[dini-ag-kim-oer] Fwd: Simplifying LRMI in schema.org

[Adrian Pohl]

Liebe Leute,

das wird einige hier interessieren. LRMI wird verbessert, indem einfache 
Properties (teaches, assesses, educationalLevel) ergänzt werden, um eine 
Lernressource mit einem Lehrplan o.ä. zu verküpfen.

Viele Grüße
Adrian Pohl

Hello all

On behalf of the DCMI-LRMI task group 
<https://www.dublincore.org/groups/lrmi-task-group/> I would like to let 
you know about some developments relating to LRMI (Learning Resource 
Metadata Initiative) properties in schema.org.

As you know it is possible to use the educationalAlignment 
<https://schema.org/educationalAlignment> property and an 
AlignmentObject <https://schema.org/AlignmentObject> to show how a 
learning resource relates to shared educational frameworks as an 
indirect way of expressing information about important educational 
characteristics (the AlignmentObect's alignmentType 
<https://schema.org/alignmentType>). All the feedback that we have to 
date indicates that this is overly complex and under used.

We have been considering this problem and over the last few months have 
developed a suggestion to address it by adding simple properties for 
some of the most common / most important relationships. This proposal 
will add the properties teaches andassesses to reference the 
competencies the resource is intended to help someone learn or assesses, 
and educationalLevel to reference the level of the resource in terms of 
progression through through an educational or training context. These 
properties are suggested for addition to CreativeWorks and 
EducationEvents. We acknowledge that there may be other properties that 
can be expressed directly, for example relating to prerequisites.  The 
educationalAlignment property and AlignmentObject will be retained to 
catch the long tail of other types of alignment, but its use where there 
are direct properties should be discouraged in the future.

Today I submitted this proposal to schema.org as an issue 
<https://github.com/schemaorg/schemaorg/issues/2427> and pull request 
<https://github.com/schemaorg/schemaorg/pull/2428> that makes the 
necessary changes to schema.org. Perhaps the easiest way to view these 
is on our test-instance of the schema.org website: see

   * teaches <http://lrmi-sdo.appspot.com/teaches>
   * assesses <http://lrmi-sdo.appspot.com/assesses>
   * educationalLevel <http://lrmi-sdo.appspot.com/educationalLevel#>
   * EducationEvent <http://lrmi-sdo.appspot.com/EducationEvent>
   * AlignmentObject <https://lrmi-sdo.appspot.com/AlignmentObject>

You can comment on these suggestions either here or on the issue 
<https://github.com/schemaorg/schemaorg/issues/2427> I raised on github.

When pending any suggestions arising from the proposal to schema.org, 
these properties will proposed as additions to the DCMI LRMI Terms
