Mulgara uses a system of indexing that has been called "Perfect Indexing", based on the 4 axes of:
  • Subject
  • Predicate
  • Object
  • Meta (or Model, which is more correctly called a Graph)

These are ordered indexes, stored in trees. The system is flexible and reasonably efficient.

Use cases have shown that Mulgara may achieve better performance. This area is for discussion of the structure and implementation of new indexing schemes.
