14:20:24 ...build from broken HTML; apply a parser like transformation; written in PHP 14:20:32 Harry: Throw me a link to that 14:20:42 ...We support XSLT because that's what everyone was using 14:20:51 ...we could use PHP methodology to test 14:20:57 Ivan: Do we have a GRDDL engine? 14:21:15 Harry: No, all the test cases are written using XSLT; I can ask Andy and Dave Beckett 14:21:29 ...not sure how difficult it would be to call an [] processor 14:21:48 Bengee: If it doesn't work; one issue I had was deciding how to transform microformats to RDF 14:22:10 ...from SWEO perspective, we could point people tomappings for selective vocabularies; get the same output 14:22:46 Harry: Microformats in theory, no resistence from community to use GRDDL; but what needs to be done is stabilizing the RDF mapping of the microformats 14:22:54 hCal microformat 14:22:56 ...often the RDF vocabulary is unclear 14:22:58 RDFCalendar 14:23:03 ...map into RDF calendar 14:23:06 q+ 14:23:09 ...I haven't seen much coming out 14:23:15 ...wonder if SWEO is monitoring that 14:23:20 Kingsley: I use it 14:23:35 Ivan: Action Bengee, please send references on PHP to Harry 14:23:39 action: bengee to send references of the PHP stuff to Harry 14:23:56 Bengee: Are you using XSLT?

14:26:07 Harry: you can put link to XSLT 14:26:21 ...get everyone to support that; name space document so you don't have to add a transform 14:26:29 ...transform to RDF without additional work 14:26:48 Leo: Inform people about name space document 14:27:03 Harry: may be easier to do that than go after document producers directly 14:27:09 ...get network effect of key users 14:27:13 Atom - Danny Ayers 14:27:16 ...Danny Ayers is looking at Atom 14:27:21 ...Dublin Core would support 14:27:22 Dublin core said they support it.. 14:27:27 hCard 14:27:33 ...already supports it 14:27:40 Ivan: Where are we with stable V card?

14:41:51 Harry: Part of job as SWEO is outreach, yes? 14:42:00 To outreach to actually makes these use-cases. 14:42:04 Revyu 14:42:09 ...by Tom Heath 14:42:18 Someone to stabilize for RDF review vocabulary 14:42:27 ...his site uses Microformats 14:42:41 ...that would make mixing reviews a real-world use case with real live data 14:42:46 ...anyone could use and find useful 14:43:07 http://revyu.com/ 14:43:11 ...As GRDDL winds down, we have limited resources now; perhaps someone can contact Tom 14:43:26 Ivan: We are talking different things 14:43:29 we could publish a challenge: grddlize a website and prove of some useful thing that can now be done 14:43:32 HP does with GRDDL internally? 14:43:46 Ivan: In which operation is GRDDL already used? 14:43:47 The only organization that uses GRDDL internally is the W3C. 14:43:58 Outreach the problem. 14:44:00 q+ 14:44:01 GRDDL Rec status. 14:44:17 HarryH: OpenLink uses GRDDL in it's Sponger Middleware 14:44:18 ...it just reached rec status; if SWEO had spare cycles, it would be good use of time 14:44:22 ...I don't know of some 14:44:23 ack leo 14:44:27 Leo: What we could do 14:44:35 ...pose another challenge for a community project 14:45:18 ...people blog about it 14:45:37 Harry: There are several large calendaring sites that use Microformats 14:45:47 Kingsley: Upcoming, Eventful 14:45:54 Eventful and Upcoming use micro-format? 14:46:01 Use the profile URI in their website? 14:46:04 Harry: Yes, these are microformat based; could be useful to ask if they want to use profile URI in Web site 14:46:11 That would be more real data. 14:46:18 Leo: One page abstract of how it works would be good 14:46:25 ...then we publish this as a challenge 14:46:27 we need the profile URLs first, though 14:46:29 ...hope a small hacker does it 14:46:37 sweo is not really producing code 14:46:45 Kingsley: I think there is a Firefox plug-in for GRDDL? 14:47:08 Firefox plug-in creators in SWEO - Operator is supported? 14:47:22 Harry: Another way to do it, contact people who run Eventful and Upcoming directly 14:47:27 ...they have contact pages 14:47:28 Contact Eventful and Upcoming.org directly? 14:47:35 ...no, we don't have personal contacts to them 14:47:45 +1 for contacting the eventful and upcoming people, thats nice 14:48:19 Kingsley: What I think we need is somebody to do a plain English demonstration 14:48:25 ...of how GRDDL exposes the dataweb 14:48:30 all: http://www.openlinksw.com/dataspace/kidehen@openlinksw.com/weblog/kidehen@openlinksw.com%27s%20BLOG%20%5B127%5D/1258 14:48:32 ...here is link of guy 14:48:44 http://www.commoncraft.com/video-social-networking 14:48:52 ...let's look at social networking 14:48:56 ...I spoke with this guy 14:49:05 ...If we can get him to take something simple to demonstrate 14:49:07 Contact Eventful: http://about.eventful.com/contact.html 14:49:12 ...show how SW can crystalize 14:49:20 ...that would be great education and outreach 14:49:23 ...watch the clips 14:49:26 Harry: yes, I'll look 14:49:50 ...One-page challenge; contact people would be good 14:49:55 Ivan: So question is, who is that? 14:50:05 ...who can write this challenge text? 14:50:18 Kingsley: I don't think that's the issue 14:50:38 ...Impact of GRDDL is not new, just needs more collateral 14:50:44 Harry: People just need to know about it 14:51:04 Kingsley: Challenges are not way to convey the message; it's about communication 14:51:24 Ivan: You have to have people know how to use it in practice 14:51:39 ...challenge idea is that someone comes up with a challenging implementation of some ideas; then add those lines 14:51:54 Kingsley: I don't know how many people on this call have looked at the GRDDL work 14:51:58 ...I don't know who will respond 14:52:07 ...who can produce anything better? 14:52:23 Harry: Get current Web sites that are Microformat supported, you can blog about it 14:52:51 Kingsley: Get users to adopt, have to show value 14:53:00 Harry: XTech used it after we contacted them 14:53:07 ...they GRDDL-enabled their pages 14:53:12 http://2007.xtech.org/public/news 14:53:14 ...to them it's a few minutes of their time 14:53:22 Adding profile @? 14:53:25 Very simple 14:53:37 Ivan: Problem is XTech; those are hackers; we have to convince people outside that circle 14:53:51 ...that it's worthwhile to do; provide convincing things they can do with it 14:53:59 ...challenge idea of Leo is in this direciton 14:54:07 Harry: I have five more minutes 14:54:20 ...I would support a challenge if someone else writes it up 14:54:35 ...someone should ping players who support microformats; ask to add profile to their site 14:54:52 HarryH: Do you have list of web hubs that you would like to incorporate GRDDL? A list will help 14:55:04 ...if anyone does get XSLT; read primer, how to GRDDL upgrade XML vocabulary 14:55:10 ...Eventful is first on my list to contact 14:55:21 Ivan: ditto re. players that you think would need convincing etc? 14:55:21 ...Flickr supports 14:55:29 one problem is that even individual (low-size) sites are reluctant to add profile URLs to their personal mf-enabled sites 14:55:41 Revyu? 14:55:54 Ivan: who thinks they can write the challenge text? 14:56:06 ...or we can ask on mailing list 14:56:23 Ivan: Bengee, can you write email to SWEO list? 14:56:24 HarryH: Revyu we can deal with once we have the Ontology etc.. 14:56:37 LinkedIn uses hResume, but we don't have a Resume RDF vocabulary to my knowledge.. 14:56:49 Action Leo: write to SWEOmailing list 14:57:01 Ivan: next, we have to write contact persons 14:57:15 HarryH: Uldis has a Vocabulary that may be useful 14:57:23 we need a non-microformats use case that shows GRDDL's utility 14:57:43 Kingsley: Give me the names and I can contact them 14:57:58 ...make a list 14:58:24 Harry: Dan Connolly has talked to people at LinkedIn 14:58:24 Revyu, LinkedIn, Eventful, Flickr. I just don't know names. I'd e-mail Dan Connolly and e-mail Brian Suda about the Web 2.0 services. 14:58:37 Ivan: Would it be possible to put it on the GRDDL group call? 14:58:44 -PaulaP 14:58:49 Harry: What's needed is for one person to be the contact point 14:58:59 ...keep pressing this person 14:59:03 -LeeF 14:59:15 We'll try to get a list from the next GRDDL WG. 14:59:30 Action: Harry will take to next GRDDL meeting 14:59:36 Ivan thanks Harry 14:59:52 ...SW logos are out 15:00:00 ...I have updated the Activity page 15:00:04 ...I'll add it to the blog 15:00:12 ...this is done, it's a good job 15:00:20 ...meeting adjourned 15:00:21 - +1.603.897.aabb 15:00:22 -Harry 15:00:22 -??P26 15:00:24 -bengee 15:00:26 -uldis 15:00:27 -Leo 15:00:57 RSS Agent, please generate minutes 15:01:25 RSSAgent, please generate minutes 15:01:47 RRSAgent, please generate minutes 15:01:47 I have made the request to generate http://www.w3.org/2007/10/10-sweo-minutes.html Karen 15:02:13 -Karen 15:02:15 SW_SWEO()10:00AM has ended 15:02:19 Attendees were Ivan, Karen, LeeF, bengee, Harry, PaulaP, Melli, Leo, uldis 15:16:14 kidehen has left #sweo 15:16:38 bengee has left #sweo 15:45:32 LeeF has left #sweo 16:54:29 Zakim has left #sweo 18:15:35 ivan has joined #sweo 18:41:40 Karen has left #sweo
