7.2 JSON encoding
Not much work has been done in OWS9 to develop this encoding. One of the ideas was to generate a JSON encoding from the XML encoding using an XSLT. The OWS context
SWG has produced some examples on how this can be done, but it is still in progress.
The generation of a JSON encoding seems to be adequate for the use on JavaScript clients. Nevertheless, 2 difficulties are foreseen:
Some OWS service requests need to be produced in XML encoding such as HTTP POST and HTTP SOAP. Sometimes there is no equivalent in KVP. This
operation requires an XML payload that does not currently have JSON encoding. Even if we can generate one, the actual request to the servers will require a
conversion back to XML.
The main in-line content examples that have been produced so far are in GML or KML. Both are XML encodings with no direct equivalence in JSON. The use of
