URIQA Semantic Web Service for RDF Gateway URIQA (URI Query Agent) is a model for knowledge discovery, both from authoritative sources as well as from arbitrary third party sources, based solely on the URI denoting a particular resource. This is the complete URIQA service implementation currently deployed on the Nokia Semantic Web Server. Includes a Client API for deploying URIQA enlightened semantic web agents. |

|
URIQA Semantic Web Service for RDF Gateway (Pilot) This is the original pilot implementation of the URIQA service developed for the Nokia Semantic Web Server. Includes partial, experimental support for queries expressed using RDFQ, serialized using either RDF/XML or Turtle. Includes a Client API for deploying URIQA enlightened semantic web agents. |

URIQA Prototype in Java An early prototype of a URIQA implementation in Java. Incomplete and now obsolete, but likely providing some useful code for those working on Java implementations of URIQA. |

TriX: RDF Triples in XML TriX is an experimental alternative serialization for expressing RDF triples in XML which aims to provides a highly normalized, consistent XML representation for RDF graphs, allowing the effective use of generic XML tools such as XSLT, XQuery, etc. See also the Named Graphs and TriX web site. |

RDF Datatyping API This is an alpha-quality experimental Java interface for deploying support for RDF Datatyping, including (partial) support for XML Schema datatypes, UAProf datatypes, and a few proprietary Nokia datatypes. It was developed to test certain ideas and characteristics of RDF Datatyping during the development of the revised W3C RDF specification. It is not currently maintained but may prove useful as a starting point for further development. |

RDFL - An Ontology for Describing Lexical Datatypes RDFL is an ontology for defining and relating lexical datatypes, which serves as a convenient mechanism for validation and/or interpretation of RDF typed literals. It can also be used solely for defining the relations between datatypes leaving the definition of and interpretation by their lexical spaces to other applications. |

|
RDFX: An XML Serialization for RDF RDFX is an experimental alternative serialization for expressing RDF statements in XML which offers several benefits over the standard RDF/XML serialization. RDFX is not intended as a present-day replacement for the standard RDF/XML serialization, but is provided for consideration if/when a new standardized XML serialization for RDF is defined. |
