Sharing clinical data using Distributed Ledger Technologies (DLT) is increasing in momentum. Fast Healthcare Interoperability Resources (FHIR) standard provides a standard based shared vocabulary and widely accepted mechanisms enabling healthcare providers to share patient data across institutions. Many DLT based solutions are capitalizing on these standards to enable trustworthy electronic health record sharing among institutions. In this paper, we present our preliminary work on capturing the semantics of the FHIR standard in smart contracts. We also discuss the appropriate data to mine from transaction logs in decentralized ledgers to find any anomalies and information misuses by leveraging these standards-based ontological concepts.
