Page History

If you are reading this page then you know that LexEVS is an enterprise wide terminology server. When first installed it comes with no terminologies loaded into it. This documentation will cover the means for loading most content types that can be loaded. LexEVS was built to accommodate a wide variety of input and meld it into a common form - unifying many common formats. This necessitates a variety of loaders, each used on a specific incoming format. These inputs are typically called terminologies or coding schemes.

LexEVS provides both a LexEVS administrative GUI and LexEVS loader commands to load terminologies.  While the LexEVS administrative GUI is very functional, a system administrator may prefer the command line interface because command scripts can be adjusted to increase memory and tune other java virtual machine settings to insure that loads of larger terminologies have adequate resources.  For example, a user may select a loading script, open it in an editor, increase the java heap size and PermGen memory, depending on the machine’s resources, and save the script before running with the appropriate options written into the command line. Still, the GUI can be convenient for loading smaller terminologies and, in many cases, works fine for loading moderately large terminologies like the NCI Thesaurus.  Loading terminologies requires some knowledge of the source of the terminology.
