Freaky. Look under Examples and try Einstein and Godel. "RelFinder is a tool based on Adobe Flex that automatically reveals relationships within a set of known objects via arbitrary SPARQL endpoints and displays them as graph visualization. The relationships are found by an algorithm that can be applied to large RDF knowledge bases, such as DBpedia or the whole LOD-Cloud. Since the graph that visualizes the relationships can still become large, we added interactive features and filtering options to the user interface that enable a reduction of displayed nodes and facilitate understanding."
In fact, the UK government is committed to publishing data as linked data because they are convinced it is the best approach available for publishing data in a hugely diverse and distributed environment, in a gradual and sustainable way.
RDFa is a specification for attributes to be used with XHTML or SVG Tiny to express structured data. The rendered, hypertext data of XHTML is reused by the RDFa markup, so that publishers don’t need to repeat significant data in the document content. The underlying abstract representation is RDF, which lets publishers build their own vocabulary, extend others, and evolve their vocabulary with maximal interoperability over time. pyRdfa is a distiller that generates the RDF triples from an (X)HTML+RDFa or SVG Tiny 1.2 file in various RDF serialization formats. It can either be used directly from a command line or via a CGI service. It corresponds to the RDFa Recommendation, published on the 14th of October, 2008, and, for the SVG version, to the SVG Tiny 1.2 Recommendation, published on the 22nd of December, 2008.
"The Data Browser Extension provides a table-based display for RDF data on the Semantic Web. Using AJAX code from the Tabulator Semantic Web Browser, the Data Browser Extension makes RDF data readable to the average person and shows how data are linked together across different sites. Queries can be generated for display in tables, calendars, maps, and timelines."
"RDFLib is a Python library for working with RDF, a simple yet powerful language for representing information. The library contains an RDF/XML parser/serializer that conforms to the RDF/XML Syntax Specification (Revised) ."
"The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description Language, and gives an overview of some deployed RDF applications. It also describes the content and purpose of other RDF specification documents."
"Being able to reuse RDF vocabularies across sites is one of the key elements for the semantic web to take off. The RDF external vocabulary importer module (evoc) will cache any external RDF vocabulary in Drupal, and expose its classes and properties to other modules. RDFCCK relies on evoc to offer classes and properties to be mapped to CCK fields, node title and body."
