Information for specific systems

MediaCentral Asset Management

In case of multi-value attributes, the rows given in the request fully replace the currently existing rows. You can’t modify, delete or insert individual rows with this link rel.

In MC|AM, it is not possible to update a multi-value attribute to contain only a single, empty row with this link rel. MC|AM interprets that as a command to delete all existing rows of that attribute. To create a single, empty row, use aa:multi-value-attribute-by-attributeid or aa:multi-value-attribute-range-by-attributeid, followed by aa:update-multi-value-attribute with a request body like this:

[
  { "op": "remove", "path": "/rows" },
  { "op": "add", "path": "/rows/-"}
]

MediaCentral Production Management

The body is expected in the same format that is returned when getting the information about an aa:attributes resource. Only modifiable (i.e. those not having the system model’s readOnly flag) custom attributes that are given in the payload are updated. - All custom attributes specified in the request must be modifiable for the request to succeed. Passing timecode in SMPTE notation, it’ll just be written as string. Passing timecode as integral value, it is assumed to represent a frame count. In this case, the property "editRate" must be specified as well, i.e. the payload must have the property "editRate" with a valid value. Also the property "dropFrame" is considered, when dealing with a frame count. If "dropFrame" is not specified, it defaults to false.

Note:: Updating an asset may not update the common attributes – modifier, modified or the attribute Changed By

MediaCentral Newsroom Management:

Client needs to lock asset form to be able to update attributes. The URI has additional query parameter lockId - asset lock id. After update the lock is automatically removed. See Link Relation - ia:lock-asset-by-id for details.
