    Hi Chris and all - <br>
    <br>
    I'm very interested in these new identity terms, which we would like
    to <br>
    add to the OceanSITES netCDF specification; the OS spec is built on
    CF <br>
    and ACDD 1.2. <br>
    <br>
    <blockquote type="cite">the need to include identifiers (ORCID,
      ResearchID, AuthorID, etc) for the person listed in the creator
      attributes and the people listed in the contributor attributes. </blockquote>
    <br>
    We use the ACDD terms, creator_*, publisher_*, contributer_*, (where<br>
    the * is name, email, url, etc) and our current manual adds the
    modifier<br>
    _orcid - at least to the publisher field (not sure why the others
    seem to <br>
    be missing, I'll look into that).  <br>
    From the manual:<br>

    <br>
       <br>
    In reviewing some of my files, though, I see I've also used<br>
    creator_id = <a class="moz-txt-link-rfc2396E" href="https://orcid.org/0000-0001-8001-6886">"https://orcid.org/0000-0001-8001-6886"</a> ;     <br>
    <br>
    I think that's actually better, because it allows different ID<br>
    types. There is a group working on a system similar to ORCID<br>
    that will identify groups - I'd like to see a persistent identifier
    for<br>
    the research group I work in, because I think our data needs to be <br>
    tracked back to the group, more than to any individual. At some
    point<br>
    we may supply the group name as the publisher, and it would be good
    to <br>
    have a PID for that. <br>
    <br>
    Also, I've been looking for the definitions of the roles we used in<br>
    ACDD. I still believe these definitions can be improved upon, (eg: <br>
    'creator: the person who created the data') but since they're just
    referred <br>
    to as ISO roles, it's hard to find them these years later.<br>
    <br>
    I disagree with Bob Simon on the problems that arise if we change
    definitions. <br>
    If you trust a data writer when he says a file uses ACDD, why on
    earth wouldn't<br>
    you trust him to also document the version? A simple work around, of
    course, <br>
    is to ditch the terms we use for roles, and make new, improved ones.
    It can<br>
    still be ACDD. <br>
    <br>
    <br>
    Last item -  does anyone think ACDD could be moved to the Discovery
    cluster? <br>
    At least in theory, it was originally all about discovery.<br>
    <br>

                            <div class="">Short answer is that (as I

                              'managed' by the ESIP Documentation
                              Cluster, and to start the process of
                              adding an attribute to those conventions
                              you would make the request to that
                              cluster. It's my hope that the cluster
                              would relatively quickly form a team and
                              process to support the request. They*
                              would not necessarily have to discuss any
                              other change, and other than formalizing
                              what process they want to follow, it could
                              be quite quick to decide. (Posting updated
                              documents might take longer!)  It could be
                              a valuable exercise for the Documentation
                              Cluster and community, in my humble
                              opinion.</div>
                            <div class=""><br class="">

                            <div class="">When you say "an attribute

                              are right that ACDD allowed this use but
                              purposefully left it ambiguous in the
                              creator_url. At some point, if you want to
                              make ACDD less ambiguous, the amount of
                              duplicate content starts going up because
                              of backward-compatibility requirements,
                              and maybe you want a new path that's

                                        the ACDD 1.3 conventions. It's
                                        providing more explicit guidance
                                        as to how the IOOS community
                                        should use it (maybe the

                                                          (1) At the

                                                          least one

                                                          existing ACDD
                                                          attributes

                                                          followed a
                                                          previous
                                                          version. So
                                                          our ability to
                                                          update certain
                                                          fields the way

                                                          With ESIP's
                                                          Documentation
Cluster(Committee?) as the current 'standards body' for ACDD, you'd be

                                                          another round,
                                                          especially if

                                                          would open up
                                                          quite a number
                                                          of questions
                                                          that just
                                                          might go
