Thank you for the detailed explanation! I thought that it might be that 
way...

If I understood correctly, the AcoustIDs itself are stored on 
Acoustid.org server externally.
Are there any references from Musicbrainz tables (e.g. a GUID) to the 
data on Acoustid.org, or are they link all from AcoustID.org back to 
Musicbrainz (so that the AcoustId.org API need to be called in order to 
display which fingerprints are assigned to a recording for display on 
the Musicbrainz webpage)? I didn't found any reference for it in the 
CreateTables.sql script...

Thanks in forward for your answer!

Best regards,

Andre
