Green Turtle is an implementation of RDFa 1.1 for browsers. By simply including a bit of Javascript, the DOM is extended to include the RDFa API and an RDFa 1.1 processor is available to process any ancillary documents to harvest triples. For more information on the API, see RDFa API Working Draft at the W3C.

playground for working with RDF.rb, a Ruby toolkit for working with the Semantic Web and Linked Data. RDF.rb is composed of a number of RubyGems, most implemented in pure Ruby, that implement various aspects of the Resource Description Framework, the language of the Semantic Web.

The implementation is based on the TERRIER information retrieval framework and supports the following features: build an inverted index of a Wikipedia Database provided in the original MediaWiki database schema compute ESA vectors for any text compute Cosine Similarity of ESA vectors (which can be used as semantic similarity measure)

"Big Data Public Private Forum (BIG) is working towards the definition and implementation of a clear strategy that tackles the necessary efforts in terms of research and innovation, while also it provides a major boost for technology adoption and supporting actions for the successful implementation of the Big Data economy."

With RDFa, you can easily include extra "structure" in your (X)HTML to indicate a calendar event, contact information, a document license, etc… RDFa is about total publisher control: you choose which attributes to use, which to reuse from other sites, and how to evolve, over time, the meaning of these attributes.This site tracks RDFa specifications, implementations, and news of all sorts. If you have an RDFa implementation, add it to the wiki.

The Virtuoso SPARQL query service implements the SPARQL Protocol for RDF (W3C Working Draft 25 January 2006) providing SPARQL query-processing for RDF data available on the open internet. The query service implementation extends the standard protocol by providing multiple output-formats alongside the standard XML results serialization. At present this uses additional query parameters, although content-negotiation will be supported soon.

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.

This wiki is for connecting the W3C communities (Web developers, implementers, people who make the W3C specifications). The W3C has a formal track for making standards specifications. The specs answer a lot of questions, but not all of them. The wiki is used by many communities such as the Open Web Platform and the Semantic Web. You might want to contribute to W3C work

The lod.euscreen.eu/resource/ pilot is an initial attemp of making the EUscreen content availiable as Linked Open Data on the web. It allows users not only to access and retrieve metadata from the EUScreen content,via standard Web technologies, but also to discover relevant data within the multitude of the available content and even to implement applications that integrate data from EUScreen collection.

The RDFa Test Suite provides an interactive mechanism to check the conformance of an RDFa processor and SPARQL query engine. This service is intended for anybody that wants to see how RDFa works as well as developers that want to do conformance testing on their own RDFa/SPARQL implementations.

Wikicat is the bibliographic catalog used by the Wikicite and WikiTextrose projects. It will be implemented as a Wikidata dataset using a datamodel design based upon IFLA's Functional Requirements for Bibliographic Records: final report (FRBR) [1], the various ISBD standards, the Library of Congress's MARC 21 specification, the Anglo-American Cataloguing Rules' The Logical Structure of the Anglo-American Cataloguing Rules and Resource Description and Access (RDA), and the International Committee for Documentation (CIDOC)'s Conceptual Reference Model (CRM)[2]. The history and inter-relation of these various cataloging standards is described in RDA presentations.

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 Sentikator is a computer linguistic engine designed to calculably recognize, analyze and quantify emotions and content in texts. It allows extracting sentiment out of news, analyst recommendations, social media data, transcripts, press releases, broker news, factsheets, weather forecasts and many other sources. Sentiment extraction is highly reliable and disseminated data is preprocessed so that implementation into existing or new financial applications is easily possible. The Sentikator gives valuable insights to emotions"

"The OpenLink Data Explorer, or ODE, (formerly known as the OpenLink RDF Browser) is an RDF Data Browser implemented by OpenLink Software using the open source OpenLink AJAX & AJAR Toolkit (OAT). ODE provides a Web browser driven interface for interacting with RDF-based Linked Data via a combination of (X)HTML, AJAR, and Hyperdata links."

"The goal of Apache Marmotta is to provide an open implementation of a Linked Data Platform that can be used, extended and deployed easily by organizations who want to publish Linked Data or build custom applications on Linked Data."

EUCLID is a European project facilitating professional training for data practitioners, who aim to use Linked Data in their daily work. EUCLID delivers a curriculum implemented as a combination of living learning materials and activities (eBook series, webinars, face‐to‐face training), validated by the user community through continuous feedback.

a collection of semantic resources in order to ease the implementation of semantic Django web apps. Why? Just because data is more important than code and if you store, manipulate, give access to your data in a standard way you'll be able to interact with other website as part of the Giant Global Graph. Isn't it fun?

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.
