Here is a short overview and comparison of RDF querying with SPARQL and Jena which is presented as follows: 1. SPARQL; 2. SPARQL from inside Jena; 3. Explicit and implicit relations when querying with Jena 4.Querying remote SPARQL endpoitns
OntospyWeb is a tool made for navigating ontologies ('vocabularies') encoded using the RDF family of languages. It is based on the Ontospy Python library, which in turns wraps RDFLib.

Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods.
W3C POWDER Working Group. The POWDER Working Group is specifying a protocol for publishing descriptions of (e.g. metadata about) Web resources using RDF, OWL, and HTTP.
The Resource Description and Access (RDA) standard, due to be released this coming summer, has included since May 2007 a parallel effort to build Semantic Web enabled vocabularies. This article describes that effort and the decisions made to express the vocabularies for use within the library community and in addition as a bridge to the future of library data outside the current MARC-based systems. The authors also touch on the registration activities that have made the vocabularies usable independently of the RDA textual guidance. Designed for both human and machine users, the registered vocabularies describe the relationships between FRBR, the RDA classes and properties and the extensive value vocabularies developed for use within RDA.
This is a specification of a precise semantics, and corresponding complete systems of inference rules, for the Resource Description Framework (RDF) and RDF Schema (RDFS).
