rNews - towards structured data websites

Out of your silo! ...with rNewsRune Smistad, MediArena, Media 3.0, 11. mai 2011 Inspired by Evan Sandhaus, Lead Architect, Semantic Platforms, The New York Times Company. http://slidesha.re/jd8uLM

Content read in own context

Tomorrow

Content read in other context

More precisely:• aggregation / enrichment• syndication• IPR• capitalization

Content need to be data Presentation and sharing must behandled by metadata

One possible solution• rNews (...and datagartneriet)

rNews• rNews is NOT a software• rNews is a linked data standard developed by IPTC, with direct support for their other metadata standards. It open for your additions and deﬁnitions.

RDFa - ResourceDescription Framework• In theory RDF is a ﬂexible extensible format for expressing and sharing knowledge.• Problem with the theory - The Web shares “knowledge” using HTML.• Solution: RDFa - a W3C standard for embedding RDF triples within standard HTML documents. + <HTML/> = RDFa

<HTML+RDFa/> RDFa distiller

Roadmap to the future:1. Implement rNews standard and show content as RDFa (and let datamarket.com search your events)2. Use external, shared metadata3. Business model where IPR is handled by metadata New context for your content and enrichment of your own context.

LOD star scheme reference

What can we do?• We are building a technological infrastructure in Bergen for shared metadata/vocabularies and entrance to the Linked Data cloud.• rNews use IPTC - we already have the IPTC standard in our RDF store, with possibilites for editing, sharing.

What can you do?• Look through the IPTC/rNEWS standard http://dev.iptc.org/rnews• Visit medialab.datagartneriet.no (monday)• Contact us at MediArena: • rune@mediarena.no, anders@mediarena.no• Follow us • @bergenmediarena • #mediefremtid

One more thing...

We establish adeveloper forum in Bergen today Tonight, 18-20, at The Hub
