Below is a sampling of some of the MHS’ Open Source Software available to the public, at no cost.

What is OpenAHLTA?

Finds the same code in multiple different languages and gives the data a new "identifier" or code to create a consistent nomenclature
Supports achieving semantic interoperability for electronic health records

What is SEMOSS?

Java-based semantic open source analytics environment
Developed by the MHS to support evaluating existing health IM/IT solutions for transition to the future-state electronic health record
Allows users to load data and explore its surrounding context
Converts excel data into graphs for multi-dimensional analysis
Consumes data from multiple repositories in multiple formats
Includes interactive graphics, customizable charts, as well as roll-up and drill-down visualizations
Leverages cluster algorithms, transitivity, time-series latency analysis, and optimization analysis
