Support for @Id

[KajKandler]

In Schema markup, there is an important attribute (if not the most important one), to support @id for entities.

In webpages, mostly the @id attribute is set to the URL (i.e. "https://example.com/about-us/") or URL derived from the web page's URL, such as "https://example.com/#organization"

I tried to set value in the front matter to {url}, which did not work. Is there a way that is not obvious? If so it would be great to document it.

P.S.: @id is a very important attribute, so one can assemble schema from different pieces and amend schema defined in the header also in the body (affording the power of templating)

Interesting! I didn't know about that feature, so I've been reading more here: https://schema.org/docs/datamodel.html#identifierBg

I'll add this to the next release

An implementation note:

• the URIs used as IDs are supposed to be http:// not https://
• technically it is possible to use https, but the norm is http
• that implies if one can utilize the url or base url as part of the value it should allow exchange of the scheme

See url_for in Flask framework for how this is supported there.
