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).

Rich snippets (micro formats, micro data and RDF)

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.
What is drupal view on this?

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

Thanks a lot

VARQL, 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).

Best 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!

Importing lots of nodes from DBpedia -OR- Import under request

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:

  ?book rdf:type dbpedia-owl:Book;
    dbpedia-owl:abstract ?abstract;
    dbpedia-owl:author ?author;
    rdfs:label ?book_name.
  FILTER (lang(?abstract) = "en")
ORDER BY ?book_name

Big News - Google officially announces support for Good Relations RDFa markup

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.

RDF right way to fetch wikipedia?


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?

Getting started moving D6 site into the semantic web

Please forgive the trivial nature of this question. I've been doing some background reading but not quite sure exactly where to begin.

I have a currently functioning Drupal 6 site. It works great with Views, CCK, and a few other modules. I want to add RDFa tags so content on my site can be found (and linked) from semantic web search engines. It seems like I would need to add three modules:

New York Times and the Semantic Web

This really is not much of a deceleration.

The New York Times now uses Open Graph as a doc type.

I can't imagine getting editors of an online newspaper to submit this much data as outlined in the New York Times Annotated Corpus Overview.

RDF gatherings at DrupalCon Copenhagen

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.

A DITA documentation distribution for Drupal


A couple of weeks ago we launched Modulecraft an awareness & fund-raising project that aims to rally Drupal professionals around a shared effort to create the ultimate toolset for Drupal business. The first fundraising round has as goal the development of a documentation distribution for Drupal that uses a similar approach as the localization server and that enables a distributed/federated documentation architecture for the Drupal project. As a Drupal user you'll be able to get a set of documentation from the docs server imported into your own site. You will than be able to edit it and build subsets of the documentation for your own projects. You'll also be able to submit topics that were edited or created by you on your own infrastructure and add them as suggestions to the Drupal documentation server.

The following is a first proposal for the specification of the Documentation system we want to build as part of the modulecraft project. It is by no means complete, and it strongly needs your feedback. This is our first encounter with DITA and our ideas should really be proof checked by technical writers that have extensive experience using DITA. It also contains some proposes a somewhat exotic usage of RDFa, feedback is also very much needed here. In the coming days I'll be adding new sections to the specification here. This is a wiki so be bold! You can add comments either here or at the original posts on the Pronovix blog. I'll be incorporating feedback into this wiki.
