Short recap on OFM Summer Camps 2014

Last week the Oracle Fusion Middleware summer camps took place in Lisbon. More than 100 participants attended the event, learning much new stuff about new features and enhancements, arriving with the recently available FMW 12c release. In four parallel tracks the highlights of the new major release were presented to the attendees; hands-on labs allows to […]

Finding differences in two Open-Office-Writer documents

If you write documents and get feedback from different persons on different versions it is a great pain to merge the documents and changes together. Microsoft Word has a functionality that works quite well. But the function to compare documents in Open Office Writer has  never work for me the way I expected. Fortunately OO […]

camunda BPM – Mocking subprocesses with BPMN Model API

A common way to call a reusable subprocess is to use a call activity in the BPMN 2.0 model. By using a call activity it is only necessary to add the process key of the subprocess to call and the version of it to the call activity properties. Thus, the modeling can be continued. Apart from this it […]

IoT prototype – low-level thoughts about camunda BPM and Drools Expert (part 6)

As already mentioned in the second part of this series, building systems of this type consists of several components. In this part we describe the integration of a BPMN 2.0 capable workflow management system and a business rule engine in our IoT prototype. Why do we need such things Currently we live in times of a knowledge society […]

IoT prototype – Retrospective. What did we learn? What did we miss? (part 5)

Okay so controlling our lights now works automatically based on entering and leaving the building, thats great! But what did we learn from all this? What do we believe can be transferred to a general concept found in (almost) all possible IoT projects?   What did we learn? Communication takes more than one way Meaning, […]

IoT prototype – low-level thoughts about the 433mhz communication (part 4)

This prototype started off as a personal project. So it’s not a big surprise why the 433mhz plugs were chosen as a first tech. They are in every household and I wanted to retrofit what was already there to become a bit smarter. Being able to group, manage and remotely control these plugs is an […]

IoT prototype – low level thoughts on Oracle CEP Embedded (part 3)

In our prototype we used an Oracle CEP Embedded application running on a separate Raspberry Pi to scan the network for arriving / leaving devices and link them to our users. We could have left this logic in our Spring server and have it running in our service layer but we wanted to learn more about […]

IoT prototype – an architectural overview (part 2)

With our prototype we had a few goals: learn about the technologies that are involved in the IoT space Follow a good architectural principle get the attention (and trigger their curiosity) of visitors at different events Of course there were also the functional requirements of being able to effectively know when a user is present or […]

OMG released formal version of CMMN 1.0

In May 2014 the OMG released version 1.0 of the Case Management Model and Notation (CMMN). You can access the documents associated with it under http://www.omg.org/spec/CMMN/1.0/. Great to see that the specification also includes the “CMMN – Claims Management Example” (page 78) from our “ACM in Practice” poster.
