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).
Boost OpenPublic in Europe + 28th of April deadline to apply for FP7-ICT-2011-SME-DCL
After Drupal Gov Days in Bruxelles there has been no follow up that I know after the presentation of Stephano Bertolo (slides attached). Stephano knows a lot about Drupal. He gave the example of OpenPublic (slides 25) and on slides 28, he told us that there was a budget of 35 M Eur budget to help ““Small and Medium Enterprises building pools of data, content, language resources to maximise reuse” (FP7-ICT-2011-SME-DCL)
I may be mistaken but I think the Drupal Community could fit into that :
-We could list all projects of translation of OpenPublic and what it would take to coordinate
Question about semantics in Drupal
Hello,
I want to create a website which use Semantic web technologies.
So I want to know how semantics is implemented in Drupal to get some ideas. Here some questions :
- I will use RDFa to annotate my pages, can I access them using ARC2 RDFa parser even the pages are with .php extension, or I have to redirect pages using Apache redirection rules to change the extension to .html ?
RDFme: a RDF drupal module
Hi,
I've been developing a RDF module for Drupal. It was a part of my final thesis/project, and was created due to the lack of flexibility of the "RDF" module in Drupal 6.x. The module got the interest of some universities, national projects, etc and I would like to share it with the community.
I'm currently applying for a "full project access" and it would be nice to get some reviews. it's my first Drupal module and I'm sure that there will be some bugs or I didn't follow ALL the drupal code standards.
Suggestions needed on my GSoC idea
Hi
I am willing to contribute to Drupal-7 in GSoC-11 as a Student. I would like to Extend the functionality of the contributed RDF Module in Drupal-7. I have posted a detailed description of my idea here :
http://groups.drupal.org/node/136969
I would be grateful if you could please go through it and provide me feedback on my idea so that I can further improve it. Also, I would need someone to mentor me in this project. So please let me know if anyone is interested to mentor this project.
Thank you.

Use of specifying rdfs:range Constraint in RDF Schema ?
I am Mayank, Final year undergraduate student at DA-IICT, India. Since I am relatively new to Drupal-7 RDF, I would really appreciate if you could help me out here.
I have created a custom content type for my project purpose. The RDF Schema for the vocacbulary seems to have registered properly with Drupal and in the Database Tables. However, the issue that I am facing is that the value constraints that I have set within the Schema are not having any effect on the RDF that is generated.
Read moreDrupal and FOAF vocabularies
Hello,
I was interested in creating FOAF files or profiles for users of my site(s) that use Drupal. I would like advice and suggestions on the types of modules I would need to make this happen. I am assuming one is the RDF module. I guess I would need the external vocabulary importer.
1) What other modules might be needed?
2) What would be needed to have drupal save a foaf.rdf file when a person enters their information into the forms? Would this be how one might do this, have drupal create or update a foaf.rdf file when a user enters information of content type FOAF?
Importing and manipulating the (semantic) data in Drupal
Dear members of the Semantic Web & Views development,
I have been playing with the idea of using Drupal as rapid development environment for (semantic) web applications, rather than CMS. The idea is not as far-fetched as it may seem at first:
-
CCK allows me to define a database model. Core functionality in D7.
Feeds parser lets me to pre-fill the data in nodes defined in step 1 - including the possibility to fetch data at regular intervals, update nodes and drop old nodes.
RDF-related functionality allows me to associate the data saved in pre-defined nodes with ontology terms.
Views allow mixing of data from different node types
It is also possible to programatically define data (e.g. automatically fill in a field) both in the node and in the View
Finally, there are plenty of modules that let me do just about anything with the data once I have it in nodes & views. Some exampels include e.g. visualization on a map, and setting up a web server (SOAP, REST, ...) that exposes my data to the outside world.
Using external reasoner with Drupal
I'm trying to use an external reasoner, Jena, with Drupal for my project.
I have node class definitions and their CCK fields exported as RDF. I was wondering how
to access the RDFs at node/*/rdf from Jena.
Can anyone please help me in understanding where the RDF is stored?
Thank you for any help.

Read moreRDF CKK Error : Help needed
Hi,
I'm trying to build a website similar to ( http://www.lin-clark.com/rdf-faculty-db/).
I installed all the modules and created a new content type using RDF CCK content fields called Person(class foaf:person).
But, when I inspected the elements on any person node, it does not have any RDF/RDFa tags. The node/*/rdf gives a " XML Parsing Error: junk after document element" error.
I'm unable to figure where I might have gone wrong.
I'm pretty new to Drupal and RDF, I'm sorry if this is a very direct question. But, I'm stuck and any help will be greatly appreciated.

Hi all,
I am wondering if someone could help me understand the benefits pros and cons of the different ways to markup the content.
Specifically I am thinking about microformats, micro data and RDF.

I hope that someone can point me in the right direction.
Thanks a lot

Read moreVARQL, a Views SPARQL Query Plugin
Hi, yesterday I've released VARQL (SPARQL Views Query Backend), the module is intended to help in generating SPARQL queries using our Views lovely and intuitive UI.
VARQL utilizes Drupal 7 built-in rdf mapping in building SPARQL queries; for example if you want to select a couple of recored from DBedia, namely, name and homepage, varql will map these fields to foaf:name and foaf:homepage respectively to build a query
Any reviews or feedback would be greatly appreciated (especially regarding RDF mapping and views query plugin).
Read moreBest modules for enabling triple tags
Hi there! New to Drupal. I need help.
What module(s) or resources are best to help me enable triple tags, where:
1. Each tag is composed of a subject, predicate, and object.
2. The subject, predicate, and object can be chosen from specific nodes on my site. Each field can suggest nodes as you type.
3. Two nodes with the same name can be differentiated by an ID or something.
My goal is to link my nodes into a linked graph that can be queried by something like views. I want to display the relationships between nodes.
Thanks for your help!

Hi mates!
After importing people from Pittsburgh to my Drupal site (thanks linclark), I'm currently trying to do the following in order to develop a project. I need my site to show info about any book my users may ask for.
First tried to import only resource name, abstract, label and author:
SELECT * WHERE {
?book rdf:type dbpedia-owl:Book;
dbpedia-owl:abstract ?abstract;
dbpedia-owl:author ?author;
rdfs:label ?book_name.
FILTER (lang(?abstract) = "en")
}

This news came a few days ago... Google is officially supporting the Good Relations (e-commerce) ontology as a source for Rich Snippets.
This means that once we have a good mapping for it in Drupal Commerce, sites that use Drupal for commerce will be at a distinct advantage. Yahoo research showed that click through rates for rich snippety search results were 15% higher, and other research has shown up to 30% higher.
Read moreRDF right way to fetch wikipedia?
Hi,
before I start with RDF, one question:
I'm searching a way to use short teasers and images of wikipedia articles on my website. I would like to have a small block, where people get a short information around the topic sailing. About different sailing boats, about sails.....
I would like to fetch the image url, and the first maybe 300 words of the article.
Am I right to start with RDF for this or should I use another way?
Best
Joerg
