GT 4.2.0 Release Notes: WS MDS UsefulRP


1. Component Overview

WS MDS includes a Java package subsystem called UsefulRP which is home to (among other things) the Resource Property Provider component, otherwise known as the RPProvider Framework. The RPProvider Framework is an extensible software component that can be used to dynamically generate XML values for one or more WSRF Resource Properties in any given GT4 Java WSRF-Core compatible service.

2. Feature summary

Features in GT 4.2.0 WS MDS UsefulRP

  • Provides API and implementation for working with customized resource properties and information providers
  • Provides an implementation of a GLUE 1.1 schema compliant resource property
  • Provides sample resource property implementations for service developers to incorporate into their own services

3. Summary of Changes in UsefulRP

The RPProvider configuration file format has changed slighty. The ResourcePropertyProviderConfigArray structure contains an array of xml elements of the type resourcePropertyProviderConfig. In 4.0.x, the element name for each array item was "configArray"; in 4.2.x, the name has been changed to "resourcePropertyProviderConfiguration".

Structurally, the ResourcePropertyProviderConfigArray and its child elements have not been modified in any other way. Therefore, a search and replace for all instances of "configArray" with "resourcePropertyProviderConfiguration" should be all that is necessary to make 4.0.x RPProvider configuration files compatible with 4.2.x versions.
