OCL Online

Software-as-a-service, powered by the OCL TermBrowser and Terminology Service, allows you to search and manage healthcare terminologies and metadata with powerful features for beginners and advanced users.

Explore reference terminology

Search and navigate healthcare terminology and metadata published and maintained by leading standards organizations including CIEL, PEPFAR, LOINC, WHO, and many more, as well as our global community.

Re-use standardized content

Work with content from reference terminologies easily in your own terminology resources, such as EMR data dictionaries and value sets and create mappings from your own local content.

Create and edit your own concepts

Create Concepts with synonyms, language variants, mappings, and other custom metadata attributes, then create your repositories or download your content, including in FHIR format.

Build and maintain dictionaries

Gather and configure sets of relevant content for your systems, and track changes over time.

Create mappings to your concepts

Specify relationships between and across concepts, like maps to standard terminologies or questions and answer sets.

Side by side comparison of content

Compare differences between versions of content or between codes from separate terminologies

API-enabled

OCL Online is fully API/FHIR enabled, because it is backed by the OCL Terminology Service.

“Partners In Health is now managing our OpenMRS concept dictionary with OpenConceptLab for implementations at 4 country sites (Haiti, Liberia, Mexico, Sierra Leone). This is a milestone in supporting many countries, multiple languages, and a global PIH team. It is a transparent and consistent way to share our dictionary, and will save deployment time. It's been a long process with much support along the way. It exemplified the power of open source, teamwork, and the international OpenMRS community. Our hope is that other community members are already using OCL or moving in that direction.”
