Thanks Denny for the update and everybody else for the feedback.
The cases I am particularly interested in are those of qualifiers to express that "Elizabeth I was Queen of England between 1558 and 1603", or that "the city of Vibo Valentia was in the Province of Catanzaro up to 1996, in the Province of Vibo Valentia until 2014 and in the Province of Catanzaro-Crotone-Vibo Valentia after 2014".
Until these qualifiers become available, the only way to represent that a region has changed its governor is to overwrite the old value of "head of local government" with the current one.

Hi Dario,
two or three features are still missing to enable that (sorted in order we are probably going to deploy them):
- qualifiers
- the time datatype
- statement ranks
As soon as they are available, this can be modeled in a way that it can be useful for projects accessing the data.
So, progress yet, but it's not there yet :)
Cheers, Denny

Thanks Dario

Is there something like VALID_FROM and VALID_TO in your Database?

This is basically what the qualifiers do. http://meta.wikimedia.org/wiki/Wikidata/Notes/Data_model_primer has more details.
Hm, sorry I didn't remember this. Thank you for reminding!
