Unless I'm overlooking something, I think SOAP is a little overkill for Xindice since the data returned will most likely always be XML and not a datatyped response. What do you guys think?
The one thing that is appealing about SOAP is that it supports multiple encodings so it would enable something like our XML:DB API impl to negotiate with the server to use a binary encoding while less intelligent clients use regular encodings. Right now one of the benefits of the CORBA API is that it doesn't parse the document if it doesn't have too, with SOAP you could achieve the same thing. We could actually achieve the same effect with XML-RPC through a method on a parameter, but that alters the interface.
That being said, I really prefer to take as simple of an approach as possible to start with and that is really XML-RPC. So I'm +1 for XML-RPC.
Apache XML-RPC does have a web server class that could probably handle some of the other concerns about using HTTP as the transport:
1. ability to deny requests based on remote IP 2. SSL support
SSL is going to be required when security is implemented , otherwise db usernames and passwords would be sent in plain text.
For the next release I think we should just keep the existing HTTP server.
The current XML-RPC interface is really simple in that scenario. We can look at moving to something else once we start to convert over to Avalon.
The two server "plugins" both use the HTTP server. (HTTP Doc retrieval and
the XML-RPC plugin).
Speaking of the XML-RPC plugin, I apologize for not having a download available. I will have some CVS updates and hopefully a download later today:
Do you want to continue to own this piece? I'm thinking we use the existing interface as a starting point and roll it into the server for the next release. Thoughts?
We should reexamine the details of the API but it's a really simple place to start. I'm comfortable with proposing you for commit based on your existing work if you want to continue improving on it?
