Thanks to Keith for an excellent discussion on the Object Chronicles and the development of ISAAC (InformaticS Architecture ACceleration), a tooling environment that provides a reference implementation for Deriviate concepts build on top of SNOMED, LOINC, and RxNorm (SOLOR) terninology. For those that are interested in the development of ISAAC, the source code is available at OSEHRA ISAAC code repository. Documentation on ISAAC will be available at OSEHRA ISAAC Wiki in the near future.
For additional details on the discussion see the recording of the presentation.
Title: Object Chronicles as a Foundation for Integrated Informatics
Presenter: Keith E Campbell MD PhD, Director of Informatics Architecture at
U.S. Veterans Health Administration
Description: SNOMED CT changed its release formats in ~2010 to support
uniform representation of change over time across all components. Given the
interdependency between architectural layers (terminology, assertions,
rules, and more), having a uniform representation of change over time, and a
system of modules for managing dependencies between components is critical
to achieving manageability and scalability of informatics-enabled systems.
This presentation will describe our experiences implementing this uniform
representation by providing a persistent representation of object
