@melaasar melaasar released this 07 Jul 04:00

(Note: skip this release in favor of v0.9.2 due to a bug with catalog resolution that got introduced here and fixed in v0.9.2)

This release involves some breaking changes:

  • oml.FeatureProperty has been renamed to oml.SemanticProperty
  • oml.EntityPredicate has been renamed to oml.TypePredicate
  • oml.RelationPredicate has been renamed to oml.FeaturePredicate
  • oml.Feature is a new abstract supertype of oml.Property and oml.Relation

This release also contains improvement to the rule support in OML. In particular:

  • you can now add a single-variable predicate on any type (not only entities), e.g., structure(x), scalar(x)
  • you can now add a two-variable predicate on any feature (not just relations), e.g., scalarProperty(x, y), structuredProperty(x, y)
