Limitations:
Attribute names can only be up to 12
characters long. Longer names will be silently truncated. This may result in
non-unique column names, which will definitely cause problems later. Only
Integer, Real and String field types are supported. The various list and binary
field types cannot be created. The field width and precision are directly used
to establish storage size in the .dbf file. This means that strings longer than
the field width, or numbers that don't fit into the indicated field format will
suffer truncation.
Geography Markup Language (GML)
A file format for the Graphlet
system: GML supports attaching arbitrary information to graphs, nodes
and edges, and is therefore able to emulate almost every other format.

Limitations:
Only Integer, Real and String field types can be created. The various list and binary field types cannot be created. For String fields, the field width is used to establish storage size in the .dat file. This means that strings longer than the field width will be truncated.
Keyhole
Markup Language:
KML is a file format
used to display geographic data in an Earth browser, such as Google Earth,
Google Maps, and Google Maps for mobile. KML uses a tag-based structure with
nested elements and attributes and is based on the XML standard.
