Using dcat:next and dcat:version in Dataseries

Problem statement

Should dcat:prev and dcat:next be updated when a dataset in the serie is revised ?

Let’s consider example 38


ex:budget a dcat:DatasetSeries ;
  dcterms:title "Budget data"@en ;
  .

ex:budget-2018 a dcat:Dataset ;
  dcterms:title "Budget data for year 2018"@en ;
  dcat:inSeries ex:budget ;
  dcterms:issued "2019-01-01"^^xsd:date ;
  dcat:next ex:budget-2019 ;
  .

ex:budget-2019 a dcat:Dataset ;
  dcterms:title "Budget data for year 2019"@en ;
  dcat:inSeries ex:budget ;
  dcterms:issued "2020-01-01"^^xsd:date ;
  dcat:prev ex:budget-2018 ;
  dcat:next ex:budget-2020 ;
  .

ex:budget-2020 a dcat:Dataset ;
  dcterms:title "Budget data for year 2020"@en ;
  dcat:inSeries ex:budget ;
  dcterms:issued "2021-01-01"^^xsd:date ;
  dcat:prev ex:budget-2019 ;
  .

Now let’s consider that budget-2019 is revised with a new dataset budget-2019-rev1

Dataserie can be updated in different ways

budget-2019-rev1 can replace budget-2019 in the serie
- As a consequence budget-2018 and budget-2020 have to be updated for dcat:next / dcat:prev fields
budget-2019-rev1 can be inserted in the Dataserie in between budget-2019 and budget-2020
- As a consequence, budget-2019 and budget-2020 have to be updated for dcat:next / dcat:prev fields
No update to the dataserie.
- When encountering a dataset is a serie, one must check if a new version is available for this dataset.
budget-2019 is turned into a Dataserie and holds budget-2019-rev0 and budget-2019-rev1
- This seems to be over engineering here

What will be the recommendation?

@sde01 , apologies for the late reply.

The case you outline can be addressed by combining dataset series with dataset versions:

flowchart BT
C1(ex:budget-2019-rev1)
C0(ex:budget-2019-rev0)
B2(ex:budget-2020)
B1(ex:budget-2019)
B0(ex:budget-2018)
A(ex:budget)
C0 & C1--dcat:isVersionOf-->B1
B0 & B1 & B2--dcat:inSeries-->A

The link between versions is specified via property dcat:previousVersion:

flowchart RL
C1(ex:budget-2019-rev1)--dcat:previousVersion-->C0(ex:budget-2019-rev0)

So, Example 38 could be revised as follows:

ex:budget a dcat:DatasetSeries ;
  dcterms:title "Budget data"@en ;
  .

ex:budget-2018 a dcat:Dataset ;
  dcterms:title "Budget data for year 2018"@en ;
  dcat:inSeries ex:budget ;
  dcterms:issued "2019-01-01"^^xsd:date ;
  dcat:next ex:budget-2019 ;
  .

ex:budget-2019 a dcat:Dataset ;
  dcterms:title "Budget data for year 2019"@en ;
  dcat:inSeries ex:budget ;
  dcat:hasVersion ex:budget-2019-rev0 , ex:budget-2019-rev1 ;
  dcat:hasCurrentVersion ex:budget-2019-rev1 ;
  dcterms:issued "2020-01-01"^^xsd:date ;
  dcat:prev ex:budget-2018 ;
  dcat:next ex:budget-2020 ;
  .

ex:budget-2019-rev0 a dcat:Dataset ;
  dcterms:title "Budget data for year 2019"@en ;
  dcat:version "rev0" ;
  dcat:isVersionOf ex:budget-2019 ;
  dcterms:issued "2020-01-01"^^xsd:date ;
  .

ex:budget-2019-rev1 a dcat:Dataset ;
  dcterms:title "Budget data for year 2019"@en ;
  dcat:version "rev1" ;
  dcat:isVersionOf ex:budget-2019 ;
  dcat:previousVersion ex:budget-2019-rev0 ;
  dcterms:issued "2020-05-10"^^xsd:date ;
  .

ex:budget-2020 a dcat:Dataset ;
  dcterms:title "Budget data for year 2020"@en ;
  dcat:inSeries ex:budget ;
  dcterms:issued "2021-01-01"^^xsd:date ;
  dcat:prev ex:budget-2019 ;
  .

I propose to close this issue if there are no further requests by @sde01.

Hello Riccardo Thanks for your feedback. Your proposal is crystal clear.

Many thanks

I think it would be great to revise the example as @andrea-perego suggested to include this use case in the spec.

andrea-perego commented 2 years ago

@sde01 , we have decided to add a consolidated version of your example in the specification. It is now included in the Editor's Draft (PR https://github.com/w3c/dxwg/pull/1473):

Thanks for your contribution.
