    Nicholas,<br>
    <br>
    The design of the sitelog xml was before my time here but I have
    written other schemas and corresponding software representing our
    data.  I tend to make mine simpler (I agree completely with the
    multiple definitions and multiple namespaces complaints) - to use
    fewer schemas. <br>
    <br>
    The enumerations for this set of schemas for sitelogs haven't been
    maintained, but certainly need to be updated.<br>
    There should also be an automated process for updating the receiver
    and antenna types<br>
     (I have been doing this manually for our processing metadata schema
    set which is not really sustainable).<br>
    <br>
    We should add the omitted fields that you mentioned, but I would
    prefer to make all these changes at once, rather than piecemeal.<br>
    <br>
    Our processing metadata schema set is available at: <br>
    <a class="moz-txt-link-freetext" href="http://sopac.ucsd.edu/ns/geodesy/2014/">http://sopac.ucsd.edu/ns/geodesy/2014/</a><br>
    It does have more up-to-date enumerations(in listTypes.xsd).<br>
    This does not have all sitelog fields from the database, only those
    that are relevant to our processing.<br>
    <br>
    Do you have a link to your GeodesyML schema?<br>
