yes
