Apache Tuscany SCA Runtime
==========================

Tuscany SCA Native is an SCA (Service Component Architecture) runtime written
in C++ and integrated with the Apache HTTPD server.

It supports SCA components written in C++ and Python. Experimental support
for other programming languages is under construction. SCA bindings are
available for the JSON-RPC, ATOMPub and RSS protocols. User signin is
implemented using OpenID and OAuth.

Several useful SCA components are provided on top of the SCA runtime, which
can be used to help assemble distributed SCA composite applications:

Cache: key/value memory cache, using Memcached;
Chat: XMPP chat, using Apache Vysper and Libstrophe;
Filedb: key/value 'NoSQL' persistent store, using plain files;
Http: HTTP client, using Libcurl;
Log: distributed logger, using Facebook Scribe;
Nosqldb: key/value 'NoSQL' persistent store, using TinyCDB;
Queue: AMQP queuing, using Apache Qpid/C;
Sqldb: SQL database, using PostgreSQL;
Webservice: Web service gateway, using Apache Axis2/C.

These components present a simple ATOMPub REST interface, allowing you to send
a message to a queue, a chat connection, or add an entry to a cache or a
database for example, using a simple HTTP POST.
