Wikipage http://www.mulgara.org/trac/wiki/Create talks about "graph type".
It lists:

   - http://mulgara.org/mulgara#Model
   This is the default triple store graph. Specifying this type is
   equivalent to omitting the type parameter.
   - http://mulgara.org/mulgara#ViewModel
   A view graph that represents a combined set of graphs. See the Views
   section for more information.
   - http://mulgara.org/mulgara#LuceneModel
   A full-text string index graph based on Lucene. All statements placed
   into a full-text graph must have a literal-valued object. Queries against a
   full-text graph result in a match if the object in the query constraint is
   similar to any stored statements, rather than needing to be identical. See
   the Full-Text Graphs section for more information.
   - http://mulgara.org/mulgara#XMLSchemaModel
   A datatyping graph that represents the property of orderedness that
   literals like dates and numbers possess. Datatyping graphs are used to
   constrain results to be above, below, or between specified dates or numbers.
   See the Datatyping Graphs section for more information.
   - http://mulgara.org/mulgara#TypeModel
   A nodetyping graph that represents the type the RDF nodes have in a
   graph. Nodetyping graphs are used to constrain results to be literals or URI
   references. See the Nodetyping Graphss section for more information.
   - http://mulgara.org/mulgara#FileSystemModel
   A filesystem graph that can be queried to return information about files
   and directories on filesystems. See the Filesystem Graph section for more
   information.
   - http://mulgara.org/mulgara#PrefixModel
   A graph containing virtual statement about the characters prefixing
   string literals, or URI references.

Aside from the fact that this text makes reference to other, non-existent
documentation, I find this thoroughly opaque.  Anybody care to explicate?
