Working with the Metadata Model: Tutorial

UNICOM Intelligence use the Metadata Model (MDM) to read and write metadata. The MDM is a COM component that is easily accessed using scripting languages such as mrScriptBasic and programming languages such as Visual Basic. The MDM is not an application, but rather an object-oriented repository that stores survey metadata. Do not try to access the metadata in an .mdd file directly; always use the MDM Document's interfaces.

This tutorial covers many of the basic principles involved in using the MDM and is based on mrScriptBasic overview.

Before starting the tutorial, read Market research data for an introduction to the market research data types, how they are handled by the UNICOM Intelligence Data Model, and the terminology used in this documentation.

For more details about the properties and methods of the MDM objects, see UNICOM Intelligence Data Model reference and MDM object reference.

Requirements

To run the examples in this tutorial, you need:

▪UNICOM Intelligence Data Model

▪UNICOM Intelligence Professional. The best tool for creating, editing, running, and debugging mrScriptBasic scripts is UNICOM Intelligence Professional. Alternatively, you can create mrScriptBasic scripts using a text editor such as Notepad, and then run them using mrScript Command Line Runner, which is supplied with the UNICOM Intelligence Data Model.
