By default, Dash comes with some embedded metadata mappings preconfigured:
Caption -> populates the Title attribute
Description -> populates the Description attribute
Keywords -> populates the Tags attribute
Date Time Original -> populates the Date Created attribute.
When a file is added to Dash, either through an upload or import, Dash will extract the metadata stored within the file and use it to pre-populate the new asset's attribute values according to the mappings above.
Some files (e.g. photos) include additional embedded metadata (often EXIF tags) that are not mapped by default in Dash. This could include, for example, the camera and exposure settings.
If you would like the data in these fields to automatically populate your attributes in Dash, you can create a custom attribute that is automatically populated with a specific embedded field of your choosing. (Note that this will not populate existing assets already imported).
Let's say we want to create an attribute to show the ISO (exposure) information of a photo:
Create a new text attribute called "ISO"
Now edit the ISO Attribute and expand the section called "Populate with data embedded in the file".
In the text field shown, enter the EXIF metadata tag that you want to populate this Attribute with. In this case, the ISO tag is simply called "ISO", so enter that here.
For assets uploaded from this point on, the ISO information will be populated into the ISO Attribute
What tags do we support?
We support all tags that are found embedded in the assets imported into Dash, even if they are not standard tags. You just need to know the name of the tag, which you can do by querying the asset using an EXIF viewer tool or by clicking the 'View embedded file data' on the Asset Details page in Dash (found under the dropdown to the right of the 'Original file' in the metadata panel).
