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, by following rdfs:seeAlso links, and by querying the Sindice search engine. The library is written in Java and is based on the Jena framework.
Have you tried OpenRefine previously known as GoogleRefine previously known as Gridworks? =) It is out and ready to be used, supported and extended. Good news: someone already LOD-enabled it for you. We provide a set of extensions either integrated with the latest version of OpenRefine, or being available for download separately.
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.
Best in class semantic search discovery tool

We are a champion for creators of art and knowledge. Digital Bazaar, Inc. develops technology and services to enable individuals and businesses to more easily buy and sell digital content via the Internet. Music, television, movies, research data and publishing are a few of the industries that we are helping to make the transition to Web-based business models.
The NeuroCommons project seeks to make all scientific research materials - research articles, knowledge bases, research data, physical materials - as available and as usable as they can be. We do this by fostering practices that render information in a form that promotes uniform access by computational agents - sometimes called "interoperability". We want knowledge sources to combine easily and meaningfully, enabling semantically precise queries that span multiple information sources.
inked data describes a method of publishing structured data so that it can be interlinked and become more useful. It builds upon standard Web technologies such as HTTP and URIs, but rather than using them to serve web pages for human readers, it extends them to share information in a way that can be read automatically by computers. This enables data from different sources to be connected and queried.[1]
KSL conducts research in the areas of knowledge representation and automated reasoning in the Artificial Intelligence Laboratory of the Department of Computer Science at Stanford University. Current work focuses on enabling technology for the Semantic Web, hybrid reasoning, explaining answers from heterogeneous applications, deductive question-answering, representing and reasoning with multiple contexts, knowledge aggregation, ontology engineering, and knowledge-based technology for intelligence analysts and other knowledge workers.
Extracting Structured Data from the Common Web Crawl
More and more websites have started to embed structured data describing products, people, organizations, places, events into their HTML pages. The Web Data Commons project extracts this data from several billion web pages and provides the extracted data for download. Web Data Commons thus enables you to use the data without needing to crawl the Web yourself.
The group was started at DrupalCon Barcelona 2007 and includes discussions on how to integrate the Semantic Web technologies into Drupal and list the various effort of the community towards enabling RDF in Drupal. Drupal 7 comes with native RDFa support in core. If you want extra RDF capabilities such as other serialization formats and SPARQL support, checkout the RDF Extensions, SPARQL and SPARQL Views contributed projects.
Splunk is software that provides unique visibility across your entire IT infrastructure from one place in real time. Only Splunk enables you to search, report, monitor and analyze streaming and historical data from any source. Troubleshoot application problems and investigate security incidents in minutes instead of hours or days, monitor to avoid service degradation or outages, deliver compliance at lower cost and gain new business insights from your IT data.
The Semantic Web is really unleashing a revolution of new abilities! Smart data, which are meaningful to computers, are enabling a technology shift that leads to a better trade-off between flexibility and simplicity.
The Inference Web is a Semantic Web based knowledge provenance infrastructure that supports interoperable explanations of sources, assumptions, learned information, and answers as an enabler for trust.
Weave (BETA 1.0) is a new web-based visualization platform designed to enable visualization of any available data by anyone for any purpose. Weave is an application development platform supporting multiple levels of user proficiency - novice to advanced - as well as the ability to integrate, disseminate and visualize data at "nested" levels of geography.
D2RQ is a declarative language to describe mappings between relational database schemata and OWL/RDFS ontologies. The D2RQ Platform uses these mapping to enables applications to access a RDF-view on a non-RDF database through the Jena and Sesame APIs, as well as over the Web via the SPARQL Protocol and as Linked Data.
A web-based service that enables individuals to manage the production, publication, promotion, and sales of electronic books (ebooks) and related digital content
A destination site for authors, illustrators, editors, graphic artists, and composers to network The proper name of the company revolutionizing book publishing and sales
vocab.getty.edu contains open metadata for the Getty Vocabularies. The data is described semantically following linked data principles using the Resource Description Framework (RDF) format. This format enables direct access and use of Vocabulary data by computer applications.

"OpenOffice OKKAM AddOn is a freeware software that integrates the OKKAM functionalities to the OpenOffice Writer. You can easily search semantic entities inside your documents and attach detailed
information about them. OKKAM AddOn enables to insert entities as footnote and annotation or as metadata
directly inside your OpenOffice documents."
A Semantic content editor based on TinyMCE WYSIWYG editor. RDFaCE is created as a proof of concept for WYSIWYM (What You See Is What You Mean) concept. WYSIWYM aims to enable end-users to easily annotate their content using RDFa and Microdata markups. RDFaCE employs external NLP APIs to suggest namespaces, properties, URIs and to automatically annotate content.
