PHD

[Mike Chalenburg]

That makes sense from what I have seen up until now.  Do I understand
correctly that you are indicating that the same basic scheme will be in
version 8?  In other words will I be able to change the metadata and then
only have to recompile the screens that would be directly affected?

I had been given an indication from someone within Cognos Telesupport that
the whole dictionary scheme was going to change in version 8.  The
impression I got was the "5 file" dictionary was going away and that the PDL
compilation process was going to produce something with a very different
format.  That file or files would then be used at compile and/or run time
with the screens, etc.

There are two reasons for asking this.  One is to try to determine what
kinds of changes we are going to need to make in our procedures for
modifying the dictionary.  The other is that we have an in-house product
that reads the current dictionary.  I would like to be able to continue to
use this product and hence would like a general idea of whether that will be
an option.

Thanks.

Mike
