In particular, this new basic text might have been revised depending on the brand new scope, the latest section to the version brands could have been removed, and you may a unique area has been added to spell it out how to specify relationships anywhere between designs, as well as people regarding the backwards being compatible, in the first place used in § eleven.dos Type guidance.
More over, another type of area is included at the bottom examine new DCAT versioning method having those people used in OWL and you may [ DCTERMS ].
The notion of adaptation is sometimes put since the a generic title to help you denote some sort of matchmaking anywhere between a source and you will a great derived one.
That it point concentrates especially about how to play with DCAT to spell it out types as a consequence of an up-date – we.elizabeth., of alter occurring to help you a source as part of their existence-stage.
For this purpose, DCAT stimulates abreast of present vocabularies, particularly the new versioning component of the latest [ PAV ] ontology, as well as the associated terminology away from [ DCTERMS ], [ OWL2-Review ], and you can [ VOCAB-ADMS ].
It is vital to remember that versioning applies to all top notch citizens DCAT resources, including Magazines, Directory Suggestions, Datasets, Distributions.
Notice along with that the DCAT method demonstrated throughout the following parts is meant to end up being subservient having those people currently found in certain kind of resources (e.g., [ OWL2-Review ] will bring a collection of versioning features to own ontologies), and also in considering domain names and you will groups. Getting an assessment involving the DCAT versioning approach and people away from most other vocabularies, find § 11.4 Subservient answers to versioning.
The thought of adaptation is very much connected with town methods, the details administration coverage while the workflows in position. It is to research business to decide whenever and why another variation are going to be create. Therefore, DCAT refrains out-of getting definitions otherwise legislation on when changes in a resource should come to be a new launch of they, and you can relates to own guidance to [ DWBP ] (§ 8.six Investigation Versioning and you will § 8.seven Analysis Identifiers).
11.step 1 Matchmaking between designs
- Those individuals proving new adaptation chain and you will steps (the new variation background).
- Those individuals demonstrating whether a variety are changed/superseded of the another.
eleven.step one.step one Adaptation chains and you will hierarchies
The previous draft [ VOCAB-DCAT-3-20201217 ] try utilizing comparable attributes away from [ DCTERMS ] and [ VOCAB-ADMS ], namely:
- dcterms:hasVersion / dcterms:isVersionOf , to own variation hierarchies, and you can
- adms:prev , adms:next , adms:last for both items stores and you may dataset show.
is defined as A related resource that’s a variety, release, or type of your discussed investment , ergo using the notion of type in broad sense, while [ PAV ] is especially discussing models because of a posting. is described as A link to the modern otherwise latest variation of your House , while during the [ PAV ] the present day and you may latest types regarding a resource may be various other, and relationship to by using some other functions.
More over, even though the significance of [ VOCAB-ADMS ] services states explicitly that they are supposed to be used for “versions”, he is subproperties of associated words inside the [ XHTML-VOCAB ], where one can use them to connect tips for the a profile (age.g., the latest set of users away from an online site). E.g., the word xhv:last reads as follows: history is the final resort in some tips. .
According to one, within draft, [ PAV ]-similar attributes are used for brands, while the new [ VOCAB-ADMS ] features, and you may qualities dcterms:hasVersion / dcterms:isVersionOf commonly utilized.
Possessions dcat:previousVersion is utilized to construct a variation strings, that is certainly navigated backwards of a given type on the earliest you to. It shows the most widespread explore situation – we.e., hooking up some other models authored since collection of info into the a catalog.
