To my surprise, my triplequerying algorithm is cited at the end of the documentation. Looking through the code, it’s not directly built on the sample code I provided. The implementation looks way cleaner, and has many more features beyond querying. I’m overjoyed to have had some part in this.

It spits out mysql insert statements ready for querying with my rdf sql query stuff.

The XSLT is taken from the rubyrdf distribution. The perl code uses XML::LibXML and XML::LibXSLT.

A perl and a PHP implementation is provided.
