NCI plans to retire the LexEVS 5.0 terminology server on May 1, 2012. It has been deprecated since late 2010, and previous announcements have encouraged users to migrate to the newer LexEVS 5.1 or 6.0 servers. If you still use the 5.0 server, please contact us by email so that we are aware of your needs and can help you migrate.
Information about migrating can also be found on these wiki pages:
This is the wiki home page for the EVS tools and program. EVS developers may edit these pages and any user may add a comment. This wiki has technical and product information for EVS as follows.
NCI Enterprise Vocabulary Services (EVS) provides controlled vocabulary that is the semantic base for caCORE, and caBIG® tools and collaborations as well as Semantic Infrastructure. EVS is a project of the National Cancer Institute Center for Biomedical Informatics and Information Technology (NCI CBIIT). EVS activities include terminology development; terminology licensing; software development and licensing; and operations support. Projects center on development and maintenance of vocabulary and servers.
EVS develops and provides operations support for two broadly used vocabulary sources for cancer research: the NCI Thesaurus (NCIt), a cancer-focused terminology, and the NCI Metathesaurus (NCIm), a mapping of concepts to terms in multiple vocabularies.
EVS has also developed tools to support collaborative community-based ontology development including NCI Protégé, and develops and maintains the NCI Term Browser.
In addition, EVS licenses and serves third party terminology as needed to meet NCI and caBIG® requirements. From its beginning, EVS has sought to address the broad spectrum of terminology needs at NCI.
LexEVS 6.0 is the current release of EVS Enterprise Vocabulary Services (EVS). For detailed information about the current release and earlier releases refer to the LexEVS Wiki.
The underlying software code, object model, use cases, and user documentation are available for use under an open-source license. Developers are encouraged visit the EVS download page for the relevant files and licensing information.
Files from caCORE EVS version 5.x and earlier are made available for download from the EVS Archives. Note that the 4.x and 5.x license terms still apply.
