Extracting RQM linked requirements from DOORS 9.x

When generating a report on RQM data using RPE you may want to include linked requirements. If the requirements are held in DNG then this is a relatively easy process. The complication is when the linked requirements are held in DOORS 9.x. In this situation the requirement data is extracted from DOORS Web Access (DWA).

The DWA requirement schema is not provided as part of RPE and is not discoverable. It must be loaded from a .xsd file. A sample DWA schema (which was downloaded from RPE Actual) is provided below.

This file should be saved locally and then when adding a data schema within RPE, the main.xsd selected as the schema file.

RQM will provide a requirement URI of the form:

https://[server]:[port]/dwa/rm/urn:rational::1-55bb46603d9c55be-0-10009-000bf60

Which can be used to dynamically configure the DWA data source.

Unfortunately, this only works for DWA requirements that are not linked to RQM!

When a requirement has an RQM link, it has a different schema. Within the above schema the main.xsd file must be modified with the following:

<xs:element name="RDF"> 
    <xs:complexType> 
      <xs:sequence> 
<xs:element name="Statement"> 
<xs:complexType> 
<xs:sequence> 
<xs:element name="subject"> 
<xs:complexType> 
<xs:sequence> 
<xs:element ref="oslc_rm:Requirement"/> 
</xs:sequence> 
</xs:complexType> 
</xs:element> 
</xs:sequence> 
</xs:complexType> 
</xs:element> 
<xs:element ref="oslc_rm:Requirement"/> 
      </xs:sequence> 
    </xs:complexType> 
  </xs:element>

Using the modified schema will then allow the requirement data to be extracted.
