The Document Foundation (TDF) is the charitable entity behind the world’s leading free/libre open source (FLOSS) office suite LibreOffice.

We are looking for an individual or company to clean up and further improve ODF conformance.

The default file format of LibreOffice is ODF, the Open Document Format. We have successfully tendered two projects on the current version 1.3 recently:

• The initial implementation of ODF 1.3 conformance
  Details: https://blog.documentfoundation.org/blog/2019/11/05/tender-odf-1-3-conformance/
• Various bits to finish the transition to ODF 1.3
  Details: https://blog.documentfoundation.org/blog/2020/10/20/tender-to-finish-transition-of-libreoffice-to-odf-1-3-odf-1-3-delta-202010-01/

The scope of this tender is to further improve the ODF conformance in LibreOffice. Note however that the majority of the items mentioned below are unrelated to ODF version 1.3, and have existed before support of this version was introduced in LibreOffice.

Deliverables

1. Get ODFAutoTests (https://gitlab.com/odfplugfest/odfautotests) to run again. Note: This item does not ask to setup a publicly available website.
2. Address one or more of the following high priority issues:
   1. “svg gradient” – Bugs 48392, 76682. Bug 48392 is prerequisite for Bug 76682.
   2. “list indent” – Bugs 78510, 92762, 114287, 83532, 82179, 145318
   3. “Math inline in text box” – Bug 129061. From user point of view it has highest priority.
   4. “numbered paragraph” – Bug 62032, 108868. The internal work is done. But a UI is missing. The expected UI needs to be specified.
   5. “ODF conformance part 1” – These are those errors, which are in most cases not visible for users, and therefore likely never included in a customer contract. Bug 53992, 101758, 103602.

   Please propose a subset and prioritization of these bugs, that do not exceed the person days factored in for this tender, see below.

3. Address one or more of the following lower priority issues:
   1. “ODF conformance part 2” Bug 106934, Bug 91472, 97706, 107253, 108536, 113404, 113554, 116321, 131148
   2. “Trailing space in cell text not encoded as <text:s/>” – Bug 113726
   3. “FILEOPEN PPTX: equation not displayed because Impress doesn’t support inline formulas”, in particular the as-char embedded object – Bug 129061
   4. “ODF database mime-type confusion” – Bug 45854
   5. “table: evaluates <text:variable-set> in body of float and void cells, but not of string cells” – Bug 68024
   6. “Implement ODF attribute fo:hyphenate to exclude a portion of text from hyphenation” – Bug 106733
   7. “FILESAVE: Form: incorrect ‘time’ type” – Bug 131127
   8. “FILESAVE: Date form: unexpected attribute ‘form:input-required’ – Bug 131148, cf. also https://issues.oasis-open.org/browse/OFFICE-4121

   Please propose a subset and prioritization of these bugs, that do not exceed the person days factored in for this tender, see below.

We expect bidders to provide documentation on both the code and the non-code parts of this tender, e.g. methodology, structure and technical aspects. The Document Foundation will publish this under a free and open source license and make it available to the general public.
