Example of Competency Questions used for designing core metadata schema
As part of creation of core metadata schema (based on DCAT-AP), Health-ri drafted have crafted a set of competency questions which showcase how the minimum core metadata schema can be useful for fulfilling the needs for finding and searching a different types of research resource. We first present a table of our competency question list with the setting they correspond to and answers, and, we then present SPARQL query implementations for these questions.
The requirements covers the minimum needs to fulfill the requirements for finding (discoverability) research resources in particular datasets on health-ri portal.
The core metadata schema provides generic, top level elements and is independent of the health and scientific domain.

Core metadata requirements
The initial goal and functionality that the metadata model must support is to enable the users in finding (Findability) and access/requesting (Access, Request) the research resource on the national catalogue.
We collected the metadata requirements in the form of competency queries.
Req category | Example of Competency Question | Candidate Answers |
|---|---|---|
F | What keywords, or topics are there to discover the datasets? | Collect vocabularies and their relations for defining the health research domains (health, clinical, omics, imaging) |
F | What types of research resources can i search for? | Dataset, Distributions, Registries, Bio Samples, Questionnaires, Codes, Protocols, Image collections, |
F | Can user search for datasets based on temporal information? | date published? date range? |
F | What are the comprehensive set of metadata elements to describe research datasets? | dataset characteristics, title, description, theme |
F | Which institution, Research group is the provider of this dataset? | |
F, Reuse | What processes has been done on the dataset? what services can be shared with the dataset? | dataset service, provenance and lineage of the data |
F, Reuse | What are the versions of a dataset? | |
Access | What are the types of accessibility of a dataset, including licensing and access restrictions? | types of license, |
A, Reuse | Can user specify the data format and data distribution methods for requesting the dataset? | distributions |
Reuse | what are the information on how to access and download datasets | |
Joining dataset | Can users discover relationships between different datasets? | |
Reuse | Can I track changes or modifications made to a dataset over time? | |
access/reuse | Can I find information on data usage policies and terms related to a dataset? | |
F, interoperabiltity | Can I find the related resources, such as publications. study, project, services to the dataset? | |
Interoperability | can dataset metadata be integrated with other data catalogs or systems? | |
F/interoperabiltiy | what is the URIs for metadata records (instances) (global unique, persistent and resolvable) | URIs naming conventions for the metadatasets |
F/interoperability | What is URIs for the metadata schemas ? | URIs naming convenstions for the model |
F-Interoperabolity | What schema language is used for formal representing of generic concepts | RDFS, OWL, SKOS, |
F-Interoperabolity | What schema language is used for defining data validating rules, constraints, profilings and … | Shacl |
Given these generic requirements, we collected the core terms, definitions to be used for semantic modelling.
