Registry Model for Applications

Goals

The v10 registry schema had no specific data model that described applications, so a new model has been proposed. The general goals of this model are to support;

General metadata about an application - e.g. Source code language. A suggested initial set of metadata were suggested at the October 2005 Interop meeting
Information about what VOStandards and data formats the application supports;
Concepts of
- Desktop application - with URIs to support automatic download and launching where possible
- Software library.
- Applications that can be run as services - e.g. CEA.
Can easily be extended to incorporate the registration of applications with new facilities - e.g. the PLASTIC system for desktop interaction between applications.

Application model

The UML model of how the new Application type fits into the registry schema is presented below
