Resource Description Framework (RDF) is a general-purpose language for representing information in the Web. This document defines a textual syntax for RDF called Turtle that allows an RDF graph to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes. Turtle provides levels of compatibility with the existing N-Triples format as well as the triple pattern syntax of the SPARQL W3C Recommendation.

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.

A simple online RDF Turtle editor that allows you to render an RDF graph visually, restrict to sub-graphs via SPARQL and to export the visualisation as SVG.

RDF format transformations http://triplr.org/output/source-uri output-format is one of html, json, ntriples, rdf or turtle.  source-uri is like example.org/foo/bar

LODSPeaKr is a small and simple system that allows you to publish your RDF data in a fast way and without much effort. LODSPeaKr allows you to publish your data in several machine-processable syntaxes (RDF/XML, Turtle, N-Triples) as well as in HTML.

A simple but powerful service that delivers RDF-based structured descriptions of Web addressable resources (documents or real world objects) in a variety of formats through Generic HTTP URIs. The underlying technology is Virtuoso's Sponger, which takes an existing Web-accessible resource (webpage, media) and generates an RDF graph of its metadata using existing well-known ontologies as well as site-specific knowledge. URIBurner then re-presents this data as either a new HTML webpage, or directly as RDF in a variety of serializations (RDF/XML, text/n3, turtle, JSON).

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.

Anything To Triples (any23) is a library, a web service and a command line tool that extracts structured data in RDF format from a variety of Web documents. Currently it supports the following input formats: RDF/XML, Turtle, Notation 3, RDFa. Microformats: Adr, Geo, hCalendar, hCard, hListing, hResume, hReview, License, XFN and Species
