[Data-modeling] Databases

[Ed Laurent]

I added a bunch of new properties to
Database<http://www.freebase.com/tools/schema/user/spatialed/database/database>.
I'm trying not to go too crazy with it but there are lots of interesting
metadata out there that could be useful. ;)

I also added a Spatial
database<http://www.freebase.com/tools/schema/user/spatialed/database/spatial_database>co-type
that includes "Spatial extent" and "Temporal extent" properties.
This would probably differ from attribute tables of GIS layers. Thoughts?
There are FGDC geospatial metadata standards
<http://www.fgdc.gov/metadata>that would be appropriate to reference
when modeling those. My thinking
about the spatial database type is that it describes data that have spatial
references but are not spatial data layers (e.g., shapefiles, grids).

I anticipate starting up a Spatial Data Clearinghouse type (maybe a domain?)
to complement the Location domain soon.
