What are the differences between using name and property in metatags

Issue

• We were creating custom meta tags and we see there are created using "property" attribute instead of "name" attribute. Are there any differences between using name and property? Are they equivalent?
• Could we modify current implementation in order to use "name" instead of "property"?

Environment

• Liferay DXP 7.4

Resolution

• The name attribute is the "usual" way for specifying metadata in HTML. It’s defined in the HTML5 spec.

• The property attribute comes from RDFa.

• RDFa 1.1 extends HTML5 so that it’s valid to use meta and link elements in the body, as long as they contain a property attribute.

• You can use both ways, HTML5’s name and RDFa’s property, together on the same meta element.

• In order to replace current implementation and use name instead of property, you have to create a custom DynamicInclude that replaces OpenGraphTopHeadDynamicInclude and blacklist the original component. Bear in mind that any change that Liferay perform over that component should be adapted to your custom component.
