Hello,

    I don't intend to spark a bitter debate between XML & JSON, where the outcome of debate is win of one over other. Rather, I wish to present in a friendly manner, according to me, where these two technologies differ.

When talking about designing REST services, JSON seems to clearly win. The whole software world seems to be biased in favour of JSON it seems, for this criteria. Although I have read, that in many cases REST services can use XML instead of JSON. I think, JSON's major use case is in the use within REST.

Having worked quite a bit with Android mobile apps, that framework by default relies heavily on XML. I haven't seen JSON being used by default in that area. Although, JSON is many times used in feeding and fetching JSON data from various kinds of services (remote REST services, local API calls etc), in Android apps.

XML when considering other technologies in combination, like XML Schema and XML databases, have a scale close to RDBMSs. JSON is no where near this.

Any other thoughts from the experts here?
