Many DCCs have operational expertise in deploying software services, but lack expertise in deploying and exploiting FAIR services that use Semantic Web technology for machine actionability. Although local deployment is lightweight and non-invasive for institutional infrastructure, engineers are not yet familiar with the underlying web technologies of FAIR services. This poses a risk for delivering the FAIR foundation of a federated health data infrastructure that is ready for federated analytics, AI, and machine learning. This project is making deployment by institutional DCCs of FAIR services cost-effective, scalable, and sustainable by delivering 'FAIR Software as a Service' (FAIR-SaaS).
Semantic Web (SW) technology is a common implementation choice for software services that help
meet the machine actionability requirement of the FAIR principles. An example is the DCAT-based
FAIR Data Point (FDP) [
We present our first results of a project that aims to make deployment of FAIR services by institutional DCCs cost-effective, scalable, and sustainable by delivering ‘FAIR Software as a Service’ (FAIR-SaaS). FAIR-SaaS is centrally hosted software that is preconfigured and updated by FAIR specialists for institutional DCCs. The project starts with (i) common FAIR Data Point (FDP)2 configurations that DCCs can deploy to describe their resources for machines, (ii) grlc-inspired configurations facilitating DCCs to generate common APIs from FAIR metadata.

ceur-ws.org An early target is to simplify the processes for DCCs to contribute FDPs for data and compute capacity to the Dutch national health infrastructure, and comply with multiple existing and future common APIs. FAIR SaaS are straightforward to update for FAIR experts (e.g. grlc SaaS requires simple queries on FAIR metadata) who can guarantee convergence to international standards. The hypothesis is that FAIR SaaS provided by SURF, the Dutch national hosting organisation, which requires a minimal number of Semantic Web experts for maintenance, has a significant impact on the applicability, scalability, and sustainability of a health data infrastructure, demonstrating how a critical mass of FAIR (meta)data can be achieved for enhancing health care and life sciences.
A use-case has been defined with local health data project leaders from the LUMC, UMC Utrecht and Erasmus MC, to develop the overall architecture and concept of the service:
As a cardiologist I would like to see information on physical fitness (weight, stamina, blood pressure, etc.) for patients
planned for thorax surgery across two hospitals, such that I can screen patients based on their physical fitness for surgery and take decisions on timing of surgery and capacity planning. Patients that are not selected must undergo a fitness program.
architecture that has been defined in Figure 1, which resulted in the application Figure 1 FAIR-SaaS Business architecture, a conceptual architecture defined in Figure 2. From a overview of the need by the experts.
FAIR mindset, we have defined that these services do not need to be created by us but should be re-used where available and adjusted if necessary.
Semantic Web technology needed by IT personnel we concluded that the first services will be delivered in a docker container and that we need to set up a Virtual Machine (VM) Figure 2 FAIR-SaaS Application architecture, a conceptual image with these dockers pre-installed. The overview of the software services that are needed to address the VM is optional if docker knowledge is present need of the experts. at the specific IT department. We are currently combining existing tools to develop these features.
