Profile of metadata standards for EUDM datasets
This ontology contains a range of resources describing a profile of well-known metadata standards to be used to characterise datasets within the EUDM project.
- alignments/
- listed and documented alignments of this profile (of DCAT) several other metadata models including schema.org, AGRIF and AGLS.
- model/
- the metadata model for this profile, including schemas & constraints
- note the parts of the model are formalised according to PROF (see next section)
- vocabs/
- vocabularies used by this profile. Note that many of the vocabularies references in this profile are managed elsewhere.
The metadata model for EUDM is essentially the DCAT 2018 metadata model currently under development by the W3C's Dataset Exchange Working Group with a series of restrictions placed on it that require certain EUDM-specific properties to be used.
Figure 1 shows the basic DCAT classes adapted from the DCAT vocabulary diagram.
Figure 1: This EUDM profile described using the Profile Description Ontology.
Figure 2 shows some of the EUDM-specific restrictions formalised in the dataset constrains file.
Figure 2: Some of the EUDM constraints on DCAT Datasets and related classes.
Figure 3 shows Figure 2 with some explanatory notes in plain English (in red) detailing the requirements EUDM imposes on general DCAT classes and properties.

This profile is described using the emerging Profile Description Ontology (PROF), currently under development by the W3C's Data Exchange Working Group of which the authors are members.
PROF is managed here:
Within the documentation of PROF is contained this profile's description as an example:
The image of describing this profile is also reproduced below.

The constraints for this profile are expressed using Shapes Constraint Language (SHACL).
