README for RDF-RDFa-Template ---------------------------- This module is the beginning of a suggested simple RDFa-like templating language. It is not intended to be RDFa, it is intended to give template writers something that they are familiar with from the XML world, yet they can use an largely unmodified XML-based RDFa-parser to do the parsing. In this case, RDF::RDFa::Parser is used. For more information about the design of this templating language, see http://www.kjetil.kjernsmo.net/software/rat/ BEWARE OF TODO-LIST: This is an initial release just to enable a meaningful discussion. Thus, there are many remaining tasks before this is a fully functional templating system. If you start experimenting with writing templates based on this module, it is important that you read the TODO list in the POD of RDF::RDFa::Template. The proper forum for discussing implementation details of this module is this mailing list: http://lists.perlrdf.org/listinfo/dev or the IRC channel irc://irc.perl.org#perlrdf NON-CPAN DEPENDENCIES: You need libxml2, including header files, of at least 2.6.27 for canonicalisation to work properly, and this dependency is something CPAN will not bring along, so you will need to get it from your software distribution or http://xmlsoft.org/ . On some distributions, this package will be called libxml2-dev og libxml2-devel. RUNNING EXAMPLES: The distribution contains a script that sets up a very simple web server that can do the transformation and show the results. Where this script ends up depend on your installation method. If you have used cpanmin.us (cpanm) as a non-root user on UNIX-like system, you will probably find it in a directory looking like ~/.cpanm/work/some.numbers/RDF-RDFa-Template-version/examples Another way to find is to use the locate command if it is installed on your system and access to update its index, you can run sudo updatedb locate dbpedia-mustang-range.input.xhtml cd to this directory. In there, there is a script called demoserver.pl. Again, if you used cpanmin.us as non-root, you will probably do something like perl -I$HOME/perl5/lib/perl5/ ./demoserver.pl If everything goes well, you will see a message saying: "You can connect to your server at http://localhost:8080/" Any template files in this directory can now be visited by a browser, and the script will run the template and perform SPARQL queries to insert values. For now, there is only one example, see http://localhost:8080/dbpedia-mustang-range.input.xhtml The demoserver.pl script itself is a nice illustration on how to set up a server to use the templating system.
