RDF

FOAF, DC, SIOC, SKOS are famous vocabularies commonly used in the Semantic Web. Many other custom vocabularies exist and are created everyday. Vocabularies play an important role in the Semantic Web as they enable interoperability across various RDF data sources, and are used by RDF publisher and consumers who refer to them in their data.

I would like to take an opportunity and introduce yet another file framework for Drupal 6. The project page is http://drupal.org/project/fileframework.

Hi All,

I have recently been looking into drupal's intiative around semantic web. I also looked around the modules contributed in rdf and the api's associated with it.

Regarding it, i would like to open a discussion around using 3rd party triples stores to integrate with drupal and rdf api's available. Right now the triples are stored in RDBMS lets say mysql but looking at this approch, i doubt on the scalibility factor for it. A case when lets say 1 billion triples are there in the store, how the performance will be in that scenario ?

hi,

for a first simple support for RDF export, I'd like to point you to http://blog.aksw.org/2008/triplify-expose-semantics/ and http://triplr.org.
I think a quick generic RDF support for nodes will be easy to add.

I also recommend to keep the current node URI scheme and add support for content negotiation as described in [1]. So, if a client sends the request header "Accept: application/rdf+xml", the server just returns an RDF version of a node, otherwise it will get the ordinary HTML version, possible polished up with RDFa or microformat tags...

Regards,
Andy

Summary:
I want to write two modules for Drupal as part of Google Summer of Code. One called meme_tracker and the other called machine_learning_api. The meme_tracker module will use the machine_learning_api to intelligently filter and group content from both internal and external content sources. The module's purpose is to find and display to a community in real time the most interesting conversations and memes within the community as they emerge.

Hello Drupliers. My name is Kyle Mathews. I'm a grad student in Information Systems at Brigham Young University working as a research assistant to several faculty members here. We are studying how and where social software can be used in education.

In the past eight months, I've built a number of classroom websites using Drupal. I've learned a considerable bit about Drupal in the process, became very involved in the community, and am writing a module (writing_assignment -- still a work in progress btw). I've loved most everything about Drupal but have found Drupal is missing an important component for building the perfect social learning website. This itches. So, in the best open-source fashion, I'm applying to Google Summer of Code to scratch my itch.

Today I talked with Thomas Hochhaltinger from ebSemantics, a project of "Smart Information Systems", an Austrian company that developed MyOntology.org a collaborative ontology designing platform with ontologies for consumer electronics goods.

Reuters released a web service called Open Calais. It is built on clear forest technology that has been around for a while.

You can throw text at it and get tags organized by country, personalities, industry terms, ... in RDF format back. It is of better accuracy than http://tagger.flaptor.com/findtags, http://tagthe.net or yahoo terms extraction API (http://www.programmableweb.com/api/yahoo-term-extraction, http://drupal.org/project/yahoo_terms)

You can try it here:

KarenS has kicked off a discussion on CCK field structure for core in D7. It's also webchick's itch of the week.

David Strauss is already commenting, and has experience in RDF from the Internet Archive, but it would be good to have other experienced people giving this the once over. Since these fields are likely to be a major way that people "transparently" create subject/predicate/object relationships, we better get this right (and performant, working on shared hosts, etc. etc.).

In regards to the Semantic Web developments announced recently about Drupal 7, I have posted a blog entry at SitePoint and also posted to the Linking Open Data mail list.
