Agenda:

Server managed and technical metadata properties overlap
1. Using separate properties lets you choose the properties you want to use, and update them in the normal ways (SPARQL Update, POSTing RDF)
2. Using server-managed properties limits which properties can be changed, but enables repository functionality: e.g., checking fixity against the checksum, setting response headers based on the mime type/file name, automatically calculating the file size, checksum, and creation/modification dates.
3. Feedback from Juliet Hardesty
label vs use properties
Date fields in EBUCore

Notes:

2. Take care of with: https://github.com/duraspace/pcdm/pull/7

3. User modifiable dates can be more flexible
