I want to add constraint of relation type for asset type by RAM API, but I cannot find that operations neither by java client nor web service API. I can create relation type, can create asset type, but no idea to connect them together. Have any idea? Thanks.

Unfortunately we have not had the time to fully flush out all the admin functions into API. We do not have a simple way to accomplish adding a relationship constraint to an Asset Type. However the constraints are stored in the Asset Type configuration. This can be set via the API.

I would recommend setting up your asset type in the UI just as you would like it. Than writing a test case that gets the Asset Type from the session and prints it out.

RAMAssetType type = session.getAssetType("AAA");

String config = type.getConfiguration();

System.out.println(config);

For example I have an Asset Type that requires a relationship of type "documentation" to an Asset of type Specification.

<?xml version="1.0" encoding="UTF-8"?>

<com.ibm.ram.common.emf:AssetTypeConfiguration xmi:version="2.0"

    xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:com.ibm.ram.common.emf="http:///com/ibm/ram/common/emf.ecore">

  <constraints xsi:type="com.ibm.ram.common.emf:RelationshipGrouping">

    <constraints count="1" relationship="documentation" requiredAssetType="classif/assetTypesSchema.xmi#specification"/>

  </constraints>

</com.ibm.ram.common.emf:AssetTypeConfiguration>

Once you have the XML that describes the AssetType constraints you would like you can set this value in the configuration when programmatic creating a new type...

RAMAssetType type = session.createAssetType("New Type");

type.setDescription("This is a test type created to show how to programtically create a relationship constraint");

StringBuffer config = new StringBuffer("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");

config.append("<com.ibm.ram.common.emf:AssetTypeConfiguration xmi:version=\"2.0\"\n");

config.append("    xmlns:xmi=\"http://www.omg.org/XMI\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:com.ibm.ram.common.emf=\"http:///com/ibm/ram/common/emf.ecore\">");

config.append("  <constraints xsi:type=\"com.ibm.ram.common.emf:RelationshipGrouping\">");

config.append("    <constraints count=\"1\" relationship=\"documentation\" requiredAssetType=\"classif/assetTypesSchema.xmi#specification\"/>");

config.append("  </constraints>");

config.append("</com.ibm.ram.common.emf:AssetTypeConfiguration>");

type.setConfiguration(config.toString());

		

session.put(type, new RAMStatusMonitor(){

	@Override

	public void appendStatus(Object targetObject, int severity, int code, String message, Throwable exception) {

		System.out.println(severity + " - " + code + " " + targetObject + ": " + message);

		if(exception != null) exception.printStackTrace();

	}}

);

There is an enhancement to better expose this functionality in the API...
