Kelvin Resource Names (KRN)¶

The Kelvin Resource Name (KRN) Registry serves as the centralized system for uniquely identifying various types of resources within the Kelvin Platform. It is conceptually similar to Uniform Resource Names (URN) or Amazon Resource Names (ARN), tailored for Kelvin's use.

Note

All KRN definitions are available in the Developer Tools KRN Reference.

This page outlines the core concepts and provides a few examples.

String Method¶

KRNs can be created directly from their string representation, as detailed in the reference page.

from kelvin.krn import KRN

# Generic KRN (parse from string)
generic_krn = KRN.from_string("krn:asset:my-asset")

SDK Method¶

The SDK provides some dedicated KRN classes to simplify creation and improve readability.

SDK KRNs	String Equivalent
KRNApp	`krn:app:app`
KRNAppVersion	`krn:appversion:app/version`
KRNAsset	`krn:asset:asset`
KRNAssetDataQuality	`krn:dqasset:data-quality:asset`
KRNAssetDataStream	`krn:ad:asset/datastream`
KRNAssetDataStreamDataQuality	`krn:dqad:data-quality:asset/datastream`
KRNAssetParameter	`krn:ap:asset/parameter`
KRNDatastream	`krn:datastream:datastream`
KRNJob	`krn:job:job/job-run-id`
KRNRecommendation	`krn:recommendation:recommendation-id`
KRNSchedule	`krn:schedule:schedule`
KRNServiceAccount	`krn:srv-acc:account-name`
KRNUser	`krn:user:user`
KRNWorkload	`krn:wl:cluster/workload`
KRNWorkloadAppVersion	`krn:wlappv:cluster/workload:app/appversion`

You can find these detailed in the reference page. An example of how they are used;

from kelvin.krn import KRNWorkloadAppVersion

KRNWorkloadAppVersion(node="my-node",workload="pvc-r312",app="pvc",version="1.0.0")
