IPTC SemWeb Working Group

• Making use of Semantic Web technologies for news– Leverage technologies developed by others

• The work falls into two main areas:– Models

• Determine what aspects of news to represent– Formats

• The details of how to represent the news• Using RDFa, microformats, Linked Data, microdata

IPTC’s Semantic Web Agenda

At this meeting we will discuss

• The rNews 0.5 model• News Metadata in HTML Markup

• RDFa• Microformats• Microdata

• For vote: rNews Draft 0.5


News Metadata in HTML• One goal

– Promote the creation of better, more accurate tools for working with news on the web

– By adding news metadata to HTML

• (At least) three approaches– Microformats

• conventions for using standard HTML• to add labels to indicate the meaning of markup

– RDFa• alter your HTML document to use non HTML attributes• to insert RDF triples to indicate the meaning of markup

– Microdata• a proposed set of structures within HTML5• to associate name value pairs with scoped items in HTML


rNews

• Launch of rNews– rNews 0.1 approved by IPTC in March 2011– http://dev.iptc.org/rNews <- Public documentation– http://dev.iptc.org/Forum-1 <- Public discussion and feedback– IPTC members and invited experts phone calls and semweb-dev

• Followed by a busy experimental phase– Feedback via twitter, blog posts, forum postings– Some experimental implementations have been created– New York SemWeb meetup in April introduced IPTC and rNews– Direct outreach to publishers and potential consumers– Incorporated many of the proposed changes into rNews 0.5– Some issues frequently raised but no changes so far

rNews 0.1 -> 0.5


rNews 0.1 rNews 0.5

rNews Changes 0.1 -> 0.5

Key clarifications, simplifications and expansions• Rename “Tag” to Concept

– Name more accurately conveys the intended meaning and use

• Fewer classes– Former Hed class folded into properties of NewsItem– Former TickerSymbol class folded into property of Organization

• More expressive– Adopted the entire georss model, not just lat long for Location– Added publishing principles, for parity with hNews

• Various errata fixed and best practices documented– Based on testing rNews 0.1 markup on actual content


Other rNews Feedback

• Unified namespace for rNews or multiple?– Perhaps the most frequently asked question– Is a suggested mapping to “other” namespaces sufficient?

• Feed back on practical issues with markup– Property pairs (literal *and* URI) are confusing– Problems with RDFa 1.0 CURIEs– Inline markup or Facebook style head metadata?– Not just microformats, RDFa 1.0: JSON, microdata, RDFa 1.1

• Ideally, markup for rNews needs to strike a balance– Easy to apply, without radical changes to existing HTML pages– Easy to consume, without complex parsing tool chains


rNews In the News

• Significant marketing outreach for experimental phase– Meetups, blog posts, tweets, video, meetings, phone calls…

• rNews was certainly noticed– Several blog posts, articles– Lots of helpful feedback– Some interest in implementation– Some interest in joining IPTC– Reportedly rNews a hot topic at SemTech 2011 in San Francisco– http://dev.iptc.org/rNews-in-the-news

• I believe we did fairly well in responding to feedback– More frequent releases would help us demonstrate that– Help pave the way to rNews 1.0

Motion for a Vote

Motion to the Standards Committee:

To approve rNews Draft 0.5 as a Public Release

as specified in 20110518-DRAFT-rNews_0.5.zip


Motion for a Vote

Motion to the Standards Committee:

Releases of rNews up to but not including 1.0 will be agreed within the working group, as needed, and made

public.


Discussion of Next Steps

• Next draft / final draft– On track for rNews 1.0 vote at the Autumn IPTC Meeting

• Publish mappings to other standards, markup models• Continue outreach for feedback and experimentation• Relationships with W3C, schema.org, others…
