Semantic Web

This group should probably have more organizers. See documentation on this recommendation.

Welcome to the Semantic Web group in Drupal. This group was started at DrupalCon Barcelona 2007 and includes discussions on how to integrate the Semantic Web technologies into Drupal and list the various effort of the community towards enabling RDF in Drupal. Drupal 7 comes with native RDFa support in core. If you want extra RDF capabilities such as other serialization formats and SPARQL support, checkout the RDF Extensions, SPARQL and SPARQL Views contributed projects. If you need support or have found a bug in one of the fore mentioned projects, please file a ticket in their issue tracker (block on the right on each project page).

How do you prepare for RDFa features in Drupal 7?

Posted by bdubb on March 11, 2009 at 9:12pm

If I am creating a new site on Drupal 6, how can I better prepare my content for the RDFa features being developed for Drupal 7?

DrupalCon DC 2009 - RDF sessions braindump

Posted by scor on March 10, 2009 at 5:10pm

DrupalCon DC 2009 featured a nice selection of RDF related sessions. 2 regular presentations served as introduction to those who were unfamiliar with the topic, or just wanted to refresh their mind with the latest happenings.

Tokens & RDF in d7 - can they benefit from each other?

Posted by fago on March 7, 2009 at 3:58pm

Right now there is a issue for getting token into core and one for getting some RDF into it. I wonder if makes sense to base the token patch upon the RDF stuff. So once we have some semantics attached to our objects, we can use them as a starting point for doing the token replacements.

The other way round, the RDF patch could learn from the tokens code - as the actual problem to solve is quite similar. The way the patch in #74 uses simple handlers to get tokens would make sense for RDF too. Then the token implementation can go and build upon that and reuse the handlers returning RDF string literals. Similarly, the approach described in #77 for doing actual token replacements could also be used for getting chunks of RDF for a bunch of objects.

Then apart from avoiding inventing the wheel twice, we could easily make both APIs consistent, so they can be used the same way.

As agreed during the BoF session feel free to add your name, the organization you work for and a few lines about your interests and use case of RDF. You're also welcome to add your name here even if you were not physically present at DrupalCon DC!

Poll on Semantic web code sprint

Posted by kvantomme on February 24, 2009 at 12:52pm

I've put together a Surveymonkey poll to make it easier to work out the exact nature of the meetup Stephane announced. If you are interested in this event, please take a minute to indicate your preferences.

Since I don't have a paying account I can't share the results out of the box, but I'll post a pdf report as a follow up.

Update: Sprint scheduled!

DERI Galway would like to host an RDF in Drupal code sprint sometime in May. More and more people are considering using Drupal for their RDF project, so let's get our ideas together and see what can be done to make the semantic web integration in Drupal easier. Please feel free to add your ideas, suggestions, comments, critics.

SKOS Integration to Drupal

Posted by rcelebi on February 16, 2009 at 6:30am

Hi all,
I am a researcher from DFKI in Germany and we (under leading of Leo Sauermann) are currently working on a project called OrganiK which aims to research and develop a semantic web 2.0 (social, semantic, 2.0) knowledge management system for SMEs.

Any easy tutorials for Beginners?

Posted by nishant.in on February 8, 2009 at 11:49pm

Hi everybody,

Before I go ahead, let me apologize for being a new comer to the world of semantic web and drupal .. may be some of you might find it funny .. but I have spent the last few hours installing the Drupal Modules relations-6.x-1.0-alpha5 , rdf-6.x-1.0-alpha5 , sparql-6.x-1.0-alpha1 and exhibit-6.x-1.0-alpha2 and reading about semantic web , I have understood the subject - predicate - Object logic .. have designed the RDF logic on paper , created two node types in Drupal ... however I am struggling to establish the relation between them in Drupal.

Field of applications with RDF, Sparql & Co?

Posted by derhasi on February 5, 2009 at 5:21pm

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

where can I find a RDF/XML output

Posted by aydos on January 20, 2009 at 7:52am

Hi everyone,
I need to show a web page with RDF for my semantic web course... I use RDF (api) module (development version for mappings).
I set up CCK field to map with an ontology and build a page containing this field...
So far it is ok... But, where can I find a RDF/XML output???

Identifying a resource in RDF

Posted by rszrama on January 12, 2009 at 8:16pm

I fear I'm grossly misunderstanding core RDF concepts, so I'll just ask a single question and see if there's an actual answer or just better informed questions... : )

Is there an established practice for generating a unique ID for something, like a particular news article that might be syndicated by other sites or a product for sale that might be listed in external shopping/review directories?

Content Discovery

Posted by toursheet on December 13, 2008 at 7:28am

Is there a module that achieves personalized recommendations of community content from a users tags against all other users content tags?

So if user A tags a community node with 'drinks', 'entertainment', and 'bar' the resulting recommendation block would push similar tagged content to user A.

I've been reviewing the following modules but still confused

http://drupal.org/project/recommendation

setup for a subscribed friend to friend recommendation???

http://drupal.org/project/cre

only recommends content that has been voted on via VotingAPI.

VoCamp Galway 2008

Posted by scor on November 17, 2008 at 6:31pm

Start:

2008-11-25 09:00 - 2008-11-26 17:00 Europe/Dublin

Event type:

User group meeting

DERI Galway will host the second VoCamp next week. VoCamp is a series of informal events where people can spend some dedicated time creating lightweight vocabularies/ontologies for the Semantic Web/Web of Data. The emphasis of the events is not on creating the perfect ontology in a particular domain, but on creating vocabularies that are good enough for people to start using for publishing data on the Web.

A roadmap for RDFa in Drupal 7

Posted by scor on November 8, 2008 at 6:06pm

RDFa into Drupal 7 core is on its way! It is now time to start implementing it. We need to agree on a roadmap to help ensure we all head in the same direction before rushing to our keyboards and posting patches on drupal.org. I met up with John and Alexandre from the SIOC project and we came up with the following approach.

What is RDFa?

Using FCKeditor for RDF?

Posted by chrisschaub on November 6, 2008 at 9:30pm

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 ...

...
        <Style name="RDF Author" element="span">
                <Attribute name="property" value="dc:creator" />
        </Style>
...

How to mark up Drupal's update status feed with better RDF?

Posted by robertDouglass on September 19, 2008 at 4:08pm

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?

Here's a snippet:
