Metadata reference [VC 21.3 GEN]

This page describes metadata related resources for item and collection.

In the following reference, {metadata-entity} is one of the following:

  • /item

  • /collection

Get metadata for an entity

Retrieve metadata

GET {metadata-entity}/(entity-id)/metadata

Returns the metadata set for an entity. This means all metadata change sets, combined, and then filtered according to query parameters.

Conflicts are normally returned with all possible values. With conflict=no, a user interface may choose to receive only one value; i.e., automatic conflict resolution will be enforced. The conflict resolution is only applied to the returned XML document, not to metadata in database.

Query Parameters:

  • projection (string) –

    (only supported in item metadata)

    Return metadata set according to projection. Default is default.

  • interval (string) –

    Comma-separated list

    • time-span - Filter out metadata, return only metadata for specified time span.

    • generic - Return all non-timed metadata.

    • all (default) - Return all metadata, same as interval=generic,-INF-+INF

    • result - Can be used when retrieving metadata from a search result. Will return time spans that overlap with the search result. (New in 5.5.)

  • starttc (boolean) –

    • true - Interval is given relative to start timecode of item.

    • false (default) - Interval is 0-based.

  • field (string) –

    Comma-separated list.

    • field-name - Return specified field.

    • field-name “:” new-name - Return specified field, renamed to a new name in return value.

Manipulating change sets

Create a metadata change set

PUT {metadata-entity}/(entity-id)/metadata

Sets the metadata for an entity, or, more specifically, creates a metadata change set for an entity.

The metadata change set binds to different intervals, tracks, and languages, which can be specified either in the URL or in the XML. Providing an empty timespan or an empty field will be interpreted as the removal of any existing element that matches. Fields specified by the system will not be removed by this action.

The revision can either be specified in the input XML/JSON or as a query parameter. If it is not set at all, it will attempt to override any existing values.

Query Parameters:

  • revision (string) – The known revision. If not specified, the change set will attempt to override existing change sets.

  • skipForbidden (boolean) – Skip fields or groups that the user doesn’t have write access to. Default is false

  • projection (string) –

    (only supported in item metadata)

    Sets metadata set according to projection. Default is default

  • output-projection (string) –

    (only supported in item metadata)

    Returns metadata according to projection. Default is default

  • onlyReturnChanges (boolean) –

    New in version 4.16.6.

    • true - Only return the changed entries.

    • false (default) - Return the whole global metadata after the update.

Status Codes:

  • 400 – Invalid input.

  • 404 – Invalid id.

Accepts:

  • application/json, application/xml – MetadataDocument or according to specified projection

Move metadata

PUT {metadata-entity}/(entity-id)/metadata/move

Moves the specified field or group from one timespan to another. There are some restrictions to this operation:

  1. Only top-level elements can be moved, i. e. no groups or fields that belongs to a group can be moved.

  2. All conflicts for the specified element must first be resolved before moving it.

  3. If moving a field, it cannot be set as sortable.

  4. If moving a field, it cannot be system specified.

Query Parameters:

  • start (string) – The new start time code

  • end (string) – The new end time code

  • uuid (string) – Required. The UUID of the element.

Status Codes:

  • 400 – Invalid input.

  • 404 – Invalid id.

Retrieve a change set

GET {metadata-entity}/(entity-id)/metadata/changes/(changeset-id)

Retrieves a specific change set.

Status Codes:

  • 404 – Could not find the entity or the change set.

Compare two change sets

GET {metadata-entity}/(entity-id)/metadata/changes/(changeset-id)/compareTo/(from-changeset-id)

Retrieves a metadata document containing the differences between the entity metadata as of revision changeset-id compared to the metadata as of revision from-changeset-id.

The mode attribute is used to indicate if a field, field group or value has been added or removed.

Note: This should be seen as a diff between the metadata as it was between the two revisions, meaning that for example fields or field groups that have been added and then removed in between will not be shown.

Parameters:

  • from-changeset-id (string) – The id of the change set to compare against. Use previous to compare with the preceding change set.

Query Parameters:

Status Codes:

  • 404 – Could not find the item.

And we want to change the title of this item’s metadata. Note that the UUID of the title value is 17d6bac2-56c4-4117-b0dd-da474912bc3c. We can then make the following request;

NONE 
PUT /item/VX-10/metadata/entry/17d6bac2-56c4-4117-b0dd-da474912bc3c
Content-Type: application/xml

<MetadataEntryDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <value>my item's new title</value>
</MetadataEntryDocument>

If we instead want to replace the values in the item_tags field, we can make the following request:

NONE 
PUT /item/VX-10/metadata/entry/e2e964d4-5376-47f0-83dd-f4e3663181d8
Content-Type: application/xml

<MetadataEntryDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <field>
    <name>item_tags</name>
    <value>new tag 1</value>
    <value>new tag 2</value>
  </field>
</MetadataEntryDocument>

This works in a similar fashion for field groups too.

Example

The above changes could be made in one request in the following way:

NONE 
PUT /item/VX-10/metadata/entry
Content-Type: application/xml

<MetadataEntryListDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <entry uuid="17d6bac2-56c4-4117-b0dd-da474912bc3c">
    <value>my item's new title</value>
  </entry>
  <entry uuid="e2e964d4-5376-47f0-83dd-f4e3663181d8">
    <field>
      <name>item_tags</name>
      <value>new tag 1</value>
      <value>new tag 2</value>
    </field>
  </entry>
</MetadataEntryListDocument>
