DCAT-US 3.0 Technical Implementation FAQ

Question Short Answer
Is the DCAT-US 3.0 harvester stable enough to test against, or should we wait for production? Core support has landed with no known open defects; test against a test harvest source.
What's the difference between accessRestriction, useRestriction, and accessRights, and what values go in them? accessRestriction/useRestriction give structured who-can-access/what-they-can-do detail on a Distribution; accessRights is the plain-text alternative.
How are publisher and subOrganizationOf used within the data.gov catalog? Not used for filtering/grouping — org faceting is driven by the harvest source's owning organization. The top level publisher information shows up at the top of the dataset details page.
How will subOrganizationOf be displayed on Data.gov? Not displayed on dataset detail pages main UI — only publisher.name is shown. Full content is seen at the bottom under "Complete Metadata" section.
Can accrualPeriodicity mix ISO 8601, ISO 19115, and Dublin Core vocabularies? Yes, chosen per dataset not per feed; ISO 8601 also supports decimals (e.g. R/P1.5M for 8x/year).
