The issue
There is no standardized way in Fedora to present a list of nodes in an arbitrary order defined by the user and stored in a dedicated property.
Michael Durbin, Unknown User (escowles@ucsd.edu), Stefano Cossu brought up the issue and expressed interest
Possible solutions
- Using MPTT/Nested Sets

- + Commonly used in relational database design
- - Complicated and maybe redundant in functionality
- - Slow updating nodes
- Using Ordered List Ontology
