I've added support for name authority records from the OCLC LAF (Linked Authority File) [1] version of the LC's name file. These follow OCLC's convention of formatting the LC identifiers using this regex:

  'LAF'   : r'(n[0-9]+-[0-9]+)'

(I'm not 100% certain that's correct but will fix if i find out otherwise.)

OCLC's HTML page for a name record is supported as format "html", along with "marcxml".

Updated opa.py is attached. See older posts on OPA [2] for more details about running it.
