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).

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!

Specification for our dream (DITA) documentation tool

In February LeeHunter posted his wish list of features for "an awesome technical communication CMS". I've copied his list and processed the comments in the discussion and some of my own, and added our current status implementing these features and ideas of how any missing features could be implemented in the near future.

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:

SELECT * WHERE {
  ?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?

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

Errors after Install of Sparql, and evoc

Whenever I try to import and external RDF library, I get this error:

* warning: Invalid argument supplied for foreach() in /home2/future/public_html/drupal/sites/all/modules/evoc/evoc.module on line 199.
* warning: Invalid argument supplied for foreach() in /home2/future/public_html/drupal/sites/all/modules/evoc/evoc.module on line 199.

Then it tells me the namespace has been created.

Should I worry about this? What does it mean?

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:

RDF
RDF CCK
RDF External Vocabulary Importer

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. http://opengraphprotocol.org/schema/

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. http://www.ldc.upenn.edu/Catalog/docs/LDC2008T19/new_york_times_annotate...

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

Introduction

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 drupal.org 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.

Updating RDF documentation for Drupal 7?

While plugging away at the documentation issue queue I noticed that the RDF documentation (http://drupal.org/handbook/modules/rdf) hasn't been touched for a couple of years so I'm wondering if it needs to be updated in any way for Drupal 7.

I don't know anything about RDF myself, so if someone who's up to speed could look at this it would be really appreciated.

Anyone can edit the Drupal handbooks if they're logged in.

Is D7's default use of the Semantic Web ethical?

Obviously, the title was created was designed to elicit discussion ... but I am seriously interested in the prospects for unintended consequences of D7's default use of RDF. D7 will be a great leap forward, and I'm genuinely excited about the prospects of D7's adoption of RDFa. Upon further reflection, I'm wondering if D7's embrace might actually make it easier for users to be tracked by organizations like Recorded Future. I understand, that today's default settings can be "undone" ... but it is the default that has me most concerned ... precisely because it is the novice end user who isn't particularly savvy that will be put at most risk ... and is unlikely to even know what is going on "under the hood" ... I know, I know ... probably an exaggerated concern, but I thought I'd throw it out there and see if anyone might want to comment.

Contract

I am publishing a web site called ThinkBanQ which is being developed by Mediacurrent, a local Drupal shop here in Atlanta. ThinkBanQ is primarily a forum for innovators invested in three major sectors. It employs many familiar social media tools designed to engage users and encourage greater participation as an open-sourced and self-determining community. Most significantly, this participation is semantically rendered, then valuated according to its contextual significance within the community. I like to think of it as “Facebook as if it mattered” or “LinkedIn on steroids.”
