Minimally-Viable Records

PAGE CONTENTS 5 minute read.

Metadata in the UNT Libraries’ Digital Collections uses the UNTL format, which is a locally-qualified Dublin Core schema with twenty-one (21) possible fields. Within the metadata documentation for the Digital Collections, there is an underlying concept of a minimally-viable record, i.e., the minimum amount of information required for a record to be usable.

A record meets the criteria for a “minimally-viable record” if it has values for eight required fields, representing the lowest common denominator of a “complete” record within the Digital Collections. Each of these field values can easily be determined or assigned by looking at an item, or through administrative information (for collection and institution).

Although we encourage metadata creators to enter all known/applicable information in relevant fields, optional fields contain information which may not be available or appropriate for all items.

Required Fields

Field Qualifier Definition Repeatability Reason
Title Main Title The name given to the resource. Every item must have one (1) main title

Some records may have multiple title types		 Every digital object should have a name encompassing the whole resource.
Language   The language(s) of the intellectual content of the resource. Repeatable as necessary Assists in narrowing search results and finding appropriate items.

There is an option for "No Language" to satisfy the requirement.
Description Content Description of the content attributes of the resource. Not repeatable Describes the item to assist users in finding relevant resources.
Subjects and Keywords [any] The subjects or topics that succinctly describe the content of the resource. A minimum of two subjects is required, there is currently no defined maximum Assists in locating items with similar topics, particularly for image-based items.
  University of North Texas Browse Subjects (UNTL-BS) A locally-defined hierarchical controlled vocabulary for subject description. At least one UNTL-BS term is required for all records in The Portal to Texas History These terms allow the "Browse by Subject" functionality.
Collection   Collection refers to a larger group of resources with a unique collective title to which the resource being described belongs. Items can be assigned to multiple collections as appropriate This is a primary way that items are grouped, topically, and provides a collection-level description for context.
Institution   A consistent reference to the institution or administrative unit that owns the digital resource for which metadata was created. Not repeatable Represents the partner institution that owns the physical collection and has the ability to confer usage permissions or provide copies.

Internally, the coded partner is also used for access to edit metadata records.
Resource Type   The type or category of the primary content of the resource. Not repeatable Important for browsing by material types.
Format   The digital manifestation of the resource. Not repeatable Used for metadata interoperability.
