Search $value operations: add parameter language

[BirgitBoss]

What is missing?

Get/Search*$value operations: add parameter „language” with values “de” etc. to only display multi-language attributes in the language required by the application

Instead of

• Without query parameter language or with parameter language=”display-all-languages”:

{ "Label": [ { "de": "Das ist ein deutscher Bezeichner" }, { "en": "That's an English label" } ] }

• with query parameter language=“en“:

{ "Label": "That's an English label" } }

For getting all languages the language parameter shall have an additional reserved value, e.g. “display-all-languages”, this is the default for backward compatibility reasons

Note: There might be a label “ALL” besides “de” and “en” that means: this text shall be used independent of which language is required because it is the same in all languages. Example:

{ "Label": [ { "de": "ok" }, { "en": "ok" } ] }

• same as
  { "Label": [ { "ALL": "ok" }] }

• Case query parameter language=“en“:

{ "Label": "ok" } }
