Incomplete or under active development.

PUBLIC RECORDS
Significant theory, software, policy, design and research work should be assigned a reference, dated, versioned and preserved. Where a correction is substantive, the prior version should remain identifiable rather than silently disappearing.
Incomplete or under active development.
Published so the development can be inspected.
Replaced by a later version but retained for chronology.
No longer relied upon because evidence or review changed the position.
