schema.org/SpecialAnnouncement: Add structured data to COVID-19 announcements, schema.org/CDCPMDRecord: US CDC hospital data reporting

[Wes Turner]

I normally wouldn't post non rdflb-project-specific messages to this list, but I thought I'd share these useful applications of [schema.org RDFS schema] structured data (which can be parsed with rdflib-jsonld and into rdflib from RDFa or Microdata) for COVID-19 pandemic response efforts:

"Add structured data to COVID-19 announcements (BETA)"
