Change management documents produced by authoritative providers
Library of Congress
LOC currently implements Activity Stream and has types.ATOM feeds for each of its datasets. Examples:
- Subjects: http://id.loc.gov/authorities/subjects/feed/1
- Names: http://id.loc.gov/authorities/names/feed/1
- Organizations: http://id.loc.gov/vocabulary/organizations/feed/1
- ISO 639-2: http://id.loc.gov/vocabulary/iso639-2/feed/1
This provides information about whether and when resources have been created, updated, or deleted/deprecated.
LOC is in the process of implementing Activity Stream. This work will duplicate the information communicated with the current ATOM feeds, but will also permit LOC to offer more specific activity streams, such as one devoted solely to authoritative label changes. Some issues being considered:
- URI URI belongs to a scheme when active (e.g. subject scheme). This is identified by a triple. The scheme triple is removed when it is deprecated. Point is: Deprecation alters the resource in fundamental ways.
- Sometimes a term may move from one authority (e.g. subject) to another (e.g. genre). Adds a triple identifying the new term (e.g. use_instead predicate). Complicated when the change is a split. Which term's URI should be used for use_instead?
...
- . This makes redirection or advertisement of the 'replacement' URI easy. But sometimes a single term may be split into two or more. No longer a one-to-one replacement, it is unclear what a suitable replacement would be for the old URI.
