Setup metadata links from OBIS to CIOOS

[jeffcullis]

For physical/BGC data that is related to a biological dataset in OBIS, we need to determine a standard way of filling in the IPT / EML metadata so that it can link out from the OBIS dataset record to the associated CIOOS dataset and/or catalogue entry.

Copied over Sean's post relevant to this issue from Slack:

An example of a method to link external resources into the body of the EML of an OBIS file can be seen below. Note that this falls under the AdditionalMetadata tag as opposed to the Dataset tag where most EML dataset content is held. This typically gets listed at near the end of the EML file after the </dataset>

<additionalMetadata>
<metadata>
<gbif>
<dateStamp>2020-01-01T00:00:00Z</dateStamp>
<hierarchyLevel>dataset</hierarchyLevel>

</additionalMetadata>

Note that this EML may or may not be frankensteined together, so this does not represent a real-world example from an existing dataset.

Not sure if this's helpful but this is the additionalMetadata part of my eml.xml.j2

<additionalMetadata>
    <metadata>
      <gbif>
          {% if dataset_first_publication_date %}
          <dateStamp>{{ dataset_first_publication_date }}</dateStamp>
          {% else %}
          <dateStamp>{{ current_utc_dt }}</dateStamp>
          {% endif %}

It won't let me attach the j2 template raw, so here it is zipped. It's actually too hardcoded still, we're working on replacing more of it with the Jinja variables eml.xml.zip .
