IBM Quality Manager provides an API for accessing the history of individual resources as well as the history of archived/deleted resources. You can read about the supported resources types and more on https://jazz.net/wiki/bin/view/Main/RqmApi#historyUrl
I have recently discovered an RSS feed for all the support documents concerning Rational Publishing Engine: RPE Support RSS. Technotes, interim fixes, APARs are present there.
You can get more feeds from the IBM Support Feeds page. Here are some examples for producys typically used with RPE:
- Rational DOORS Next Generation Support RSS
- Rational Quality Manager Support RSS
- Rational Team Concert
- Rational DOORS 9 Support RSS
- Rational Rhapsody
