Reliable validation of FHIR resources is required to ensure conformance with these specifications. However, validation in federated environments remains challenging due to heterogeneous infrastructures, limited terminology availability, and difficulties in establishing reproducible validation setups. Methods: This technical case report describes the design and implementation of a locally deployable FHIR validation service in the MII context. The system combines the HL7-maintained FHIR Validator with a configurable terminology service and a containerized deployment model. Structural and terminology validation are separated by design. Implementation guides and terminology resources are provisioned in a reproducible manner. The system supports both local terminology deployment and integration with existing institutional terminology services. Results: The proposed solution enables automated conformance testing of FHIR resource instances against MII implementation guides in local and federated environments. The service is provided as a reusable containerized validation component that can be integrated into development and data processing workflows, improving reproducibility, and reducing configuration effort across sites. Discussion: The results demonstrate that reproducible FHIR validation can be achieved through standardized deployment and controlled terminology provisioning. Remaining limitations are primarily related to incomplete or unavailable terminology content. Further work is required to evaluate the approach in production settings across data integration centers and to assess integration into data processing pipelines, including the handling and interpretation of validation results.<\/jats:p>","DOI":"10.3233\/shti260987","type":"book-chapter","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T14:47:45Z","timestamp":1789656465000},"source":"Crossref","is-referenced-by-count":0,"title":["A Locally Deployable FHIR Validation Service for Federated Health Data Infrastructures \u2013 A Technical Case Report"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2068-7765","authenticated-orcid":false,"given":"Julian","family":"Sa\u00df","sequence":"first","affiliation":[{"name":"Berlin Institute of Health at Charit\u00e9 \u2013 Universit\u00e4tsmedizin Berlin, Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0461-8185","authenticated-orcid":false,"given":"Alexander","family":"Kiel","sequence":"additional","affiliation":[{"name":"LIFE \u2013 Leipzig Research Centre for Civilization Diseases, University of Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9902-6459","authenticated-orcid":false,"given":"Joshua","family":"Wiedekopf","sequence":"additional","affiliation":[{"name":"Institute of Medical Biometry and Statistics, Section for Clinical Research IT, University of Luebeck and University Hospital Schleswig-Holstein, Luebeck, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7204-5329","authenticated-orcid":false,"given":"Julian","family":"Gruendner","sequence":"additional","affiliation":[{"name":"Medical Informatics, University of Erlangen-N\u00fcrnberg, Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2451-0027","authenticated-orcid":false,"given":"Maximilian","family":"Kurscheidt","sequence":"additional","affiliation":[{"name":"GECKO Institute, Heilbronn University of Applied Sciences, Heilbronn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","German Medical Data Sciences 2026: BIG DATA, small data, Your Data; Transitions in the age of biomedical AI"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI260987","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T14:47:46Z","timestamp":1789656466000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI260987"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,17]]},"ISBN":["9781643686875"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti260987","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,17]]}}}
