Tuples (triples) for TRAK architecture viewpoints and views
...TRAK is a general systems-thinkers'/system engineering enterprise architecture framework. It is simple, user-friendly, pragmatic and not limited to IT. 100% triple-centric and semantically-sound. Forms basis for RDF + OWL ontology description - see https://trakmetamodel.sourceforge.io/vocab/TRAK_metamodel.html. Each TRAK metamodel element now has its own web page - see https://trakmetamodel.sourceforge.io/metamodel/index.html
Jena is Java toolkit for developing semantic web applications based on W3C recommendations for RDF and OWL. It provides an RDF API; ARP, an RDF parser; SPARQL, the W3C RDF query language; an OWL API; and rule-based inference for RDFS and OWL.
Jena is now an Apache project:
http://jena.apache.org/
...Developers need to download Eclipse, install the RCP support, the Fatjar plugin and the Delta Pack in one of the 3.x flavors.

A Windows GUI application for RDF. SWC is a client tool for a Sesame 2 RDF server or SPARQL endpoint, and can be used as a out-of-the-box local triplestore. It offers advanced SPARQL querying and handles Sesame server administrative tasks.
This tool is no longer actively maintained as my priorities and interests have shifted away from .Net development. If you are interested in taking over, drop me a line.

The Bio2RDF project aims to transforms silos of life science data into a globally distributed network of linked data for biological knowledge discovery. Bio2RDF creates and provides machine understandable descriptions of biological entities using the RDF/RDFS/OWL Semantic Web languages. Using both syntactic and semantic data integration techniques, Bio2RDF seamlessly integrates diverse biological data and enables powerful new SPARQL-based services across its globally distributed knowledge bases.
Ontology Design Patterns (ODPs) are well known and efficient modeling solutions for ontologies. This public catalog offers a collection of well documented and tested ODPs, including examples from the biological knowledge domain, implemented in OWL.
The “RDB2RDF Mapper” is a Java based software desktop application which allows a user to create a mapping file between a relational database and an RDFS/OWL ontology via a graphical user interface. This project is ANDS-funded.
Relational.OWL automatically extracts the semantics of virtually any relational database and transforms this information automatically into RDF/OWL, processable by a wide majority of Semantic Web applications.
Complete Studio Web Management system, created in PHP/MySQL using Ajax tecnology, with sessions treatment and optimized data base access. In the new version (2.0v) will to use the frameworks xajax, ActiveWidgets and jsDOMenuBar.
Algernon is a rule-based reasoning engine written in Java. It allows forward and backward chaining across Protege knowledge bases. In addition to traversing the KB, rules can call Java functions and LISP functions (from an embedded LISP interpreter)
D2R MAP is a declarative language to describe mappings between relational database schemata and OWL ontologies. This D2R processor implements the D2R mapping language and exports data from a relational database as RDF, N3, N-TRIPLES or as Jena models.
OntoCardio is an initiative to build ontologies for the legacy Cardio Database (Resource of bioinformation on cardiovascular diseases). SMI's Protege and its OWL plug-in has been adopted as the ontology construction and programming framework.
A translator that converts information models written in ISO-10303-11 EXPRESS to DAML+OIL/OWL (e2ont). The software extends the OSEXPRESS parser. DAML+OIL or OWL code is obtained using the Jena2 Semantic Web framework.
Scidoc N6 is a platform for collaborative research and learning based on Semantic Web standards like RDF and OWL. It supports dynamically evolving conecpt models as a foundation for various kinds of information systems.
A new front-end for the Protege (protege.stanford.edu) knowledge management and ontology development software that mimics the "Windows Explorer" interface to make it easier to deal with RDF and similiar "semantic web" structured data stores.
