RDF

SPARQL is a query language for pattern matching against RDF graphs. The syntax resembles SQL, making for a friendly learning curve, but SPARQL is far more powerful, enabling queries spanning multiple disparate (local or remote) data sources containing heterogeneous semistructured data.

Effortless content creation by retrieving attribute values from the Web to (pre-)fill your node type (cck) fields.

Available services include:

• Wikipedia, ISBNdb
• BibTex, attribute: value lists
• Google Scholar, Amazon, imdb -- to be updated

How does it work?

New nodes are created as follows:

Enables the creation of resource nodes which serve as references to remote content identified by URIs and published in RDF format.

Logs all outgoing mail from your site that uses proper Drupal APIs.

Any user with "access mail logger" permission will be able to read logs of outgoing mail from any user to any recipient, including new user welcome emails, password resets, triggered actions, Rules-based actions, and more.

Limit the amount of nodes or comments your users create over a given time period. This module has been rewritten to integrate with Rules. Instead of going to a page to assign limits you now just need to create rules. A default rule has been provided as an example.

When creating your rules there are now many hundreds of ways to implement your limits. Limits can be applied to roles, users, dates, or anything that can be accessed using PHP.

Views Datasource is a set of plugins for Drupal Views for rendering content in a number of shareable, reusable formats based on XML, JSON and XHTML. These formats allow content in a Drupal site to be easily used as data sources for Semantic Web clients and web mash-ups. Views Datasource plugins output content from node lists created in the Drupal Views interface in a variety of formats - XML data documents using schemas like OPML and Atom, RDF data documents using a vocabulary like FOAF, JSON data documents in a format like Exhibit JSON, and XHTML data documents using a microformat like hCard.

Flag is a flexible flagging system that is completely customizable by the administrator. Using this module, the site administrator can provide any number of flags for nodes, comments, users, and any other type of entity. Some possibilities include bookmarks, marking important, friends, or flag as offensive. With extensive views integration, you can create custom lists of popular content or keep tabs on important content.

Flags may be per-user, meaning that each user can mark an item individually, or global, meaning that the item is either marked or it is not marked, and any user who changes that changes it for everyone.

In this way, additional flags (similar to published and sticky) can be put on nodes, or other items, and dealt with by the system however the administration likes.

Codemetrics provides static code analysis and software metrics for PHP projects and Drupal codebases in particular.

To see this in action, check out the Broccoli project.

This is pretty much alpha code - it's still fairly experimental. Expect APIs to change without notice.

Potluck is a tool for remixing data on Exhibit-powered pages.

To benefit the most from RDF in Drupal, please use Drupal 7 and the RDF Extensions (RDFx). The RDF CCK module was designed for Drupal 6 and is no longer being supported. All its features have been moved into Drupal 7 and the RDFx module which include a better user interface and lots of new features.
