Discuss types of Orbit Relationships

[wyc]

What kind of orbit relationships can exist? Some examples:

• Copy-on-Write orbits that are based on another orbit
• Composite orbits that are composed from one or more other orbits, possibly with a Copy-on-Write orbit serving as a sink for changes.
• Partial orbits which contain a subset of other orbits
• Projected orbits which are mapped from other orbits to change content identifiers or other aspects
• What else?

Questions:

• How do permissions work across orbit relationships?
