Subject: [OASIS Issue Tracker] Commented: (OFFICE-2532) Public Comment: Zipcompression algorithms (ODF, all versions)

    [ http://tools.oasis-open.org/issues/browse/OFFICE-2532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18483#action_18483 ] 

Michael Brauer commented on OFFICE-2532:

More specifically I suggest that we 

- add the following to (PD1.1): All files contained in the ZIP file shall be non compressed (STORED) or compressed using the DEFLATE algorithm.
- add the following to (PD2):  Files contained the the package may be compressed with other algorithms than DEFLATE.
- adapt the definition of extended conforming documents in part 1 to:
(D2)A conforming OpenDocument extended document shall meet all requirements of a conforming document except *(D1.1.1),* (D1.2.3), (D1.3.3), and (D1.5) and shall meet the following requirements:
(D2.1) [new clause] If the document is an OpenDocument package, then it shall be a conforming ODF extended package as defined by the OpenDocument specification part 3: Packages.

This means that in a conforming package, only DEFLATE or no compression is allowed, while in extended conforming packages, other algorithms are allowed. The same applies to ODF documents. In an ODF document, only DEFLATE is allowed, while extended document may use other algorithms.

Since this is a non-trivial change I add an NEEDS-DISCUSSION here so that the proposed resolution gets your attention.
