showrooms

Welcome to the showrooms of the Norwegian Digitalisation Agency (Digdir) ⧉, with RDF-based machine-readable demo resources!

Feedback: Please provide your feedback as Github Issues ⧉, if any.

Disclaimer: The demo resources made available from the various showrooms are meant for demo purposes only.

Purpose

The main purpose of the showrooms is to

demonstrate how to use the various RDF-based Norwegian national specifications to make available machine-readable resources in accordance with the specifications;
demonstrate how to cross-reference/link between the resources across the specifications;
provide reusable and machine-readable RDF-based resources, for testing and demonstration purposes.

Audience

The showrooms are primarily meant for you who have certain knowledge of RDF, and when you are e.g.

implementing one or more of the RDF-based Norwegian national specifications demonstrated in the showrooms,
looking for some RDF-examples of the usage of the specifications,
looking for some "building blocks" (instances in RDF) to test your implementation of the specifications,
or simply wondering how resource descriptions in accordance with the specifications may look like in RDF.

The showrooms are also meant for you who are our international colleague and who want to learn more about our national RDF-based specifications for data sharing and reuse.

Overview and cross-references between the showrooms

We have currently following showrooms with cross-references between the showrooms:

Classifications / controlled vocabularies: In this showroom we will demonstrate the usage of XKOS-AP-NO ⧉ (the Norwegian application profile of DDI’s XKOS ⧉), to describe and publish machine-readable classifications, controlled vocabularies, code lists etc.
Concepts: In this showroom we will demonstrate the usage of SKOS-AP-NO-Begrep ⧉ (the Norwegian application profile of W3C’s SKOS ⧉), to describe and publish machine-readable concepts and concept collections.
Datasets, data services etc.: In this showroom we will demonstrate the usage of DCAT-AP-NO ⧉ (the Norwegian application profile of EU’s BRegDCAT-AP ⧉), to describe and publish machine-readable descriptions of datasets with distributions and data services.
Data quality: In this showroom we will demonstrate the usage of DQV-AP-NO ⧉ (the Norwegian application profile of W3C’s Data Quality Vocabulary ⧉), to describe data quality.
Information models: In this showroom we will demonstrate the usage of ModellDCAT-AP-NO ⧉ (the Norwegian application profile of DCAT-AP-NO ⧉), to describe and publish machine-readable descriptions of information models.
Services and events: In this showroom we will demonstrate the usage of CPSV-AP-NO ⧉ (the Norwegian application profile of EU’s CPSV-AP ⧉), to describe services and events and publish machine-readable descriptions.
URIs and dereferenced URIs: The "master key" to the showrooms is URI. In this showroom we will demonstrate one way to implement the Norwegian URI-standard ⧉ (based on EU’s 10 Rules for Persistent URIs ⧉).
Generic dummy assets: Not directly related to one particular specification per se, but this showroom contains a number of reusable, machine-readable and generic dummy assets which may be used as "building blocks" when you e.g. test your implementation of a given specification.

Figure 1 illustrates some of the cross-references between the resource types that are demonstrated in the various showrooms. The cross-references will be explained in the respective showrooms.

Making the resources findable via a data portal

The Norwegian national specifications demonstrated in the various showrooms here, are also specifications for how to make the resource descriptions (metadata) available in a data portal, and in particular, the National Data Catalog of Norway ⧉ maintained by the Norwegian Digitalisation Agency.

In order to make the resource descriptions available in the National Data Catalog, you may, if you are authorized to do so on behalf of your organization,

use the registration services, to register your datasets, concepts etc., which will then be automatically harvested to the National Data Portal, or
use the harvesting services, to specify the URLs where your machine-readable resource descriptions are made available for harvesting to the National Data Catalog.

This is illustrated in Figure 2, which also shows the usage of the national specifications in the data portal.

There is also a demo portal ⧉ provided by the Norwegian Digitalisation Agency, which has the same functionalities as in the National Data Catalog, but the content in the demo portal is only meant for testing and demonstration purposes. Note that you need to be a registered user in the demo portal in order to use the editor and/or harvester of the demo portal.

Using the harvesting services, all the demo resources that are demonstrated in the various showrooms here are, or will be, automatically harvested to and thus also findable via the demo portal.

Examples for how to find some of the demo resources in the demo portal:

demo classifications / datasets: by for instance searching "demodataset" in the "Datasets" part of the demo portal ⧉.
demo concepts (not yet): by for instance searching "demoCpt" in the "Concepts" part of the demo portal ⧉.
demo information models: by for instance searching "demomodel" in the "Information models" part of the demo portal ⧉.
