What is the URL to fetch components from RQM local stream?

You will need to query for them. You can discover the OSLC Service Provider Catalog for configuration management from ETM's rootservices document (e.g. https://localhost:9443/qm/rootservices). Then use standard OSLC service discovery (see the OSLC Core specification linked to from https://open-services.net/specifications/) to discover the OSLC query capability for configurations. A GET on the query base of that query capability will allow you to query for ETM configurations. You can find more information about OSLC Query from the OSLC Query 3.0 specification linked to from https://open-services.net/specifications/.

I deployed an ELM 6.0.6.1. A GET on https://localhost:9443/qm/rootservices gave a response that included:

  <!-- Configuration Management service catalog -->
  <oslc_config:cmServiceProviders
          xmlns:oslc_config="http://open-services.net/ns/config#"
          rdf:resource="https://localhost:9443/qm/oslc_config/catalog"  />

Note that ETM declares multiple OSLC service provider catalogs in its rootservices. The one you want for configuration management uses oslc_config:cmServiceProviders .

A GET on the SPC at https://localhost:9443/qm/oslc_config/catalog with header Oslc-core-version=2.0 gave a response that included:

  <rdf:Description rdf:nodeID="A19">
    <oslc:resourceType rdf:resource="http://open-services.net/ns/config#Configuration"/>
    <oslc:queryBase rdf:resource="https://localhost:9443/qm/oslc_config/resources/com.ibm.team.vvc.Configuration"/>
    <oslc:resourceShape rdf:resource="https://localhost:9443/qm/oslc_config/resourceShapes/com.ibm.team.vvc.Configuration"/>
    <dcterms:title rdf:parseType="Literal">Default query capability for Configuration</dcterms:title>
    <rdf:type rdf:resource="http://open-services.net/ns/core#QueryCapability"/>
  </rdf:Description>
    

A GET on the query base (without any oslc.where) gave the RDF shown below. In my case, I had only create a single ETM project area and enabled it for configuration management. I had previously found that ETM did not support specifying process:projectArea in either the component query capability or configuration query capability, so it appears you cannot limit the query to a specific project area.
