I would like to be able to define (or edit) the CPE for CVEs. I would suggest the editing allow you to either directly enter the CPE OR provide a helper that lets you fill out the information per the CPE specification, with unknown fields being '*'.
We will have to work out a design since this is a complex tree sturcture. I will assemble so proposals before I implement.
With the cve-checker part of YP, if it can use this data CPE will be really important. But ya, we need to figure out a user interface that will work for this.
This feature is not being used. Will fix it if renewed.
