0.20.0

• Allow editing inferred attributes (see Wiki for details) (Feature #121).
• Support for IN, NOT LIKE, <> (!=) operators in SOQL (and the corresponding operators in Criteria API). (Enhancement #123, #129).

0.19.3

0.19.2

• Fix issues in working with LocalTime values.

0.19.1

• Fix issues in working with BigInteger and BigDecimal values.
• Fix a warning about illegal reflective operations on newer JDKs.

0.19.0

• Add support for disabling inference via query hints (Enhancement #101).
• Allow registering custom attribute converters (Enhancement #118).
• Add RDF4J driver, deprecate Sesame driver (Task #75).
• Dependency updates: SLF4J 2.0.3, Logback 1.3.4.

Both query hints and custom attribute converters are covered by the Wiki documentation.

Upgrade Notes

The Sesame driver (artifactId ontodriver-sesame) has been deprecated. Its usage should be replaced by the new RDF4J driver (artifactId ontodriver-rdf4j). It is currently functionally almost equivalent to the Sesame driver (with the exception of support for disabling inference for query execution). However, further development will focus on the new driver, so it is highly recommended to migrate to it.

To migrate, do the following:

1. Maven

Replace

<dependency>
  <groupId>cz.cvut.kbss.jopa</groupId>
  <artifactId>ontodriver-sesame</artifactId>
</dependency>

With

<dependency>
  <groupId>cz.cvut.kbss.jopa</groupId>
  <artifactId>ontodriver-rdf4j</artifactId>
</dependency>

2. Java

Replace the following class references

1. cz.cvut.kbss.ontodriver.sesame.SesameDataSource -> cz.cvut.kbss.ontodriver.rdf4j.Rdf4jDataSource

And the following properties:

1. cz.cvut.kbss.ontodriver.sesame.use-volatile-storage -> cz.cvut.kbss.ontodriver.rdf4j.use-volatile-storage
2. cz.cvut.kbss.ontodriver.sesame.use-inference -> cz.cvut.kbss.ontodriver.rdf4j.use-inference
3. cz.cvut.kbss.ontodriver.sesame.load-all-threshold -> cz.cvut.kbss.ontodriver.rdf4j.load-all-threshold
4. cz.cvut.kbss.ontodriver.sesame.repository-config -> cz.cvut.kbss.ontodriver.rdf4j.repository-config
5. cz.cvut.kbss.ontodriver.sesame.reconnect-attempts -> cz.cvut.kbss.ontodriver.rdf4j.reconnect-attempts
6. cz.cvut.kbss.ontodriver.sesame.inference-in-default-context -> cz.cvut.kbss.ontodriver.rdf4j.inference-in-default-context

or switch from the SesameOntoDriverProperties constants to Rdf4jOntoDriverProperties constants (note that they do not have the SESAME_ prefix).

0.18.7

• Fix support for custom datatypes in Jena driver (Bug #113).
• Fix mapping enums to simple literals (Bug #111).
• Fix an issue with double-wrapped indirect collections when cloning singleton Maps (Bug #114).
• Dependency updates: RDF4J 3.7.7

0.18.6

• Automatically resolve inferred statements contexts for GraphDB (Enhancement #106).
• Allow configuring Sesame driver to load inferred statements from the default context (See wiki for details).
• Move supported identifier types constants from jopa-impl to jopa-api module.
