{multi-excerpt:name=LexEVS6.0a}LexEVS includes the following components:
* Terminology Server - An enterprise level terminology server
* Java API - A Java interface based on the LexGrid Object Model
* REST/HTTP Interface - Offers basic HTTP based query mechanism from which results are returned in either XML or HTML formats
* SOAP/Web Services Interface - Provides a programming language neutral Service-Oriented Architecture (SOA)
* Distributed API - A Java interface based on the LexGrid data model and relies on a LexEVS Proxy and *Distributed LexEVS Adapter to provide remote clients access to the native LexEVS API
* LexEVS Grid Services - An interface which uses the caGRID infrastructure to provide access to the native LexEVS API via the caGRID Services
* Developers GUIs - Server administration, query testing, and value set development can be performed by a developer
The name LexEVS highlights the merging of LexGrid, LexBIG, and EVS technologies and designates an entire suite of tools. In this suite, LexGrid is the underlying model for standard storage of controlled vocabularies and ontologies. The LexBIG API is the set of services that EVS adapters use to store and retrieve terminology metadata. LexEVS APIs are a combination of convenience methods and the LexBIG API (combining LexBIG and the EVS adapters into one set of services). For detailed information, refer to the [LexEVS architecture overview|LexEVS:LexEVS 6.0 Architecture].
After you have a chance to get familiar with the LexEVS suite, consider looking through the [LexEVS:LexEVS 6.0 Functionality Overview]. This lays out everything that can be done from a developer's or ontologist's point of view.
h2. Installation and Downloads
The [installation overview|LexEVS:1 - LexEVS 6.0 Installation Overview] provides an introduction to the different environments that can be installed. Refer to the [LexEVS:LexEVS 6.0 Installation Guide] for more information.
The [LexEVS:LexEVS 6.0 Installation Options] identifies the download files for each LexEVS environment that can be installed (Local Runtime, Distributed, and Grid Services).
The [LexEVS:LexEVS Widget Library] lists many widgets that have been developed for use by particular customers. These widgets have been found to be potentially useful to a wider audience. Each widget has a description for you to use in deciding if you'd like to dig deeper and find out the usefulness of the widget in your application.

* 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|LexEVS:LexEVS 6.0 Installation Options#LexEVS Source Code, JavaDocs, and Examples] on the downloads page. You will find one download including all the Javadocs.
** If you have a local application accessing a Local Runtime, view the [Local Runtime Javadoc|http://informatics.mayo.edu/LexGrid/downloads/LexEVS_60_JavaDocs/LexEVS_Local_Runtime/] online.
** 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|http://lexevsapi60.nci.nih.gov/lexevsapi60/docs/] online.
** If you are using the Grid Analytical Services, view the [Grid Analytical Services Javadoc|http://informatics.mayo.edu/LexGrid/downloads/LexEVS_60_JavaDocs/LexEVS_Analytical_Grid_Services/] 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|http://software.cagrid.org/caGrid-1.3-javadocs/gov/nih/nci/cagrid/data/service/DataServiceImpl.html].
No formal LexEVS Server training courses exist in the caBIG® Learning Management System (LMS) at this time.
