Benji wrote blog-post that was quite critical of RDFa community. 16:19:27 ... He feels that pushing Microdata is a better option for adoption. 16:20:06 ... His past posts of the years are along much the same lines, that the solution should be a collection of tokens, a la Microformats. 16:20:39 q+ 16:20:40 ... We should take his comments seriously, since he represents an identifiable set of concerns. 16:21:30 Ivan: We did discuss the possibility of defining Microdata as a profile of RDFa, and I would be in favour of that. 16:21:51 ... But this post talks of removing things that it doesn't seem possible to remove, such as @resource. 16:22:10 q+ 16:22:11 ... He doesn't really give an argument for removal. 16:22:16 ack ivan 16:22:43 ... Same goes for ranting against CURIEs -- we're working on that and there's not much more we can say. 16:23:06 ... The idea that one set of attribute names is better than another is really a matter of faith. 16:23:29 ... Whilst we don't care that much about the attribute names, a big problem is existing deployments. 16:23:31 ack steven 16:23:32 q+ 16:24:00 Steven: I've been working on RDFa for at least 7 years, and it's not as if it suddenly popped out of nowhere. 16:24:10 ... It had discussion, use-cases, etc. 16:24:29 ... Microdata comes out of nowhere, but somehow it's presented that RDFa-proponents are in the wrong. 16:24:59 ... Appreciate the work of bridge-building, but we have to remember that no-one was asking for Microdata. 16:25:05 q+ 16:25:11 zakim, unmute me 16:25:11 markbirbeck should no longer be muted 16:25:18 ack markbirbeck 16:25:32 zakim, mute me 16:25:32 Steven should now be muted 16:25:51 Mark: I missed the call on Microdata profiles - I think I agree with Steven, I'm not sure I understand what the benefit is. 16:26:30 Mark: We've been working on this for years and Microdata is in flux - and is progressively getting closer and closer to RDFa. 16:27:00 Mark: I don't mind the dialog, but we risk damaging deployment if we change all the attribute names. 16:27:12 Mark: It's sort of religious - one attribute is better than another. 16:27:18 Mark: but there is another way to view this. 16:27:41 Mark: Changing rel to itemprop may be a bad change - @rel and @rev already has a place in HTML. 16:27:54 Mark: We've been very careful to re-use pre-existing semantic elements in HTML. 16:28:49 Mark: Microdata duplicates @rel and @rev - so there is a problem here - that new attributes are being defined for old concepts. 16:29:28 zakim, mute mark 16:29:28 markbirbeck should now be muted 16:29:28 zakim, mute markbirbeck 16:29:29 markbirbeck was already muted, manu 16:30:32 q+ to discuss harm that continued bike-shedding may cause. 16:30:41 zakim, I am [IPcaller] 16:30:41 ok, manu, I now associate you with [IPcaller] 16:30:49 Ivan: Changing attribute names is out of the question. 16:30:51 zakim, who is on the queue 16:30:51 I don't understand 'who is on the queue', manu 16:30:55 zakim, who is on the queue? 16:30:55 I see ivan, [IPcaller] on the speaker queue 16:31:07 zakim, I am +IPcaller 16:31:07 sorry, manu, I do not see a party named '+IPcaller' 16:31:14 ... On the other hand I don't mind about building bridges. 16:31:26 zakim, who is on the phone? 16:31:26 On the phone I see Ivan, [IPcaller], markbirbeck (muted), Steven (muted), ShaneM 16:31:32 zakim IP is Manu 16:31:37 zakim, IP is Manu 16:31:37 sorry, Steven, I do not recognize a party named 'IP' 16:31:47 zakim, [IP is manu 16:31:47 +manu; got it 16:31:51 q? 16:31:58 ack ivan 16:32:09 ack [ 16:32:09 [IPcaller], you wanted to discuss harm that continued bike-shedding may cause. 16:32:29 Manu: I'm increasingly concerned about discussions with people like Wikipedia. 16:33:03 ... The problem was that although we know the background to Microdata popping up from nowhere, the outside world doesn't. 16:33:28 ... They just see a 'fight' going on. 16:33:39 ... I think it's harming adoption. 16:34:52 ... If others implement a Microdata API in the browser, then that could affect adoption. 16:35:30 q+ 16:36:09 ack markbirbeck 16:37:49 Mark: I don't know if a GRDDL-approach, mapping Microdata to RDFa would work... we've had that discussion before. 16:38:13 Mark: I think we should focus on RDFa API and getting RDFa out there more. 16:38:32 I don't think the transform can be isomorphic. 16:38:33 q+ 16:38:42 Mark: RDFa and Microdata are fundamentally not equal. 16:39:20 Mark: This is the same thing that happened with Microformats - RDFa kept going and I think Microformats are coming to an end soon. 16:39:36 ack ivan 16:39:38 zakim, mute me 16:39:38 markbirbeck should now be muted 16:39:57 q+ 16:39:57 Ivan: Wiki would be a good place to start on some of these ideas. 16:40:50 ... (That was response to Mark saying that we should get on and document some of our ideas on RDFa API.) 16:40:52 +1 16:41:16 ... If as Mark says, that RDFa is superior to Microdata, then we should be explaining this. 16:42:15 pre-defined prefixes simplifies immediately 16:42:18 ack manu 16:42:24 ... If someone doesn't want the full functionality of RDFa it should be clear how to use it. 16:43:12 Shane would like it minuted that he is paying attention. 16:43:49 http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2010Jan/0059.html 16:43:50 Topic: RDFa vocabs 16:44:24 Sorry...was foolishly following previous minutes! 16:44:38 q+ 16:44:54 s/RDFa vocabs/Pre-loading prefixes/g 16:44:58 Topic: RDFa prefix pre-loading 16:45:18 Ivan: At a theoretical and technical level, these things are not totally unrelated. 16:45:44 +1 16:45:54 ... They shouldn't need to be presented as being distinct. 16:45:59 zakim, unmute me 16:45:59 markbirbeck should no longer be muted 16:46:27 Mark: One of the things on the vocab front is this gradual rejection that follow-your-nose is everything. 16:46:57 Mark: The idea that everything must be able to be worked out on the fly by default - you need to support follow-your-nose 16:47:15 Mark: But saying that stuff is predefined isn't necessarily a bad thing - we shouldn't be scared of doing that. 16:47:54 Mark: This is where Microdata and Microformats falls down - they don't have the follow-your-nose mechanism. 16:47:59 Mark: RDFa does. 16:48:12 Mark: as long as you can ensure that the two co-exist, then why not pre-load prefixes? 16:48:42 Ivan: Then we largely agree, right? 16:49:19 Mark: The downside to this follow-your-nose is that it is used as an argument against pre-defined vocabs. 16:49:43 zakim, mute mark 16:49:43 markbirbeck should now be muted 16:49:48 Ivan: Google uses the same mechanism... but it has been said all along that a processor would cache a bunch of these namespaces. 16:49:59 q+ 16:50:15 Ivan: caching is a fundamental part of the web. 16:50:21 ack manu 16:50:24 Ivan: Not disimilar to an editor caching DTDs. 16:50:26 I want to do this RIGHT NOW 16:51:17 Manu: But which vocabularies would we put into the spec? Which ones have longevity? 16:51:28 ... Top 20 from CC? 16:51:32 q+ 16:51:40 s/CC/prefixcc/ 16:51:40 ack ivan 16:51:55 q+ to talk about the process for picking vocabs 16:52:13 zakim, unmute me 16:52:13 markbirbeck should no longer be muted 16:52:14 ack mark 16:52:31 Mark: I think we shouldn't be scared of doing this - not do this now. 16:52:50 Mark: We should certainly think all of this stuff through... there isn't a principle that we shouldn't have to pre-define things. 16:53:08 16:53:08 16:53:08 ... 16:53:09 16:53:09 16:53:10

16:53:31 16:53:33 16:54:18 Mark: This approach might be better - since it's encapsulated in a @profile attribute. 16:54:39 Mark: That is better than Microformats and it's scalable. 16:54:49 zakim, mute mark 16:54:49 markbirbeck should now be muted 16:55:16 unmute, mark 16:55:16 ack mark 16:56:44 Mark: This would allow RDFa processors to understand the URL to mean something special. 16:57:17 Mark: It's a key to tell the authors that their data would be processed in a particular way. 16:57:45 zakim, mute mark 16:57:45 markbirbeck should now be muted 16:58:03 Mark: Maybe we should defer the pre-loaded prefixes until we can have this discussion 16:58:19 rrsagent, draft minutes 16:58:19 I have made the request to generate http://www.w3.org/2010/01/28-rdfa-minutes.html manu 16:58:22 q+ 16:58:24 Mark: Not intending to take the discussion in other direction, just trying to point out that there may be something even better than fixing prefix values. 16:58:28 ack ShaneM 16:58:29 ShaneM, you wanted to talk about the process for picking vocabs 16:59:08 Shane: But people forget to use @profile, or they don't have access to , etc. 16:59:10 q+ 16:59:15 ack manu 16:59:30 +1 to Shane's comment 16:59:33 ... So having the ability to use "dc" or "foaf" without having to define it, would be very useful. 16:59:43 ... Let's just do this now. 16:59:53 rule one for picking prefixes. vocabs defined by the W3C are predefined. 17:00:23 -ShaneM 17:00:25 Bye everyone. 17:00:25 -Ivan 17:00:29 -markbirbeck 17:00:30 -Steven 17:00:30 -manu 17:00:31 SW_SWD(RDFa)11:00AM has ended 17:00:34 Attendees were Ivan, [IPcaller], +0208761aaaa, markbirbeck, Steven, ShaneM, manu 17:00:39 me Mark - I'll clean up the minutes 17:00:47 Great...thanks Manu. 17:00:48 zakim, draft minutes 17:00:48 I don't understand 'draft minutes', manu 17:00:54 rrsagent, draft minutes 17:00:54 I have made the request to generate http://www.w3.org/2010/01/28-rdfa-minutes.html manu 17:01:06 Note that omitting @profile is a red herring. 17:01:17 how so? 17:01:27 People raise it, and say that no-one ever used @profile in Microformats. 17:01:30 That's true. 17:01:36 ahh, yes 17:01:38 I see your point 17:01:46 But in RDFa if you miss out all the namespaces you're scuppered anyway. 17:01:57 The reason they didn't use it was because it had no effect on processing. 17:02:00 So there's already a basic requirement on authors to add something. 17:02:05 Yes, exactly. 17:02:33 But if you miss out the Google namespace in your RDFa, you won't get indexed properly. 17:02:40 Same in Yahoo!. 17:03:03 So all we're saying is instead of adding 10 URIs, just add one. 17:03:04 The #seo people will definitely make a point of it 17:03:15 A point of getting it right? 17:03:19 yes 17:03:23 Exactly. 17:03:38 Anyone interested in providing information for some consumer will want to get it right. 17:03:55 rrsagent, draft minutes 17:03:55 I have made the request to generate http://www.w3.org/2010/01/28-rdfa-minutes.html manu 17:04:01 but.... 17:04:23 Present+ Shane_McCarron, Steven_Pemberton 17:04:24 Control over is a fair point though. 17:04:29 Shane is right there. 17:04:31 profile goes on the html element. or the head.
