Hi Fabio,

Unfortunately, I have not had the capacity to follow the OpenGeoBI, though I
do find it interesting, as I do GeoMondrian. I suppose that for now, we have
settled on our own approach to aggregation rather than relying on a full
OLAP engine - partly because we found it less than straightforward to handle
complex indicator calculations.

We are also revamping our full dimensional model in DHIS2, and work remains.
As I see it currently, the basic  DHIS2 model should probably have time and
space as the basic, compulsory dimensions (the when and where), and then
requiring at least one more (the what, which we have been calling data
element), but allowing any number of user defined additional ones (typical
ones will be gender and age groups for disease type data).

All that being said, there is also intense  work underway, lead by Bob
Jolliffe, on developing the first version of the SDMX-HD standard (see
sdmx-hd.org). SDMX is closely related to the OLAP world, and does have an
apparatus for handling geographical hierarchies.
