Re: [Tracker] Does tracker support uniquie object-id across databases

yes, we decided to use 32 bit integer as an object-id due to resource-constrained environment, but if i add a predicate for this purpose then i think i'll have to modify each & every extractor available in tracker to insert/query this custom object-id?

I'm not totally sure I understand your message... Do you need 32 bit
integers, or are you saying that Tracker's uuids are not robust enough
Tracker urn are of the form
which is more than 32 bits if I'm right. If you need a 32 bit integer
identifier, then you can add a predicate to the resources you need to
share, with the 32 bit integer inside.
