1. Model: IVOA Quantity Data Model. (Quantity)

Authors : Gerard Lemso , UTYPEs tiger team
Date : 2013-04-26T13:43:50
Version : 0.x
Abstract : This is a sample data model. It contains the IVOA UML Profile and imports the IVOA_Profile data model with primitive types. It has some sample relationships etc to be used in documentation etc.
Diagram : The following diagram has been generated from the model using the GraphViz tool.
The classes and packages in the diagram can be clicked and are mapped to the descriptions of the corresponding element elsewhere in the document.

2.Model contents: Packages and Types

The following sub-sections present all packages in the model with their types. The packages are listed here in alphabetical order. Each sub-section contains a description of the package and a table containing its various features.
