KDM — Section: 11

Inventory model as part of the Source package instead of Build There is one flaw in the current architecture of KDM: SourceRegion elements are part of the L0 compliance point, however the SourceFiles are defined in Build package, which is in L1. It would be much better to consolidate SourceFile elements and alike into a special “Inventory model” (the list of elements representing all artifacts as first class KDM citizens), right in the L0, for example as part of the Source package. In fact, all implementers so far are doing just that: they are aiming at supporting L0 with “limited support for Build”. Everybody seems to have an inventory model, and it makes perfect sense to have it right in the L0. The Build package makes sense on its own right as the place where we represent the “Engineering view” of the software system, i.e. the transformations between the artifacts (for example, files A.c, B.c, and C.c as well as the library GGG.lib are compiled into the executable XYZ.exe, where file A.c is provided by supplier S1, and the GGG.lib is provided by supplier S1, and the transformation requires tool T1 and is described in file “makefile”).
