INSPIRE provides guidance in this respect, any request that can be affected
by internationalization must support
a direct request parameter specifying the language, from the spec:
--------
The name of this parameter shall be “LANGUAGE”. The parameter values are
based on ISO 639-2/B alpha 3 codes as used in [INS MDTG]
--------
For example:
http://inspire.network.service.example/service?SERVICE=[...]&VERSION=[...]&LANGUAGE=eng
This is however for the capabilities request. For other operations the
guidance says:
------------------------
For further language support for other operation it is
recommended to replace the operation-online-resources in each language
specific GetCapabilitiesResponse by a specific operation-online-resource
for that language. To support the additional
operation-online-resources the service shall listen at the language
specific operation end-points to
distinguish for the requested languages.
------------------------
Which, imho, would be easily implemented if we allow the language to be a
KVP param in all requests,
so that code specifically interested in language issues can access it
either as part of the request object
(GetLegendGraphics case) or as a thread local.
Regardless of the specific solution I'd try to keep it uniform for all
services and methods, whilst legend_options
is specific to GetLegendGraphics.
Cheers
