Rasqal RDF Query Library Publisher's description
from Dave Beckett
Rasqal RDF Query Library is a C library that handles Resource Description Framework (RDF) query syntaxes, query construction and query execution returning result bindings.
Rasqal is a free software / Open Source C library that handles Resource Description Framework (RDF) query syntaxes, query construction and query execution returning result bindings. The supported query languages are SPARQL and RDQL. gs. The sgt;
Rasqal was designed to work closely with the Redland RDF library but is entirely separate. It is intended to be a portable library working across many POSIX systems (Unix, GNU/Linux, BSDs, OSX, cygwin) win32 and others.
This is a beta quality library - the code is mature but the API is still changing and the SPARQL support is under active development.
- An RDF query construction and access API.
- A query execution engine including constraint expression evaluation.
- A query result binding API.
- Query language support for SPARQL.
- Query language support for RDQL.
- Triple store querying APIs to support running over external RDF graphs.
- No memory leaks.
- roqet standalone RDF query utility program
Rasqal does not provide an RDF API or triple store, but relies on external libraries implementing the triple store API providing matched RDF data originally from a specified content URI.
Rasqal ships with triple store implementations using the output of an RDF parser from Raptor and over a Redland indexed triple store.
These can be called using the standalone roqet query utility giving a query language identifier and query string to run the query over content described insidry stringry string (in RDQL, the FROM clause).
System Requirements:No special requirements.
