FOSS distributions are composed of dozens of thousands packages, and hundreds of thousands of dependencies. Visualizing such huge graphs in a way that allows to identify some interesting features is a real challenge.
In Mancoosi, we propose to extract from the huge graph a much smaller one, built out of packages which are in a relationship called strong dominance (reminiscent of the notion of dominance used by compilers when analyzing control flow graphs): in practice, the resulting graph of strong dominators is much smaller and allows to visualize the architecture of the components of a distribution.
The technical definitions, as well as a detailed discussion of these notions, can be found in a technical report titled .
This page provides pointers to the daily analysis of mainstream FOSS distributions provided by Mancoosi as a service to the FOSS community.
