1.    About rdftp

 

rdftp is an RDF server that supports Query and Update operations on RDF content. The purpose of rdftp is to be an experimental implementation of an RDF Transmission Protocol. 

 

The rdftp server stores RDF content both in a relational database as RDF triples and in a hierarchical repository of RDF graphs/models, residing in the server’s filesystem as RDF files.

 

The rdftp server is implemented[1] as a PHP script and runs on top of any HTTP server that supports PHP. Both Query and Update operations[2] can be called using either HTTP GET or HTTP POST. rdftp also provides a simple HTML interface for “Navigating” through the Query results that are presented as Triples in a tabular form.

 

rdftp stores RDF data in a relational database as triples using a single-table approach. Apart from the triple itself, the table also contains information about the source model /graph of the triple.

 

This is the initial version (v. 0.5) of rdftp RDF Server. rdftp is available under the GNU/GPL license. Documentation and user guide is included in the Download.
