About

The Nokia Semantic Web Server is an RDF based application suite for metadata-driven web publishing and knowledge management. It is a central component of the Forum Nokia website, the Nokia Research Center website, and the Nokia Open Source website. It also serves as Nokia’s reference implementation of URIQA, the URI Query Agent model.

The Nokia Semantic Web Server suite is comprised of a number of modular semantic web services:

/uriqa? – a URIQA query portal, with rule-based inference functionality.

/new? – a query portal for obtaining information about recently published or updated resources, provided as RSS 1.0 or as RDF Facets; also with rule-based inference functionality.

/id? – a resource identifier generator, employing UUIDs and providing PURL functionality.

/query? – a metadata and free-text query portal, providing output results as RSS 1.0 feeds; with both metadata driven and crawler based indexing agents.

/search? – a human friendly search UI; which integrates with any conformant /query? portal.

/editor? – a web form based, ontology driven metadata editor with validation and user authentication & access control; which integrates with any conformant /uriqa? portal.

The core of these web services are provided as open source, and while most can be used “out of the box”, some require a moderate amount of configuration and customization depending on the requirements and constraints of the particular solution.
