I'm assuming you want these in XML format or somesuch?
There are a couple of options.
If you are using Control-M Enterprise Manager at your site you can use the EM utilities such as "emdef exportdeftable".
You can also use the Automation API which effectively runs the same utility.
If you want to run the extract from your mainframe you can use the CTMTLB utility.
Please let me know if you want more assistance with either of these utilities.
