I've been giving some more thought to LADSPA 2 recently, and I've knocked up a quick editor for RDF/NTriples syntax plugin descriptions. The schema used is not a particularly clever one, I just rolled it as I was writing the code, and I'm not suggesting it for real use, its just to give a flavour of the format. http://plugin.org.uk/md-creator/ Runs in your browser (probably mozilla only - khtml may work) so requires no software installation - its all client side too. You need JavaScript turned on. Usage Add Plugin etc. create new form sections you can fill in Dump text shows a (crude and incomplete) description of the plugin Dump RDF dumps a machine readable description of the plugin Read RDF parses any RDF/NTriples data in the textfield and turns it into an ediable form. Example RDF/NTriples file: http://plugin.org.uk/md-creator/example.nt paste it into the textarea and click Read RDF to see it. Theres also a grpahical rendering of the example: http://plugin.org.uk/md-creator/example.png which may help explain it. The whole deal, UI, NTriples parser, RDF engine, NTriples serialiser is less than 600 lines of HTML+JavaScript (View/Page Source to read it), so I think that shows that this approach can be simple enough to implement. - Steve
