Observatory Service Broker Contributed to CECID

CECID Contributes OSB Service Bus to CECID Community Website

Hong Kong SAR, Peoples Republic of China. 4-February-2008.

Center for E-Commerce Infrastructure Development (CECID), The University of Hong Kong (HKU) contributes Observatory Service Broker (OSB) to CECID open-source community website.

Thanks to ITF funding, the Observatory Service Broker (OSB) is one of the project deliverable of Project Plumber. The OSB is an enhanced version of a process-driven enterprise service bus, which supports a choreography-based business process. It is based on a published Java standard: Java Business Integration (JBI).

JBI is a Java-based standard addressing the EAI and B2B issues based on the paradigms and principles advocated by SOA. It defines the standards for composite plug-ins in SOA architecture, as well as how the plug-ins can communicate with each other. Along with the OSB, there is a Business Process State Tracking (BPST) engine registering the rule sets to guide the execution of business processes and keep track the state of each rule set. [Reference: Java Specification Request 208: Java Business Integration (JBI); see Wikipedia]

OSB, BPST and their source codes ( are released to CECID open-source community website under GNU General Public License Version 2. Later on, useful information and articles ranging from technical issue to general usage of OSB will be available at the community website. In addition, professional support is provided by CECID's VARs and can be requested through email [at]
