Agenda & Notes
Subgroup reports
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
Carolyn will update the wiki to reflect new goals
we might revisit best practices for blank nodes in the future
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
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
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
there's no use case, so it would be hard to make a best practice recommendation
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
