15:06:30 <ivan> Topic: Link Relations and Microformats Community
15:06:30 <tomayac> ivan: It turns out that HTML5 uses the link relations defined by the Microformats community and not from the IETF Link Types registry, so using the Link Types from the IETF Link Types registry will conflict with the ones that are "officially recognized" by the HTML5 specification.

15:07:52 <tomayac> Manu updates the group on the current feedback from schema.org, the proposed way forward, and the potential impact of the changes on adoption vs. backwards compatability.

Zakim IRC Bot: ShaneM, you wanted to ask about publication process

15:23:01 <tomayac> ShaneM: Does our charter allow us to publish an RDFa Lite 1.1 specification?

Shane McCarron: Does our charter allow us to publish an RDFa Lite 1.1 specification?

15:23:03 <tomayac> ivan: Yes, I believe it does - we're chartered to publish RDFa 1.1 - we can do it as a single document or multiple documents.

Ivan Herman: Yes, I believe it does - we're chartered to publish RDFa 1.1 - we can do it as a single document or multiple documents.

15:23:07 <tomayac> ivan: In the very worst case, RDFa Lite 1.1 could become part of core, as a separate chapter - but we don't want to do that.

Ivan Herman: In the very worst case, RDFa Lite 1.1 could become part of core, as a separate chapter - but we don't want to do that.

15:23:30 <tomayac> ShaneM: that seems like a workable option in the worst case.

Shane McCarron: that seems like a workable option in the worst case.

15:23:44 <tomayac> ShaneM: We also need to publish a working draft of RDFa Core when we do a FPWD of RDFa Lite

Shane McCarron: We also need to publish a working draft of RDFa Core when we do a FPWD of RDFa Lite

15:24:12 <tomayac> manu: The vast majority of the WG is in favor of the property changes - there is only one dissenting opinion and that's from Toby, who hasn't been able to chat with us on the call yet and probably doesn't have the full picture. He does make a number of valid points, but we have discussed counter-points to those.

15:33:21 <ivan> q+

Ivan Herman: q+

15:33:31 <tomayac> manu: the other is to remove @rel from Lite, as it's not necessary for the schema.org or rnews use cases. People can use the newly changed property to support all of the use cases.

15:37:17 <tomayac> ivan: I would not bind Lite exclusively to vocabularies like rnews and schema.org - we want a solution that is broader than that, right?

Ivan Herman: I would not bind Lite exclusively to vocabularies like rnews and schema.org - we want a solution that is broader than that, right?

15:40:23 <tomayac> manu: We want to send a clear message with RDFa Lite - RDFa is easy to use - you only need 3 attributes for the basic markup and 5 attributes if you want to name entities and do vocabulary mixing.

15:40:48 <tomayac> manu1: your @rel chaining use case is still possible with RDFa Lite, Ivan - you just do <div property="foaf:knows" typeof="foaf:Person"> for every person you want to link to. Yes, it's more markup than @rel... but that's why @rel is an advanced feature.

15:54:41 <tomayac> niklasl: Should RDFa Lite mention that it's dedicated for authors, and not implementors?

Manu Sporny: i don't think so

15:55:14 <tomayac> manu1: it just comes across as a simple thing that authors can read. Implementers will know that the document doesn't have enough information in it for an implementation.

3. @rel and @property Symmetry

15:56:24 <tomayac> niklasl: Should @property do chaining if there is a typeof attribute? Why does it do it differently from @rel?

Niklas Lindström: Should @property do chaining if there is a typeof attribute? Why does it do it differently from @rel?

15:56:50 <tomayac> manu1: I think making @rel and @property do the same thing would create a large backwards incompatibility problem.

15:57:50 <tomayac> gkellogg: i think using @typeof to really communicate you want to use chaining is a good thing - doesn't break legacy markup.

15:58:11 <tomayac> ivan: an empty typeof might solve this, but that's a bit of a hack.

16:04:03 <tomayac> manu1: I have a feeling that whenever someone uses more than three attributes on an element with RDFa, it's almost always going to be wrong... which is why we have debuggers.

16:04:55 <tomayac> manu1: This is the basic argument against RDFa... that when you start mixing and matching too many attributes on the same element, it becomes difficult to understand what subject applies to what object - using many attributes in one element causes complexity that you need a debugger to solve. It's a perfectly reasonable argument against RDFa and the response to it should be: If you're not an expert, don't put more than two RDFa attributes on a single element at a time.
