A revision scheme is a sequence of major and minor revisions, such as A1 and B1, that are used while creating or revising a document to keep track of its progress as it undergoes change. This, in turn, also reflects any changes made to attached files that the document manages. All revisable documents in the revision scheme are composed of document masters, revisions, and versions along with any attached files.
Document master
A document master represents the top revision-independent information, such as the document title.
Document revision
A document revision contains revision-specific information. As a document is created and revised, new revisions are created and attached to the document master. In a single configuration, such as a plant or a project, there can be only one current revision and one working revision at one time.
Document version
A document version contains version-specific information. A version of a document can be made for each project in a plant. Files are attached to the document version.
