OOX Packages and Zip Specification

  • Rumaging in the ECMA TC45 Office Open XML Document Interchange base document (OOX base, for short), I noticed that there is not much about the Zip model and the constraints that may apply for its use in carrying OOX Packages. 

    For those who are interested, the PKWARE Application Note on the ZIP File Format Specification can be found via http://www.pkware.com/business_and_developers/developer/appnote/ and, if you have Active Scripting disabled during the present emergency, the actual page is http://www.pkware.com/business_and_developers/developer/popups/appnote.txt and the current version is 6.2.2 dated 2006-01-06.

    As part of my general interest in OPC and the OOX Packages, I am assuming that the ZIP Appnote Clarification in the Open Packaging Convention 0.80 draft (December 2005) apply.

    Although it is not an urgent concern, I was wondering if manipulating OOX Packages necessitates use any of the technology for which PKWARE says a license is required.  It is something I would want to keep in mind for any programmatic access and creation done outside of WinFX/WPF (say in a multi-platform interoperability library) and it would be useful to know the boundaries more sharply than given in the brief mentions in the PKWARE Application Note on ZIP.

  • Regarding your concern of manuplating OOX packaging say in a multi-platform interoperability, I feel you should be able to use the Java's packaging libraries abailable in java.util.zip.
