Metadata Management Associates is a partnership of experienced consultants devoted to the development of intelligent metadata management solutions and services, particularly in library and digital library environments. MMA consultants have advised or developed systems for a variety of clients, and are particularly focused on providing solutions that enable data to operate fully within the Semantic Web.

ConceptBase.cc is a multi-user deductive database system with an object-centered data model. Its ability to represent information at any abstraction level (data, class, metaclass, meta-metaclass, etc.) makes it a powerful tool for metamodeling and engineering of customized modeling languages. The system is accompanied by a highly configurable graphical user interface that builds upon the logic-based features of the ConceptBase.cc server.

RDFLib is a Python library for working with RDF, a simple yet powerful language for representing information. The library contains parsers and serializers for RDF/XML, N3, NTriples, Turtle, TriX and RDFa. The library presents a Graph interface which can be backed by any one of a number of store implementations, including, memory, MySQL, Redland, SQLite, Sleepycat, ZODB and SQLObject.

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.

Currently this site is mainly a collection of notes supporting the business cases and development of Linked Data and Semantic Web applications. The long term goal is to evolve these notes into a set of strategies for developing Semantic Web applications for a nominated domain.

The Open Data Protocol (OData) is a Web protocol for querying and updating data that provides a way to unlock your data and free it from silos that exist in applications today. OData does this by applying and building upon Web technologies such as HTTP, Atom Publishing Protocol (AtomPub) and JSON to provide access to information from a variety of applications, services, and stores. The protocol emerged from experiences implementing AtomPub clients and servers in a variety of products over the past several years. OData is being used to expose and access information from a variety of sources including, but not limited to, relational databases, file systems, content management systems and traditional Web sites.

Semantic Web Conference Corpus - a.k.a. the Semantic Web Dog Food Corpus! Here you can browse and search information on papers that were presented, people who attended, and other things that have to do with the main conferences and workshops in the area of Semantic Web research.

is a tool providing support for agile, distributed knowledge engineering scenarios. OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.

Our goal is to make it easier for people to collect, organize, find, visualize, and share their information. We are an interdisciplinary group of researchers blending approaches from human-computer interaction, social computing, databases, web infrastructure, information retrieval, artificial intelligence and the semantic web.

Integrate Knowledge - The Efficient, Flexible And Collaborative Way

The science of searching. W3lab is an applied research laboratory for Computational Linguistics, Information Retrieval and the Semantic Web.

ARCOE aims at bringing together researchers and practitioners from core areas of Artificial Intelligence (Knowledge Representation and Reasoning, Contexts, and Ontologies) to discuss these kinds of problems and relevant results.

A WebID is a way to uniquely identify a person or other entity, such as a company, an organization, a web site, or other resource. The term "WebID" was coined by Dan Brickley and Tim Berners-Lee in 2000. As of 2010, the term "WebID" is used for a class of solutions, not any one technology. W3C may attempt to standardize one particular identity technology, which may use the term "WebID" more definitively. One of the current approaches using the name "WebID" is the FOAF+SSL WebID, a certificate-based solution. However, the concept of a WebID does not always depend upon FOAF (Friend-of-a-Friend).

the metaweb project ~ find and be found The MetaWeb Project is an example application for the exchange of messages in the Semantic Web. It offers the possibility to add individual and standardised markings on Websides, Blogs, Feeds, Images or Web Services. On the other hand it is possible to create search profiles with the same method, so that the hits are of a high quality because of the matching of the meta descriptions. Markings and search profiles can be given out in the RDF format or be parsed on the pages CodeInput (for markings) and AnglerInput (for search profiles).

The Freebase Commons contains the types used to administer the Freebase application. Much of the content and the display preferences for types in the application is managed here. More
