Nuxeo Platform User Documentation

Digital Asset Management with the Nuxeo Platform

Updated: December 6, 2021

The Nuxeo DAM document types are fully integrated in the Nuxeo Platform and are available alongside the other document types. They can be created the same ways as the platform default document types, they get the same metadata, the same workflows, etc.


Pictures are specific files. To take into account the specificities of pictures, their Summary tab shows additional pieces of information, such as:

  • Rotate actions
  • The picture's EXIF metadata
  • Additional picture views

Pictures can be created and edited in workspaces and folders like any other document type. You can also classify and organize them in collections.

When pictures are created, the EXIF metadata of the pictures are automatically extracted and displayed on the Summary tab. They cannot be modified. The IPTC legend, copyright and source are used to automatically fill in the description, rights and source metadata. See the page Binary Metadata for more information.

You can report to the page Supported File Formats to see which file formats are supported as pictures.

Browsing Pictures

Nuxeo DAM add the possibility to view pictures in a slideshow mode from the thumbnail mode of a workspace or search results. To view the pictures in a slideshow mode, click on the icon from the thumbnail mode. You can then switch from one picture to the next or the previous using the right and left keys of you keyboard. You automatically go the next page picture when you're at the last picture of the current page.

If no picture is available on the current page, it shows the icon .

Annotating Pictures

Annotations are post-it notes that users can add on the picture to comment it or to comment a specific part of the picture.

To add an annotation on a picture:

  1. To access to the image view, click on the icon  in the More menu. A pop up opens.
  2. Draw a frame on the part of the picture you want to annotate.
  3. Type your annotation and click on Submit.
    You can see your annotation when the mouse is over the zone you selected, and, in the margin, the list of annotations, and for each, the author, date and time of annotation and the text.

Picture Views

When you import a document having the Picture facet on your platform, additional formats are available on it. The default ones are:

  • Thumbnail: the picture is converted to JPG and resized to 100 px height or width.
  • Small: the picture is converted to JPG and resized to 280 px height or width.
  • Medium: the picture is converted to JPG and resized to 550 px height or width.
  • OriginalJpeg: the picture is converted to JPG but the original size is kept. This export is done even if the original picture was a JPG file.

The original and medium pictures can be the same size when you download them if the original is smaller or equal to medium size.

To download the picture view that you want, click on  in front of it.

To contribute new picture views, follow this how-to.

A user interface is added in the Admin tab so that it is possible to re-compute picture conversions (Picture views). This is particularly useful when you add new conversions and want to compute them over existing images, or if you change the definition of some of the existing conversions.
