This research on this paper by Evgeniy Krastev, Dimitar Tcharaktchiev, Petko Kovachev and, Simeon Abanos aims to design a worker’s occupational health assessment summary (OHAS) dataset that satisfies the requirements of an international standard for semantic interoperability in the use case for exchanging extracts of such data. The focus is on the need for a common OHAS standard at EU level allowing seamless exchange of OHAS at both cross-border and at the worker’s country of origin level.
