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.
QoS Enabled Distributed Objects implements a CCM and adds some more advanced features such as QoS extensions and interoperability with other middleware technologies. Please note that you also need the generator for implementing your own components, and it can be found at the same place.
Quality Objects (QuO) is a framework for providing quality of service (QoS) in network-centric distributed applications. These applications range from embedded applications to wide area network applications, including many military and commercial applications. QuO bridges the gap between the socket-level QoS being specified, researched, and provided by a number of organizations and the distributed object level where many distributed applications are best written. QuO adds QoS to CORBA and Java RMI in a manner which is appropriate for creating applications that can adapt to environments that are unpredictable or have strict resource constraints.
QML (Quantity Modeling Language) is a "thing"-based language for scientific and mathematical data modeling. Each "thing" is a quantity which may be associated with either a structure or physical phenomena. Quantities, in turn, may hold other Quantities or values (numbers or strings). Higher-level data models, which associate or define meanings to various quantities (such as velocity or position), can be built from QML quantities. The higher-level data model (XML) schema that inherits from QML may be understood, and its instance documents may be parsed into QML documents and objects by the QMLReader.
QOF (Query Object Framework), provides a set of C Language utilities for performing generic structured complex queries on a set of data held by a set of C/C++ objects. This framework is unique in that it does not require SQL or any database at all to perform the query. Thus, it allows programmers to add query support to their applications without having to hook into an SQL database.
RMIIO is a library that makes it as simple as possible to stream large amounts of data using the RMI framework (or any RPC framework). The RMI framework makes it very easy to implement remote communication between Java programs, yet does not provide any ready solutions for sending large files without blowing out memory on the client or server. What you really want to do is stream data from the client to the server using a framework that does not really expose streaming. The RMIIO library provides some very powerful classes that enable a client to stream data to the server using only a few extra lines of code.
RestfulBeans is a high level API for sharing objects between a server and a Java-based client. The underlying protocol is designed to expose the data consumed by a rich client to the search engines. The key properties of the protocol are compliance with the HTTP spec and REST principles, and XML representation for Java Beans with object references represented as XLink (to allow search engines to walk through the object tree). The key API property is the ability to work with remote objects as if they were local. An application using RestfulBeans is automatically capable of supplying users with URLs for any “content item” it deals with.
