Introduction
The Data Grid Service is based on the caGrid Data Service and allows programmers to pull data from the system (a target instance of LexEVS on the grid) based on queries that they write. These queries are sent in the form of CQL. The results are SOAP messages, which contain LexGrid XML.
The LexEVS Data Grid Service is a standard caGrid Data service based on the LexEVS 2010 Model.
For complete documentation on caGrid Data Services, see caGrid Data Service Documentation.
