Selecting a semantic element will display its properties in the Details View (if it is opened). If the selected element is represented on a diagram that is currently opened, the graphical element (node or edge) where it appears on the diagram will also be selected, and the view will center on the selected element.

Selecting a representation will open it in a new tab (or focus on an existing tab where it was already open).

the image Label (which is only for information purposes);

the server-relative URL where the image can be obtained, will be of the form /custom/<unique-id>. Two icons are visible at the right of the URL: the first copies the URL into the clipboard, the second can be used to preview the image.

a Delete button which can be used to remove the image (after a confirmation). Deleting an image completely removes it from the server, and may break existing representations which use it.

in a Form using the Image widget type. In the image’s URL Expression, enter the server-relative image URL which will be of the form /custom/<unique-id>.

Open the Project Edition page for the project which contains the document.

In the Project Explorer, select the top-level element which represents the document to export, and open its menu by clicking on the button (three dots) at the right.

Click on the Download button, an XML file named after your document is saved on your disk.

Click the Upload Project card at the top.

Click on the Click here to select a file area.

Select a compatible archive with the file selector.

Click on the Upload project button.

Go to the Project Editor.

Open the context menu of the project in the header.

Select the Upload model action.

Click on Click here to select a file

Choose a model from your local disk.

Click on the Upload button, a new model will be displayed as a root element, in the project explorer.

Whenever you change something in the definition of a domain, you must close any project which contain instances of that domain, and wait a few seconds before re-opening it. Just reloading the browser’s page will not be enough for the instance project to pick up the new definition of your domain.

The model where you define your domain should contain nothing else, and in particular no instance of other dynamic domains.

There is currently no automatic migration of the data in domain instances. If you have created instances of a v1 of some domain, and then change the domain definition into a new version v2 which for example renames some elements, the data stored as instances of v1 may be partially or totally lost when re-opening the project and loading the model as an instance of v2.
