XINS is a technology used to define, create, and invoke remote APIs. XINS is specification-oriented. When API specifications are written (in XML), XINS will transform them to HTML-based documentation and Java code for both the client-side and the server-side. The communication is based on HTTP. XINS competes with the complex SOAP technology. Main design goals include simplicity, scalability, and testability. XINS is not only a specification technology, but also an application development framework. It offers transaction logging, unique log documentation, and active code generation.
Dancer is a Perl framework for building Web applications with minimal effort. It started as a port of Ruby's Sinatra project, but has grown on its own path. A Dancer app can run as a standalone Web server or from any Web server using PSGI. It lets the user write an application with very few lines of code. It's powerful and flexible enough to knock up a simple Web site or Web service very quickly, and can scale to much larger projects. Building a Web application with Dancer is as easy as loading the library and defining route handlers. Dancer provides an elegant syntax for defining route handlers, can render views with a variety of template engines, supports static file serving, session support, and many more features.
