Re: EOCred: Identify the level of a credential

Thanks for digging in to get more precise on level here.

I like how the SCQF reasons about levels of accomplishment. A Credential
can recognize a level of accomplishment, a level of performance, or both. A
Course could be "at" a level of accomplishment in terms of difficulty or
prerequisite knowledge & skills. These are good use cases to target, and if
I think of "educationalLevel", this would be the sense of level that would
fit best, versus "level of performance", even though it would be possible
to split hairs further between the two categories I started with, which we
could abbreviate to "accomplishment level recognized" and "accomplishment
level required".

This vocabulary's ability to describe level of accomplishment should be
distinct from trying to talk about level of performance and not use the
same property, in my opinion.

Fritz,
I'm a little wary of "A string, term or URL". That's amazingly broad to the
point where it would likely make it very difficult to serve the comparison
use cases.

What feels important to me about understanding the level of accomplishment
of a credential is its position relative to other credentials, learning
opportunities, etc. I am not confident I get that across a range of
credentials unless they all use specific URLs pointing to level definitions
like the ones from the SCQF.

On one hand, one string property is nice and simple, on the other hand, it
doesn't serve comparison use cases well unless all the credentials you'd
like to compare use a very specific scheme established outside the scope of
this vocabulary known to the consumer.

Maybe I changed my mind on using alignment, particularly because
AlignmentObject already has the "alignmentType" property, which includes
"educationalLevel" as an option. We could suggest something like this,
adding a numerical levelNumber property and using a URL either for
educationalFramework or targetUrl (a little wary of targetUrl because I
would think that should represent a URL of the exact level that alignment
is desired for, but maybe somebody can ease my mind on this point)

{
"@context": "http://schema.org",
"@type": "Credential",
"alignment": [{
"educationalFramework": "http://pinballsorcerers.org/levels/2",
"alignmentType": "educationalLevel",
"levelNumber": 2
},
{
"educationalFramework": "
https://ec.europa.eu/ploteus/content/descriptors-page",
"alignmentType": "educationalLevel",
"levelNumber": 7
}
]
}

It does seems like we're not going to be able to model this nearly as well
to serve comparison use cases with a bare text string. Only human eyeballs
could make sense of the difference between

"educationalLevel": "Pinball Wizard Level 1: Nub" and "educationalLevel":
"Pinball Wizard Level 6: Ultimate Extra Baller"
