The purpose of this document is to collect, analyze, and define high-level needs and features of the National Cancer Institute Center for Biomedical Informatics and Information Technology (NCI CBIIT) caCORE LexEVS Release 5.1. This document focuses on the functionalities proposed by the product stakeholders and target users in order to make it a better product. The use-case and supplementary specifications document will detail how the framework will fulfill these needs.
Vision and Needs
The objective of this release of the LexEVS 5.1 is to support the Metathesaurus Browser project by enhancing search and sorting performance as well as RRF loader changes to more accurately reflect the data. In addition we will explore enhancements to the loader framework and provide a recommendation/implementation for value set/domain support.
