The client is nearing completion. I'm working on create, update, and Delete. I'll post a version of the file on this site when done
Thanks for the help from Sesame's project leader in the following forum thread.

I've successfully built an HTTP client using the Zend Platform against Sesame 2.0. Phesame was a very similar project which used PEAR and was only compatible with Sesame 1.x.
Sesame returns JSON it appears, and the Zend platform has a nice decode which works well for that. Still todo is complete SPARQL HTTP POST, and see if the SeRQL has the ORDER BY I need that Sesame doesn't support in SPARQL.
