Named Graphs is the idea that having multiple RDF graphs in a single document/repository and naming them with URIs provides useful additional functionality built on top of the RDF Recommendations.

Triplify provides a building block for the semantification of Web applications. Triplify is a small plugin for Web applications, which converts database content into RDF or JSON feeds and provides a Linked Data interface.

Over 10 billion pieces of reusable information can already be found across 100 million web pages which embed RDF and Microformats. Start consuming this data today with Sindice Data Web services.

SMOB is a distributed / decentralised microblogging system built on RDF and Semantic Web technologies, mainly SIOC and FOAF. Currently, we have simple prototypes of a publishing and an aggregating service, less than 100 lines of PHP code each. Code at http://code.google.com/p/smob/

The Sematic Web Client Library represents the complete Semantic Web as a single RDF graph. The library enables applications to query this global graph using SPARQL- and find(SPO) queries. To answer queries, the library dynamically retrieves information from the Semantic Web by dereferencing HTTP URIs and by following rdfs:seeAlso links. The library is written in Java and is based on the Jena framework.

HarvANA uses a standardized but extensible RDF model for representing the annotations/tags and OAI-PMH to harvest the annotations/tags from distributed community servers. The harvested annotations are aggregated with the authoritative metadata in a centralized metadata store.

The Bio2RDF project is a tool to convert bioinformatics data and knowledge bases to RDF format. It is a kind of generalized rdfizer for bioinformatics applications, and it is a place for the semantic web life science community to develop and grow.

Dedicated to the publication and use of multilingual RDF descriptions of human languages, to be used as Linked Data.

/facet is a generic browser for heterogeneous semantic web repositories. The browser works on any RDFS dataset without any additional configuration.

KHarvester (Informal Knowledge Harvester) is a SOA layer which collects RDF data from web pages. It provides REST based Web Services for managing data available on Social Semantic Information Sources (SSIS): semantic blogs, semantic wikis, and JeromeDL (the Social Semantic Digital Library). These Web Services allow saving harvested data in the informal knowledge repository, and providing them in a form of informal Learning Objects (LOs) that are described accroding to LOM (Learning Object Metadata) standard. Also, IKHarvester is an extension to Didaskon system. Didaskon (διδάσκω - gr. teach) delivers a framework for composing an on-demand curriculum from existing Learning Objects provided by e-Learning services (formal learning). Moreover, the system derives from SSIS which provide informal knowledge. Then, the selection and work-flow scheduling of Learning Objects is based on the semantically annotated specification of the user's current skills/knowledge (pre-conditions), anticipated resulting skills/knowledge (goal) and technical details of the clients platform.

LODr is a RDF-based (re-)tagging service, that allows people to weave their Web 2.0 tagged data into the Linked Data Web and provides a dedicated browsing interface.

ClioPatria is the award winning, SWI-Prolog-based platform for Semantic Web Applications. It joins the SWI-Prolog RDF and HTTP infrastructure with a SeRQL/SPARQL query engine, interfacing to the The Yahoo! User Interface Library (YUI) and libraries that support semantic search.

Primary Objectives * Build a demo that spans from bench to bedside using RDF and OWL. * Explore the effectiveness of current tools. * Document our finding to help accelerate adoption of the Semantic Web.

This summary was born out of a question on Twitter and percolated to FriendFeed, which was "Who is using RDF and integrating other resources at the minute and what are those resources? From this question, several resources were highlighted

Semantic CrunchBase is an RDF/SPARQL interface to CrunchBase, the free directory of technology companies, people, and investors.

This is the home page for the National Science Digital Library Metadata Registry. The Metadata Registry provides services to developers and consumers of controlled vocabularies and is one of the first production deployments of the RDF-based Semantic Web Community's Simple Knowledge Organization System (SKOS)

See also: http://lists.w3.org/Archives/Public/semantic-web/2008Apr/0005.html NaturalOWL is an open-source natural language generation engine written in Java. It produces descriptions of individuals (e.g., items for sale, museum exhibits) and classes (e.g., types of exhibits) in English and Greek from OWL DL ontologies. The ontologies must have been annotated in RDF with linguistic and user modeling resources. We demonstrate a plug-in for Protege that can be used to produce these resources and to generate texts by invoking NaturalOWL. We also demonstrate how NaturalOWL can be used by robotic avatars in Second Life to describe the exhibits of virtual museums. NaturalOWL demonstrates the benefits of Natural Language Generation (NLG) on the Semantic Web. Organizations that need to publish information about objects, such as exhibits or products, can publish OWL ontologies instead of texts. NLG engines, embedded in browsers or Web servers, can then render the ontologies in multiple natural languages, whereas computer programs may access the ontologies directly.

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.

Welcome to the National Center for Biomedical Ontology's BioPortal. BioPortal is a Web-based application for accessing and sharing biomedical ontologies. New features in BioPortal 2.0 include: * Full ontology navigation using Flash visualization * Web-service access to BioPortal content and capabilities, which enables developers to use our BioPortal services in their tools. * Ability to add Marginal Notes to classes in BioPortal ontologies, a feature that enables the community to comment on ontologies and to discuss their contents * Ability to create Point to Point Mappings between concepts in different BioPortal ontologies * Bulk export of ontology-to-ontology mappings in RDF format * Navigation of multiple ontologies, which enables users to have several ontologies opened simultaneously in different tabs in the user interface * URIs for all ontology content, which enable developers to access and share BioPortal content from their applications * Improved support through Protégé for ontologies in OWL format
