cenrep is Central Repository, somewhat similar to Registry in Windows, just it has two levels (repository id and keys of various types inside the repositories), no tree structure. centralrepository.h is the header, CRepository is the class.
For system applications you can find many keys documented in the ex-open source code (symbiandump project on SourceForge), and some of them are also documented in the Wiki of this site.
