Today at DrupalCon Copenhagen, we've had the biggest gathering of RDF enthusiasts at the two Birds of a Feather we had during the day. I don't have the exact number but I think we had about 40 people combined. The main RDF session on Thursday was a big hit as well and lots of newbies who never heard of RDFa until it was put into Drupal 7 joined us.
In some of the sessions, Lin and I were asked some links so here it is, inspired from a list of links Arto posted a while ago:
- Intro to the Semantic Web (6 mins)
- RDF Quick Intro(article; reading time ~10 minutes)
- RDF in Depth (article; reading time ~1 hour)
- RDF Introduction (slideshow)
- The Semantic Web by Tim Berners-Lee et al. (article; reading time ~20 minutes)
- How to Tell Stuff to a Computer (set of articles)
- SEMANTIC WEB for the WORKING ONTOLOGIST (book)
We had a very good round of use cases going around the table, especially at 4pm. Feel free to leave a comment below if you want to keep the conversation going, or if you missed something, just ask. And if you are not subscribed to this group yet, please do so you can stay tuned.
The demo Lin and I showed today are still under going development, but for those who want to get their hands dirty or contribute:
- Main RDF in contrib modules for Drupal 7
- SPARQL Views
- RDFDB

AWESOME! with these modules
AWESOME! with these modules drupal could be considered as a RDF framework :D
Awesome indeed!
These modules are very useful! Thanks everyone for making them!
With nodes & node references, Drupal seems a very neat fit to RDF and links between data objects, making this a very natural way forward for both Drupal and the Semantic Web!
Criteria for including vocabularies
During the 4pm BOF we were had several proposals for additional vocabularies to be included in Drupal 7. One thing we did not touch on was how we evaluate when a vocabulary belongs in core and when it would be more suitable for import. Personaly I would like to see dcat and voiD as a part of core and I had a feeling that this was supported by Stephane and Lin so all should be well but I still feel that we need an objective criteria for choosing new vocabularies.
Thoughts?

how we evaluate when a
The criteria for core is simply whether a vocabulary is used in the default mappings or not. When you say "core", I'm assuming you are talking about Drupal core. The contrib RDF module can also import some vocabularies upon installation (via evoc), though the list of automatically imported module is not yet defined. We should probably import the usual suspects like FOAF, SIOC, DC like we were doing in Drupal 6.
Drupal core is frozen and it's too late to add these to core. I would rather see them in a specialized module which would not only import them, but also annotate the right bits of data with these, making the job of the site admin as easy as possible (module, feature or install profile).
OK. My mistake. I should have
OK. My mistake. I should have talked about automatically imported module and not core. (Drupal is still new to me) I agree that dcat would be a candidate for specialized modules but why should voiD not be on the list of automatically imported vocabularies? Was the reason for choosing FOAF, SKOS, SIOC and DC only based on the fact that these vocabularies are the most popular or are there other criterias - criterias that can be used as a general rule for future candidates?
Oh Snap! SEMANTIC WEB for the
Oh Snap! SEMANTIC WEB for the WORKING ONTOLOGIST looks good. I added it to the handbook page http://drupal.org/node/219862.
@scor
zzolo just gave the Location and Mapping group's page a face lift. I would be happy to do the same for the Semantic Web group if you don't have the time. I think this group will be getting more attention with the release of Drupal 7 drawing near and it would be nice to have documentation links on the landing page for people looking to get started.
feel free to work on the RDF
feel free to work on the RDF docs and move things around as you see fit. They do need a face lift!
good idea :) SemWeb for the
good idea :) SemWeb for the Working Ontologist is really good. I've also been meaning to check out Programming the Semantic Web, just downloaded chapter one, so if that is good I'll add that too.
