How To…Generate XSD Schemas from Existing MDM Repositories

October 2009 1

1. Business Scenario

Very often implementation projects require standard Inbound and Outbound interfaces that are based

on MDM repository structures. In order to reduce the implementation effort it would be useful to have

the possibility of generating an XML Schema (XSD) from an existing repository. Since this functionality

is still not available for MDM 7.1, we explain in this guide how to generate an XSD from an existing

MDM 7.1 repository using an eclipse plug-in that is delivered along with the document.

This is a standard eclipse plug-in which could be integrated with the Development Environment/Editor

and it provides a visual representation of the structures that form the part of the interfaces. The plug-in

could be downloaded here.

1.1 Use Cases

The solution provided here is relevant for the development of customer specific repositories that must

be quickly and smoothly connected to an existing landscape via XML messaging.

1.2 Limitations

The tool is an eclipse plug-in and hence, Eclipse must be installed in the system for using the

tool. The plug-in would work with NetWeaver Developer Studio version 7.1 based on Eclipse 3.3

and upwards.

Mappings of the remote keys of attribute values work only if the key mappings are activated for

the respective attributes.

The solution provided here is applicable only for SAP NetWeaver MDM 7.1 repositories.

Please check Appendix for a list of the supported data types.

2. Introduction

In this how-to guide we present a solution that is based on the standard MDM XML-Repository

description, and a JAVA application that generates an XSD interface description from an available

MDM Repository.

The plug-in is delivered as a zip file. The plug-in needs to be stored in the plugins directory of SAP

NetWeaver Developer Studio. This plug-in could be used for generating the XSD and it also provides a

visual representation of the schema structure. It also enables the user to double click and navigate into

different components.

CAUTION

The delivered plug-in is used to generate an XSD file and the choice of its usage is totally at the discretion of the user. SAP does not provide any kind of support in using

this tool.

3. Step-by-Step Solution

There are different steps to be followed for using the plug-in. The steps to install the plug-in and

generate the XSD file and then, importing into the MDM Console is explained below.

3.1 Extracting the plug-in and Installation

The delivered plug-in contains a jar file and 2 folders. The following steps explain how to install the

tool. ...

1. Extract the contents of the zip file into a folder in the local system.

2. Verify that a jar file (com.sap.nwrig.mdm.plugins_7.1.2.2.jar) and 2 folders

(com.sap.mdm.tech.mdm4j_1.0.0 and com.sap.mdm.schema_1.0.0) are present in the

extracted folder.

We need to copy the MDM Java APIs that is compatible with the MDM Server into the folder

com.sap.mdm.tech.mdm4j_1.0.0

Now the folders and the plug-in extracted from the rar file, along with the applicable Java APIs are

present in the extracted folder.

CAUTION

The default contents of the extracted folders should not be changed at all. The folder com.sap.mdm.tech.mdm4j_1.0.0 contains another folder META-INF with a meta file. The contents of this folder should not be changed at all as the functioning of the tool is based

on the information present in this file.

Note

When there is an upgrade of the MDM Server, the existing Java APIs (jar files) in the folder com.sap.mdm.tech.mdm4j_1.0.0 need to be replaced with the jar files

corresponding to the upgraded version.

3. Copy the contents of the extracted folder to the plugins directory of SAP NetWeaver

Development Environment. Now the plugins directory contains the jar file and 2 folders – one of

them containing the MDM java APIs. (If the IDE is already running, it needs to be restarted for

being able to use the plug-in).

3.2 Generating XSD from MDM 7.1 Repository

We can generate the XSD file and also see a pictorial representation in the SAP NetWeaver

Developer studio. This is done as explained below. ...

1. Create a New Project in the development Environment. Fill in the Name of the Project and other

details and click on Finish.

2. Create a folder inside the this project folder by right clicking on this project and then clicking on

New -> Folder. Select the parent folder, enter the name of the new folder and then click on

Finish.

3. Right click on this folder and select New -> Other. Locate “Mdm Wizards” and then Click on

“Generate XSD From Schema” under “Mdm Wizards”.

4. Enter the MDM Server URL and click on the button “Refresh Connection”.

5. All the available repositories in the MDM Server are displayed in the “MDM Repository” drop

down. Select the MDM Repository when prompted and wait for a few seconds. Enter the

Repository user and password (incase the repository has a password). Click on “Refresh

Connection”.

6. Select the Repository region when prompted and wait for a few seconds. The default XSD

File Name is “Schema” and if that needs to be changed, Enter the new name against the field

XSD file name. Click on “Next”.

7. Select the main tables in this screen for generating the XSD.

8. Click on “Finish” button for generating the XSD file.

The XSD file is generated and visualization is provided on the screen. The “Elements” and “Types”

could be seen on the screen and it also provides forward navigation. We can see more details by

double-clicking on the respective elements.

3.3 Exporting and Importing of the XSD into the MDM

Console

We need to export the XSD generated in the previous step and this XSD needs to be imported into the

MDM Console. ...

1. Right click on the folder created in the previous steps and choose Export. Choose “File System”

as the option in the next screen. Click on “Next”.

2. Click on the XSD file and also specify the target directory. Click on “Finish”.

In the destination directory, a folder would be created with the XSD file inside the folder.

The XSD file thus generated needs to be imported into the console for the specific MDM repository.

For achieving this, an Administrator needs to login to the MDM Console and add the file to the “XML

Schemas”.

The Schema description is used by the MDM Syndicator in the standard syndication process. More

details about this process and the MDM Syndicator could be accessed here at the help portal, under

Functional Components.

4. Appendix

4.1 Setting default values

We can set default values for the server URL and the user. For this, navigate to Window ->

Preferences -> Mdm Client Preferences, in the eclipse editor.

We can save the default MDM Server URL and also the default MDM user in here.
