RDF

Exhibit displays structured data in the form of rich visualizations that can be searched, filtered and sorted using faceted browsing.

Bitcache is a distributed content-addressable storage (CAS) system. It provides repository storage for bitstreams (colloquially known as blobs) of any length, each uniquely identified and addressed by a digital fingerprint derived through a secure cryptographic hash algorithm.

This is a module that provides a Bitcache-compatible data storage repository for Drupal and implements the Bitcache REST API for interoperability with the standalone Bitcache command-line and synchronization tools. The Drupal module includes storage adapters for the file system and for MySQL, PostgreSQL, SQLite and GDBM databases, with Amazon S3 support in the works.

RDF is a W3C standard for modeling and sharing distributed knowledge based on a decentralized open-world assumption. Any knowledge about anything can be decomposed into triples (3-tuples) consisting of subject, predicate, and object; essentially, RDF is the lowest common denominator for exchanging data between systems.

This module provides comprehensive RDF functionality and interoperability for the Drupal 6.x platform. For more information, read the introductory posting or watch the demo video. Be sure to subscribe to the Semantic Web group on groups.drupal.org to keep up with the latest happenings.

Provides a WebDAV API and file system-backed reference server implementation for Drupal 6.x.

Semantic Search is an alpha quality faceted search front end for Drupal using an RDF-store on the back end. The code is overdeveloped and un-drupalike in many places. But this module contains many proof of concepts - so at least check out the screenshots.

Combines several experimental features:

* uses an RDF store as a search index. The built in store is easy to use. Other RDF stores require Java and configuration.
* dynamically creates default search interfaces, for many searches per site, configurable via admin interfaces.

Semantic Search was formerly known as NINA.
NINA was developed with support from CivicActions and LINC, as well as current support from OHO Interactive.

I am looking for module contributors and comments.
Please take a look at in CVS!

Note: You will need an older version of ARC RDF store, or Sesame OpenRDF, and I am working to support ARC2 which is under active development.

The current release provides drop-in support for CCK and Taxonomy.

A live demo of the search interaction can be seen at: http://newahirc.org.

The Relationship Manager module is intended to allow free-form links between nodes, recording not just that one page relates to another, but HOW it relates.
The CVS repository has been cleared pending a rewrite for D6, proposed by atipton.
This module is to be considered inactive until that's ready.
