An asset is the combination of a file and information about this file (metadata). Certain quick information is available without having to leave the home screen. Clicking an asset gives access to viewing and editing all the available metadata (if the correct role is assigned to the user).

Types of metadata fields

According to the criterion of editability, there are three types of metadata fields:

Type	Description	Illustration

Type	Description	Illustration
Required	The user has to edit the field. The changes cannot be saved until there is a valid value in the metafield.	Open
Editable	The user can edit the metafield.	Open
Read-only	The user can only view the metafield and cannot edit it.

According to the criterion of data type, the user can encounter among others:

Quick asset info

The "i" button located on the asset card or ‘Asset info’ button in the ‘More’ menu (dependent on the asset card configuration) gives quick access to selected asset’s information. Once the user clicks the button, the information is displayed in a small dialog. The dialog can be closed again either by clicking the same button again or by clicking empty space anywhere in Media Manager.

Metadata edit on a single asset

When the user clicks on asset, they gain access to the asset detail view. On the left side on the screen, all the available metadata is located under ‘Metadata’ tab. Metadata is divided into metadata groups that can be expanded and collapsed individually by clicking on the header of the metadata tab. An administrator can configure which tabs are expanded or collapsed by default in Administration → Portals → Configuration. Each metadata group contains a number of metadata fields. 

In order to edit a single metadata field, the user needs to click/tap on the pencil symbol next to it or anywhere within the header area of the metadata field.

It is also possible to activate/de-activate the edit mode on all metadata fields within a metadata tab at once by selecting ‘Edit’/'Edit (off)' on the metadata tab header.

Saving changes in metadata

Once the changes to the metadata have been made, the user can either keep them them by clicking ‘Save’ or discard them by clicking ‘Discard’.

If the user makes changes to the metadata and attempts to leave the asset preview without saving, the following prompt will appear:

Once the user clicks the ‘Save’ button, a small notification appears in the lower right corner, informing the user that the changes are being saved in the background and the user can leave the metadata editor. This is relevant especially in case of saving many changes on multiple assets at once, as this process can take longer time.

Pinned metadata

It is possible to pin favorite metadata fields to the top of the metadata editor.

When the user hovers the mouse pointer over the name of a metadata field, a greyed out 'Pin' symbol appears next to it with the explanation 'Pin to top'.

Clicking the pin will result in the metadata field being duplicated in a metadata group 'Pinned metadata' located at the top of the page. The group is only visible, if there exists at least 1 pinned metadata field.

In order to remove the field from the pinned metadata, the user needs to hover again over the name of the metadata field and click on the colored pin. The field will be unpinned.

Input validation

In some cases the system validates whether the correct format of input has been used. If the input value has incorrect format and the user tries to save the changes, the "Save" button will turn red and the message "Error while saving metadata" will appear at the botton of the page. The following input types can be validated:

• e-mail,

• timecode,

• URL,

• color.

Dependency

Some of the metadata fields are only shown conditionally. Dependency can be configured in the DAM Center. There are two types of metadata field dependencies:

1. Dependency on another metadata field
   The metadata field will appear only, if a certain value is selected in another metadata field.

2. Dependency on asset type
   The metadata field will appear only under a specific asset type, e.g. field called ‘Duration’ under videos.

Language versions

Metadata fields can have different language versions. If more languages are set up in the DAM Center, the user will see an arrow symbol next to a metadata field. Clicking it will open input fields for all the available languages:

AI Services

Digizuite™ Media Manager integrates with a number of Cognitive Services.

Cognitive Service available for image files are: AI tagging, AI detection of offensive content, AI detection of landmarks, AI generation of description as well as AI facial recognition:

Open

Cognitive Service available for video files is AI generation of transcript:

Open

AI Tagging

The metadata field for keywords contains a button "Generate AI keywords". Clicking the button results in the appearance of a series of suggested keywords generated by the AI Service. The user can choose to either keep all of them, remove some of them or discard all of the suggested keywords.

The user can generate AI keywords both for a single asset and for multiple assets at the same time.

AI detection of explicit content

A new metadata field is created for this Cognitive Service and it can be named according to the administrator's wishes. Clicking the field reveals a button "Check for explicit content". Once the check is finished, the user received a notification in the lower right corner and the correct values and inserted in the field automatically.

AI landmark detection

A new metadata field is created for this Cognitive Service and it can be named according to the administrator's wishes. Clicking the field reveals a button "Detect landmarks". Once the process is finished, the user receives a notification in the lower right corner and the names of the detected well-known places are inserted in the field automatically.

AI description generation

A new metadata field is created for this Cognitive Service and it can be named according to the administrator's wishes. Clicking the field reveals a button "Generate AI description". Once the description is generated, the user receives a notification in the lower right corner and the suggested description of the activity in the image is inserted in the field automatically.

AI facial recognition

A new metadata field is created for this Cognitive Service and it can be named according to the administrator's wishes. Clicking the field reveals a button "Detect faces". Once the process is finished, the user receives a notification in the lower right corner and the names of the detected well-known people are inserted in the field automatically.

This Cognitive Service needs to be trained before it can begin functioning properly.

AI video transcript

A new metadata field is created for this Cognitive Service and it can be named according to the administrator's wishes. The user needs to click the button "Generate transcript" in order to initiate the process. This can take several minutes. Once the transcript is ready, a standard notification will appear at the top bar. Clicking the notification take the user directly to the transcript metafield. 

The user can now click "View transcript" which will open the text together with the timestamps in a pop-up window. The user can now edit the suggested text and save the changes once finished.

If a transcript already exists, the lower button will change into "Re-generate transcript". This will overwrite the previous transcript.

Audit trail

Open

Audit Trail (located in the actions menu under the asset preview) is the history of metadata changes performed by the users or by the system. It contains the following information:

• time of the change,

• author of the change,

• metafield that has been changed,

• new value in the metafield.

More information can be found here.
