I urge the DCAT editors to defer fine-grained versioning & change details to Dataset modelling and to not to try to cater for them at the DCAT the metadata level. 

Consider: a large dataset like the Australian Address Database has addresses added and removed every few months, so should it have a long list of Distributions? No! The Dataset is the overall thing and Address addition/removal/change is annotated at the Feature (sub-Dataset) level since it is complex and knowledge about what an 'Address' is - a sub-Dataset element - is needed to correctly use such information.

My motivation for stepping in here is that I would hate to see DCAT get too expressive: more skill in the vocabulary will harm adoption for simple catalogues given the perception of it being "heavyweight" and broad adoption is more important to me that deep skill. 

Anyway, there are already many Semantic Web ways to model versioning issues (e.g. [PAV](https://pav-ontology.github.io/pav/)) that are DCAT-compatible. So use DCAT for the catalogue and drop down into fine-grained versioning in PAV, SDMX/QB etc. as needed.
