Informatics, Technology and Standards
OneAquaHealth IEEE Global Hackathon: Informatics, Technology & Standards
Session 4 of the OneAquaHealth Innovation Series Leading to the IEEE OneAquaHealth Global Hackathon
TOPIC: Informatics, Technology & Standards
The OneAquaHealth Hackathon Learning Series continues on 27 August 2026 with its fourth session, Informatics, Technology & Standards, covering HL7 FHIR alongside a hands-on sandbox experience. Having moved from the project's scientific basis through One Digital Health and FAIR data principles, the series now turns to how those principles work in practice. Environmental sensor feeds, citizen observations, and health data rarely speak the same language — the problem set out in Track 7: Digital Health Standards, though it reaches well beyond that track. Any prototype drawing on more than one data source runs into it eventually.
Participants will gain practical experience navigating HL7 FHIR models within our dedicated sandbox environment, ensuring your innovations align with global One Digital Health and FAIR data principles. With the August 31 Hackathon registration deadline fast approaching, now is the perfect time to arm your team with the skills necessary to build breakthrough solutions and compete for the $3,000+ prize pool.
