Hydro is an independent implementation of ICE, the object-oriented RPC protocol by ZeroC, for the O'Caml programming language. Hydro (like ICE) allows you to bridge language barriers by letting components written in different programming languages communicate with each other. ZeroC's ICE product currently includes implementations for C++, Java, C#, Python, Ruby, VB, and PHP. Hydro adds support for O'Caml. Hydro includes an asynchronous runtime and a generator called hydrogen.
PMS/PyPubSub (short for Python Message Service / Python based Publish Subscribe) is a framework for implementing a publish subscribe mechanism into a Python application. A python process somewhere in the network publishes one or more topics which consist of Python objects. Multiple processes in the network can subscribe to fresh updates of the published topics. A publisher and its subsribers are fully decoupled. The datatype of a topic can be freely defined and changed at runtime. New publishers and subscribers can easily be added at runtime.
TIDorb C++ is a CORBA 2.6 ORB with a high level of stability and performance. It fully implements Portable Object Adapter (POA), IIOP protocol (versions 1.0, 1.1, and 1.2), including bi-directional communications, MIOP protocol (IIOP over udp/multicast), ZIOP (zipped IIOP), SSLIOP (SSL over IIOP), CSIv2, the Dynamic Anys API, DII dynamic invocation interface, and DSI dynamic skeletons APIs, the static invocation API, OBV (object by value passing), and some CORBA messaging QoS policies, and it partially implements RealTime functionalities and Codecs.
TAO is a standards-compliant, real-time implementation of CORBA that provides efficient, predictable, and scalable quality of service (QoS) end-to-end. Unlike conventional implementations of CORBA, which are inefficient, unpredictable, non-scalable, and often non-portable, TAO applies the best software practices and patterns to automate the delivery of high-performance and real-time QoS to distributed applications.
The Simple components for Ada library provides implementations of smart pointers for automatically collected objects (using reference counting), object persistence, unbounded and bounded arrays of smart pointers, generic unbounded arrays of private objects and plain pointers, generic sets, maps, directed graphs, directed weighted graphs, stacks, and storage pools. It also includes table management, string editing, IEEE 754 support, and infix expression parsing tools. Implementations of some lock-free shared data structures are provided.
XmlBlaster is XML based MOM (Message oriented Middleware) with a lot of features. It is a publish/subscribe and point-to-point MOM server which exchanges XML-encoded messages. Communication with the server is based on CORBA (using JacORB), RMI, XML-RPC, native socket, or a persistent HTTP plugin. Subscribers can use XPath expressions to filter the messages they wish to receive and add their own MIME-based filter plugins. C/C++, Java, Perl, Python, VisualBasic.net, C#, and PHP client demos are included in the xmlBlaster test suite, and Tcl and Python demo clients are scheduled. XmlBlaster also provides a browser callback framework, allowing browsers (Netscape, Mozilla, MSIE) to receive instant callbacks over a persistent http connection. A security plugin framework allows authentication/authorization in many ways. Currently there are LDAP- and passwd-based plugins available.
xmlrpc-c is a programming library for writing an XML-RPC server or client in C or C++. XML-RPC is a standard network protocol to allow a client program to make a simple remote procedure call (RPC) type request of a server. It's like SOAP or CORBA, but much simpler. This library speaks the same XML-RPC as similar libraries for lots of other programming languages, with most of the popular extensions. The client library uses either w3c libwww or Curl for HTTP. The server library contains a complete lightweight HTTP (Web) server and also facilities for running with CGI under any Web server.
