Controlled Documents

The LSST DMS requirements and high level design are defined in a series of controlled documents. These describe the DMS as it is planned to be constructed and as it will exist prior to the Operations phase of the LSST project. 

...

Please see Requirements and Design Hierarchy for a map of these documents.

Internal Design Documents

The DM team maintains more detailed design and implementation notes on DMS components in Confluence. These pages are "living" and may change as the code evolves, although they should always remain compatible with the accepted baseline versions of the above controlled documents.
