This is not automatically built or installed at present since this interface may not be required. You can easily build it by hand as follows
cd tcl make build-tcl make test-tcl # optional
To install it system wide (this is optional) do this as root:
root# make install-tcl
The Tcl interface has been tested with Tcl 8.0.5, 8.3 and is alpha quality - the test and examples work.
The Tcl API is an object-based API with the class names and method names flattened into Tcl procedure names like this: librdf_class_method - the same names as in the underlying C API. The object references become Tcl variables.
The example program provided parses an RDF/XML source file into a model. It should be run with two arguments - the URI of the content (as file:/path/to/content) and the parser name (say, raptor):
tcl example.tcl file:../perl/dc.rdf raptor
NOTE: ONLY file: URIs work at present.
Tools written in Extended Object Tcl (XOTcl):
xoRDF developed by Gustaf Neumann (University of Vienna, Austria) and Uwe Zdun (University of Essen, Germany) as part of the ActiWeb framework (X11-style open source license). xoRDF uses either the XML parser written in Tcl from TclXML (free for non-commercial use) or expat.
There is an online demonstration of the parser available. Another sample xoRDF application was developed for the ongoing UNIVERSAL project (funded by EU IST) targeting a "brokerage platform for learning resources", which processes RDF based metadata of learning resources and presents it in a a user friedly way (source).
