Resource aa:attributes

Overview

The aa:attributes resource represents the attributes of an asset.

Properties

The aa:attributes resource has the following properties:

editRate	The edit rate of the asset. The value is a string containing a fraction. Example: `{ "editRate": "30000/1001", ... }`
dropFrame	Boolean flag that defines if the asset has a drop-frame framerate. If the property is missing, then the asset doesn’t use a drop-frame format. { "editRate": "30000/1001", "dropFrame": true, ... }
attributes	An array of JSON objects. Each JSON object represents one asset attribute with it’s value. Each JSON object has the following sub properties: name The name of the attribute value The value of the attribute. The format of the value depends on the type. In case of multi-value attributes in MediaCentral Asset Management, the value will be an array. type (Optional) The type of the attribute. If type is missing or empty, the attribute is a string attribute. See below for a list of available types. value-labels (Optional) Display label for the value. This is used for types like list, thesaurus, and masterdata where the value is the ID, but the user should see a more useful text in a UI. The property contains a map of labels with the culture code as key. Example: { "name": "lead_instrument", "type": "thesaurus", "list": "MUSICAL_INSTRUMENTS", "value": "4424ZU43", "value-labels": { "en": "Harp", "de": "Harfe" } } value-tooltips (Optional) Tooltips for the value. The property contains a map of tooltip texts with the culture code as key. Example: { "name": "lead_instrument", "type": "thesaurus", "list": "MUSICAL_INSTRUMENTS", "value": "4424ZU43", "value-tooltips": { "en": "Harp", "de": "Harfe" } } unit (Optional, only for timecode and duration attributes) Returns "frames" if the value is a number of frames, "ms" if the value is a number of milliseconds or "SMPTE", a string showing a SMPTE timecode, if the field could neither be presented as framecount or ms ("SMPTE" can be used, if no editRate was given).

editRate

The edit rate of the asset. The value is a string containing a fraction. Example:

{
  "editRate": "30000/1001",
  ...
}

dropFrame

Boolean flag that defines if the asset has a drop-frame framerate. If the property is missing, then the asset doesn’t use a drop-frame format.

{
  "editRate": "30000/1001",
  "dropFrame": true,
  ...
}

attributes

An array of JSON objects. Each JSON object represents one asset attribute with it’s value. Each JSON object has the following sub properties:

name The name of the attribute
value The value of the attribute. The format of the value depends on the type. In case of multi-value attributes in MediaCentral Asset Management, the value will be an array.
type (Optional) The type of the attribute. If type is missing or empty, the attribute is a string attribute. See below for a list of available types.
value-labels (Optional) Display label for the value. This is used for types like list, thesaurus, and masterdata where the value is the ID, but the user should see a more useful text in a UI. The property contains a map of labels with the culture code as key. Example:

{
  "name": "lead_instrument",
  "type": "thesaurus",
  "list": "MUSICAL_INSTRUMENTS",
  "value": "4424ZU43",
  "value-labels": {
    "en": "Harp",
    "de": "Harfe"
  }
}

value-tooltips (Optional) Tooltips for the value. The property contains a map of tooltip texts with the culture code as key. Example:

{
  "name": "lead_instrument",
  "type": "thesaurus",
  "list": "MUSICAL_INSTRUMENTS",
  "value": "4424ZU43",
  "value-tooltips": {
    "en": "Harp",
    "de": "Harfe"
  }
}

unit (Optional, only for timecode and duration attributes) Returns "frames" if the value is a number of frames, "ms" if the value is a number of milliseconds or "SMPTE", a string showing a SMPTE timecode, if the field could neither be presented as framecount or ms ("SMPTE" can be used, if no editRate was given).

Table of supported types:

string	A string
int	An integer value
float	A floating point value
boolean	A boolean value
date	A date in format YYYY-DD-MM. Example: 2018-04-15
time	A time in 24h format HH:MM:SS. Example: 17:06:29
datetime	A date and time
timecode	A timecode attribute. If the asset has a valid edit rate (meaning: the property editRate is set), then the value is a number of frames. MediaCentral Asset Management: If the edit rate is not valid, timecode represents a number of milliseconds. The property unit tells the client which unit is used. The property value-labels contains a recommended display label for the value. Example: `{ "name": "MY_TC_ATTRIBUTE", "type": "timecode", "value": 93079, "unit": "frames", "value-labels": { "en": "01:02:03.160" } }` New in MC \| Cloud UX 2023.7 Please note that starting with MC \| AM 2023.7 the handling of SMPTE timecode strings around midnight has changed. See timecodes in MC \| AM for details. MediaCentral Production Management: If the edit rate is not valid, value represents the raw value, gotten from the backend, usually, this is a string with a SMPTE timecode. With an invalid edit rate, the property unit will be set to the value SMPTE and the property value-labels will be missing. - The client is then meant to use value to display the attribute’s value, instead of value-labels. When an attribute is updated and a string is passed, it must be a valid SMPTE timecode. When an attribute is updated and an integral value is passed, it is assumed to represent a frame count; in this case a valid edit rate must be specified.
duration	A duration attribute. If the asset has a valid edit rate (meaning: the property editRate is set), then the value is a number of frames. Otherwise it is a number of milliseconds. The property unit tells the client which unit is used. The property value-labels contains a recommended display label for the value. Example: MediaCentral Asset Management: If the edit rate is not valid, duration represents a number of milliseconds. The property unit tells the client which unit is used. The property value-labels contains a recommended display label for the value. `{ "name": "MY_DURATION_ATTRIBUTE", "type": "duration", "value": 93079, "unit": "frames", "value-labels": { "en": "01:02:03.160" } }` New in MC \| Cloud UX 2023.7 Please note that starting with MC \| AM 2023.7 the handling of SMPTE timecode strings around midnight has changed.

When an attribute is updated and an integral value is passed, it is assumed to represent a frame count; in this case a valid edit rate must be specified.
list	A value from a pre-defined list of values. The value of the attribute is a string containing the ID of the list entry. The additional property list defines which value list is used for the attribute. Example: `{ "name": "country", "type": "list", "list": "COUNTRIES", "value": "COJ-2832-323-XYP", "value-labels": { "en": "Germany", "de": "Deutschland" } }`
thesaurus	A value from a pre-defined thesaurus. A thesaurus is a set of values organized as a tree of terms. The value of the attribute is a string containing the ID of the thesaurus entry. The additional property thesaurus defines which thesaurus is used for the attribute. Example: `{ "name": "lead_instrument", "type": "thesaurus", "list": "MUSICAL_INSTRUMENTS", "value": "4424ZU43", "value-labels": { "en": "Harp", "de": "Harfe" } }`
masterdata	A value from a pre-defined list of masterdata records. The value of the attribute is a string containing the ID of the masterdata record.

System-Specific Extensions

MediaCentral Asset Management Multi-Value Attributes

In MediaCentral Asset Management, an attribute can contain multiple values, or even a complete table of values with multiple rows, each containing sub attributes ("multi-value compound attribute"). For those attributes, the values are returned as JSON array.

Multi-Value Non-Compound

A multi-value non-compound attribute contains a list of values. In the aa:attributes resource, the values are returned as a JSON array of values. Each item in the array has an index value, which defines the order of the values and a value property with a value.

The type of the attribute is set to "multi-value", followed by the base type, e.g. "string".

Example: A multi-value non-compound attribute "TEST_MULTI" with three rows

 
{
  "attributes": [
    {
      "name": "TEST_MULTI",
      "type": "multi-value string",
      "value": [
        {
          "index": 0,
          "value": "New York"
        },
        {
          "index": 1,
          "value": "Paris"
        },
        {
          "index": 2,
          "value": "Tokyo"
        }
      ]
    }
  ],
  …
}

Multi-Value Compound

A multi-value compound attribute contains multiple rows. Each row contains a number of sub attributes. It is similar to a table with multiple rows and columns.

The value of a multi-value compound attribute is a JSON array. Each item of the array represents one row. An array item contains:

an index which defines the order of the rows
a property attributes, containing a JSON array with the sub attributes. The format of the sub attributes is the same as for the attributes property of the aa:attributes resource. Sub attributes are always single-value attributes. You can’t have nested multi-value attributes.

The type of the multi-value compound attribute is "multi-value compound".

Example: A multi-value compound attribute "CONTRIBUTORS" with two rows

 
{
  "attributes": [
    {
      "name": "CONTRIBUTIONS",
      "type": "multi-value compound",
      "value": [
        {
          "index": 0,
          "attributes": [
            {
              "name": "ROLE",
              "value": "410"
            },
            {
              "name": "REAL_NAME",
              "value": "Alfred Hitchcock"
            }
          ]
        },
        {
          "index": 1,
          "attributes": [
            {
              "name": "ROLE",
              "value": "488"
            },
            {
              "name": "REAL_NAME",
              "value": "James Steward"
            }
          ]
        }
      ]
    }
  ],
  …
}

MediaCentral | Production Management Attributes

For MediaCentral Production Management the http content-type header must be set to application/hal+json in the aa:update-asset-attributes-by-id request. Attribute types can be "string", "int", "boolean" or "datetime".

Example of a Media Central Production Management attribute:

{
    "attributes": [
        {
          "name": "com.avid.workgroup.Property.User.season",
          "type": "string",
          "value": "season001"
        }
    ]
