# What is DDL3?
DDL version 3 is the name given to some work in progress by Syd Hall and
his colleagues at the University of Western Australia. It is intended to
build on the greater consistency and data typing abilities of DDL2
without tying the data model too closely to that of a relational database. A
particular goal of DDL3 is to introduce methods into data dictionaries
through a formal language known as dREL (Dictionary Regular Expression
Language).
I've not seen a DDL3 example, but many cases can probably be covered with
what is in pdCIF already.
The application which does the plotting doesn't need to end up inside the
cif as part of the file, but the equation linking detector pixels to
Q could be very useful. There has been a good deal of effort already in
ImageCIF for single crystal experimental data.
I understood Maud can read and plot cifs already, and is written in Java?
Could there be a browser plugin version for this?
Best,
Jon

Now this sounds interesting. Certainly the raw data should be archived
and people could then plot it as they wish. But are there examples of
interactive plotting applications embedded in powderCIF files, and what
language might they use ? I would like to see a profile plotting package
in Java or some other really portable language that would read in CIF
files and plot calculated-observed patterns like Jmol now plots
structures.
