[fdo-users] FGF and ISO SQL/MM WKB

[Oyvind Idland]

Hi Orest,

thanks for your info.

We are currently developing a system at my place, where we use the SQL/MM
WKB as the internal
geometry protocol.

Oracle SDO do have support for SQL/MM  WKB/WKT (and also has adopted other
parts of the standard),
at least from version 11g.

I think there are some work done in PostGIS aswell.

A WKB-talking FDO would be perfect in our situation :)
