Note that the first two entries share the same value of atom:updated,
this is a SHOULD-Level violation of section 4.1.1. I think the spec
should allow multiple entries with the same timestamp iff they
differ by
language and/or content-type. In multilingual countries like
Switzerland
it is required (as for laws) or at least a matter of political
correctness (as for press releases) for some publications to be
published at the same time in all language versions.
Why not publish content negotiated atom feeds, so that the French
version
of the feed only contains french entries, the German version only German
entries, the Italian one only Italian ones, and the Romansh one only
Romansh
entries? Then the user would subscribe to the feed serving the
entries in
the language preferred by the author.
Of course since in Switzerland the German, French and Italian
representations
of the feed have to appear simultaneously they will each contain
entries with
identical ids and identical atom:updated time stamps. This would not
contradict
the atom spec which mentions only that in a particular feed document two
entries with the same id should not have the same updated time stamp.
It is
something on the other hand that an ontology of atom would have to be
careful
about (or a database consuming atom feeds), as it would have to take
into
account the possibility of multiple language versions of the same
update of
an entry.
