GRDDL & RDFA : Weaving Richness and Meaning in the Web

Krista Thomas from Thomson Reuters will start the talk with a brief product intro on OpenCalais. Our main speaker Brian Sletten from Riot Games will talk about GRDDL and RDFa Synopsis below: The human web is reasonably well in hand by now. We are getting pretty good at building systems that people find valuable and entertaining. We have not spent as much time concerned about our software friends. There is a ton a rich content available on the web that is too difficult to extract in automated ways using just XHTML, the meta tag and microformats. This talk will introduce you to some emerging technologies from the Semantic Web camp to enrich your web pages with useful information for both automated extraction and improved browsing experiences. The Resource Description Framework (RDF) is the metadata substrate of the Semantic Web. It allows you to express fairly arbitrary relationships about people, places, things, content in an open world way. It is trivial to mix and match terms, vocabularies, etc. to have a rich expressive capability not bound by the limitations of the relational data model and XML schemas. GRDDL is a technology for generating RDF metadata from content on demand. This can include XML documents, XML-RPC requests, XHTML pages, etc. The content could include authorship information, geotagging, creative commons license information, the topic of the document, etc. RDFa allows us to be more explicit about the metadata by embedding actual RDF relationships in our content. With technologies no more complicated than the presentation markup we are already using, you can imbue any web tier with extra semantic specialsauce that will benefit your users as well as help link you into the emerging Web of data. Speaker: Krista Thomas Krista Thomas leads Marketing & Communications for the Thomson Reuters OpenCalais Initiative. The free OpenCalais Web service and open API is the fastest way to tag the people, places, facts and events in your content. OpenCalais makes it easy to automate content operations, enhance content with open data assets, and increase reader engagement.

    Both presentations, Open Calais and GRDDL/RDFA were presented by experts in their field. The greatly assisted the new semantic web practitioners with a greater understanding through informative discussion.

    Many thanks to Brian Sletten who did an amazing job of breaking it down for us. I learned a lot and an eager to learn more.

    I hear so much about RDF it was great to see what RDFa offers - it looks like a great way of bringing semantics into what's already here sooner for content authors who many not have 4-10 years to dedicate their life into mastering the deeper richness of semantic technology. The RDFa distiller to mulgara (semantic datastore) demonstration impressively shows how one can transform and ingest published content back into a triple store with relative ease.

    We've had some amazing meetups in L.A. in the past year but this was definitely one of the best! Thanks to Krista and Open Calais for providing the venue and some beer and pizza :)

    Hey all - wanted to let you know that we will also have pizza and soda courtesy of Thomson Reuters since we are meeting during the dinner hour. So if you make it by 6, you get the hot pizza. Joe - if you can't make it until 6:15 or 6:30, you'll still get some lukewarm pizza. ;-)
