Description of Document: This document presents a proposal from the NISO Metasearch Initiative Task Group 2 for a new class/encoding scheme, SubjectCompleteness.

Proposal

Name SubjectCompletenessIndicator
Label Subject Completeness Indicator
Definition A Subject Completeness Indicator provides a measure of the depth of a collection in relation to a specified subject area.
Comment

A Subject Completeness Indicator specifies:

  • a subject, which must be from a recognised subject scheme
  • a level of completeness, which should be from a recognised scheme, such as a Conspectus Level
Examples

Subject: [LCSH] Finland

Level of Completeness: [Conspectus Level] 5

(Proposed property) subjectCompleteness

Why needed

The use of a structured SubjectCompletenessIndicator value for the subjectCompleteness property enables applications to perform operations such as searching for descriptions of collections according to specified completeness levels in a specified subject area.

Evaluation of collections has suffered from some level of subjectivity, but practice and general guidelines will make the collection descriptions more consistent.
