The domain-centered approach to indexing is based on an interpretation of the domain analytic approach to information science suggested
indexing is that it explicitly bases the analysis of the document on analyses and understandings of the domain and the users.
This ensures that the analysis of the document's subject matter is placed within the domain's and users' discourse.
The contention is that the indexer should have an understanding of the users' and the domains' goals, purposes, and activities to make an assertion about a document's subject matter.
