Getting the list of custom attributes and system attributes present in RQM, RTC & RRC using their respective rest api/s

One answer

The RQM Reportable REST API does not support custom attributes as a resource type (see https://jazz.net/wiki/bin/view/Main/RqmApi#Resources_and_their_Supported_Op). However, custom attributes are included in test artifacts (see https://jazz.net/products/rational-quality-manager/api-doc-6.0/schemas/qm_xsd/elements/customAttributes.html).
