Introducing an Activity Instance Model to the core Process Engine

(this post was originally part of the 7.0.0-alpha6 release blog post but later extracted into an own post). In 7.0.0-alpha6 we introduced the concept of activity instances and the activity instance tree to the core process engine. This post explains the motivation and gives some insight into the internal implementation. Why do we need an Activity Instance Tree? The activity instance tree contains a node for each activity that is currently active in the process instance. Some activity instances are scopes (such as Embedded Sub processes). Such scope activity instance may have child activity instances: So far so good. But is that not the execution tree provided by the process engine? To some extent yes, but not in  all cases. There are…

PHP SDK for camunda BPM: new Incubation Project started

If you want to do BPM / Workflow and BPMN 2.0 in PHP then we have good news for you: as part of our camunda BPM polyglot initiative we started a new incubation project which aims at providing a PHP SDK for camunda BPM. This SDK will facilitate the development of PHP-based applications that use the camunda BPM middleware services. The project will provide a client library which authenticates against the REST Api and provide PHP developers with a native API for interacting with the process engine: While the camunda BPM project stays focused on Java as primary programming language, we believe that it is important to support developers that use other programming languages and give them access to the BPMN 2.0…

Added message correlation to REST API. Support for shared process engine in IBM Websphere distribution (enterprise customers only). Read the full release notes in Jira.

The API is pretty straight forward, just execute a POST to the /messageresource. Example: {"messageName" : "aMessage", "businessKey" : "aBusinessKey", "correlationKeys" : { "aVariable" : "aValue" }, "processVariables" : { "aVariable" : "aNewValue", "anotherVariable"…

Camunda BPM incubation space launched with contribution by plexiti

I am happy to announce the official launch of the Camunda BPM incubation space with the first large community contribution by plexiti. View it on GitHub: github.com/camunda/camunda-bpm-fluent-testing The goal of the Camunda BPM incubation space is to promote the development of interesting new projects and ideas around BPM, BPMN and process engines. Due to the productization and stabilization focus in the camunda BPM core platform, we decided to separate out these experimental projects from the core platform. The core BPM platform is stable and maintained and can be found in the GitHub repository camunda-bpm-platform. This is also the base for the supported (commercial) camunda BPM platform product. The camunda-bpm-incubation repository contains a list of incubation projects which may be located in that…
