Change Log

[2.0.6] - 2021-06-27

Added

• A new CLI for loading data and executing queries. This builds natively with GraalVM.
• Exposing now and instant? from asami.core
• Serialization of arrays and maps. This will enable upcoming features.
• An :id attribute can now be used as a synonym for :db/ident. These values are not removed from entities, unlike the :db attributes.

Fixed

• Aggregates correctly group even when selections are not sensible.

Changed

• Integrating entity code fully into Asami. This is no longer imported from Zuko.
• Minor efficiency improvements to in-memory updates and reads.
• Booleans are now encoded into IDs and no longer serialized.

2.0.5 - 2021-05-27

Changed

• Entity conversion to statements is no longer recursive on arrays. This allows for larger arrays.

Fixed

• Fixed missing functions on read-only trees

2.0.3 - 2021-05-06

Fixed

• Fixed problem where the internal node IDs were not initializing from saved transactions.

Fixed

2.0.0-alpha2 - 2021-03-09

Added

• Internal node type. This avoids the need for interning keywords as nodes.

• Fixed problem that duplicated optional constraints during query planning.

• optional operator, as per the SPARQL OPTIONAL operation.
• Added show-plan function to observe how a query will be performed.
