Survey of *consuming* apps that make use of Schema.org's medical/health vocabulary

Hi folks

I am investigating the deployment status of the schema.org medical
vocabulary. This is a call to see who is making any use of the vocabulary
in significant use-facing applications.

The medical/health vocabulary was added back in 2012, and then cleaned up
somewhat by folks here. In all that time I have not become aware of any
significant application that consumes (i.e. uses) schema.org data based on
this vocabulary.

(fwiw, at Google, we have not found the vast majority of the detailed
medical terms to be useful for Search.)

To be clear, this does not reflect poorly upon the work that was done here
to fix some of the problems with the original design. I think it is rather
that Schema.org made a mistake by adding such a massive set of vocabulary
terms without motivating use-cases. Much of the vocabulary (see
https://health-lifesci.schema.org/) is poorly suited for use in the public
Web, both in terms of levels of detail and also because many of the terms
look more applicable to private data residing patient record systems
where other more widely used data standards already exist.

I suggest we partition the medical/health vocabulary into a smaller set of
terms that are aligned with Schema.org's strengths (e.g. simple public
information in the Web), and that most of the rest that are not being used
should be moved to the "Attic" area of schema.org.

Schema.org also periodically encounters problems with the names chosen for
the medical types and properties. My colleague, Tiffany Jann (cc:'d) has
prepared an initial list of terms (
https://github.com/schemaorg/schemaorg/issues/2435) that have been used for
medical concepts in a way that is problematic for schema.org's wider
usability. Again, if there are significant medical/health uses of these
terms, please let us know in this thread.

Thanks for any information,

cheers,

Dan
