 Hi Everyone,


We have a requirement to create a link for reference term using api. 

What we are  doing now is the following:
POST to: <RM_SERVER_ADDRESS>/rm/links

headers:
{'DoorsRP-Request-Type': 'private', 
'Content-Type': 'application/rdf+xml', 
'oslc.configuration': '<GC_SERVER_ADDRESS>/gc/configuration/145', 'net.jazz.jfs.owning-context': '<RM_SERVER_ADDRESS>/rm/rm-projects/IrrUYfOtEealZ_zm_SstCA/components/_na2ccCWuEeu1LM6pSS3uxg',  
'X-Requested-With': 'XMLHttpRequest'}

<rdf:RDF xmlns:rm="http://www.ibm.com/xmlns/rdm/rdf/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">

<rm:Link rdf:about="">

<rdf:subject rdf:resource=""/>

<rdf:object rdf:resource="_"/>

<rdf:predicate rdf:resource="http://www.ibm.com/xmlns/rdm/types/ArtifactTermReferenceLink"/>

<rm:suspectSubjectCleared/>

<rm:suspectObjectCleared/>

<rdf:type rdf:resource="http://www.ibm.com/xmlns/rdm/rdf/Link"/>

<rdf:value rdf:datatype="http://www.w3.org/2001/XMLSchema#string"></rdf:value>

</rm:Link>

</rdf:RDF>


We are calling this api to 'n' artifacts in a loop

This POST call is working and creating reference term links for 'n' artifacts , but when we try to update same 'n' artifacts

again then it is not creating and hanging around 5th call , we are not getting error as well in return.


Please help us !


Thanks in advance,

Jyothsna.

This is a private API

Hi Ian,


Thanks for reply. Can't we use Private apis? Is there any restrictions to use?

Thanks,
Jyothsna.

Hi Jyothsna,

I think this issue happened because of the way RM API handles concurrent requests. To avoid this, create a batch of link objects in memory and call the rm/links endpoint once to create all of them. 
Following the code:
import requests

def create_reference_term_links(rm_server_address, gc_server_address, artifacts):
  """Creates reference term links for the given artifacts.

  Args:
    rm_server_address: The address of the RM server.
    gc_server_address: The address of the GC server.
    artifacts: A list of artifact IDs.
  """

  # Create a batch of link objects in memory.
  link_objects = []
  for artifact_id in artifacts:
    link_object = {
      "subject": "http://%s/_%s" % (rm_server_address, artifact_id),
      "object": "",
      "suspectSubjectCleared": True,
      "suspectObjectCleared": True,
      "value": ""
    }
    link_objects.append(link_object)

  # Call the rm/links endpoint once to create all of the link objects in the batch.
  response = requests.post(
    "%s/rm/links" % rm_server_address,
    headers={
      "DoorsRP-Request-Type": "private",
      "Content-Type": "application/rdf+xml",
      "oslc.configuration": "%s/gc/configuration/145" % gc_server_address,
      "net.jazz.jfs.owning-context": "%s/rm/rm-projects/IrrUYfOtEealZ_zm_SstCA/components/_na2ccCWuEeu1LM6pSS3uxg" % rm_server_address,
      "X-Requested-With": "XMLHttpRequest"
    },
    data="".join([
      "".join([
        "<rm:Link rdf:about=\"\">",
        "<rdf:subject rdf:resource=\"%s\"/>" % link_object["subject"],
        "<rdf:object rdf:resource=\"\"/>",
        "<rdf:predicate rdf:resource=\"http://www.ibm.com/xmlns/rdm/types/ArtifactTermReferenceLink\"/>",
        "<rm:suspectSubjectCleared/>",
        "<rm:suspectObjectCleared/>",
        "<rdf:type rdf:resource=\"http://www.ibm.com/xmlns/rdm/rdf/Link\"/>",
        "<rdf:value rdf:datatype=\"http://www.w3.org/2001/XMLSchema#string\">%s</rdf:value>" % link_object["value"],
        "</rm:Link>"
      ] for link_object in link_objects),
      "</rdf:RDF>"
    ])
  )

  # Wait for the RM API to finish creating the link objects.
  response.raise_for_status()

  # Check the response content to make sure that all of the link objects were created successfully.
  response_content = response.content.decode("utf-8")
  if "error" in response_content:
    raise Exception("Failed to create reference term links: %s" % response_content)

if name == "main":
