This database is completely free (no payment or email address required). We at David Hobbs Consulting want to push the discussion of inventories forward, beyond simply the assumption of blindly slogging through spreadsheets, and this is a way we hope to accomplish that.
In a traditional inventory, each row represents a piece of content. Each row has different fields in it (such as File Format). Some fields are easier to gather than others, and some are more useful than others.
A disposition is a consistent manner of content during a transformation. Using them allows for planning for effective and efficient content improvements.
Currently there is only one article, How to do a content inventory or content audit.
