  1. 1. IPTCSemantic WebWorking Group<br />Stuart Myles<br />Associated Press<br />7th June 2011<br />
  2. 2. IPTC SemWeb Working Group<br />Making use of Semantic Web technologies for news<br />Leverage technologies developed by others<br />The work falls into two main areas:<br />Models<br />Determine what aspects of news to represent<br />Formats<br />The details of how to represent the news<br />Using RDFa, microformats, Linked Data, microdata<br />© 2011 IPTC (www.iptc.org) All rights reserved<br />2<br />
  3. 3. IPTC’s Semantic Web Agenda<br />At this meeting we will discuss<br /><ul><li>The rNews 0.5 model
  4. 4. News Metadata in HTML Markup
  5. 5. RDFa
  6. 6. Microformats
  7. 7. Microdata
  8. 8. For vote: rNews Draft 0.5</li></ul>© 2011 IPTC (www.iptc.org) All rights reserved<br />3<br />
  9. 9. News Metadata in HTML<br />One goal<br />Promote the creation of better, more accurate tools for working with news on the web<br />By adding news metadata to HTML<br />(At least) three approaches<br />Microformats<br />conventions for using standard HTML<br />to add labels to indicate the meaning of markup<br />RDFa<br />alter your HTML document to use non HTML attributes<br />to insert RDF triples to indicate the meaning of markup<br />Microdata<br />a proposed set of structures within HTML5<br />to associate name value pairs with scoped items in HTML<br />© 2011 IPTC (www.iptc.org) All rights reserved<br />4<br />
  10. 10. rNews<br />Launch of rNews<br />rNews 0.1 approved by IPTC in March 2011<br />http://dev.iptc.org/rNews <- Public documentation<br />http://dev.iptc.org/Forum-1 <- Public discussion and feedback<br />IPTC members and invited experts phone calls and semweb-dev<br />Followed by a busy experimental phase<br />Feedback via twitter, blog posts, forum postings<br />Some experimental implementations have been created<br />New York SemWebmeetup in April introduced IPTC and rNews<br />Direct outreach to publishers and potential consumers<br />Incorporated many of the proposed changes into rNews 0.5<br />Some issues frequently raised but no changes so far<br />© 2011 IPTC (www.iptc.org) All rights reserved<br />5<br />
  11. 11. rNews 0.1 -> 0.5<br />© 2011 IPTC (www.iptc.org) All rights reserved<br />6<br />rNews 0.5<br />rNews 0.1<br />
  12. 12. rNews Changes 0.1 -> 0.5<br />Key clarifications, simplifications and expansions<br />Rename “Tag” to Concept<br />Name more accurately conveys the intended meaning and use<br />Fewer classes<br />Former Hed class folded into properties of NewsItem<br />Former TickerSymbol class folded into property of Organization<br />More expressive<br />Adopted the entire georss model, not just lat long for Location<br />Added publishing principles, for parity with hNews<br />Various errata fixed and best practices documented<br />Based on testing rNews 0.1 markup on actual content<br />© 2010 IPTC (www.iptc.org) All rights reserved<br />7<br />
  13. 13. Other rNews Feedback<br />Unified namespace for rNews or multiple?<br />Perhaps the most frequently asked question<br />Is a suggested mapping to “other” namespaces sufficient?<br />Feed back on practical issues with markup<br />Property pairs (literal *and* URI) are confusing<br />Problems with RDFa 1.0 CURIEs<br />Inline markup or Facebook style head metadata?<br />Not just microformats, RDFa 1.0: JSON, microdata, RDFa 1.1<br />Ideally, markup for rNews needs to strike a balance<br />Easy to apply, without radical changes to existing HTML pages<br />Easy to consume, without complex parsing tool chains<br />© 2011 IPTC (www.iptc.org) All rights reserved<br />8<br />
  14. 14. rNews In the News<br />Significant marketing outreach for experimental phase<br />Meetups, blog posts, tweets, video, meetings, phone calls…<br />rNews was certainly noticed<br />Several blog posts, articles<br />Lots of helpful feedback<br />Some interest in implementation<br />Some interest in joining IPTC<br />Reportedly rNews a hot topic at SemTech 2011 in San Francisco<br />http://dev.iptc.org/rNews-in-the-news<br />I believe we did fairly well in responding to feedback<br />More frequent releases would help us demonstrate that<br />Help pave the way to rNews 1.0<br />© 2010 IPTC (www.iptc.org) All rights reserved<br />9<br />
  15. 15. Motion for a Vote<br />Motion to the Standards Committee:<br />To approve rNews Draft 0.5 as a Public Release<br />as specified in 20110518-DRAFT-rNews_0.5.zip<br />© 2010 IPTC (www.iptc.org) All rights reserved<br />10<br />
  16. 16. Motion for a Vote<br />Motion to the Standards Committee:<br />Releases of rNews up to but not including 1.0 will be agreed within the working group, as needed, and made public.<br />© 2010 IPTC (www.iptc.org) All rights reserved<br />11<br />
  17. 17. Discussion of Next Steps<br />Next draft / final draft<br />On track for rNews 1.0 vote at the Autumn IPTC Meeting<br />Publish mappings to other standards, markup models<br />Continue outreach for feedback and experimentation<br />Relationships with W3C, schema.org, others…<br />rNewsMeetups<br />Tuesday, June 7, 2011 6:00 PMAxel Springer AG<br />Axel-Springer-Strasse 65, 10888 Berlin<br />http://www.meetup.com/The-Berlin-Semantic-Web-Meetup-Group/events/17553116/<br />Monday, June 13, 20116:30 PM Press Association<br />292 Vauxhall Bridge Road, London, SW1V 1AE<br />http://meetuplondon.hackshackers.com/events/19792711/?eventId=19792711<br />© 2010 IPTC (www.iptc.org) All rights reserved<br />12<br />
