| 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). |
