  • Service Integration (Gateways APIs) for ONTOCHAIN applications,
  • Semantic Matching and Reasoning,
  • Energy-efficient and sustainable hosting infrastructure for the ONTOCHAIN software ecosystem and services

Objective B - To exploit the ONTOCHAIN infrastructure designed and implemented respectively through ONTOCHAIN OC1 and ONTOCHAIN OC2 for real life use cases that cover real need of individuals in terms of trustworthy data/services exchange and trustworthy content handling from various vertical domains/vital sectors of the European economy.

  • Be an important part of the ONTOCHAIN project and related ecosystem



Services will be provided remotely and will involve evaluation of the applications received, participation in remote consensus meetings as well as in the panel meeting to establish a ranking list of the evaluated proposals. All evaluators will be required to sign a non-conflict of interest declaration and a contract with the ONTOCHAIN project coordinator, before being accepted to evaluate a specific application.


Evaluators will be reimbursed for their time and effort on the basis of the number of proposals evaluated, with each proposal corresponding to a value of €50, considering 1 hour to evaluate each proposal.


Please note that this expression of interest to participate in the ONTOCHAIN Open Call 3 – Application and experimentation evaluation as an external expert is NOT binding and does NOT constitute any commitment to the ONTOCHAIN project.

The selection of the evaluators to support ONTOCHAIN in the evaluation of the Open Call will be taken at a later stage, since it depends on the number of received proposals, their origin, the domain that they target as well as the origin of the potential evaluators, their affiliations, their expertise and the balance between various criteria (e.g. gender, background, affiliation type, age, expertise etc.). Furthermore, it is mandatory to frequently change experts that support in the evaluations of proposals.
