My organization has fairly strict standards for metadata, particularly for any data that will be available to the public. We have some GIS layers stored in one of our initiatives (we have Hub premium, not just the open data portal) that we would like to associate with metadata that meets our organization's standards, which are based on the FGDC CSDGM. However, whenever we upload these layers to the Hub storage, the metadata is automatically converted to ISO 13139 format and drops a number of fields from the metadata. Of greatest concern to us is that attribute definitions aren't included, which we consider essential for anything that may be used by people outside our organization.
As a test, I tried uploading metadata in ISO 13139 format, and I got similar results. The resulting metadata was cleaner than what had been converted from FGDC format (the converted-from-FGDC metadata had some fields, such as tags, included multiple times in the XML), but it still clipped off the attribute definitions.
Whether we upload in FGDC or ISO format, the metadata cannot be edited once in the Hub storage. Clicking the Metadata button on the Item Description page opens a static page showing the metadata in a browser window instead of opening the metadata editor as expected.
Is there a way to have full control over the metadata associated with items in Hub initiatives, as there is with normal AGO items? If so, how do I do it?
