LINDAS Specifics
Current usage of predicates on the observations used to propose sorting on in visualize.admin.ch:
- schema:name -> Name / Nom / Name
- schema:identifier -> Identifikation / identifient / Identifier
- schema:alternateName -> Abkürzung / abréviation / Abbreviation
To specify the order of values in a dimension one can use schema:order. For example to specify which value in an ordinal scale is lower than another. Example in Cube-Creator (EIAM access required) and on LINDAS
The categories defined by opendata.swiss are reflected and used through https://register.ld.admin.ch/opendataswiss/category
BAFU Specific Categories are based on https://register.ld.admin.ch/foen/theme
Dimensions with a meta:dataKind attached schema:GeoShape need a geo:hasGeometry per entry attached (e.g. https://ld.admin.ch/dimension/bgdi/biota/productionregions/4), pointing to the corresponding entry (e.g. https://geo.ld.admin.ch/biota/productionregion/geometry/4) on the Swisstopo Endpoint reachable per SPARQL on https://geo.ld.admin.ch/query.
Based on https://github.com/zazuko/rdf-cube-schema-viz/blob/master/README.md#version-history-of-cubes it is necessary to attache to the cube

Per opendata.swiss Organisation a new harvester needs to added to opendata.swiss CKAN.
Upon publication of a new version of a cube the legacy versions feature an additional property to inform the above Tools of its expiration.
<cube> schema:expires ?dateTimeOfUpdate
To filter for the latest published version of a cube a SPARQL query typically includes
<parent> schema:hasPart ?cube .
?cube a cube:Cube .
?cube schema:creativeWorkStatus <https://ld.admin.ch/vocabulary/CreativeWorkStatus/Published> .
FILTER( NOT EXISTS { ?cube schema:expires ?ex . } )
An organization may request its publishing profile for cube creator by opening an issue and providing the following information:
-
A short identifier. The identifier should be the English abbreviation of the organization. It will be used in namespaces hence the guidelines allow only lowercase letters.
-
A label in multiple languages. The required languages are English, German, French and Italian.
-
The subject. One of the theme-based subdomains of
ld.admin.ch. -
The organization IRI. It will be used as the default value in cubes for the property
cube:observedBy. It may be an office or some other organization above or below in the hierarchy.
As an example, the following is the data for the Federal Administration Training Centre:
- identifier: fatc
- label en: Federal Administration Training Centre
- label de: Ausbildungszentrum der Bundesverwaltung
- label fr: Centre de formation de l'administration fédérale
- label it: Centro di formazione dell'Amministrazione federale
- subject: education.ld.admin.ch
- IRI: https://ld.admin.ch/office/V.1.4
A separate registration process is needed to publish cubes also on opendata.swiss.
Opendata.swiss displays resources with the prefix "visualize.admin.ch" as an iframe. This means that when a dcat:Distribution has the prefix "visualize.admin.ch" in its dct:title, the accessURL is displayed as an iFrame. See:

To my knowledge, this resource is automatically added when I activate the publication on opendata.swiss in LINDAS. Alternatively, I can manually create a publication in the CKAN backend and add a corresponding resource. The relevant fields are "Title" and "Access URL".
