Introduction

Context

This vocabulary is supporting GeoDCAT-AP, a specialisation of the DCAT application profile for European data portals [[DCAT-AP]] for geospatial data. The terms defined in this namespace are defined as broad as possible for wider reuse but are scoped to the needs of GeoDCAT-AP. All terms in this vocabulary have therefore a strong connection with GeoDCAT-AP.

Revision history

The domain is set to rdfs:Resource while these properties are only meaningful with DCAT ecosystem. Suggestion to change the domain to dcat:Resource. The problem is that dcat:Distribution not a subclass is from dcat:Resource. That would possibly limit the reuse.

Abstract

The GeoDCAT-AP vocabulary supports the GeoDCAT-AP profile. The namespace for this vocabulary is http://data.europa.eu/930/ . It is under maintenance by the SEMIC action, Interoperable Europe.

Conformance Statement

In order to conform to this vocabulary the usage of the terms MUST:

Be in line with the provided definitions
Satisfy the formal constraints such as domain and ranges restrictions, if present

When reusing the terms, the reuse principles of the SEMIC styleguide SHOULD be followed.

To make the properties widely reuseable the domain and ranges are usually very open. For any kind of entity, the class rdfs:Resource is used. For any kind of value, rdfs:Literal is used. In the RDF ecosystem these are the universal denominators.

Terminology

The namespace for this vocabulary is http://data.europa.eu/930/ .

Controlled Vocabularies

For the class Metric the following instances have been defined.

Instance	URI	Class	Usage note
+Spatial resolution as angular distance	`geodcat:spatialResolutionAsAngularDistance`	`dqv:Metric`	Spatial resolution expressed as angular distance [[ISO-19115-1]], by using a decimal degree.
+Spatial resolution as distance	`geodcat:spatialResolutionAsDistance`	`dqv:Metric`	Spatial resolution expressed as distance. It corresponds to the notion of spatial resolution as "ground distance" of [[ISO-19115]] and "horizontal ground distance" of [[ISO-19115-1]].
+Spatial resolution as equivalent scale	`geodcat:spatialResolutionAsScale`	`dqv:Metric`	Spatial resolution expressed as equivalent scale [[ISO-19115]], [[ISO-19115-1]], by using a representative fraction (e.g., 1:1,000, 1:1,000,000).
+Spatial resolution as vertical distance	`geodcat:spatialResolutionAsVerticalDistance`	`dqv:Metric`	Spatial resolution expressed as vertical distance [[ISO-19115-1]]. In GeoDCAT-AP, this property is typically used for Catalogues, Data Services, and Datasets. However, no domain restriction is defined, and therefore this property can be used on any resource.
