OWLIM is a family of semantic repositories, or RDF database management systems, with the following characteristics:
native RDF engines, implemented in Java
delivering full performance through both Sesame and Jena
robust support for the semantics of RDFS, OWL 2 RL and OWL
The intention of this service is to simplify a common task in the work of RDF developers: remembering and looking up URI prefixes.
You can look up prefixes from the search box on the homepage, or directly by typing URLs into your browser bar, such as http://prefix.cc/foaf or http://prefix.cc/foaf,dc,owl.ttl.
LOV, your entry point to the growing ecosystem of linked open vocabularies (RDFS or OWL ontologies) used in the Linked Data Cloud. Here you will find vocabularies listed and individually described by metadata, classified by vocabulary spaces, interlinked using the dedicated vocabulary VOAF.
You will enjoy querying the LOV dataset either at vocabulary level or at element level, exploring the vocabulary content using full-text faceted search, and finding metrics about the use of vocabularies in the Semantic Web.
The Web of Data has many equivalent URIs.
This service helps you to find co-references between different data sets. Enter a known URI, or use Sindice to search first.
