By this description alone it seems to me that OpenURL, perhaps
implemented as some variation on COinS, would make the most sense.
With OpenURL, the fields have already been defined. Perhaps the
underlying JSON for the annotation could look something like the
following:

{ 'annotations':
  { 'z3988':
    { 'contextobject':
'ctx_ver=Z39.88-2004&amp;rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&amp;rft.issn=1045-4438'}
  }
}

Additionally, one could specify an optional resolver parameter if so desired.
