# What is the PDFX namespace, you might ask? I might ask that too. It's
|
||||
# a completely undocumented namespace used to place "custom metadata"
|
||||
# properties, which are arbitrary metadata properties with no semantic or
|
||||
# documented meaning. Elements in the namespace are key/value-style storage,
|
||||
# where the element name is the key and the content is the value. The keys
|
||||
# are transformed into valid XML identifiers by substituting an invalid
|
||||
# identifier character with \u2182 followed by the unicode hex ID of the
|
||||
# original character. A key like "my car" is therefore "my\u21820020car".
|
||||
#
|
||||
# \u2182, in case you're wondering, is the unicode character
|
||||
# \u{ROMAN NUMERAL TEN THOUSAND}, a straightforward and obvious choice for
|
||||
# escaping characters.
|
||||
#
|
||||
# Intentional users of the pdfx namespace should be shot on sight. A
|
||||
# custom data schema and sensical XML elements could be used instead, as is
|
||||
# suggested by Adobe's own documentation on XMP (under "Extensibility of
|
||||
# Schemas").
|
||||
#
|
||||
# Information presented here on the /pdfx/ schema is a result of limited
|
||||
# reverse engineering, and does not constitute a full specification.

By default, some web browsers unfortunately do not include the territory
|

in the locale identifier for many locales, and some don't even allow the

user to easily add the territory. So while you may prefer using qualified
|
||||
locale identifiers in your web-application, they would not normally match
|
||||
the language-only locale sent by such browsers. To workaround that, this
|
||||
function uses a default mapping of commonly used langauge-only locale
|
||||
identifiers to identifiers including the territory:
|
||||
|
||||
>>> negotiate_locale(['ja', 'en_US'], ['ja_JP', 'en_US'])
|
||||
'ja_JP'
|
||||
|
||||
Some browsers even use an incorrect or outdated language code, such as "no"
|
||||
for Norwegian, where the correct locale identifier would actually be "nb_NO"
|
||||
(Bokmål) or "nn_NO" (Nynorsk). The aliases are intended to take care of
|
||||
such cases, too:
|
||||
|
||||
>>> negotiate_locale(['no', 'sv'], ['nb_NO', 'sv_SE'])
|
||||
'nb_NO'
|
||||
|
||||
You can override this default mapping by passing a different `aliases`
|
||||
dictionary to this function, or you can bypass the behavior althogher by
|
||||
setting the `aliases` parameter to `None`.
