Issue BB-111 resulted in the addition of the ISNI field to the list of available identifiers for creators and other entities. However, unlike other kinds of identifiers, like VIAF, Wikidata, LibraryThing and OpenLibrary identifiers (among, presumably, others), which will be correctly populated even if a URL is copied into them, the ISNI field does not trim an ISNI URL of the form <http://www.isni.org/isni/0000000121016384> into the raw ISNI value "0000000121016384". The BookBrainz interface should support automatically trimming ISNI URLs as it does these other identifiers.
