Metadata API reference

Overview

Cloudinary structured metadata allows you to define typed fields for media assets, populate them with values programmatically or via the Media Library, and perform searches on them. You can also add validation rules, set default values, and define fields as mandatory.

A metadata field is a custom, typed field (key) for storing user defined data (value) with a media asset.

Note

Cloudinary account clouds are limited to a maximum of 100 structured metadata fields each. After reaching the maximum, you must disable one or more existing fields in order to add a new one.

This page explains the Metadata methods for creating and managing structured metadata fields, as well as the Metadata field structure and how to structure field validation and list (datasource) values.

Tip

It's also possible to create and manage structured metadata fields in the Manage Structured Metadata page of the Cloudinary console. For details, see Structured metadata management in the Digital Asset Management Guide.

Quick example

Add a new mandatory metadata set (multi-select) field with an external_id of 'color_id', labeled 'Colors', and with 4 available colors: red, green, blue and yellow, where red and green are the default values:

Ruby:

Cloudinary::Api.add_metadata_field({

  :"default_value" => ["color1","color2"],
  :"datasource" => {
    :"values" => [
      {:"external_id" => "color1", :"value" => "red"},

Delete entries in a metadata field datasource

Deletes (blocks) the datasource entries for a specified metadata field definition. Sets the state of the entries to inactive. This is a soft delete, the entries still exist under the hood and can be activated again with the restore datasource entries method.

Metadata field structure

{
    "external_id": <string>,
    "type": <field_type_enum>,
    "label": <string>,
    "mandatory": <boolean>,
    "default_value": <field_type_value>,
    "validation": <validation_object>,
    "datasource": <datasource_object>  //enum and set types
}

Parameter	Required	Description
`external_id`	No	A unique immutable identification string for the metadata field. Default: auto-generated by Cloudinary (although it's recommended to specify a descriptive name). Max character length: 255.
`type`	Yes	The type of value that can be assigned to the metadata field, possible types are limited to: * `string` - a single string value * `integer` - a single integer value * `date` - a custom date in the following format: {yyyy-mm-dd} * `enum` - a single value referenced by an `external_id` from a given list, predefined with the `datasource` parameter * `set` - multiple values referenced by `external_id`s from a given list, predefined with the `datasource` parameter
`label`	Yes	The label of the metadata field for display purposes.
`mandatory`	No	Whether a value must be given for this field, either when an asset is first uploaded, or when it is updated. Default: `false`
`default_value`	Yes (if `mandatory` is true)	The default value for the field (a set can have multiple default values defined by an array). Default: `null`
`validation`	No	Any validation rules to apply when values are entered (or updated) for this field. See Validating data for more details. Default: `null`
`datasource`	Yes (for the enum and set `type`)	The predefined list of values, referenced by `external_id`s, available for this field. See Datasource values for more details.

Validating data

The validation parameter defines a validation object with the logic to apply when a value is entered for the field, via the metadata, upload, explicit or update resource methods, or via the Media Library. The boolean validations also allow for combinations of more than one rule. The following validations are supported:

greater_than
less_than
strlen
and

greater_than validation

Relevant for integer and date types:

{
    "type": "greater_than",
    "value": <value_by_type>,
    "equals": <boolean>
}

Property	Type	Description
`value`	String	The value for validation.
`equals`	Boolean	Whether to check if greater than or equals. Default: `false`

For example:

"validation":{ 
    "type": "greater_than",
    "value": "2018-10-15",
    "equals": true
}

less_than validation

Relevant for integer and date types:

{
    "type": "less_than",
    "value": <value_by_type>,
    "equals": <boolean>
}

Property	Type	Description
`value`	String	The value for validation.
`equals`	Boolean	Whether to check if less than or equals. Default: `false`

For example:

"validation":{ 
    "type": "less_than",
    "value": 50,
    "equals": true
}

strlen validation

Relevant only for string types:

{
    "type": "strlen",
    "min": <positive integer>,
    "max": <positive integer>
}

Property	Type	Description
`min`	Integer	The minimum string length. Default: `0`
`max`	Integer	The maximum string length. Default: `1024`

Note

Either min or max must be given, supplying both is optional.

For example:

"validation":{ 
    "type": "strlen",
    "min": 5,
    "max": 20
}

and validation

Relevant for all field types. Allows you to include more than one validation rule to be evaluated:

{
    "type": "and",
    "rules": [ <validation_object>, <validation_object>, … ]
}

Property	Type	Description
`validation_object`	Object	One of the other validations above: `greater_than`, `less_than` or `strlen`

For example:

"validation":{
    "type":  "and"
    "rules": [{ 
        "type": "greater_than",
        "value": 10,
        "equals": true
    },
    { 
        "type": "less_than",
        "value": 50,
        "equals": true
    }]
}

Datasource values

The datasource parameter is relevant for fields where the selected values must come from a predefined list of values (enum or set type fields). The parameter contains the values property, which defines the values for the enum or set list. Up to 3000 values can be defined for a list.

{
    "values": [ <datasource_entry>, <datasource_entry>, … ]
}

Each datasource_entry defines a single possible value for the field:

{
    "external_id": <string>,
    "value": <string>,
    "state": "active" | "inactive"
}

Property	Type	Description
`external_id`	String	(optional) A unique immutable identification string for the datasource entry, (required if the value is referenced by the default_value field). Default: auto-generated by Cloudinary
`value`	String	(mandatory) The value for this datasource.
`state`	String	(read only) Only given as part of a response - ignored on requests. It is immutable unless changed via DELETE of a datasource entry.

For example:

"datasource": {
    "values": [{
        "external_id": "color1", 
        "value": "red"
    },
    {   
        "external_id": "color2", 
        "value": "green"
    },
    {
        "external_id": "color3", 
        "value": "blue"
    },
    {
        "external_id": "color4", 
        "value": "yellow"
    }]
}
