Lydia and Wikidatans,
If we consider atoms and nano-related entities, and other similar different scale entities, will Wikidata string data types wish for more space in char limits, I wonder (and for anticipating data for a realistic virtual earth/universe at a) street view, b) neuronal/cellular c) molecular, d) nano/atomic levels, etc.)?

Dear Thomas,

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 ...
The InChI is actually not a structural representation, but a derived unique identifier.
What you propose would, however, apply to the SMILES. That one is generally of about the same size as the InChI, and there your solution sounds like a great idea!

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 ...

Ah, those numbers are for https://www.wikidata.org/wiki/Property:P234

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.)
