If we are voting here, I would say that any naming convention should
be avoided at all costs, as they tend to be rather arbitrary, and
easily manipulated.

I am also much against the unique name restriction currently imposed
in the data model. We have situations where there identially named
facilities within the same organizational unit (think of McDonalds
here). I think DHIS is even more restrictive that this example. I grew
up in Pickens County, Georgia. There is no reason why there cannot be,
or should not be identically named organization units. DHIS 1.4 gets
around this by the use of naming conventions, which causes me no end
of headaches when I have to produce a report. I suppose the same could
apply to other concepts, such as "Age".  They should be able to be
distinguished through other means.

 I am not sure if a UUID is the best way for this, as it does have
potential performance implications, but it is certainly preferably to
any naming convention that may be enforced through the UI and not the
DB.

Regards,
Jason
