"Project spaces" need to be modeled.
From user's perspective, they are customizable areas on a dedicated section of OEB website with descriptive metadata and grouping a set of benchmarking events. So formally, they could be considered a "Community". Yet, in some cases, projects may also group actual communities from different research domains.

Examples:

• "DREAM" space project
  • "Drug Resistance DREAM community"
  • "IPC DREAM community"
  • [...]
• "euCanImage" space project
  • "euCanImage" community

2 proposed strategies for modeling "Project spaces":

1. option A: creating a new "Projects" collection, with some fields covering common properties and with references to the list of associated communities. In most cases, "Projects" would link to a single community
2. option B: creating a new type of "Communities" or super-class of it.

During 11/02/22 internal meeting, option A was a priori preferred, but discussion is open.
