Metabolite annotation with InChI Key

[Midnighter]

Metabolites in BiGG, where available, are annotated with InChI Keys. That is super useful. Unfortunately, the keyword does not follow the Identifiers.org standard. It describes the namespace/collection/registry as inchi_key but it should be inchikey.

Here is an SBML example for pyruvate.
