Hi,

I have a couple of questions:

TypicalAgeRange--Is there value in knowing that materials may be of
interest level for one age level, but written at another age level? I
am thinking of ESL materials that are written at a very easy reading
level, but are intended for adults. How would materials such as this
be treated in this schema?

isBasedOnURL--Is it possible to list tags multiple times? An example
would be some material created from 3 different original links. Does
the schema address repeatability or is it always assumed that all tags
are repeatable unlimited times within a record?

InteractivityType--Would you be able to provide more examples of what
would be put in this tag?

Thanks
Pat

I can see that use case, but, with the goal of simplicity in the LRMI
(because of the goal of simplicity[1] in Schema.org) I don't see the
distinction being added explicitly in LRMI.

This could be a good place for a strong community of practice to emerge.

There is always the choice of searching across LRMI tagged material for
"ESL" (or similar) material and limiting it to, eg,
"typicalAgeRange=12-16" and getting the results many would expect.

Assumed unlimited repeatability. However, some items don't make semantic
sense to repeat, eg, dateCreated.

This term addresses the same concept (hence the same name) as
Interactivity Type in IEEE LOM. Thus, the three values that we suggest
publishers to use are:
* active - active participation from the learner, eg: exercises
* expositive - passive participation, eg: lecture
* mixed - a mixture of the two.

Hope that helps!

There is surly value in this kind of "High interest" or "Developmental"
usage distinction. This, impart, is why it is labeled "TypicalAge". It is
really the competency alignment that would identify the specific "skill
level" as apposed target user "Age range." You certainly could have a 3rd
grade skill competency alignment and an adult typicalAgeRange. Does this
meet your use case?

Re: isBasedOnURL - This is repeatable, yes.

Re examples (or perhaps other terms) for InteractivityType -> I will differ
to others here, but I tend to agree that this could be much more clearly
defined and have more discrete and useful values. I would prefer to see
something that is more meaningful in terms of curriculum
integration/selection and functional interoperability.

That is a good point, Joshua, that I completely forgot while replying to
Pat initially. The combination of a typicalAge + Competency might give
you exactly what you want, if there is an agreed upon competency that
says what you want (eg: "This material requires a 6th grade English reading
level").

Best,

Greg

For coding materials to age range and other attributes like
accessibility I recommend looking at the IMS Access for All
Specification.
