SOAP 1.2 is out
The W3C has released the SOAP 1.2 Implementation. I still feel that XML-RPC Provides 99% of what everyone needs from an HTTP-based XML API protocol… but it seems that XML-RPC has been branded morefor homegrown applications, whereas SOAP is the “big-brother” version. XML-RPC is so much simpler.
Then again, sometimes a REST approach is perefectly fine.
OK, so that was a very open-ended opinion. Too bad. I think that REST, XML-RPC and SOAP all have their strngths and weaknesses and everyone should be able to use all of them, and know when to use them.
