This is a project concerning a general underlying combinatorial interface for our datastructures. ( @moussa @do @tyburn @blume @rancic @gietz )

@tyburn is leading this project.

This project includes

• introducing a new datastructure
• adding attribute mechanism to datastructure

Initially these tasks where described in

• #480 general combinatorics interface
• #515 general attribute mechanism for combinatorial interface by implementing a new structure. Currently we are looking for a third party library for this. Nevertheless this should suffice all the points in these two issues.

Apart from Geometry central interesting libraries are listed in

• #542 interesting libraries

Timeline

• 2023-04-03 - P (Geometry central prototype)
• 2023-04-24 - P (python prototype)

Related ideas and isssues(these will be assigned to this Milestone but do not (necessarily) have to be treated within but should be moved to a new project/issue once this is finished)

• replacing old datastructures
• #576 Proposal to remove co_attr="co" keyword arguments from functions
