Out of scope: Free text tagging. Development of shared controlled vocabularies for tags (though likely this would be wanted to cross-institutional librarian use). Dynamic tagging via a query that selects a set of items every time it is run (Note that Cornell CuLLR does use dynamic selectors but there are run only periodically as opposed to each time the curated list is used).
Potential Demonstrations
A. Selection of items for a virtual library which then appears in a centralized discovery interface: Subject librarians select a items to tag individually and through queries available in the discovery interface (such as subject classification range, bibid range). They tag items with a tag meaning “included in university X, virtual library Y”. The tag information is stored as LD separately from the catalog records by refer to them by URI. The discovery system integrates this tag information in its indexing process and produces a search facet for “virtual library Y”.
B. Engineering librarians build virtual reference shelf: In moving from a physical engineering library to a virtual library the engineering librarians decide to replicate online the popular shelf of key engineering reference handbooks that used to in the physical engineering library. In collaboration with the team providing their local discovery and access system, they decide on a tag that will be used to create an "Engineering Handbooks" facet. Tags are internally represented as URIs though the UI will likely show a human readable string. As the different librarians are specialists in different subject areas they decide to work together to tag items in their respective areas. One librarian creates the tag. They each then tag items from the catalog. These tags are then used in the local discovery and access system to populate the "Engineering Handbooks" facet.
Data Sources
- Catalog records
- Metadata for any other collections from which items are to be selected
- Librarian<->library relationships (perhaps including editing permissions information)
Ontology Requirements
- Ability to add contextualized tag information to items. Assume that all tags will resources (with label) rather than simply free-text and use OAC.
Engineering Work
- Authentication as librarian or other user allowed to create/edit tags. It should be possible for one of a set of librarians to apply a tag in a given context (e.g. all Engineering librarians at an institution can add certain tags for the Engineering library)
- Support for controlled vocabularies of tags
- Ability to tag item from remote system
- Bulk selection method to support selection by resource characteristics (could be "select all" for a set of search results)
- Ability for local system to understand provenance of tags so that only locally added tags are used to select items in the local virtual library (for example)
- Need URI for each tag that provides machine readable (and perhaps human readable via conneg) data for integration into other systems
- Means for selection and manipulation of tag data to feed into discovery environment alongside MARC record or other controlled data (what happens to tags for remote items?)
- UI will require a way to support selection by resource characteristics rather than individual items (could be "select all" and/or “check boxes” for a set of search results). This doesn’t create any additional model requirements.
