The registration-search criterion
As noted above, the Registry is a notice registry system. Only very minimal information is required
or permitted in order to effect a registration. One item of information that must be provided by a
registrant is the appropriate registration-search criterion. This comprises the data that are used as
key for archiving and retrieving the file containing a registration; it is the criterion under which the
registration data are stored in the data base of the Registry and the criterion through which data
are recovered through a Registry search. Accordingly, the criterion used to search the data base is
identical to the criterion used to in-put and store the registration data
