What exactly do you need? I think that the Jena API fulfills most stuff 
the Spaces did, for now. (Tuukka has suggested creating our own 
interface on top of Jena, but if we do that, the change shouldn't be big 
for you.) So what's keeping you from starting right now? :-)

I've noticed that Ideagraph uses the properties

    http://ideagraph.org/xmlns/idea/graphic#x
    http://ideagraph.org/xmlns/idea/graphic#y
    http://ideagraph.org/xmlns/idea/graphic#width
    http://ideagraph.org/xmlns/idea/graphic#height

to layout RDF nodes spatially. These have as subject the node to be 
placed on the screen, and as object a literal containing the position as 
an integer value (e.g., '71' or '126'). I cannot find a formal 
definition of these properties, but it may make sense to contact Danny 
Ayers <address@hidden>, the author of ideagraph, and work 
something out. More power to interop.
