zakim, whos talking

17:14:29 [Zakim]

I don't understand 'whos talking', joerg

17:15:56 [cygri]

cygri: does the report on changes have to include editorial stuff, beautifying etc?

17:16:07 [cygri]

ivan: well, no one is *really* interested in that

17:16:12 [joerg]

Ivan: stresses importance of chasing last call comments

17:16:36 [cygri]

cygri: should we chase up commenters who didn't acknowledge our response?

17:16:59 [cygri]

ivan: would be good, but of course there will always be some who don't reply

17:18:40 [joerg]

ashok: eric and richard are both here to discuss the topic

17:18:53 [cygri]

and also: http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2011Nov/0048.html

17:20:29 [joerg]

richard: first links is the reaction to the break down of the problem

17:20:46 [joerg]

richard: canonical form is opposed beacuase of implementation cost

17:21:34 [joerg]

richard: sql recipes are not welcomed as normative definition

17:22:18 [joerg]

richard: new proposal: both canonical and not necessarily canonical form

17:23:06 [joerg]

richard: for literals-> not necessarily canoncial, resources -> canonical

17:26:16 [Ashok]

s/resources/IRIs/

17:26:35 [joerg]

richard: r2rml leaves iri creation to implementors , sql recipies get imformative

richard: dm has to be stricter

17:29:50 [joerg]

richard: canonical literals can be harder to read

17:30:11 [Ashok]

ack next

17:30:11 [ivan]

ack dmcneil

17:32:50 [cygri]

david: what happens in the case where you turn an integer column in a language-tagged literal?

17:32:55 [cygri]

... do you canonicalize there?

17:33:02 [cygri]

cygri: it's kind of the same case as with IRIs

17:33:07 [cygri]

... and there are more

17:33:17 [dmcneil]

e.g. blank node identifiers

17:35:15 [dmcneil]

q+

17:40:40 [cygri]

david: how do we ensure that INT 5 and BIGINT 5 are translated to the same thing?

17:40:53 [cygri]

... the spec needs to nail that down

17:42:12 [joerg]

ashok: what about the implementation costs

17:45:35 [joerg]

richard: don't bother the users to much which problems most likely not to be happening to often

17:46:08 [joerg]

richard: but reagrding to bigint 5 and int 5 problem, most importantly, the result should be conistent

17:49:21 [ericP]

joerg: do we require SQL or XSD canonicalized form?

17:51:10 [Ashok]

In R2RML you can choose not to canonicalize

17:51:15 [joerg]

richard: it is a should, so the implementer is free to stick to it.

17:52:06 [joerg]

richard: and most of the work is already done, by having examined the differences

17:52:34 [joerg]

richard: so the difference is not so big

17:53:31 [ericP]

joerg: from an implementor's perspective who tries to do as much as possible in the database, XSD could be a costly choice

17:54:02 [joerg]

richard: query execution can be done completely in sql space

17:55:02 [joerg]

ashok: can somebody sum the discussion a bit up, Richard?

17:55:30 [ericP]

+1 to 0072 plus amendments

17:55:42 [joerg]

richard: email of today seems consensual

17:56:01 [cygri]

PROPOSAL: resolve ISSUE-69 by adopting proposal at http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2011Nov/0072.html with amendment from david regarding consistent translation of different SQL types that produce same XSD type

17:57:13 [MacTed]

is david's amendment to-be-written? or can it be linked?

17:57:18 [dmcneil]

plus the amendment to say it applies to plain literals as well?

17:57:41 [dmcneil]

and words about blank node identifiers?
