RDF

Hello folks,

I'm learning how to create my first semantic website. I have created a content type with RDF mappings and I would like to try the Sparql queries in my site. I have installed the module http://drupal.org/project/sparql and I have enabled it. Now I have an endpoint enabled, but I don't the know the url of my site where I have to execute the queries.

Any ideas?

I'm a noob with this!

Hello all,
I would like to develop a genealogy application in Drupal. I wanted to see what has already been done specifically as it relates to using the Semantic Web. I know there are some genealogy modules but I'm interested in this from a Semantic Web perspective. I know that Drupal 7 supports RDFa out of the box, as it were. However, for Genealogy there are two specific vocabularies (at least) that one would want to use for Genealogy, that being BIO for biographic information and it has a focus around events in one's life. It is defined here:

Hi， guys

I want to develop a GUI tool for RDF annotation. The target is a) provide an efficient GUI for tagging b) tags can automatically be translated and stored as RDF. and i will use my own personal knowledge ontology.

But i found that nodes use rdf mapping to output data as RDFa which makes RDF not expandable for an existence node.

Any ideas to solve this problem?

Thanks.

The last few weeks have been pretty eventful for the semantic web in Drupal.

Lin Clark and I wrote a couple of articles for the IBM developerWorks explaining what it is possible to achieve with Drupal 7 and the recent developments in core and contrib. They are pretty detailed and will be useful materials for newbies willing to learn how to use the Semantic Web technologies in Drupal 7:

• The Semantic Web, Linked Data and Drupal, Part 1: Expose your data using RDF
• The Semantic Web, Linked Data and Drupal, Part 2: Combine linked datasets with Drupal 7 and SPARQL Views

Are there any guidelines/best practices for assigning URIs for Drupal Linked Data?

I've got the various modules publishing RDF just fine, and can get RDF from URIs like http://hostname/node/xyz/rdf, but this sort of URI is really an implementation detail, and therefore not in the spirit of linked data URIs. It would seem to be much more appropriate to have URIs that might read something like http://hostname/content-type/title.

I've tried using Pathauto, which rewrites the URLs well-enough, but doesn't provide the RDF as expected.

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.

I am willing to contribute to Drupal-7 as a Student in GSoC-2011. I came up with this idea while recently working on Drupal-7 for a Semantic-Web project.

Drupal 7 comes with an inbuilt core RDF module. There is a contributed RDF module as well which allows us to extend the functionality of the core module through :
1. RDFx
2. RDF-UI
3. Evoc

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.

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?

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).
