DeltaNI: An Efficient Labeling Scheme for Versioned Hierarchical Data

Summary: DeltaNI is a versioned NI labeling scheme for hierarchies, tightly integrated into the relational kernel. It provides space- and time-efficient, gapless fixed-size integer labels per version with branching histories, enabling scalable, query-friendly processing of large versioned hierarchies.
