[ros-users] data storage for recognition

[Matei Ciocarlie]

Hi Ugo,

The database_interface package that you found is what we are using
internally for our database of objects for manipulation (also see the
household_objects_database package, which uses this interface).

A few weeks ago we had some discussion about database support going
forward; the decision was that for "low-level" database integration,
we might switch to an existing open-source tool (such as
http://soci.sourceforge.net/) instead of the current
database_interface. We have also identified the need for a
higher-level ros-sql conversion tool, to go between ros messages and
database entries. However, for the moment, no concrete plans for this
have been laid out.

For now, the database_interface is in use, documented, and I will be
glad to provide support if you decide to use that. However, in the
longer run, it might be replaced by other external tools.

Matei
