After entering the information about your music into Rainbow Builder, you will be given a machine-readable RDF file, which you must save to your hard drive and publish on the world wide web.
It is best to post the file in unmodified form on a web server, along with the music that it describes. Advanced users may wish to embed it in a larger HTML file within comment tags. This use is supported, but you should be aware that embedding multiple RDF files within the same HTML page is not permitted.
Also, it is necessary that the xml:base attribute corresponds to the location where the file is published on the world wide web. Rainbow Builder will take care of this for you, as long as you enter the correct target URL.
We are working to fully document our RDF specification and to provide schemas for it. If you are interested in helping us, please let us know. If you have any other questions, please contact the gnomoradio-artists mailing list.
