Semantic Web

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).

Getty AAT goes LOD

A couple of weeks ago, a much anticipated launch finally took place: The Getty Arts and Architecture Thesaurus is now available as Linked Open Data to the joy of much of the cultural heritage community. This was a major step for the Getty Vocabularies programme which so far allowed access to its data through its website or through a paid subscription API.

RDF mapping to multi-valued fields and biblio fields

Hi,

I am creating an academic website with RDF mappings for the content. I am using Drupal 7, RDF 7.x-2.0-alpha4 and Biblio 7.x-1.0-rc5. I have couple of questions.

1) In the RDF UI Mappings for the content types from biblio module, there is no facility to map the fields already present in the content type. RDF Mappings only show up for the newly created fields. Is there a way to do this for existing fields of biblio content types?

Trying out a new tool for surfacing good ideas

It's been a pet peeve of mine for a long time that, while D.O and G.D.O have a lot of great ways to add ideas and discuss them there's really no efficient way of collectively prioritizing the ones we should focus our efforts on.

I have spent a lot of time trying out different tools that do this, as well as trying to design and build them. We may at some point reach a home-grown solution, but in the meantime I have found a very simple and effective tool that I'm trying out. It's called Tricider. I've posted an initial question here:

Drupal 7 LOD appliance for educational purposes

For the "Linked Data Publication with Drupal" workshop (slides) at SWIB13 I've created an appliance for Virtual Box, VMware etc., based on TurnKey Linux. Perhaps it is useful to others with similar plans - see https://github.com/jneubert/tkldev-drupal7-lod-swib13.

Drupal for Linked Data (beating the drums ...)

At ZBW German National Library of Economics we do some work with Linked Data and Drupal. In particular, we recently relaunched ZBW Labs, a web site which showcases prototypes and beta applications. A poster for the Dublin Core Conference (Lisbon, September 2013) "ZBW Labs: Publish Projects as Linked Data" illustrates some lessons learned. A more in-depth talk covers the use of Drupal for "Linked Data Enhanced Publishing for Special Collections" (ELAG Conference, Ghent, May 2013). And at SWIB13 (Semantic Web in Libraries, Hamburg, November 2013), there will be a half-days workshop on Linked Data Publication with Drupal.

Join the Twig Sprint on Friday at DrupalCon Portland

For Drupal 8 we're planning to split the RDF module into two decoupled modules:

  • The RDF module will only care about defining the mappings with the entity types and the fields, without dealing with any syntax/presentation. Thus it won't do much on its own, but other modules can rely on it to output data.

  • The RDFa pieces of the existing D7 RDF module will be moved into a new module that relies on the RDF module to get the term mappings and constructs the RDFa markup from these mappings.

Importing Facebook groups wholesale into Drupal Organic Groups?

I'm wondering if anyone has done any work on importing Facebook groups wholesale into Drupal Organic Groups? I know we can export all the data from a Facebook group using the Facebook API. I guess the main task is to how to map Facebook comments (with revisions?), users, events and pages to a local Drupal instance. I guess make placeholders for these Facebook objects and allow these to be acquired retrospectively? Any ideas? Any projects with similar aims?

Integration with the ALICE chat bot.

I would like to initiate a project where the A.L.I.C.E. chat bot reads RDF from a site and uses it to respond to queries. The A.L.I.C.E. people (alicebot.org) are on board and have already linked their bot with RDF but we need some people who are knowledgeable with RDF in Drupal to make this happen.

I intend to start a Kickstarter campaign to fund this project.

Please let me know if you are interested in an initial conference call to discuss the parameters and to come up with a budget.

Does Drupal's RDF implementation support Graph databases?

I hope this isn't a dumb question, but do the drupal RDF* modules support having a separate RDF database like Neo4j or others?
It seems that any full-scale semantic application implemented with Drupal will very quickly grind to a halt if the data is stored in an RDBMS.
If there's been any discussion, drupalcon talks, or similar on this subject, I'd be very interested to click on that.

Alternative RDF models for Drupal

RDF support in Drupal has been implemented with this model in mind:
Node = RDF subject
Field = RDF predicate
Field value = RDF object

This is a wonderful solution for most of Drupal content where the content type is ontologically connected to the field by a predicate.
