Hi Greg!
I'd propose to go a bit further and make
Thing->Intangible->Audience->PeopleAudience->EducationalAudience
 
PeopleAudience type proposed in http://www.w3.org/wiki/WebSchemas/Audience already contains properties for defining age range: minAge and maxAge.
So you don't need typicalAgeRange property anymore and don't need to handle it as text, because there is a good complex structure.
 
A final example will look so:
<div ...>
    <div itemprop="audience" itemscope itemtype="http://schema.org/EducationalAudience">
        <span itemprop="educationalRole">Teacher</span>
        Recommended age: <span itemprop="minAge">14</span>-<span itemprop="maxAge">18</span>
    </div>
</div>
 
We get +1 nesting level, but this is a small price for current and future audience scheme flexibility plus avoiding semantic duplicates in properties.

 LRMI proposal contains intendedEndUserRole property with the same purpose,
 contaning some text (which is also a soft enum).
 Looking at this again ... in terms of "what can we do now for
 integration, while still moving quickly towards including LRMI 1.0"?

 From LRMI, as you say, http://www.lrmi.net/the-specification

 * intendedEndUserRole schema.org/Text The individual or group for
 which the work in question was produced. Ex: “student” Ex: “teacher”

 Would a minimalistic improvement here be, to allow intendedEndUserRole
 to also (as an alternative) point to a thing of type
 http://schema.org/Audience ?

I think this might make sense, or, we could do as is suggested on the
wiki page:

Create a Thing->Intangible->Audience->EducationalAudience

That EducationalAudience could initially have a single added term on top
of what Thing provides called "educationalRole" (or similar). That
educationalRole would take a text value that specifies the specific role
that the group identified by EducationalAudience.

That would mean that anyone who has already begun marking up content
with LRMI would need to modify their markup from:

<span itemprop="intendedEndUserRole">Teacher</span>

to:

<span itemprop="audience" itemscope itemtype="http://schema.org/EducationalAudience">
<span itemprop="educationalRole">Teacher</span>
</span>


(that assumes we get rid of intendedEndUserRole in favor of the Audience
intangible)


If we did what you suggest ("allow intendedEndUserRole to also (as an
alternative) point to a thing of type http://schema.org/Audience") what
would it look like with a Audience intangible in the place of the
intendedEndUserRole value? I might be misunderstanding some aspect of
the syntax but it would seem it would be more nested than the example I
have above? Am I missing an easy way to model that?


Thanks!

Greg
