jakubklimek has just created a new issue for https://github.com/w3c/dxwg:

== dcat:Catalog/dct:hasPart inconsistent with DCAT-AP v1.1 ==
In [DCAT-AP v1.1](https://joinup.ec.europa.eu/release/dcat-ap-v11) the `dct:hasPart` property on `dcat:Catalog` has a specified range `dcat:Catalog` and is used to create a hierarchy of catalogs, specifically, it is described as `This property refers to a related Catalogue that is part of the described Catalogue`. This is also mentioned in https://github.com/w3c/dxwg/issues/116#issue-297283045. 

In [DCAT revision](https://w3c.github.io/dxwg/dcat/#Property:catalog_hasPart), it currently has a range `dcat:Resource`. It is used as a superproperty of `dcat:dataset` for inclusion of datasets in catalogs, and `dcat:service` for inclusion of services.

However, `dcat:Catalog` is not a subclass of `dcat:Resource`, hence the inconsistency.

1. Do we actually need a superproperty of `dcat:dataset` and `dcat:service`? Is it abstract (not to be used) or are there now entities other than datasets and services allowed in Catalogs? (related to #317)
2. If so, does it need to be `dct:hasPart` ? It could be some other property, leaving `dct:hasPart` as a relation between two catalogs.
