Though this document explains the content of the elements, it is not the same as a user manual. It does not instruct you on how to operate a database or show sample screens. To understand how to use a system itself (paper or automated), you should consult the user manual for the application you are using.
A Work In Progress
Remember that the Lifecycle Data Requirements Guide is, and always will be, a work in progress. There will be changes to our descriptive practices as lifecycle systems are implemented and maintained, as we continue to accession new materials, and as our business practices improve. These changes will be reflected by creating new elements or deleting unneeded ones, by updating the definition, purpose, relationship, or guidance statements, and by continually maintaining the authority sources to keep them accurate and current.
