Abstract


The National Health Data Catalogue uses a core metadata schema: a set of minimal elements for describing each resource (e.g. dataset) with common metadata. It defines the requirements to access and reuse information across Health-RI nodes via the National Catalogue. This document contains the specification details on the Health-RI core metadata schema.

1. Permanent Urls

1.1. Metadata Resources

To support long-term FAIR (Findable, Accessible, Interoperable, and Reusable) access to Health-RI Metadata Schema resources, we provide persistent URLs using the W3ID system. These permanent identifiers improve the findability and accessibility of the related artifacts. The following W3ID redirects are available for Health-RI metadata:

3. Audience Documentation

3.1. Purpose and audience

This branch contains the 2nd version of the Health-RI core and generic health metadata schema for the National Health Data Catalogue, detailing the classes and entities involved and offering usage notes for developers. It addresses the schema’s design and application but excludes discussion on the National Health Data Catalogue and its onboarding process (these are described here). Please also visit Confluence for general information about the metadata schema and metadata mapping. Please note that we are currently still working on the implementation of the new schema into the frontend of the National Health Data Catalogue.

This documentation aims at a technical audience tasked with implementing the metadata schema and stakeholders interested in a detailed understanding of the core metadata schema. With any further questions or comments please contact Health-RI via the Health-RI ServiceDesk or via servicedesk@health-ri.nl.

4. Introduction

4.1. Scope and Current State of the Schema

Building on the 1st version of the metadata schema, version 2 aims to incorporate both DCAT-AP NL and the (yet-to-be-finalized) HealthDCAT-AP, along with Health-RI-specific requirements for the National Health Data Catalogue. It introduces several health-related properties (marked in blue in the UML diagram below), with suggested or required controlled vocabularies where applicable.

Important Note: HealthDCAT-AP has not yet been officially finalized and remains subject to change. Once its official release is published, Health-RI will reevaluate compatibility with HealthDCAT-AP. This version is based on the draft dated 16-12-2024. In that draft, the cardinalities of HealthDCAT-AP vary depending on different access rights (public, restricted, non-public). For now, compliance is ensured with the open version, using its UML diagram for reference.

Additionally, several ELSI-related metadata fields, as gathered by the Health-RI ELSI team, have been included in this version 2. These fields are not mandatory but will be evaluated upon implementation in the catalogue.

To indicate the nature of the data (e.g., whole genome sequencing or questionnaire data), we propose using healthdcatap:healthTheme. For synthetic data, use dct:type with the required controlled vocabulary in the dcat:Dataset class.

Several classes from DCAT-AP NL and draft HealthDCAT-AP have been included but not further specified for Health-RI yet. This includes the DataService class, meaning that these classes can be used but are not yet tailored to specific dataholder needs for the National Health Data Catalogue.

4.3. Overview and Diagram

An overview of the metadata schema core is presented in the UML diagram below. This UML diagram showcases primary classes (entities), excluding detailed definitions such as rdfs:label and rdfs:comment. Each block represents a class and lists its attributes (properties). Where properties reference another class, their range is displayed in pink font.

If a class is linked to another class with a closed arrow, it inherits all properties from the other class (e.g., dcat:Dataset inherits from dcat:Resource). Other arrows represent relationships, including their types (e.g., dcat:Dataset connects to a dcat:DatasetSeries via dcat:inSeries), along with cardinalities (e.g., dcat:Dataset connects to zero or more dcat:DatasetSeries). Mandatory relationships are marked with dark labels, while recommended relationships use a lighter color.

The UML diagram separates main classes from supporting classes. While relationships between main classes are indicated by arrows, supporting class relationships are not visually connected via arrows to maintain clarity in the diagram. Instead, they can be deduced from the pink-colored property ranges listed per class.

Properties derived from draft HealthDCAT-AP (mostly within the dcat:Dataset class) are marked blue.

A tabular overview of all classes and properties—including their range, cardinality, controlled vocabulary (if applicable), and usage notes—is provided below. A reference sheet containing this information can be found here. This sheet also documents property histories (compared to v1 of the Health-RI core metadata schema) and specifies the origins of new constraints (whether they stem from DCAT-AP v3, DCAT-AP NL, or HealthDCAT-AP).

4.5. Usage Notes on Schema / Mapping

5. Classes

5.1. Mandatory Terms

Class name HealthDCAT-AP Definition Usage Note URI
Catalog A catalogue or repository that hosts the Datasets or Data Services being described. A catalog that is listed in the National Health Data catalog and contains one or several datasets and/or data services. Used to describe a bundle of datasets (and other resources) under a single title, for example, a collection. dcat:Catalog
Dataset A conceptual entity that represents the information published. When focusing on health data, a dataset typically contains structured information gathered from a study or research project related to health topics. This might include clinical trial results, public health statistics, patient records, survey data, etc.
How the data in a dataset can be accessed is defined in the Distribution, which usually points to the actual data files available for access or download. Datasets are often included in a catalog, which organizes and provides metadata about multiple datasets, making them easier to find and use. The term 'agent' refers to any entity responsible for creating, maintaining, or distributing the dataset. 		dcat:Dataset
Agent Any entity carrying out actions with respect to the (Core) entities Catalogue, Datasets, Data Services and Distributions. A person or organisation that is associated with the catalogue or dataset. This class is instantiated in these classes whenever the range is foaf:Agent. foaf:Agent
Kind A description following the vCard specification. Used to describe contact information for Dataset and DatasetSeries. This class is instantiated in these classes whenever the range is vcard:Kind. vcard:Kind
Class name HealthDCAT-AP Definition Usage Note URI
Data Service A collection of operations that provides access to one or more datasets or data processing functions. A Data service offers the possibility to access and query the data of one (or several datasets) through operations. It offers more extensive possibilities to access the data than the Distribution through a variety of potential actions. dcat:DataService
Dataset Series A collection of datasets that are published separately, but share some characteristics that group them. A Dataset Series is a collection of similar datasets that are somehow interrelated but published separately. An example is consecutive datasets split by year and/or datasets separated by location. Instead of being made available in a single dataset, the individual (e.g. yearly) datasets are linked together with the Dataset Series class. dcat:DatasetSeries
Distribution A physical embodiment of the Dataset in a particular format. Used to describe the different ways that a single dataset can be made available. I.e., it can be downloaded or it can be accessed online in one or more distributions (e.g. one in a downloadable .csv file, another file with an access or query webpage). dcat:Distribution
Attribution Attribution is the ascribing of an entity to an agent. This class is instantiated by the property "qualified attribution" (prov:qualifiedAttribution) in other classes. Use this class to describe any Agent (other than publisher or creator) that has some form of responsibility for the resource. Within the class, this Agent is described with an instance of foaf:Agent, and the role is chosen from a controlled vocabulary. This class can be used to indicate the funding agent that provided funding for the dataset. prov:Attribution
Checksum A value that allows the contents of a file to be authenticated. This class is instantiated by properties in other classes that have the range spdx:Checksum. spdx:Checksum
Identifier An identifier in a particular context, consisting of the string that is the identifier; an optional identifier for the identifier scheme; an optional identifier for the version of the identifier scheme; an optional identifier for the agency that manages the identifier scheme. This class is instantiated by the property "other identifier" (adms:identifier) in other classes. Use this class to provide any additional identifier to the resource or dataset that is not the primary identifier provided in dct:identifier. adms:Identifier
Period of Time An interval of time that is named or defined by its start and end dates. This class is instantiated by properties in other classes that have the range dct:PeriodOfTime. dct:PeriodOfTime
Relationship An association class for attaching additional information to a relationship between DCAT Resources. This class is instantiated by the property "qualified relation" (dcat:qualifiedRelation) in other classes. Use this class to describe a relationship with another resource or dataset. Within the class, that resource is indicated, as well as the role this resource has in relation to the described one. The role is indicated based on a controlled vocabulary. dcat:Relationship
Quality Certificate An annotation that associates a resource (especially, a dataset or a distribution) to another resource (for example, a document) that certifies the resource’s quality according to a set of quality assessment rules. This class is instantiated by the property "quality annotation" (dqv:hasQualityAnnotation) in other classes. Use this class to provide a link between the resource or dataset and an associated quality annotation. dqv:QualityCertificate

7. Further Information

7.1. Model extension

This is a Health-RI core metadata schema, which means it is designed to be “minimal” and cover the basic metadata elements of catalogue resources. If you come from a specific working group or domain and see some of the important elements from your domain should be represented in the metadata, you could build an extension (or so-called petal) of this model for your domain’s specific needs. For more information on this, please check out the process description for domain-specific metadata.

Conformance

Conformance requirements are expressed with a combination of descriptive assertions and RFC 2119 terminology. The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in the normative parts of this document are to be interpreted as described in RFC 2119. However, for readability, these words do not appear in all uppercase letters in this specification.

All of the text of this specification is normative except sections explicitly marked as non-normative, examples, and notes. [RFC2119]

Examples in this specification are introduced with the words “for example” or are set apart from the normative text with class="example", like this:

This is an example of an informative example.

Informative notes begin with the word “Note” and are set apart from the normative text with class="note", like this:

Note, this is an informative note.
