Komet Overview

Komet is the authoring and transformation environment within IKE, designed to let experts create, refine, and share healthcare knowledge in a way that is accurate, reusable, and standards-aligned. It integrates existing sources like SNOMED CT®, LOINC®, RxNorm, and GUDID with new inputs, giving users the ability to import, structure, extend, and export content in formats that fit their systems. By reducing redundant work and minimizing errors, Komet ensures knowledge can flow seamlessly across applications to power decision support, strengthen data quality, and enable better outcomes across the healthcare ecosystem.

What is Komet?

Komet is an open-source environment designed to manage, harmonize, and extend disparate knowledge standards, which enables users to import, transform, extend, and export content into a common model. 

Komet Use Cases

Komet provides several benefits to a wide range of stakeholders throughout the healthcare ecosystem.

Terminology Management

Use Komet to author, curate, and maintain terminology assets by bringing together SNOMED CT®, LOINC®, RxNorm, GUDID, and other sources into a consistent, reusable knowledge base.

Cross-Standard
Knowledge Creation

Build new knowledge artifacts that connect across multiple standards, making it easier to describe medical products, lab tests, and clinical data in ways that are consistent and interoperable.

AI and LLM Enablement

An icon representing artificial intelligence or machine learning, with a brain connected to nodes, on a purple background.

Ground large language models in structured, standards-aligned knowledge to improve accuracy, reduce hallucinations, and provide trusted answers in regulatory,
clinical, and research contexts.

Regulatory & Policy
Support

Generate reusable, validated data elements and mappings that help agencies align policies, improve compliance monitoring, and reduce duplication of effort.

Clinical & Public Health Decision Support

An icon of a medical report with a magnifying glass over it on a purple background.

Enable decision-support systems to draw on harmonized knowledge, improving the consistency of test coding, medication records, and device data used in patient care and public health surveillance.

Knowledge Sharing
& Reuse
