Particularly, the newest introductory text might have been revised according to new extent, the new point into version designs has been got rid of, and a separate part is included to describe how exactly to establish dating anywhere between sizes, as well as people regarding backwards being compatible, to begin with found in § eleven.dos Variation advice.
Moreover, a different area has been added in the bottom to compare the fresh DCAT versioning means with those utilized in OWL and you can [ DCTERMS ].
The idea of type is usually made use of while the a general title to help you signify some sort of matchmaking anywhere between a source and a good derived one to.
It section centers particularly about how to explore DCAT to explain sizes through an enhance – i.elizabeth., away from alter taking place to help you a resource within their lifestyle-cycle.
For this reason, DCAT produces up on existing vocabularies, in particular the brand new versioning part of the newest [ PAV ] ontology, and the related terminology from [ DCTERMS ], [ OWL2-Analysis ], and you may [ VOCAB-ADMS ].
It is very important observe that versioning can be applied in order to some of the first class people DCAT information, plus Catalogs, Directory Information, Datasets, Distributions.
Note along with that DCAT strategy discussed from the adopting the areas is meant to getting complementary that have the individuals already found in specific types of resources (e.g., [ OWL2-Overview ] will bring a set of versioning properties having ontologies), plus in provided domains and you will teams. For an assessment between the DCAT versioning method and those out-of other vocabularies, come across § eleven.4 Complementary answers to versioning.
The very thought of type is very much indeed linked to the community methods, the information and knowledge administration policy and also the workflows in place. It is up to research business to determine whenever and just why yet another type should be put out. Thus, DCAT refrains of bringing meanings otherwise rules on when changes in a source is always to become a different sort of release of they, and you can relates for guidance so you can [ DWBP ] (§ 8.six Research Versioning and you may § 8.7 Study Identifiers).
eleven.step one Matchmaking anywhere between items
- Men and women appearing the fresh adaptation strings and steps (brand new version background).
- The individuals indicating if a variety is actually changed/superseded from the another one.
eleven.1.step one Variation stores and you may hierarchies
The last draft [ VOCAB-DCAT-3-20201217 ] was making use of similar qualities out-of [ DCTERMS ] and you may [ VOCAB-ADMS ], namely:
- dcterms:hasVersion / dcterms:isVersionOf , to have variation hierarchies, and you will
- adms:prev , adms:second , adms:last for each other systems stores and dataset show.
is defined as A related money which is a version, model, or variation of your own revealed financial support , thus using the concept of variation in greater sense, while [ PAV ] try specifically outlining versions because of a revision. is defined as A relationship to the modern otherwise most recent version of the House , while for the [ PAV ] the current and you can newest systems from a resource tends to be other, and you will link to that with various other functions.
Furthermore, whilst significance of your [ VOCAB-ADMS ] qualities says clearly they are intended to be used in “versions”, he’s subproperties of the involved terms and conditions when you look at the [ XHTML-VOCAB ], where they are utilised to help you hook up information into the a collection (elizabeth.g., brand new gang of pages away from an online site). E.g., the word xhv:last reads below: past is the last resort in a couple of info. .
Predicated on you to definitely, inside draft, [ PAV ]-similar attributes can be used for models, while new [ VOCAB-ADMS ] functions, and you may features dcterms:hasVersion / dcterms:isVersionOf aren’t utilized.
Assets dcat:previousVersion is utilized to build a variety strings, which is often navigated backward of a given type on very first you to. Which reflects the most frequent use case – i.age., linking different sizes published because the type of information during the a list.
