Just my two cents: What may work as a starting point is to use a more abstract type from schema.org, like


and then indicate the more special meaning using additionalType and www.productontology.org, e.g.



I admit that both are no perfect fit for the use-case under discussion, but they may be good enough to get started with using respective markup in live sites.

Full example:

(Note: There is no contradiction in the fact that www.productontology.org types are specializations of ProductOrService from GoodRelations, since anything on which any kind of rights can be obtained are instances of that type.)

<!DOCTYPE html>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
    <title>A presentation slide</title>
<div itemscope itemtype="http://schema.org/CreativeWork" itemid="#slide01">
    <link itemprop="additionalType" href="http://www.productontology.org/id/Presentation_slide" />
    <span itemprop="name">.. a short name for the slide ...</span>
    Slide description: 
    <span itemprop="description">... a longer description ...</span>

... other schema.org properties go here ...

The idea of www.productontology.org is two-fold: First, it aims at covering the specificity of the long-tail of types in knowledge representation. Second, it is meant as an incubator for collecting interest in often needed yet missing types in Web vocabularies. I.e., the natural action of the schema.org maintainers (or the maintainers of any other Web vocabulary) to a very popular type from the www.productontology.org namespace would be to add a respective type to the official "mainstream" vocabulary.
