many thanks for your effort in this area. I hope having an XML format will make it easier to interoperate with other XML based formats, such as Collada. At the very least it should be possible to write converters with standard XML tools. Have you thought of using XML namespaces at all? So your example above would become: <osg:Geode xmlns:osg="http://www.openscenegraph.org/schemas/osg";> or something along these lines. That way, one could even conceive mixing OSG xml data with say metadata from other xml namespaces. Of course, namespace declarations can either occur on the xml tag itself (as shown above) or once per file (on the xml root element). > > To quickly get an XML file: > # ./osgconv cow.osg cow.osgx > > The StreamOperator header, InputStreram and OutputStream classes are > modified to be more portable for triple ascii/binary/XML formats.
