We are setting up a repository of definitions used in Open Geospatial Consortium web services, so that xlink references in Geography Markup Language documents resolve to something useful. In some cases the definitions will be structured using special syntax defined within GML (e.g. for coordinate reference systems). But in most cases the definitions are structured generically, so we propose to provide alternative representations in GML (which has a <Definition> element for this purpose) and in RDF/SKOS using the RDF/XML syntax. The intention is to support content negotiation using the http Accept: header. The mime-types are application/gml+xml and application/rdf+xml, respectively. In the short term these representations will be persisted as little XML documents in a file-system. But since all are still XML, I am wondering what is the recommended practice for the file suffix. I had proposed to structure the tree with a terminal directory corresponding to the terminal field in the URI, containing files called 'gml.xml' and 'rdf.xml'. For example, the URI http://www.opengis.net/def/objectType/ISO-19107/2003/GM_Polygon would be supported by these paths on the server def/objectType/ISO-1907/2003/GM_Polygon/gml.xml def/objectType/ISO-1907/2003/GM_Polygon/rdf.xml However, a colleague has questioned whether the naming convention is optimal. I'm interested to know of other opinions and experiences relating to this. -------------------------------------------------------- Simon Cox European Commission, Joint Research Centre, Institute for Environment and Sustainability, Spatial Data Infrastructures Unit, TP 262 Via E.
