Agenda & Notes
- Subgroup reports
- Descriptive Working Group
- met on 11/18 - Descriptive Metadata Call 2015-11-18
- decided to wait on 2 main charges until a use case exists for each:
- best practices for handling controlled vocabularies
- best practices in handling blank nodes
- changed goal of building a metadata application profile to explaining how to build one
- the original goal was to be consistent with Hydra in a Box
- the default schema for Hydra in a Box is now the DPLA map
- no need to replicate this
- the focus is now explaining how to build an application profile based on layers
- UCSD can serve as a model for this
- layer 1 (lowest): Dublin Core
- layer 2: DPLA-consistent
- layer 3: local/custom layer
- this will be incorporated into the Dive into Hydra Works tutorial
- UCSD can serve as a model for this
- the original goal was to be consistent with Hydra in a Box
- Carolyn will update the wiki to reflect new goals
- we might revisit best practices for blank nodes in the future
- MODS and RDF Descriptive Metadata Subgroup
- Applied Linked Data Working Group
- no meeting since Metadata IG last met
- Segment of a File Working Group
- met on 11/30 - SoaF call 2015-11-30
- looked at image use cases
- Rob Sanderson clarified Open Annotation selectors documentation
- discussed purpose of OA Fragment Selectors
- clarification of SVG selector
- vector-based image use case vs. non-vector image use case
- different ways to call those segments of files
- discussed purpose of OA Fragment Selectors
- hoping to have a draft recommendation sent out to Google groups for feedback mid-December
- likely to finalize recommendation by middle of January after considering feedback
- Descriptive Working Group
- Issues/Questions
- none
- Review Metadata IG Requests and Priorities
- Feedback on blank node item and minting new URIs item
- best practices for handling blank nodes and nested attributes
- discussion about what should be done if there are blank nodes
- should they be Skolemized?
- we have work related to this with the RDF group in terms of MODS
- bringing MODS in with namespaces that don't create blank nodes
- we should check with Adam Wead and Hydra developers to get input on how or if blank nodes are being addressed
- see discussion on Fedora Tech List w/ subject "Fedora4 and blank nodes"
- it appears there is no definite answer at this point
- see discussion on Fedora Tech List w/ subject "Fedora4 and blank nodes"
- there's no use case, so it would be hard to make a best practice recommendation
- discussion about what should be done if there are blank nodes
- best practices for minting new URIs - referred to two issues:
- best practice for when to mint a new URI
- we were looking at controlled vocabularies when needed for a predicate vs object term, but that wasn't the original intent
- it's unclear what is meant that predicate vs object wasn't an issue
- are they talking about minting URIs for predicates or value lists? was this distinction made?
- hosting issue - what namespace to use
- we've recognized there are situations where predicates are needed and people aren't finding namespaces with the predicate they want to use
- people are creating local authorities that they want to host or create a controlled vocabulary for themselves, but don't have a way to host that vocabulary for object terms
- in both of these situations, people have been looking to opaquenamespace.org
- best practice for when to mint a new URI
- best practices for handling blank nodes and nested attributes
- Requests and Priorities page
- Julie will edit items where possible
- a back-burner category will be created for items that aren't actionable in the near future
- Feedback on blank node item and minting new URIs item
- Additional Items
- HMIG meeting schedule over holidays
- no meetings on 12/16 or 12/30
- Carolyn will facilitate the next meeting on 1/13/16
- Descriptive Metadata WG
- next meeting on 12/9 and meetings will resume on 1/6
- SoaF
- work near completion, so no meetings perhaps until January
- HMIG meeting schedule over holidays
5. Action Items
-Julie will edit request page
-Julie will check with Karen to determine distinction re: minting URIs and to see if Hydra Steering Group will address it
