SFF Specifications
The following database provides access to SFF TWG published and draft documents. The following explains the fields of the database.
Date - The date on the latest version of the SFF document. If the document is published and there is no new draft available, this will be the date on the published document. If there is a new draft available, this date will represent the date of the latest draft.
ID - The document ID.
Title -The title of the document.
Status - Reflects the following for the most recent version of the document:
- Published - Documents that have been completed and approved for publication. The revision number listed for the published document will be linked to a copy of the latest published revision of the document.
