Use Cases

Cache of Full Download

The application takes a full download of the authoritative data and stores it in a local cache.  Access to the authoritative data is made through the cache.

Options for update:

  • Re-download and cache the entire set of authoritative data.  This does not identify what has changed.
  • Incremental downloads and update of the cache of just the data that has changed.



Cache of Labels in an Application

When the application makes a connection to authoritative data, the label is cached along with the URI to allow for quick display of the label in the UI.

Options for update:

  • Periodic query of the authoritative data source to determine if the label has changed.
  • Watch an incremental feed of changes to the data and update the cached data for any that are cached in the application.
  • How to handle outliers that do not fit the expected types of changes?
  • How to handle a change that no longer applies?  Ex. When MeSH changes, even if the labels are similar, the old label is deprecated (gone) and a replacement label is created. In the past, identifiers were reused, which complicates the process.

On the provider side:




Entire Authoritative record in MARC records

  • caching label and URIs in MARC records; want to keep up to date and in sync; caching entire authority record in sync


Receiving data on New Entities and Deleted Entities


Cache of data in Sinopia; What happens with conversions from BibFrame to MARC and vice versa.

  • Data sync questions
  • Workflow
  • Heading toward data in triples instead of MARC
  • Data integrity and data consistency 


Local Data

  • creating data locally until it can be included in the authoritative data
  • in some cases, this is necessary
    • taking structured data from institutions and converting to RDF
    • creating URIs for manuscripts; want to link to other authoritative data when possible
  • many are trying to move away from this


Question:

  • What makes data authoritative?
    • When would the data be considered authoritative?
    • When is it considered local?
  • Would it become authoritative data if an entity moves from local use to a shared location like ShareVDE?
  • When additional local data is added to existing authoritative data and collected in a way that adds meaning, is this authoritative data?
    • Any work done outside of upstream, there needs to be agreement on what this means and how it will be applied upstream.





  • No labels
