Can opening hours schema markup be used with the markup for local businesses or libraries?

Question

Can the OpeningHours mark-up visible in this question for schema.org/Store (example 2) with microdata be used in conjunction with schema.org/LocalBusiness or schema.org/Library?

Answer 1

Schema.org’s OpeningHoursSpecification can be used

• on its own,
• as value of ContactPoint’s hoursAvailable property, or
• as value of Place’s openingHoursSpecification property.

LocalBusiness and Library are more-specific Place types, so yes, you can specify their opening hours by using the openingHoursSpecification property with a OpeningHoursSpecification value.
