Summary of changes for version 4.1

  • Changed schema version to 4.1
  • Fix for Processing including processingStepType.
  • Add missing PROCESSINGREFS to PageType, PageSpaceType, BlockType, TextLine, StringType for referencing Processing history.

Version 4.1 was released in May 2019.

You can find the version 4.1 schema here.

Comments about the schema and its documentation as well as additional use cases for the new schema features are encouraged (GitHub account required).

ALTO schemas will be updated by whole numbers upon making changes that break backward compatibility (version 1 to version 2), and decimals for changes that will not (3.0 to 3.1). The namespace itself will also only change on major versions (ns-v2 to ns-v3).
