Hi Rob,

nd/or libraries for spatial representation and calculation?

Yep this is exactly what I was asking. The goal of SIS is to provide such a=
 library, in an ALv2
licensed fashion:

I was thinking if the spatial part of Parliament was pluggable, we could us=
e SIS to implement that part.
Right now, I will likely start looking at parts of Jena, Any23, and Tika th=
at are relevant.

Note, I'm also doing some stuff in OODT-ville through GSoC (see OODT-402 [1=
]) that is connecting stores like OODT
to SIS, and looking to do something similar here.

Cheers,
Chris
