FHIR RDF: Where Semantic Web Meets Healthcare Data
FHIR RDF provides a Semantic Web representation of FHIR resources, opening healthcare data to SPARQL-based queries and reasoning. It's not mainstream in 2026 but has real use cases in research and multi-source data integration. Where FHIR RDF shines 1. Research data federation. Multiple study sites contribute FHIR resources; RDF representation enables federated SPARQL queries across […]
FHIR Terminology Browsers: 4 Tools for Code Exploration
Clinicians and analysts frequently need to look up SNOMED CT concepts, LOINC codes, and ValueSet expansions. Four terminology browser tools cover most 2026 use cases. **1. Ontoserver Snowstorm.** CSIRO's terminology server ships with a browser UI. Supports full SNOMED CT hierarchy, ValueSet expansion visualization, and FHIR `$expand` operations. Best for enterprise deployments. **2. SNOMED International […]
FHIR `$lookup`: Terminology Operation Patterns That Work
The FHIR `$lookup` operation returns metadata about a coded value — display name, definition, properties, designations. Four patterns cover most production use cases. Pattern 1: Display name resolution on read. When a client reads a Coding element (e.g., Observation.code), the code is present but display might be stale or missing. Client calls $lookup to get […]
FHIR Server Deployment: Kubernetes Patterns for 2026 Production
Deploying a FHIR server on Kubernetes in 2026 involves a mix of standard cloud-native patterns and FHIR-specific considerations. The five patterns below cover most production deployments. 1. StatefulSet with persistent volume for FHIR server + Postgres. The FHIR server itself is often stateless (state lives in Postgres), but Postgres is stateful. Use StatefulSet for Postgres […]
FHIR Server Monitoring: 6 Metrics That Predict Production Issues
Prometheus metrics for FHIR servers should track more than CPU and memory. Six operational metrics predict production incidents before they become outages. 1. $validate pass rate. Percentage of writes passing validation. Dropping <95% signals upstream data quality regression. Track per resource type. 2. Postgres connection pool utilization. FHIR write throughput is often gated by connection […]
FHIR Server Selection Checklist: 8 Questions Before You Sign
Signing a FHIR server contract without asking eight specific questions is where teams lose 6 months to unpicked-up-on gaps. The list below is what production teams actually verify before commitment. **1. Does it pass Inferno for your target profiles?** Not marketing claims — verified conformance against US Core, Da Vinci PDex, or whichever IGs matter. […]
