In some aspects I still think, C1 was never aimed or planned as a DAM, it just so happened they patched some functions in.

True. It was not meant to be a DAM for most of its life, just a high quality raw converter. But with the rise of LR and Aperture, they had to react. Their first attempt was to buy Media Pro from MS and make it a companion product alongside C1 to capture the DAM part. But that approach never really worked. So that's when they started to add library functionality into C1 (with version 7, IIRC).
 

And the library functions are stepchild of Phase One, there's no other way to see that. I still have to repair one library. It was my fault it went south with it, but the repair actions are troublesome.

What happened?
