[RM] Creation of Baseline in Non-GC RM Project using OSLC
Hello,
I am looking for some examples to create baseline for non-GC projects of DNG PA.
I read this : https://jazz.net/forum/questions/249582/is-there-a-rest-api-for-dng-to-create-a-local-streamcomponent-and-baseline
Tried for Baseline : Response is 202 Accepted.
But Baseline was not created. Any leads here ?

FORUM ADMINISTRATOR / FORUM MODERATOR / JAZZ DEVELOPER Your POST body is very sparse. Try doing a GET on the stream you want to create a baseline from, and using the RDF from that with changes to the RDF types, title, description and POST that modified content.
Comments Did the get and performed the POST Operation. Its stating method not allowed 405

Still not successful

Performing GET on location header leads to "Not Found"

FORUM ADMINISTRATOR / FORUM MODERATOR / JAZZ DEVELOPER POST to what URI? You cannot POST to the stream.
See https://docs.oasis-open-projects.org/oslc-op/config/v1.0/psd01/config-resources.html#shape-stream.
So the sequence would be:
Comments URI : https://xxx/rm/cm/stream/_ovO15tKLEeuaG5VmJAdw1w/baselines
Body
<oslc_config:Baseline>
<dcterms:description>Description</dcterms:description>
<dcterms:title rdf:parseType="Literal">Power BI - example Initial Stream</dcterms:title>
<prov:wasDerivedFrom rdf:resource="https://xxx/rm/cm/stream/_ovO15tKLEeuaG5VmJAdw1w" />
</oslc_config:Baseline>
Even though Response is 202 and GET on location header
Response os Not found on activity.
What headers are you including in the POST?

Comments Most likely the POST request body contains incorrect data. Note that some objects need to have a about URI that is NOT NULL. E.g. about="https://nowhere.net/". It might not matter what the URI is, it just has to be a URI and can not be empty.

In Turtle, the POST request is:
@prefix acc: <http://open-services.net/ns/core/acc#> . @prefix process: <http://jazz.net/ns/process#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix dcterms: <http://purl.org/dc/terms/> . @prefix ldp: <http://www.w3.org/ns/ldp#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix oslc_config: <http://open-services.net/ns/config#> . @prefix prov: <http://www.w3.org/ns/prov#> . @prefix oslc: <http://open-services.net/ns/core#> . In essence, the subject is a blank node. As Ralph suggests, try a proper URI for the suibject. |
