RDFLib

Have a project using rdflib you'd like to have listed here? If so, assert that your doap:Project has doap:category of http://rdflib.net/projects#using_rdflib and send us a pointer to your doap (for now leave a comment on this page).

• FOAF Utils

  FOAF utils tools.

• Semantic Web Archive of Mailing Lists

  SWAML is a research project around the semantic web tecnologies to publish the mailing lists's archive into an RDF format.

• Vapour

  A web-based validator tool to check the compliance of a web site against the recipes described in the Best Practices for Publishing RDF Vocabularies (W3C Working Draft).

• Emeka

  Emeka is a programmable IRC bot (implemented in Python) which provides services for querying remote RDF resources. In particular, Emeka's command library provides common services associated with RSS and FOAF resources. The short-term goal was to be a tool for learning Versa by example usage as well as to demonstrate the ability of IRC and RDF to serve as a framework for building Agents (in the traditional AI sense). The long-term goal is for Emeka to demonstrate the true value of RDF: machine readability and ontological commitment.

• Fantasy Fame Game

  (unreleased)

• FuXi

  FuXi (pronounced foo-shee) is a forward-chaining production system for Notation 3 Description Logic Programming. It is implemented as a companion to RDFLib – which it requires for its various RDF processing.

• GRDDLpy

  As an exercise, I wrote (from scratch) a GRDDL implementation for RDFLib and 4Suite and ported testHarness.py to work with the implementation (it uses RDFLib for processing the test manifest and a graph isomorphism mechanism to properly check non-lean graphs for equivalence)

• InfixOWL

  An infix syntax for Python, Manchester OWL, OWL Abstract Syntax, and RDF (via RDFLib).

• Oort

• gasuse

• stellaris

  Stellaris is a metadata management service developed within the AstroGrid-D project. Our focus is to provide a flexible way to store and query metadata relevant for e-science and grid-computing. This can range from resource description of grid resources (compute clusters, robotic telescopes, etc.) to application specific job metadata or dataset annotations. We use common web-standards such as RDF to describe metadata and the accompanying query language SPARQL. Some features of the software include: * A simple but powerful management interface for RDF-graphs * Different backends for persistence through the use of RDFLib and Virtuoso * Authorization and authentication based on X.509-certificates * Supports different ways of VO-based authorization such as VOMRS * SPARQL-protocol implementation with both XML/JSON result formats
