Supported Platforms

The servers listed in the table below represent hardware that LexEVS has been tested on.

Warning

These servers do not represent the minimum hardware required for loading any terminology. The LexEVS Local Runtime performs adequately in an environment with a memory limit of 4GB, but users cannot load larger OWL files, such as the full NCI Thesaurus or NCI Metathesaurus, in such environments. Users will have to load such terminologies on more powerful hardware. There does not exist a list showing the minimum hardware for a given terminology. Please refer to the VKC Support page for more information.

Prerequisite Software

Required Software - Not Included in LexEVS

You must download and install required software which is not included with the LexEVS distribution.

Where you have more than one choice you simply need to decide which one product you would like to use with your deployment of LexEVS.

Supported versions of other related technologies can be found listed in the NCI CBIIT Technology Stack pages. Differences between the LexEVS supported software and the NCI CBIIT Technology Stack are negotiated by the LexEVS development team with NCI.
