Metadata contact information in schema.org

[smrgeoinfo]

It would be a good thing to have metadata contact information in the metadata record, providing an e-mail for notifying the metadata responsible party about problems in metadata contact. This comes up when I run a search and get metadata records with broken links, no information, or obvious errors and I want to notify the metadata curator about the problem. There's no obvious way to shoe horn this into schema.org at this point.
