Release Notes

The purpose of this section is to provide a description of a Validation Tool release including any impact that the new or modified capabilities will have on the Discipline Nodes or the PDS user community. A somewhat itemized list of changes for each release can be found on the Release Changes page.

Release 1.1.0

This is a maintenance release of the Validation Tool including fixes and changes requested by the early adopters of the application.

The major changes for this release are as follows:

  • First release of the project under the name vtool .

    The Validation Tool application has been split out from the product-tools project in order to provide more specific documentation and to turn the product-tools project into a library of classes that can be included by other projects.
  • Detailed exit status values

    The exit status values have been augmented t o provide a more detailed representation of the status from a validation run on the command-line. Please review the Exit Status Values portion of the Use and Operations section for the details.
  • Specific GROUP definition support

    Added support for the use of SPECIFIC_OBJECT_DEFINITION in GROUP definitions specified in a data dictionary.
  • Elements may not be duplicated

    An element may not be duplicated within a given block of a label. An error message will be generated stating that multiple elements of the same name were found.
  • Unit handling

    Messages regarding unknown unit values will now have a severity of WARNING instead of ERROR.
  • Documentation Updates

    Added the release notes to the PDF version of the Validation Tool Guide and included a README file in the binary distribution package.

The liens for this release are the same as they were for release 1.0.0, except that the Development Guide is now a lien against the product-tools project.

Release 1.0.0

Although this release pertains to the product-tools project, its description has been retained here for completeness.

This release of the Product Tools software, including the Validation Tool, represents the operational release for the Phase I targeted capabilities. The tool currently supports data product label validation including syntactic validation against the grammar and semantic validation against the PDS data dictionary.

The major changes for this release are as follows:

  • Sub-objects supported in explicit FILE objects

    Although the tool didn't require any changes, SCR 3-1089 was approved and implemented in re lease 1r66 of the PSDD, enabling this capability.
  • Report Fine Tuning

    The majority of changes for this release involved fine tuning the reporting capability. The parameters related to reporting in this release have been modified to support these changes.
  • Executable Scripts and Exit Status Values

    Batch and shell scripts have been provided with this release allowing for simpler execution of the tool. Exit status values are now returned by the tool enabling execution from a script.

The liens for this release are as follows:

  • Checking for Label Padding

    Validation of proper label padding has not been implemented yet.
  • Summary Report Message Ordering

    The summary report still lists the messages in alphabetical order instead of the preferred chronological order.
  • Date/Time Interpretation

    When running the tool under Java version 1.5, date/time values are periodically interpreted incorrectly generating an error message in the resulting report. This appears to be a bug in Java version 1.5, but we will research it further to determine a workaround or fix for the next release.
  • Developer Guide

    Although a minimal Development guide is available in this release, it still needs content detailing the entry points for the API.
