A maintainer is a person assigned or self-assigned to a page, space or section of a wiki who accountably takes responsibility for the quality of some of the content. The role may include that of a:

• secretary, collecting information from comments and meetings into the wiki
• refactorer, collapsing redundancy and inserting organization into a wiki
• solicitor, encouraging input from community members
• architect, categorizing pages, creating 'project' and 'overview' pages, assigning meanings to labels

A maintainer understands the overall taxonomy of the wiki and offers suggestions for tags and labels but also offers template guidance and organizational structure to edited or newly contributed pages.

• WikiGnome, a similar positive role, but with less explicit accountability.
• Champion, the Wiki Champion often is the same person as its maintainer.
• WikiZenMaster, often the WikiZenMaster and its Maintainer are the same person.
• If the role of a Maintainer is misunderstood, it leads to PageOwnership
• OverOrganizer - an anti-pattern in which someone re-organizes a lot of content without first seeking consensus for the changes.
