Schemas

We use JSON Schema ( draft v4 ) as a core feature for data description.

Here you can find docs and examples.

Changed behaviour

We had to change some property behaviours to fit our goals:

We also added some new attributes:

Attribute	Description
processors	add a list of processors to the field
required	marks a field as required. By default the field is not required. See the example below.
immutable	marks a field as an immutable. This means - you cannot change a field after it was created.
position	decorative helper attribute to assign a position in UI

Default data types:

Name	Description
array	array
boolean	boolean
integer	number without a fraction or exponent part
number	number
null	null value
object	object
string	string

We added some custom types to extend default schema:

Name	Type	Description
file	object	accepts a file uploaded using `multipart/form-data`
datetime	string	format ISO 8601
embed	object	makes possible to set a data source

These two are valid datetimes:

All datetime without a timezone will be assumed to be a UTC.

You can set a date to 2015-06-03T18:55:59.073+03:00 this will be converted to UTC and properly saved to database.

Property	Type	Required	Description
collection	string	*	points to collection for data to fetch from
field	string		the field of a collection. default is `_id`
