In another "virtual panel session", we took the opportunity to talk with representatives of the new OASIS BPEL4People Technical Committee and get their feedback on just why we need this work. Apart from asking them what BPEL4People (and WS-HumanTask) are all about, we asked them how this relates to other BPMN efforts and what else we can expect in this area.
In an interview at OOPSLA, Dave Thomas talks about the reasons for the rise of Java, what's behind Web 2.0, MDA and SOA, the rise of dynamic languages and the opportunities that he sees in the web as a platform.
In his last blog post, Johan den Haan asks one of the key questions of model driven engineering. The article is didactic and explains how ontological and linguistic metamodels can be combined (orthogonally) to simplify code generation while enabling the combination of general purpose languages and domain specific languages concepts. He uses BPEL and BPMN as a supporting example.
OASIS is going to hold a 3 day symposium on the topic of "Composability within SOA" in Santa Clara, CA from April 28th to April 30th. Engineers and Scientists from vendors and end-user companies will discuss topics including mashups, Service-Oriented Ajax, SCA, BPEL, SDO, BPM, Web Service Transactions, Data Security in SOA, SOA Reference Architecture...
BPMN's adoption is increasing rapidly. In this post, we review some recent activity such as the publication of BPMN 1.1 by the OMG, a tutorial on how to use the Eclipse SOA Tools Platform to "Execute Business Processes" and a comprehensive 120 minute tutorial on BPMN by Bruce Silver.
Tom Baeyens, founder of JBoss jBPM gives his view of the state of the BPM / workflow market and introdces a new type of workflow technology called process component models.
In this new InfoQ article, Paul Brown introduces Apache ODE, an open source implementation of the WS-BPEL 2.0 standard. ODE differs from other BPEL engines in that it is delivered as a component rather than a framework for developers looking to add orchestration functionality to their systems. Paul introduces ODE's features by showing how to deploy and execute a simple process.
In this article, Boris Lublinsky discusses the main approaches to service composition, both from design and implementation point of view, and outlines the benefits of using orchestration. Topics covered include hierarchical vs. conversational composition, composition topologies, and the pros and cons of difference implementation approaches.
In this presentation, Google architect Gregor Hohpe introduces various concepts for to manage more complex interactions between services, including conversations, choreography, and orchestration. He provides a down-to-earth look at these concepts along with the associated Web services standards like WS-BPEL and WS-CDL, and identifies common patterns in service conversation.
Composite Software offers a new level of granularity when compared to SaaS (Software as a Service). Composite Software is about enabling "right-sourcing", i.e. move (or keep) arbitrary small or large elements of functionality wherever it is the most cost effective to operate them, not just entire systems. Economically, "right-sourcing" is far more efficient than "outsourcing" and SaaS. The goal of this book is start by understanding today’s software construction processes and technologies and explore why and how it should be evolved to support core composition mechanisms.
