# Types:
#     - nativ datatypes: string, number, boolean, JSON
#     - HTML: string with HTML content
#     - float: numbers that are expected to be non-integer. Formatted as in rfc7159.
#     - decimal(X): Decimal values represented as a string with X decimal places
#     - datetime: Datetime as a unix timestamp. Why a number? This enables queries
#       in the DB. And we do not need more precision than 1 second.
# Relations:
#     - <collection>/<field>: This is a reference to a collection. The reverse relation
#       field is <field>. E.g. `category_id: motion_category/motion_ids` in a motion links
#       to one category. The reverse field is `motion_ids` which may be `motion_ids:
#       (motion/category_id)[]` indicating, that there are many motion ids.
#     - <T>[]: This indicated multiple ids. For an example see above.
#     - {x,y,z}/<field>: This is a generic relation (analog: `({x,y,z}/<field>)[]` a
#       generic list relation) with fqids as values to the given ollections x, y and z.
#     - If no field is specified, there is no reverse relation.
# Structured Fields:
#     - There are template fields (see autoupdate service interface) with a `$` as
#       the placeholder. In this document, angle brackets are followed by the
#       dollar sign including the meaning of the template. E.g.
#       group_$<meeting_id>_ids: (group/user_ids)[];
#       says, that the template are meeting ids and each structured field is a
#       multi-relation to groups and the reverse relation field for groups is
#       user_ids.
