Rework data structures using Schema.org Blueprints

Problem/Motivation

The schema.org data structures are a large set of data structures which search engines can use to provide "rich" previews of content.

In order to add schema.org integration on the website we have to add the necessary fields using Schema.org Metatag and map the fields in place. It's likely the current data structures were not built with standardized data structures in place, so adding these will take a bit of work to map it all together.

Proposed resolution

Use Schema.org Blueprints to build the data structures in Rain.

Remaining tasks

Rework the data types.
Update the integration.

User interface changes

None for content admins.
TBD for others.

API changes

TBD.

Data model changes

TBD.
