About this cohort

Selected domains whose continued public discoverability, authoritative communication or service accessibility has material community value beyond the organisation's own commercial interests.

Inclusion identifies why a domain is useful to observe through this curated lens. It does not imply that domains outside the cohort lack public value, and it is not a formal classification of public-interest infrastructure.

This is a descriptive cohort view. It does not rank or grade organisations.

  • Observed cohorts are curated public presentation groups, not complete sector-wide coverage.
  • Cohort summaries describe public domain-layer signals only and do not create ordered assessments.
  • Public presentation cohorts may be mapped from collection cohorts, inventory sectors, or explicit overlapping membership.
