Notes:

Status of Predicate Decision Tree doc (https://docs.google.com/document/d/1oMvVlGuBwD5U1251oxNmTZn7WgkNTj6tF-k1hOYjnac/edit?usp=sharing)
- Workflow/status of object - no namespace exists that we know of so predicate will need to be generated, removing from decision tree
- PREMIS - Fedora already uses PREMIS to track events
  - Might be some difficulties using PROV-O and PREMIS but unsure of complications
  - Controlled Vocab Manager behind opaquenamespace - stores as something else and then produces PROV-O triples
- List PREMIS and PROV-O for preservation
- Controlled vocab decision tree would be similar steps but with different ontologies; priority to get out predicate decision tree
- Added recommendation to check domain
Survey results analysis - 18 responses
- Responses only from Hydra and Other repository software users (no Islandora responses)
- Don’t have to support versions (only 1 response used previous version of an ontology)
- Still not sure about controlled vocab/values support (4 responses looking for objects/controlled vocabs/values and couldn't find them)
- Most literals are strings but also majority responses storing date/time, numeric, and strings with language code
- Everyone reports storing literals but only some are also storing URIs (no one is only storing URIs)
Functional requirements for Hydra Vocab Manager - next steps
- XML schema that needs to be RDF: GeoRSS as RDF
  - Predicates from this, but not sure about controlled vocab
  - Might need bounding box as object but could be a domain (currently type attribute in XML)
  - Could mean need to support classes
- PBCore descriptive metadata maps pretty well to EBUCore - still working on structural but experimenting mapping to PCDM now (directly in Fedora 4)
- Start google doc for functional requirements
  - Section for use cases
  - Section for requirements to meet those use cases
  - Section to define phases of development
Hydra Connect - what does this WG need?
- Ask about lightning talk to report out
- No need for meeting time
