Is your feature request related to a problem? Please describe.
I'm always frustrated when I want to know if a given annotation is found in another (well known) database and I have to look for it on my own

Describe the solution you'd like
Common identifiers being reported

Describe alternatives you've considered
Let it as it is now

Additional context
Use Wikidata to gather identifiers. Decide how to implement it (store them for some time or not, etc.)
