Release v0.9.0

This release contains the results of two important developments adding a command line interface created by Miel Vander Sande (@mielvds) and applying the framework on the data of Deutsche Digitale Bibliothek. These two developments made the tool more robust, and more flexible so became applicable to different situations.

• To use the command line interface, download mqa and metadata-qa-api-0.9.0-shaded.jar, and follow the suggestions of the README.md file.
• new rules:
  • unique: checks if the value of the field is unique
  • dependencies: checks if other rules has already checked and passed
  • dimension: checks if a linked image fits to some dimension constraints (unit in pixel)
  • hidden: if the rule is hidden it will be calculated, but its output will not be present in the overall output
  • skip: prevents a particular rule to be part of calculation
  • debug: log the rule ID, value and result
• the schema is called MQA Schema. Some instances are available in the metadata-qa-ddb repository: https://github.com/pkiraly/metadata-qa-ddb/tree/main/src/main/resources
• important API changes:
  • the JsonBranch class has been renamed to DataElement
  • the OaiPmhXPath class has been renamed to XPathWrapper

The artefacts of the release are available in Maven Central as well: https://central.sonatype.dev/artifact/de.gwdg.metadataqa/metadata-qa-api/0.9.0
