Initial simple separation to get the process of extracting dvc-objects and dvc-data packages out of dvc. dvc-objects is for: * defining base Object (aka HashFile) and ObjectDB * providing tools to work with those objects (check/transfer/etc) * etc dvc-data is for: * defining higher level objects (e.g. Tree) * bulding objects from the workspace (aka staging) * projecting objects back into the workspace (aka checkout) * comparing Tree objects (aka diff) * defining misc object databases (e.g LocalObjectDB) * higher-level transfer (e.g. with Tree indexes) * etc For example, the objects we use in run-cache are based on dvc-objects and not on dvc-data, as they have absolutely nothing to do with data management. There are still some mixups in the code that will be addressed in the followups.
