catalist network
an early-stage platform for building a collaborative database of social impact / systems change / regenerative projects - https://www.catalist.network/
the project proposes an interesting ontology: spaces, objects (with types), sets and attributes. see: https://www.catalist.network/explore
they have also launched a project in partnership with the buckminster fuller institute building on top of that ontology, called omnimapping project, which is can be very relevant for futures literacy and systems mapping as a whole.
