Editing IBM DevOps Code ClearCase (section)

== The configuration specification ==

Under base ClearCase, each view is controlled by its associated ''configuration specification'', commonly referred to as a ''config spec''. This is a [[Domain-specific programming language|collection of rules]] (stored internally in a text file, but compiled before use) that specifies what element versions (files or directories) are to be displayed in a view. To determine which version, if any, of an element should be visible, ClearCase traverses the configuration specification line-by-line from top to bottom, stopping when a match is found and ignoring any subsequent rules. A configuration specification can also reference other configuration specifications by means of an 'include' statement.

In the UCM management model, config specs do not need to be created or maintained manually: they are generated and maintained by ClearCase UCM operations.
