Interoperability is an essential piece in the Cos4Cloud project to integrate the developed services and resources in the European Open Science Cloud (EOSC) ecosystem, as well as to find a ‘common vocabulary’ between citizen science observatories, which will make possible to reuse, share or integrate the data between different platforms.  

For this reason, all elements of the ecosystem (citizen observatories, services, data, software, etc.) will be built as independent services but they also will be parts of a single architecture. This modular approach is based on services that use standards and best practices to enable this ‘common language’ among the Cos4Cloud’s services, citizen observatories, and the EOSC.  

CREAF leads the community of practice in interoperability and citizen science. The community of practice was started in the Horizon 2020 WeObserve project and will be continued by the Cos4Cloud project, so all the lessons learned will be integrated and implemented throughout the project. 

In particular, CREAF & Secure Dimensions have developed STAplus, an extended data model for the SensorThings API that aims to standardise citizen science data and make it accessible, interoperable and reusable among different citizen observatories (COs) and services.

Bineo Consulting has implemented Darwin Core standard in Cos4Bio and Cos4Env. Darwin Core is usually used as the biodiversity standard in  Global Biodiversity Information Facility (GBIF) to share biodiversity information.


To ensure interoperability, Cos4Cloud’s technical work will be tested in interoperability experiments where the modules will demonstrate the capacity to work together in a seamless environment. EOSC requirements will also be tested to ensure the perfect fit of the services within the EOSC infrastructure. 

We are working on the interoperability, it will be available soon!

Community of practice

The community of practice aims to contribute to data quality, curation, and preservation of citizen science data and address privacy and licensing for citizen observatories sustainability. The community was consolidated in the Horizon2020 WeObserve project framework (December 2017-March 2021). During the project, this community did an experiment called Citizen Science Interoperability Experiment (CitSciIE) within the Open Geospatial Consortium (OGC) framework. This community of practice and the knowledge generated in the WeObserve project have been transferred to Cos4Cloud. Now, the community is open to the Cos4Cloud members and everyone interested in interoperability. The main objective is to organise discussions on how to build interoperability between the Cos4Cloud’s services and citizens’ observatories. Join us!
