LDM

LDM (Lua Data Model) aims to be a module to help working with what I call the Lua data model: tables and values that build graphs, DAGs¹, trees, lists, etc.

Some aimed features:

• Clone / copy.
• Object / value identity, equality.
• Full or incremental² delta, snapshots.
• Transformation of a general graph to a tree that can be serialized, e.g. by MessagePack or LuaJIT's string buffers.
• Schema definition and full or incremental validation.

1. ^{^} Directed Acyclic Graphs
2. ^{^} Full would be about computing the delta between two given tables in one pass and incremental would be about building the delta continuously when data is modified.
