link to configuration for a dataset

[vlimant]

looking at this again after some time, thinking that this would be ironed out by now, looks like things are not wired too properly just yet.

https://cmsweb.cern.ch/das/request?instance=prod/global&input=config+dataset%3D%2FRelValTTbar_14TeV%2FCMSSW_12_6_0_pre4-PU_125X_mcRun3_2022_realistic_v4-v1%2FMINIAODSIM

for example gives me a link to request manager and has the user decided what is what. can it be made that the exact only configuration that lead to the file creation is linked ? reqmgr has all the needed information. Is that "just" a matter of having a /config4dataset API somewhere ?

Jean-Roch, I'm not sure I understand your question. Could you please elaborate more on what exactly do you expect to be seen on DAS web page. So far, for this particular dataset, DAS provides three configurations:

• DigiPU_2021PU
• DQMConfigCacheID
• RecoNanoPU_2021PU

What do you mean by /config4dataset API, where it should be, which parameters it should accept, what it should return? The configuration files are part of CouchDB, so there is not specific API to get it and we can't add API to CouchDB. We only have the id of the document which holds content of the configuration. This is why on DAS page we return links to CouchDB documents.
