Each Resource object returned is described as a Map of string key's to string values.

The keys are property names of the corresponding type schema on the StarTeam platform, their values are String representations of their matching underlying metadata types.

Note that every map contains a generic key value pair called a "ResourceID".

ResourceIDs are unique server wide descriptors of the underlying artifacts they represent.

So, a User ResourceID is the StarTeam UserID, a Project ResourceID is a projectID, a ChangeRequest ResourceID is a ViewMemberID, etc...

The combination tuple {ResourceID, TypeID} can pretty much locate any starteam artifact in the system.


For the sake of completeness, here is the source code for the Resource class



import java.util.HashMap;
import java.util.Map;

import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;

public class Resource extends HashMap<String, String> implements Serializable {

* Every resource has a unique "ResourceID" which is equivalent to the StarTeam id of the resource
* for example, project "ResourceID" is equal to project id.
* changerequest "ResourceID" is equal to viewmemberid
* client applications must send the resource id as part of the message
* for the artifact to be successfully recognized
private static final long serialVersionUID = -2384489572937175702L;

public Resource() {

public Map<String, String> getStructure() {
return this;

public String put(String key, String value) {
if (key == null || value == null ||
value.equals("{}") || value.contentEquals(Transformers.nullObject)
|| (value.startsWith("[;@")))
return null;
return super.put(key, value);



I wrote the test example by leveraging the .class directly in my eclipse project.

However, any client side developer can leverage this class source definition (above) to achieve the same results.

The important takeaway is that the streaming 'signature' of STarTeam resources, embodied by this REST api

is a reasonably flat XML or JSON structure of key-value pairs.

The keys are property names, the values are String representations of the property values.


However,  if the values are themselves complex  data structural StarTeam types, then they are represented as Resource objects (i.e. a map of key-value pairs) 

a good example would be a StarTeam Enumerated Value or a StarTeam Link Value.

In this case, a higher level type (e.g. a Trace) maps a String key (e.g. SourceLinkValue) to a Resource, i.e a set of key value pairs themselves.
