DOM elements provided by DVM have descriptions compliant with WAI-ARIA.

If you need to create your own elements, for example adding a popup with a thumbnail, you can get the tagging information from the modules API using methods like getMapDescription or getViewDescription.

In the same way if you need to overwrite that with your own information, for example for localization or a more specific description, you can do it with setMapDescription or setViewDescription. The DOM element attributes will be updated with the new provided information.

the input/output of those methods is an object with the following properties:

  • title (string): Currently not used.
  • description (string): Used in aria-label and alt attributes.
  • language (string): Used in lang attributes.
