Ability to specify primary or alternate metadata source #308
Description
In most cases the data.json file is the only available public representation of the metadata for a record, but there are some instances where there's already a well established version of this metadata that would make sense to designate as the primary source. This would frequently be applicable for geospatial data that already has a well established and robust representation of its metadata.
There's a great benefit to the data.json file providing a comprehensive and unified view of all records for an agency, but it's also worth recognizing that there will be situations where it's not of providing the best or most complete metadata for a particular kind of dataset. In these cases it would be great if the data.json was able to reference those other metadata sources.
perhaps something like:
"metadata_sources": [
{
"primary": true,
"source": "http://gis.agency.gov/metadata/",
"source_type": "waf",
"schema": "ISO-19139"
}
]
