This tool enables healthcare providers and organizations to efficiently modernize their data exchange processes, reducing manual effort while enhancing accuracy and compliance.

Key Features & Supported Conversions​

The iEHR Mapper offers a wide range of conversion capabilities, supporting legacy and modern formats alike:

  • FHIR ⇔ HL7v2 – Converts HL7v2 messages into structured FHIR resources and vice versa.
  • FHIR ⇔ C-CDA – Translates clinical documents into and from FHIR-based formats.
  • HL7v2 ⇔ JSON – Converts HL7v2 messages into lightweight JSON objects.
  • HL7v2 ⇔ XML – Ensures seamless translation of HL7v2 messages into XML format.

By automating these critical transformations, healthcare organizations can transition more efficiently towards FHIR-based workflows.

How It Works: Template-Based Conversions​

The iEHR Mapper operates using Liquid-based templates, which define flexible mappings between various healthcare data formats.

Key Template Features:​

  • Written in Liquid, a powerful and adaptable templating language.
  • Comes with pre-built templates, but users can create new or modify existing ones for custom conversion needs.
  • Supports complex data structures, ensuring robust interoperability for clinical workflows.

These templates empower organizations to fine-tune their data exchange processes while maintaining full FHIR compliance.

API Functionality​

The iEHR Mapper API provides REST-based endpoints to automate data conversion requests.

Key API Features:​

  • Accepts HL7v2, C-CDA, JSON, and XML inputs for processing.
  • Applies Liquid templates for custom data transformations.
  • Supports real-time processing for seamless integration.
  • Allows user-defined mappings for specialized workflows.

Developers can integrate the iEHR Mapper API into existing systems, ensuring efficient, scalable, and automated interoperability.
