Workflow: New, Clean, Updated and UI on boost with JQuery 1.4
(Feb 15, 2010 20:23)
Discovering the already 1-month old super fast awesome JQuery 1.4, (what’s new?) we have integrated it seamlessly in our current user task list, and it turns out we only gained speed and reduced the number of bugs. Kudos to the developers. That was the sweetest upgrade ever. Not a single glitch. To celebrate, realized it [...]

SOAP UI, Regression Testing of Human based processes, using Groovy scripts or SOAP UI Steps
(Dec 01, 2009 11:21)
We have been using SOAP UI for regression and load testing of workflow. SOAP UI can be downloaded for free from the soapui.org website. Our story today is to test the absence request, which is basically a five step human workflow: init process from a human task create an activity task, complete the activity task, [...]

Update Human Task Metadata Implemented: Priority and other friends
(Nov 16, 2009 08:47)
A well needed addition to task management is now the possibility to edit metadata for an activity task. Say you look at your task list: And you feel you want to change the priority for this task. You would just have to click on the “Edit Task” button: That would trigger the jQuery-based dialog to [...]

Intalio
Tempo is a set of runtime components that support human workflow within an service-oriented architecture (SOA). Our main goal is to provide a complete and extensible workflow solution with a bias towards interoperable technologies (BPEL, BPEL4People, XForms, REST, and web services) as a default implementation.

| Web-based User Interface for Tempo |
The User Interface as a portlet(here embedded in liferay) |
The task manager process, responsible for handling task in tempo. This is running as a process. |
BPEL4People is a specification authored by BEA, IBM, Oracle, SAP and other companies that defines BPEL extensions for human workflow functionality. Tempo follows this architecture to provide all the workflow functions defined in BPEL4People. At this time, Tempo does not rely on any BPEL extensions and uses fully interoperable WSDL and REST interfaces as its core APIs. Over time, we intend to implement the full BPEL4People specification.
The BPEL4People specification can be found here.
The WS-BPEL specification can be found here
Tempo offers the following features:
- Extensible task object model
- Task List web-based user interface for users to manage their tasks (accept, complete, cancel, reassign, etc.)
- Security framework for role-based access control (RBAC) and single sign-on (SSO)
- Customizable set of BPEL processes to define workflow behavior (task assignment, escalation, etc.)
- Deployment Service to deploy task definitions, forms, etc.
- Attachments support
- Web-service and REST-based interfaces that allow integration with practically any language and web/user interface technology.
Technology integrations:
- Native XForms integration based on the Orbeon XForms engine.
- LDAP Directory integration for user authentication and role-based authorization
- Task data persistence in relational database (via JDBC)
- Storage of attachments in relational database (via JDBC)
- Task list user-interface implemented with Spring MVC and JSP/JSTL
Note that Tempo only provides runtime components; we recommend using design tools such as Intalio's Designer or the Eclipse BPEL Designer to develop your processes and forms.
Tempo is designed for software developers and architects familiar with Java, XML, BPEL, REST, web services and, to a lesser extent, XForms.
