Metadata Operations Team – Dome metadata update project overview
To date there are eleven collections in Dome with a total of 63,784 items. As each collection was mapped into Dome, ad hoc decisions were made as to which metadata fields to use, what custom qualifiers to attach, and how these fields would be used within the scope of the collection. As the number of items and diversity of collections have grown, this has led to collections that are not always compatible with one another. An urgent need to update the metadata registry in Dome and establish sound metadata policies becomes more and more apparent with each new collection deposited in Dome.
Proposed updates to Dome metadata
- Standardize use of metadata in Dome (in process of drafting an application profile https://wikis-mit-edu.ezproxyberklee.flo.org/confluence/display/LIBMETADATA/DOMEMDRULES)
- Create new metadata registries (if necessary to meet the needs of specific collections, formats and genres)
- All new schema must meet specific criteria and be approved by MOT prior to being added to the registry
- Require all new items ingested into Dome meet these new standards
- Remapped existing Dome records to comply with the new standards
Potential benefits
- Shared vocabulary, definitions and metadata usage across all Dome collections
- Improve browse and search capabilities across collections
- Ability to manage format specific metadata
- Better positioned for future projects involving data migration, manipulation and visualization
Next Steps
- Dome Core (required and optional metadata) – approved by MCG 17 Aug 2010
- Analyzed the current use of metadata elements in Dome and established definitions and usages parameters for Dome Core elements (both required and optional)
- Draft a list of changes necessary to bring existing metadata in Dome into compliance with the Dome Core and the recommended registry changes
- Create new metadata registries in Dome
- vra, and other schemas as necessary to meet the needs of specific formats and genres (pbcore, mods, etc.)
- custommd/dometerms (name up for debate)
- new schema and namespace for local terms that do not fit into a standard recognized schema
- Take action in each contributing community to bring workflows into compliance with Dome Core Metadata Policies
- Determine what needs to be done to bring existing Dome records into compliance with new policies
