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).
Linked Data and RDF events at DrupalCon Austin
Are you attending DrupalCon Austin and looking to learn more about Linked Data and Drupal? Here are a few events you shouldn't miss...
Read moreGSoC Project : Schema.org Mapping Tool
I’m Sachini Herath, following my bachelors degree in Computer Science and Engineering at University of Moratuwa, Sri Lanka. Currently pursuing my third year of study, I have worked on some projects using PHP and Symphony framework (You can find the source codes in github). I’m delighted to contribute to Drupal as my Google Summer of Code project this year.
Read moreGetty 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.
Read moreRDF code sprint next Tue before the Boston meetup
This is a cross Boston + Semantic Web groups event to announce a small code sprint on Tuesday right before the Boston Drupal meetup. We will sit on the lower ground of the main entrance of the Building E51 - Tang Center. I'll be there at 4pm. Remotes are welcome to join as well, ping scor on IRC #drupal-rdf and we will coordinate from there.
Read moreRDF 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?
Read moreRDF code sprint this Saturday during the Drupal Global Sprint Weekend
As part of the Drupal Global Sprint Weekend in Boston, we will host an RDF code sprint this Saturday. Anyone can join us in Boston at the Genuine Interactive office, and remote sprinters are also welcome to join on IRC and Google Hangout. Just find me (scor) on IRC in #drupal or #drupal-rdf in order to get you started.
Read moreTrying 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:

Read moreDrupal 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.

We are excited to let you know about the high level hands-on workshop on Drupal Content Management System - organized by the the IEEE Kerala GOLD along with the FOSS Young Professional Meet 2013 on September 27,28 and 29 at Technopark Trivandrum.. This will be the 9th such training by Chennai Drupal Community! Our last one was at KGISL and KITE Engineering College, Coimbatore.
Read moreRDF in Core office hours on Monday mornings
I'm making myself available to help anyone interested in contributing to RDF in Drupal 8 every Monday morning between 8am and 10am EDT. Kay VanValkenburgh and Jesse Day have already expressed interest in participating. Come join the group on IRC #drupal-rdf (some of us are there the rest of the time too). We will use this pad during the sprint to keep people aware of what others are working on. See other related posts:

This wiki page represents the current state of the schema.org support for Drupal 8. Every attempt will be made to keep this document as up to date as possible.
Read moreJoin 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?
Read moreIntegration 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.

Read moreDoes 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.
Recommendation for linking to external RDF data
RDFx allows for fields to be expressed as RDFa. Sometimes RDF concepts exist in other locations, for example DBpedia, and not as part of the local taxonomies. What is the recommended way to link to these external resources? These resources do have persistent URIs, so I guess the simplest thing to do is to make the field into a link. But ideally one would prefer to get a good label to show on the HTML output rather than the link itself. RDF Proxy (http://drupal.org/project/rdfproxy) seems to be doing that but the project appears to be abandoned. Any ideas?
Read moreCallimachus integration with Drupal
Hi,
the Version 1.0 of Callimachus project has been released.
http://callimachusproject.org/index.xhtml?view
Would be possible to integrate Callimachus with Drupal,so as to easily make open data/linked data applications?
thanks
