How to configure the VRE Management Service

The creation of every VRE that will operate in the context of a Virtual Organisation is supported by the VRE Management facility. The entire process of VRE creation and management is documented by the VRE Administration part of the Administrator's Guide.

However, a preliminary step is to instruct the VRE Management facility on how it should behave in the VO (e.g. what are the functionality that can be added to a VRE) by using the following two resources in the Information System (VO scope).

Functionality Resource

This resource models:

• the logical functionalities (organised in homogeneous classes) that should be presented to the VRE Designers for their VRE design;
• the per functionality configuration, e.g. data sources to be made available, algorithms to expose;
• the list of software components that will be actually deployed once a given functionality is selected;
• the list of additional resources that will be deployed at VRE creation time;

It is specified according to the following schema.
