For high speed access to internal information about views and view columns, DQL processing uses design data extracted from view notes. Currently this information will be stored in a new database, named GQFdsgn.cat.

It is created using new updall flags. It does not replicate and is solely used as a fast-path tool to access design data at runtime.

Here is some LotusScript code to add / update the design of a named Notes application to the catalog. The NSFDesignHarvest call is currently undocumented. Use it at your own risk.
