A catalogue consists of

• a front-end application in which a user can search for data

• a catalogue that manages descriptions of datasets available to the portal

• one or more FAIR data points that are the source of metadata for the catalogue

A FAIR data point can be configured locally as a stand-alone application or integrated into a platform (e.g. Molgenis). See also: Metadata onboarding on the National Health Data Catalogue

National health data catalogue (NHC) components

The NHC consists of two parts

• the frontend where the user searches within the catalog metadata

• the backend that:

  • responds to search and consultation actions that the user does on the front end

  • ensures that the catalogue remains up to date by updating the metadata from the FAIR data points

Details

The catalogue frontend is built on Vue.js.

The catalogue backend consists of

• CKAN, an open-source data management system hosted by ISO 27001 certified partner Civity, GNU AGPLv3 license used by EU, NHS. (eng Open-source data management system hosted by ISO 27001 certified partner Civity, GNU AGPLv3 licensed used by EU, NHS) for the storage of the (meta)data

  • The default CKAN metadata harvester has been modified to support FAIR data points

• SOLR, an open source search platform built on Apache Lucene (Open-source enterprise search platform built on Apache Lucene) is used (as CKAN plugin) for the search functionality
