Stumbled on this awesome site today:
It is basically a site built for everyone using IBM Cognos TM1 and saying, "I can't be the only one who needs to do this". Open source TM1 Turbor Integrator processes are available for download. They only ask that you contribute your improvements or help with the guides/manuals for the TI processes.
From their front page:
If you download and install Bedrock TI you will notice vast improvements in your time-to-market, cost of ownership and a marked reduction in TI code and hence system risk. Your TM1 documentation will also be kick-started with comprehensive help documents. White papers describe Best Practice approaches to TM1 and core explanations of TM1 functionality for beginners exist in a series of Training Papers.
Hopefully I can stop feeling like I'm reinventing the wheel with TM1.
