This standard is continuously maintained by the Z39.7 Standing Committee. Continuous maintenance is defined as the maintenance of a standard by consideration of recommended changes to any part of it according to a documented schedule for consideration and action by the consensus body.
Comments or proposals for revisions to any part of the standard may be submitted in writing (including electronically) to NISO at any time, using the online contact form or by e-mail. Submissions must be accompanied by the submitter's name, affiliation, and e-mail address.
All submittals received by NISO are acknowledged and forwarded to the Z39.7 Standing Committee for consideration. The Standing Committee will schedule meetings via teleconference or in person when a substantive number of comments for review have been received, but in any case no less frequently than quarterly if there are unaddressed comments, with meetings to be set no later than March 1, June 1, September 1, and December 1, each year. The Standing Committee will inform submitters of the disposition of their substantive proposals within one month following each meeting.
When a sufficient number of changes have been approved by the Z39.7 Standing Committee, a revision of the standard will be presented to the Business Information Topic Committee for ballot approval and then to the NISO consensus body for publication approval. A new edition of the standard shall occur within five years of the prior publication date. If no revisions have been identified by four years after publicatin of the current edition, a reaffirmation process will be initiated.
See the Z39.7 Continous Maintenance procedures document for the detailed procedure.
