RDF

Reading into the area of semantic web applications, rdf, owl, etc. let me wonder about the lack of information you can get of the current state of development in this area. There doesn't seem to be a wide range of applications using OWL or even RDF. Therefore I'd like to know, what range you use rdf, owl & co for? Especially, how do you/ can imagine to, use Drupal for fürther applications?

My current project

I'm interested in non-programmer tools that are available to help content creators "mark-up" their content for RDF (Resource Description Framework) discovery. We need good tools to describe free-form content that isn't already fielded in a database.

I am a big fan of FCKeditor (http://drupal.org/project/fckeditor), especially because it is so configurable. You can customize the fckstyles.xml file and add a new style like ...

The update status feed that Drupal.org produces is marked up with the Dublin Core namespace. This is, I suppose, a "good thing", but essentially useless information in the absence of anything else more meaningful. How would we represent this information in an ideal world? What can be done with existing schemas and vocabularies?

Drupal

At drupalcon Szeged their was an interesting suggestion to define RDF for Drupal curriculums. Check the presentation.

Their was the suggestion to write down bullets of what need to be in the curriculum. To me however, their it is not yet enough clarity to start creating bullets. I'm looking forward to a discussion. Whatever your point, let this post be an invitation for a discussion.

UPDATE: Cancelled - I don't have time to prepare for this :(

This is a BoF discussion that is planned for August 24, 2008 at 15:15 - 16:30 as a part of the FrOSCon conference in Sankt Augustin, Germany.

This BoF discussion will focus on what semantic web tools are available to Drupal, including:

• The RDF framework: http://drupal.org/project/rdf
• The SPARQL module: http://drupal.org/project/sparql
• Neologism: http://code.google.com/p/neologism/

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.
