Probably a silly question but ... did you all consider creating a datatype for molecue representation ? This seem to be a very similar usecase than mathematica formula. Essentially we're not dealing with a raw string but a representation of molecule formulas, with its own encoding ...

Changing the limit seem to be a poor workaround to a dedicated datatype - nobody seems to have found a relevant usecase and it seem to me that we're essentially abusing strings for storing blobs ...

External identifier then. Cool. And for string like in
https://www.wikidata.org/wiki/Property:P233? Sebastian's initial email 
says 1500 to 2000. Is this still a good number after this discussion?

Yes, that would cover more than 99.9% of all InChIs in PubChem. (See Sebastian's reply earlier in this thread.)
