Jetpak: Jena
http://www.jeteye.com/jetpak/ce128f26-680c-43b2-bf9e-d03138d2f1e1Summary: This jetpack contains a set of links and notes concerning Jena.
Jetpak: OWL
http://www.jeteye.com/jetpak/5ad8c80a-2b70-467b-a2b6-d3f2fd2cc7b2Summary: This Jetpack contains a set of links and notes concerning OWL (the Web Ontology Language).
Link: Pellet Reasoner Homepage
Summary: Pellet is an open-source Java based OWL DL reasoner. It can be used in conjunction with both Jena and OWL API libraries and also provides a DIG interface. Pellet provides functionalities to see the species validation, check consistency of ontologies, classify the taxonomy, check entailments and answer a subset of RDQL queries
Link: Jena Homepage
Summary: Jena is a Java framework for building Semantic Web applications. It provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine.
Link: OWL Web Ontology Language Reference
Summary: This document contains a structured informal description of the full set of OWL language constructs and is meant to serve as a reference for OWL users who want to construct OWL ontologies.
Link: OWL Web Ontology Language Guide
Summary: This document demonstrates the use of the OWL language to
1) formalize a domain by defining classes and properties of those classes,
2) define individuals and assert properties about them, and
3) reason about these classes and individuals to the degree permitted by the formal semantics of the OWL language.
Link: OWL Web Ontology Language Semantics and Abstract Syntax
Summary: This document contains two formal semantics for OWL. One of these semantics is a direct, standard model-theoretic semantics for OWL ontologies written in the abstract syntax. The other is a vocabulary extension of the RDF semantics that provides semantics for OWL ontologies in the form of RDF graphs.
Link: OWL Web Ontology Language Overview
Summary: This document is written for readers who want a first impression of the capabilities of OWL. It provides an introduction to OWL by informally describing the features of each of the sublanguages of OWL.
note - Mon, 06 Nov 2006 09:18:41 GMT
OWL is a Web Ontology language. Where earlier languages have
been used to develop tools and ontologies for specific user communities
(particularly in the sciences and in company-specific e-commerce
applications), they were not defined to be compatible with the architecture
of the World Wide Web in general, and the Semantic Web in particular.
