I don't have a strong opinion but it should be one of the following IMO:
1) we don't care about the date in XML (which is the current situation
in practice since we never ruled on this and we don't apply the same
rule)
2) XAR format forces a specific date in the XML (but hard to find one
that make sense)
3) XAR format remove the date element from the XML (which means that
the date will be the install/import date)
4) the date in the XML is the date of the last commit (but hard to
make sure it's always true, maybe some git tag like the id tag we are
using in Java files ?)
5) the date in the XML is the release date (means adding this in the
release script but it's a pity for extensions)

Hi, devs,
This interesting discussion [1] came up recently on a github commit that
lead us to realise that a practice which we have been doing since forever
is not documented in our best practices guides and that we also seem to
lack consensus on it.
It`s about the practice of skipping date field changes from document XML
pages when committing them to source control. This includes doc date
and contentUpdateDate
fields, but also attachment dates.
You can see some arguments on the discussion[1], but I also wanted to
mention that this practice goes in line with what we do for document
versions (which is handled by the xar:format maven plugin goal which we
execute every time, before committing XML pages).
If we are to update doc
dates, then we should also increment doc versions, otherwise it does not
make any sense.
No, there is no relationship between the version and the date in this context.
The idea was, AFAIR, that XWIki`s code pages should not generate any
updates in the user`s wiki content, in any way, and that and update of the
code of a "system"/XWiki page should not show up as an update of *the
user's content*, since it would otherwise confuse him.
What we are currently missing from xar:format is exactly this: the reset of
XML page dates to have a clearer and more consistent date for XWiki`s code
pages.
But which date ?
Your input is appreciated and the result of this discussion would be the
update of our Development Practices [2] and Application Development Best
Practices [3] pages.
Thanks,
Eduard
