Image annotation

The image annotation feature allows for marking areas on an image and adding a text and/or link to an entity. In that way a person in a group picture or an artifact on an excavation photo can be linked to the entity in OpenAtlas.

Prerequisite for image annotation is an enabled and configured IIIF server.

Usage

In a File’s detail view, click the Enable IIIF view button below the image, if it is not converted already. Once the image is converted click the Annotate link below the image and the annotation view will open in a new tab.

In the image annotation view you can see the image in an IIIF viewer as well as a form for new annotations including a list of already saved annotations. Links to edit or delete previous annotations are als porvided.

Form fields

• IIIF image view - click the button on the left to draw a rectangle to mark the desired area.

• Annotation - enter a description

• Entity - link to an entity

Be aware that the Entity selection only offers entities that are already linked to the file. This guarantees that each selectable entity is also linked to the file via the model. Immage annotation does not create new model links in the background!
