Is "PURL" (all caps) considered an incorrect abbreviation?

[joeattardi]

All throughout the spec, the abbreviation "purl" (all lowercase) is used. I was wondering, is this intentional - is all uppercase ("PURL") or a mix ("pURL") considered incorrect when referring to a package URL?

@joeattardi, the value that begins with pkg: is more important. I have tools that use purl as a "bom-ref" and other ids for uniqueness.

I have the same question.

I see purl being used. Example: https://tomalrichblog.blogspot.com/2023/12/the-naming-problem-isnt-complicated-if.html

And PURL. Example: https://resilientcyber.substack.com/p/whats-in-a-name

Would be great to give guidance on the correct naming usage.

...and here is another example with all caps, from people who should know:
CVEProject/cve-schema#173
These is the kind of pesky detail that does not help convincing decision maker that a project is serious.

IMHO we should not be pedantic about case: you can use any way you like, PURL is not case sensitive.

I like to use PURL, all uppercase when I mention it in writings. But when using it in code for a variable or field name, I use purl all lowercase. YMMV.

Hi @joeattardi . I'm pleased to note that on 2024-10-11, Ecma TC54-TG2 approved the use of Package-URL and PURL. See https://github.com/Ecma-TC54/tg2/blob/main/meetings/2024-10-11.md

If this answers the question you raised, please feel free to close this issue -- and if not, please advise what remains to be addressed. Thank you!

@johnmhoran Thanks, that looks like a definitive answer to my question - PURL is OK!
