SchemaWeb - RDF Schemas Directory - 0 views
-
"SchemaWeb is a directory of RDF schemas expressed in the RDFS, OWL and DAML+OIL schema languages. SchemaWeb is a place for developers and designers working with RDF. It provides a comprehensive directory of RDF schemas to be browsed and searched by human agents and also an extensive set of web services to be used by software agents that wish to obtain real-time schema information whilst processing RDF data. RDF Schemas are the critical layer of the Semantic Web. They provide the semantic linkage that 'intelligent' software needs to extract value giving information from the raw data defined by RDF triples. "

"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. Jena is open source and grown out of work with the HP Labs Semantic Web Programme. "

Knoodl is a tool for creating, managing, and analyzing RDF/OWL descriptions. Its many features support collaboration in all stages of these activities. Knoodl's key component is a semantic software architecture that supports Emergent Analytics. Knoodl is hosted in the Amazon EC2 cloud and can be used for free. It may also be licensed for private use as MyKnoodl.

A semantic web experiment with a focus on Ontology Visualisation and Querying. For an idea of what we are about: Check out jOWL, a javascript library for traversing OWL-RDFS documents (under development). Dig through the available Ontologies with the ontology Interface, find what you are looking for amidst the more than 70.000 information pages:
OpenCyc for the Semantic Web - 1 views

Now it is even easier to use the rich and diverse collection of real-world concepts in OpenCyc to bring meaning to your semantic web applications! The full OpenCyc content is now available both as downloadable OWL ontologies as well as via semantic web endpoints (i.e., permanent URIs). These URIs return RDF representations of each Cyc concept as well as a human-readable version when accessed via a Web Browser.

Platypus Wiki - The Semantic Wiki Wiki Web - 0 views
-
Platypus Wiki is a project to develop an enhanced Wiki Wiki Web with ideas borrowed from the Semantic Web. It offers a simple user interface to create wiki pages with metadata based on W3C standards. It uses RDF (Resource Description Framework), RDF Schema and OWL (Web Ontology Language) to create ontologies and manage metadata.Platypus Wiki is an ongoing open source project started on 23th December 2003. The project is actually hosted on SourceForge and licensed under GNU GPL.

The Semantic Web is a vision for extending the Web so that machines can more intelligently integrate and process the wealth of information that is available. Unlike HTML and ordinary XML, Semantic Web languages allow semantics (i.e., meaning) to be explicitly associated with the content. The semantics are formally specified in ontologies, which can be shared via the Internet and extended for local needs. The current standard for the Semantic Web is OWL, a W3C Recommendation. The Semantic Web and Agent Technologies (SWAT) lab is investigating many of the issues needed to realize the Semantic Web vision.

A semantic wiki is a wiki that stores some portion of its data in a way that can be queried elsewhere. Typical uses of such data include querying it within the wiki (sometimes using standard query languages like SPARQL), aggregating it in displays like tables, maps and calendars; exporting it via formats like RDF, OWL or CSV; and reasoning with it, to calculate new facts from the given facts. Semantic wikis do not necessarily need to include standards or technologies considered part of the Semantic Web, although they usually do, to some extent.

LOV, your entry point to the growing ecosystem of linked open vocabularies (RDFS or OWL ontologies) used in the Linked Data Cloud. Here you will find vocabularies listed and individually described by metadata, classified by vocabulary spaces, interlinked using the dedicated vocabulary VOAF. You will enjoy querying the LOV dataset either at vocabulary level or at element level, exploring the vocabulary content using full-text faceted search, and finding metrics about the use of vocabularies in the Semantic Web.

The LOV dataset contains the description of RDFS vocabularies or OWL ontologies defined for and used by datasets in the Linked Data Cloud. Whenever available each vocabulary includes references to the datasets using it, in particular those listed in CKAN.
Project Vocabulary Specification - 0 views
-
This document specifies a vocabulary for describing projects independently of the project domain (e.g. software product development, fundraising, painting the garage). The intended architecture is primarily goal-oriented, that a project will consist of goals which may be broken down into subgoals and may be satisfied by completing a set of associated tasks. The vocabulary is constructed using the Resource Description Framework (RDF) and the Web Ontology Language (OWL). It may be used in conjunction with other RDF vocabularies such as FOAF or as an RSS 1.0 module.
Semantic Web - W3C - 0 views

"In addition to the classic "Web of documents" W3C is helping to build a technology stack to support a "Web of data," the sort of data you find in databases. The ultimate goal of the Web of data is to enable computers to do more useful work and to develop systems that can support trusted interactions over the network. The term "Semantic Web" refers to W3C's vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as RDF, SPARQL, OWL, and SKOS."
