# Types:
#     - Nativ datatypes: string, number, boolean, JSON
#     - HTML: A 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.
#     - <T>[]: This indicates and arbitrary array of the given type.
# Relations:
#     - We have the following types: `relation`, `relation-list`, `generic-relation`
#       and `generic-relation-list`.
#     - Non-generic relations: The simple syntax for such a field
#       `to: <collection>/<field>`. This is a reference to a collection. The reverse
#       relation field in this collection is <field>. E. g. in a motion the field
#       `category_id` links to one category where the field `motion_ids` contains the
#       motion id. The simple notation for the field is `motion_category/motion_ids`.
#       The reverse field has type `relation-list` and is related back to
#       `motion/category_id`. The type indicates that there are many
#       motion ids.
#     - Generic relations: The difference to non-generic relations is that you have a
#       list of possible collections. Therefor we split the simple notation up to the
#       properties `collection` and `field`.
# Structured fields:
#     - There are template fields (see autoupdate service interface) with a `$` as
#       the placeholder. We have three different types: `template`,
#       `structured-relation` and `structured-tag`.
#     - The type `template` describes a structured field for the given model. The
#       property `replacement` describes the meaning of the template. The property
#       `fields` contains the definition for all the fields that come from the template
#       field.
#     - The type `structured-relation` describes the content of a related field as a
#       structured field (with properties `name`, `replacement` and `through`).
#     - The type `structured-tag` describes the content of a related field as a
#       structured field where the template is filled with arbitrary strings instead of
#       instance ids.
