---+ Registry Model for Applications
This page summarizes the models for applications within the "tiger team"

---++ 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 [[http://www.ivoa.net/internal/IVOA/InterOpOct2005ResReg/ApplicationsSoftwareMetadata.pdf][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. [[http://www.ivoa.net/Documents/Notes/CEA/CEADesignIVOANote-20050513.html][CEA]].
   * Can easily be extended to incorporate the registration of applications with new facilities - e.g. the [[http://plastic.sourceforge.net/][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 <br />

---++ CEA Model in detail

   
In addition for the UWS specification of a remotely invocable application the CEA model (with some enhancements) will be adopted. The UML for this model is presented below.

   * CEA Application: <br />

The expression of these models as XML schema is work in progress.
