5. Lesson 1: LexEVS Architecture LexEVS Infrastructure LexEVS 5.0 represents the next generation of NCI Enterprise Vocabulary Services. In this release, the LexBIG Java API and LexGrid model become the strategic EVS interfaces, replacing the legacy EVS API and the EVS 3.2 model. This evolution has been part of a plan spanning many releases of EVS which cover versions 4.1, 4.2, 4.2.1 and ultimately 5.0.

The unified design of LexEVS 5.0 no longer supports the EVS Model and EVS API. Both have been completely replaced with LexEVS components The convergence of LexEVS 5.0 components has introduced new naming of components:

12. Lesson 1: LexEVS Architecture Benefits of LexEVS 5.0 The 2008/01 model is updated to the 2009/01 LexGrid Model to provide more semantic consistency. LexEVS 5.0 introduces LexGrid-based Query-By-Example (QBE) services Unified OWL loader (Migration from the NCI OWL loader and a generic OWL loader to a single loader) to provide loading consistency. Updated to work with caCORE SDK 4.1 Consistent naming and release numbers for API and services. Optimized query execution (deferred restriction resolution) Ability to place an arbitrary number of restrictions on a search request, which are automatically combined by the runtime when on node or graph resolution Improved concept search Support of additional match algorithms Ability to place multiple search restrictions based on properties by type, name, value, or qualifier

13. Lesson 1: LexEVS Architecture Benefits of LexEVS 5.0 Improved graph navigation Provide navigation of arbitrary relationships within a specific distance, uni- or bi-directional navigation. Ability to place multiple search restrictions based on association name or qualifier. Introduction of a Data Grid Service Previously only an analytical grid service was available.
