Re: SOAP vs. REST

[Scott Klement <web400@xxxxxxxxxxxxxxxx>]

Jim,

SOAP reached its peak popularity in 2004, has been on the decline ever 
since.  Currently about 15% of APIs are SOAP, and 75% are REST.   
(Everything else makes up the remaining 10%)

So... REST is what everyone uses today.  The only reason I'd consider 
SOAP is if a client specifically wanted it and couldn't be talked out of it.

With regards to data format, JSON is currently more popular than XML, 
and I also prefer JSON.  However, I must admit the difference between 
JSON/XML is nowhere near as important as the difference between SOAP and 
REST.  JSON will result in smaller documents that, therefore, transfer 
over the network faster.  It's more efficient to process in web 
environments (such as AJAX/Web2.0) because it's a subset of JavaScript, 
which is what browsers are optimized for.  But, XML works okay, too.
