Greetings from Beijing.<br>
<br>
Thank you for reminding me about my earlier contribution. I have
looked at this again and have two observations:<br>
<br>
1) The requirement for consumers to "not fail to load a document
containing unknown relationships" is in §9.1.7 of Part 1. <br>
2) This same clause makes it clear that consumers that are also
producers "can, but are not required to roundtrip and preserve
unknown relationships and their target parts".<br>
<br>
This means that the divergent behaviours of MS Office and
LibreOffice is allowed by the standard.<br>
<br>
This divergent behaviour applies regardless of whether the unknown
relationship is added to the package-relationship item or is added
to the main document part-relationship item (see §11 of Part 1).<br>
<br>
I have considered the "guidance" provided at the end of §9.1.7 of
Part 1, to "use instead the known relationship type for Custom XML
Data Storage parts", as defined in §15.2.4. However, I'm not sure
of the status of this feature - I don't believe it is implemented
any longer due to IPR issues - so we should consider whether it
would be best practice to ignore this guidance and just use
unknown relationships for incorporating foreign parts that aren't
able to use any other known relationships.<br>
<br>
Kind regards,<br>
<br>
Francis<br>

<p class="MsoNormal"><span style="color:#1F497D">I have one
immediate set of thoughts about the MCE Best Practices
document – which goes back to the topic of embedding rich
metadata in OOXML packages. I’m attaching what I believe to
be the last email (from Francis) on that topic. Francis’s
email points out that LibreOffice does not preserve foreign
parts (or the version he tried didn’t). Is the Best
Practices document intended to encourage LibreOffice to
preserve them? <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Has using rich
XML metadata been considered as a second example of a
foreign part? I would very much like to see that added.
ONIX (as used by Francis) is a good example for a DOCX
document. ISO 19139 (Geographic Information – Metadata –
XML schema implementation) might be appropriate for an XLSX
document.<o:p></o:p></span></p>
