Best Practices for SEO JSON-LD, RDFa, Microdata in OrchardCore?

[bashuss]

I am just wondering which way to go, to enhance at least some of my pages with structured data.

I am not at all drawn to JSON-LD, though it may be the easiest thing.

I thought about using shortcodes for declaring structured data properties and items inside html texts. BTW: can shortcodes be nested?

For some content I have the problem though, that I would need to declare the structured data item on a level that needs to be accessed by the templates. So changing contentTypes to pass the data and changing templates to use that data should not be done without proper thoughts.

Any experience out there, that you would like to share?
Any features for OC, we may get from this discussion?
