Fixes for HTML/RDFa/Microdata in OpeningHoursSpecification example
same data like HTML for JSON-LD OpeningHoursSpecification example
See #533 #143 #1012.
@unor - I merged this into sdo-ganymede rather than sdo-deimos without thinking. Fixing manually with a new pull request to sdo-deimos that has conflicts. Possibly these have been fixed already at least in part.
