Ur-Core Statement of Principles (DRAFT)
The members of the DOME metadata strike force were charged to review and document the current metadata conventions for digital libraries, and to develop a set of recommend standards and guidelines to govern future metadata creation within DOME. The outcome of this research will be a core set of elements for each type of object (audio, video, etc.) that may one day be deposited into DOME. In addition, the strike force developed Ur-Core, a common set of elements that all objects require, regardless of type, collection, or project. We recommend that it be mandatory for all digital objects being deposited into DOME to have the proper metadata to fulfill the needs of this common element set.
Objectives for an Ur-Core Element Set
- To mediate translation from one metadata standard to another and from one system to another
- To govern the aggregation of different kinds of metadata in the same systems.
- To enable the archiving and preservation of digital objects through their lifecycle.
- To ensure a consistent, high level of quality metadata across collections
We recognize that these elements could describe either:
- The intellectual content of the information resource
- A physical object containing the intellectual content
- A digital object containing the intellectual content
The Ur-Core elements describe the intellectual content of the information resource. In describing the intellectual content we will sometimes describe the content as an object (when was the content created, where, by whom), and other times analyze the subject of the content (date of a performance advertised in a broadsheet, a place described by a travel book, or a person that is the subject of a portrait). In selecting Ur-Core elements we attempt to describe the object. Only the “Name” and “Notes” fields describe the subject.

Ur-Core Element |
Definition |
Identifier |
A globally unique, persistent name/code/uri for the resource. |
Rights |
Information about the copyright status and the rights holder for the resource. |
Name |
The title or identifying phrase given to the resource. May be title proper, statement of identification, or a brief description. |
Agent |
Name of the primary agent (person, corporate body, group, institution, organization) responsible for the creation of the content of the resource. |
Date |
Date or date range associated with the creation of the content of the resource. |
Type |
The genre or format/medium of the content of the resource. |
Notes |
A brief free-text note or descriptive statement that characterizes more fully than the title the scope or content of the resource. |
*Type in DSpace - Archival material, Article, Conference Proceeding, Book, Book chapter, Dataset, Image, Learning Object, Other, Plan or blueprint, Preprint, Presentation, Recording, acoustical, Software, Technical Report, Thesis, Video, Working Paper

Other Elements Considered for Ur-Core
Many elements discussed by the task force did not qualify as core elements. Each of the elements below may be very important to a specific collection, project, or item, and should be included in the metadata of an object, when needed.
- Access restrictions: Information about restrictions imposed on access and use of a resource
- Relationships: Aggregation; Peer-to-peer
- Subject Analysis: Dates associated with what is depicted in the content of the resource; People and locations associated with the resource (depicted/described/created); Additional Agents; Topics
- Language
- Descriptions of the physical and digital versions of the resource: The location depicted in the physical resource
- Dimensions
- Format
- Provenance: Source
- Custodianship: Name of the owning institution and/or the institution responsible for providing access to the resource
