veraPDF 0.26 Release

Version 0.26 (November 16, 2016)

We've made two downloads available for out 0.26 release. There's the ususal version, based on Apache PDFBox and downloadable from: http://downloads.verapdf.org/rel/verapdf-installer.zip. For 0.26 we've also prepared the first beta release of our purpose built PDF parser and validation model, also known as the greenfield validator. This is downloadable from: http://downloads.verapdf.org/gf/verapdf-gf-installer.zip. It's not functionally complete yet as it only supports PDF/A validation. Full details of the release features are listed below.

Conformance checker

• added the new rule for embedded files to be associated with the document or its parts (PDF/A-3 only).

Application enhancements

• first beta release of greenfield PDF/A validation available as a limited functionality app;
• refactoring of sub-component and application configuration for reproducible execution;
• new BatchProcessor producing multi-item reports;
• batch processing is stream/event driven with event handlers for processing results; and
• report structures altered to accommodate batch processing.

Code Quality

• publication of integration tests for Greenfield components;
• memory usage and execution times in test reports;
• example test report available here at time of writing: http://tests.verapdf.org/0.26.8/

Test corpus

• added 7 new test files to cover the new rule in PDF/A-3 validation profile

Disabled functionality

In order to accommodate batch reporting for this release we've had to sacrifice
redirecting output to user files. This isn't permanent and will be re-instated for the next release. The following functionality has been temporarily disabled:

Standard release

• HTML report from CLI, HTML reporting will be a function of the dedicated reporter in the next release. HTML reports are still available from the GUI;
• the -pw option that allows the user to override the profiles wiki, this was only used to generate the HTML report so is not required;
• the -c load config option, config is automatically loaded from the app area and we're adding user config to the next release;
• the --reportfile, --reportfolder, and --overwriteReportFile as these need a rethink to accommodate batch processing.

Greenfield release

The Greenfield release is missing all of the above plus:

• metadata fixing in GUI and CLI; and
• feature extraction in GUI and CLI.

veraPDF 0.24 Release

Version 0.24 (October 11, 2016)

Conformance checker

• added extraction of the AFRelationship key for embedded files as a part of veraPDF feature extraction.

Application enhancements

• implemented prototype of batch validation from CLI and GUI;
• implemented robust handling of run-time exceptions during batch processing; and
• added error info on the run-time exceptions to the validation report.

Code Quality

• moved feature extraction and metadata fixing code to library; and
• tidied various compiler warnings.

veraPDF 0.22 Release

Version 0.22 (September 7, 2016)

Application enhancements:

• changed default feature generation to document level features
• added a new GUI dialog for managing feature generation options
• added a user-friendly Java OutOfMemoryError with suggestions for reconfiguration
• CLI can now overwrite report files
• added help message when CLI processes STDIN stream
• synchronized the Web demo validation report with the CLI and GUI report styles

• implemented resource caching for memory optimization

Test corpus:
