Yes. In the action menu within a collection, there’s an option “CSV export - results metadata” which generates a CSV for download. This appears to include all fields on each asset - the schema is whatever you’ve configured for your instance of RS.
> 2. Is there a crosswalk between IPTC and Dublin Core?
Yes. Pardon a little pedantry, but it will help to be specific: IPTC is an organization that governs several different metadata standards. IPTC Core, which is the starting point for XMP-based IPTC metadata, has five fields which map cleanly to DC fields (Title, Subject/Keywords, Creator, Rights/Copyright Notice, Description).
Hope that helps,
