ANNIS for dates

[gcelano]

I would like to specify the date of composition for each work in my corpus, which I am likely to represent as a range (a fictitious example: -120:-110). Ideally, users should be able to specify a range in their query in ANNIS, and be able to retrieve all works/tokens falling at least within part of that range (for example, -130:-115 should also retrieve -120:-110, because the latter partly falls within the former).

Are there corpora where the date issue has already been tackled? In any case, what would be the best strategy to express this kind of annotation in PAULA XML? Should one first identify one "chunck" for all tokens of a work and then attach the date annotation to it?
