Hi Peng,

I amusing the PhyloDB schma add-on for BioSQL to store trees, however the data model will also support reticulate networks.

The project is at an early stage with few uses so ample oppotunities to help develop.

hi, friends,
   I've noticed in oracle 11g/10g, they support network data model, which you could find here:Spatial Topology and Network Data Models Developer's Guide:http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11831/toc.htm.
   I wondered are there any related part in PostGIS or 3rh part open source project?
   Thanks!
peng
