The goals of this effort is to design and implement a configurable and extensible semantic eScience framework. Configuration will require some research into accommodating different levels of semantic expressivity and user requirements from use cases. Extensibility will be achieved in a modular approach to the semantic encodings (i.e. ontologies) performed in a community setting, i.e. an ontology framework into which specific applications all the way up to communities can extend the semantics for their needs.

This project, the Semantically-Enabled Science Data Integration (SESDI), will demonstrate how ontologies implemented within existing distributed technology frameworks will provide essential, re-useable, and robust, support for an evolution to science measurement processing systems (or frameworks) as well as for data and information systems (or framework) support for NASA Science Focus Areas and Applications.

The LDSpider project provides a web crawling framework for the Linked Data web. Requirements and challenges for crawling the Linked Data web are different from regular web crawling, thus the LDSpider project offers a web crawler adapted to traverse and harvest content from the Linked Data web.

CubicWeb is a semantic web application framework, licensed under the LGPL, that empowers developers to efficiently build web applications by reusing components (called cubes) and following the well known object-oriented design principles. Its main features are: an engine driven by the explicit data model of the application , a query language named RQL similar to W3C's SPARQL ,

open semantic framework, or OSF, is a combination of a layered architecture and modular software. It is the most comprehensive framework within this OpenStructs site; many of the other aspects of OpenStructs are components within OSF. PDF

"Federated Knowledge Extraction Framework FOX is a framework that integrates the Linked Data Cloud and makes use of the diversity of NLP algorithms to extract RDF triples of high accuracy out of NL. In its current version, it integrates and merges the results of Named Entity Recognition tools. Keyword Extraction and Relation Extraction tools will be merged soon."

The LDSpider project aims to build a web crawling framework for the linked data web. Requirements and challenges for crawling the linked data web are different from regular web crawling, thus this projects offer a web crawler adapted to traverse and harvest sources and instances from the linked data web. We offer a single jar which can be easily integrated into own applications.

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.

"he Semantic Web is an extension of the World Wide Web through standards set by the World Wide Web Consortium (W3C).[1] The goal of the Semantic Web is to make Internet data machine-readable. To enable the encoding of semantics with the data, technologies such as Resource Description Framework (RDF)[2] and Web Ontology Language (OWL)[3] are used. These technol"

Callimachus (kəlĭm`əkəs) is a Semantic Web framework for easily building hyperlinked Web applications.  Callimachus allows Web authors to quickly and easily create Semantically-enabled Web applications with a minimal knowledge of Semantic Web principles.

The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. It is a collaborative effort led by W3C with participation from a large number of researchers and industrial partners. It is based on the Resource Description Framework (RDF). See also the separate FAQ for further information.

"The Resource Description Framework (RDF) is a framework for representing information in the Web. This document defines an abstract syntax (a data model) which serves to link all RDF-based languages and specifications. The abstract syntax has two key data structures: RDF graphs are sets of subject-predicate-object triples, where the elements may be IRIs, blank nodes, or datatyped literals. They are used to express descriptions of resources. RDF datasets are used to organize collections of RDF graphs, and comprise a default graph and zero or more named graphs. RDF 1.1 Concepts and Abstract Syntax also introduces key concepts and terminology, and discusses datatyping and the handling of fragment identifiers in IRIs within RDF graphs."

"DLMA represents the standards-setting representatives of over 530 of the leading digital publishing, educational technology and e-learning organizations worldwide via its stakeholder organizations. Collectively the DLMA stakeholder organizations have over 60 years tenure as successful standards-setting organizations. Our mission is to coordinate metadata standards adoption and development in support of digital learning and education across the educational technology, publishing, web and library communities via existing metadata frameworks while encouraging innovation and the evolution to next generation metadata frameworks."

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.

UMBEL Web services are supported by the structWSF Web services framework. The latest version of the UMBEL ontology has been indexed by the structWSF instance, and gets exposed to the generic public through these services.
