Hi !
(note : not sure if this will be appended to the old thread at
http://sourceforge.net/p/virtuoso/mailman/message/32008220/)
Is there any news about the reference documentation of GI-related functions
in Virtuoso 7.1 ?
I didn't find anything yet.
If it's not ready, would it be possible in the meantime to have a plain
list of all available functions (even if not described, the function name
already gives some information) ? A draft of the doc would do as well...
I'm currently wondering if there are equivalents to Postgis' ST_Transform,
ST_Simplify and ST_AsGeoJSON...
Thanks !
Olivier
