Documentation and Training

  • LexEVS 6.x Installation Guide - outlines the supported configurations and technical installation instructions for LexEVS Vocabulary Services for caBIG®
  • LexEVS 6.x Loader Guide - intended for a LexEVS developer and provides information about the loaders provided, mapping, and how to create your own loaders using the loader framework
  • LexEVS 6.0 Javadocs - There are several parts to the LexEVS Javadocs to consult depending on what you are looking for. To download any of the Javadocs, go to the Javadocs section on the downloads page. You will find one download including all the Javadocs.
  • To interact with a LexEVS server that is hosting terminologies remotely, whether it be your own or the services at NCI, view the Distributed Javadoc online.
  • The Grid Data Service for LexEVS sits behind a caGrid interface. Most users do not reach this service via the Java API and in fact only a single method in the caGrid API is of interest. It can be found in the Grid Data Service Implementation.
  • No formal LexEVS Server training courses exist in the caBIG® Learning Management System (LMS) at this time
