adms:last is defined as A link to the current or latest version of the Asset, whereas in [[PAV]] the current and latest versions of a resource may be different, and link to by using different properties.
Moreover, although the definitions of the [[VOCAB-ADMS]] properties states explicitly that they are meant to be used for "versions", they are subproperties of the corresponding terms in [[XHTML-VOCAB]], where they are used to link resources in a collection (e.g., the set of pages of a Web site). E.g., the definition of xhv:last reads as follows: last refers to the last resource in a collection of resources.

Based on that, in this draft, [[PAV]]-equivalent properties are used for versions, whereas the [[VOCAB-ADMS]] ones are used for dataset series (). Properties dcterms:hasVersion / dcterms:isVersionOf are not used.

Property dcat:previousVersion is used to build a version chain, that can be navigated backward from a given version to the first one. This reflects the most typical use case - i.e., linking different versions published as distinct resources in a catalog.
With "dataset series" we refer to data, somehow interrelated, that are published separately. An example is budget data split by year and/or country, instead of being made available in a single dataset.

In such cases, it might be important to link the yearly releases with relationships specifying the previous, next, and latest ones. In such scenario, DCAT makes use of the [[VOCAB-ADMS]] properties adms:prev, adms:next, and adms:last, respectively.

Properties about dataset series can be classified into two groups.
-The first group is about properties describing the dataset series itself. For instance, this is the case of property dcterms:accrualPeriodicity, whose value should correspond to the frequency upon which a new child dataset is added.

The second group is about properties reflecting the dimensions described in child dataset metadata, via upstream inheritance - i.e., property values of child datasets are inherited by their parent (the dataset series).

In particular, properties concerning the creation / publication / update dates of child datasets may affect the corresponding ones in the series. For these properties, DCAT recommends the following approach:
