Versa (query Language)

Versa (query Language)

Versa is an RDF query language, that is, a query language for databases, able to retrieve and manipulate data stored in Resource Description Framework (RDF) format. Versa differs from most other RDF query languages, which are typically based on SQL or specialized XML vocabularies. Although the design of Versa was inspired by XPath, its compact, functional syntax also somewhat resembles Lisp. As of 2006, the only Versa implementation is in the Python-language, open source 4Suite XML framework.
