A directory accepts submissions, but nobody owns review or later corrections. Over time, duplicates and outdated details make it harder for visitors to find something useful.
Define the listing standard
Choose the information a visitor needs to decide whether a listing is relevant. State which claims require evidence and who can approve them. The site should distinguish submitted information from facts you have actually checked.
Plan duplicate review, category choices and the treatment of missing details. A large number of listings is not a substitute for usefulness.
Include maintenance
Give owners or staff a way to request corrections and report a closed or misleading listing. Decide how changes are reviewed and how the history is retained.
Test a new submission, a duplicate candidate, a rejected claim and an update to an existing listing. Check what appears publicly at each step and whether unapproved content remains private.
Bring the audience, listing criteria and maintenance owner to the project discussion. A useful directory is a publishing and data-quality process as well as a search interface, and those responsibilities should be included in the scope from the beginning.
Review search results as well as listing pages. A listing may be accurate but difficult to find if categories or location fields are applied inconsistently across submissions.
