Daisy Pipeline Release Notes

This document contains joint release notes for the DAISY Pipeline Core and the DAISY Pipeline GUI.

The DAISY Pipeline is a cross-platform, open source framework for DTB-related document transformations. It provides a comprehensive solution for converting text documents into accessible formats for people with print disabilities. The DAISY Pipeline project is fundamentally a collaborative multi-organization project, created by and for the DAISY community. It has been launched in 2005 and is maintained by the DAISY Consortium.

More information is available on the project home page.

New Functionality

Comments, suggestions and bug reports welcome!

  • New DTBook to RTF transformer and script, contributed by Ole Holst Andersen (DBB).

The script is available in the /conversion/simple/ category of the Script selector.

  • Initial version of an XHTML to DTBook transformer, contributed by Per Sennels (Huseby Norway)

This early version is provided for input and comments that will guide further development. The Script and Transformer documentation describes the current status and principles. Note * the DTBook output from this script is not yet ready for use; it will most likely be invalid.

The script is available in the /conversion/advanced/ category of the Script selector.

  • New DTBook Fixer transformer and script, contributed by Joel Håkansson (TPB), James Pritchett (RFB&D) and Linus Ericson (TPB)

This transformer will try to repair common problems in DTBook files; primarly problems that occur in files that are output from automated conversion processes, such as the WordML to DTBook Script.

The standalone script is available in the /manipulation/simple/ category of the Script selector. The DTBook Fixer transformer is now also included as a part of the WordML to DTBook, RTF to DTBook and ODF to Dtbook scripts.

  • New DTBook 2005-1 to DTBook 2005-2 migrator transformer and script, contributed by James Pritchett (RFB&D)

This is a part of the "DAISY Migration Suite" script collection, that will be finalized during 2008.

  • Improved DTBook to XHTML transformer, after a feature request from Chris Koch (ViewPlus Technologies)

The DTBook to XHTML conversion now has experimental support for the DTBook MathML extension. If the input DTBook file contains MathML, the output XHTML file will include MathML islands as defined by the W3C XHTML 1.1 plus MathML 2.0 plus SVG 1.1 profile.

  • Validation updates

The Z3986 DTB Validator now uses the latest ZedVal release (2.0 RC4, released 20071219)

Bug fixes ,stability and performance improvements

Too many to mention here, the full list can be reviewed online.

  • Added a full-blown welcome screen
  • Added a complete documentation

Changes in Core:

  • Minor bugfixes
  • Complete documentation

Pipeline Release Candidate, 2007-06-08

The development team initially intended to release a fully public release today, but due to an underestimated workload to get the Pipeline GUI and Core co- operating as desired, we have decided to delay the public release approximately two to three weeks.

Nevertheless, todays release is 100% feature complete, give or take some percents, and a still not finalized introductory first-launch welcome screen. Further, some bugs remain, and some documents remain to be written.

This release will be followed by a fully equipped release in late June 2007.

Changes in GUI

  • Fixed several bugs and accessibility issues. Many thanks to Avneesh for providing screen reader usage input.
  • Added preferences dialog
  • Added branding features (note - branding is not 100% complete.)
  • Developer oriented changes: substantial changes to build process

Changes in Core

  • Complete set of scripts for this release committed. Special thanks to Dave Pawson for helping to finalize the ODF to DTBook transform.
  • Added documentation (note - documentation suite is not 100% complete)

Pipeline Beta Release, 2007-05-25

The primary purpose of this release is to enable testing and evaluation of a new GUI. This release will be followed by a fully equipped release in mid June 2007.

Changes in GUI

This release contains the first public access to a new and redesigned cross-platform GUI, that runs on Windows, Mac and Linux platforms.

Changes in Core

  • Provisions of script-level (end-user oriented) documentation.
  • Support for jarness.
  • Miscellaneous refactorings and new transformers. Note * not all functionality is exposed in scripts shipping with this release.

Pipeline First Public Access, 2006-10-17

This is the second release of DAISY Pipeline. Some notable updates to the software is listed below:

Licensing

Software User Agreements for the DAISY Pipeline(both the DMFC and the GUI) provide specific licensing information regarding 3rd party software. As in all agreements, it is the obligation of the user to read and accept all such terms and conditions of all third party software packages prior to the use of the DAISY Pipeline.

WordML2DTBook

Version 1.4.1 (10 October 2006)

The most significant new feature in this release is that the converter now extracts images embedded in Word documents. Other enhancements include:

  • Automatic frontmatter creation: everything preceding the first heading will be part of the frontmatter.
  • Attributes: several attributes have been added or changed.
  • Customization: two new input parameters have been added: 'stylesheet' and 'images'.
  • Footnotes: The numbering of native footnotes have been improved

See the documentation for further information.

rtf2dtbook

Version 1.1 (13 October 2006)

The converter uses command-line python and not jython (the java-python bridge) to complete the rtf-to-xml transformation. The switch has increased the speed and reliablity of the transformer. In particular:

  • The rtf-to-dtbook transformer may be run more than once/session (resolution of issue #1543841)
  • The installation of the DAISY Pipeline does not terminate without notice (resolution of issue #1551549)
  • The rtf-to-dtbook transformer using python performs at many times the speed of the same transformer using jython.

Java Virtual Machine parameters

The default heap size is set to 128 MB (-Xms128m -Xmx128m). To set it to a different value, create a file named params.cfg in the installation directory containing a single line describing any parameters that should be sent to the Java virtual machine.

Resolved issues from the FPA Release

  • 1543841

Running the RTF-to-Dtbook script more than once during one session will make the application freeze. The transformer was changed to call python directly, instead of using jython, a java-python bridge. This allows the RTF-to-DTBook script to run more than once.

  • licenseinfo

The GUI does not yet provide information on specific licensing for specific scripts&transformers. A Software User Agreement for both the DMFC and GUI enumerates specific licensing for all transformers. The Software Agreement must be accepted prior to installation of the program.

  • installer

Running the windows installer as non admin makes it impossible to uninstall using the uninstaller. The windows installer may be run by admin or non-admin users, and the uninstaller works for both user types.

Pending features Below features are not yet implemented, but high on the list for the next release:

  • Access to transformer documentation from the GUI

Pipeline First Public Access, 2006-08-25

This is the First Public Access (FPA) release of DMFC.

Known Issues

Below issues are already identified and marked for fixing til next release:

  • 1543841

Running the RTF-to-Dtbook script more than once during one session will make the application freeze. The cause of the issue is known (#1543841) and will be fixed by next release.

  • 1543978

Running the int_daisy_unicodeTranscoder transformer with output encoding set to other than utf-8 or utf-16 produces incorrect representation of certain characters. The cause of the issue is known (#1543978) and will be fixed by next release.

  • licenseinfo

The GUI does not yet provide information on specific licensing for specific scripts&transformers.

  • installer

Running the windows installer as non admin makes it impossible to uninstall using the uninstaller. Workaround is to delete the install directory, and the link on the start menu.

Pending features

Below features are not yet implemented, but high on the list for the next release

  • Access to transformer documentation from the GUI
  • Specific licensing information when using particular 3d party libraries.
