Hi there! I would like to use icons from font awesome in addition to the ontology icons. Is this possible? (https://fontawesome.com/)
In most cases, no.
If you would like to set the icon for individual objects (not object types) you can use one of the following typeclasses (hubble:media_url, hubble:icon or hubble:thumbnail) on an object property that contains a link to the icon or image you would like to use as a thumbnail. You can then point to fontawesome icons hosted externally or within foundry.
(for example, https://www.palantir.com/docs/foundry/workshop/widgets-object-table/#configuration-options)
Hope this helps
