Review if/how the algo has been implemented in 'orxyx-editor'

[tbouffard]

The paper mentions on p 398 the orxyx-editor as a bpmn vendor for integration of the algorithm

The next step is integrating the algorithm with the afore-
mentioned Oryx Editor in cooperation with the Hasso-
Plattner-Institut. This will allow everyone to evaluate the
algorithm or download its source code as part of the Oryx
source.

Original googlecode home: https://code.google.com/archive/p/oryx-editor/
This project served as base for the Signavio implementation

The new home for the source code is https://github.com/tiku01/oryx-editor (as of 2020-04-15, latest commit occurred on July 2015)
Let's review if the algorithm has been finally implemented there

There is an implementation of the algorithm here:
https://github.com/tiku01/oryx-editor/tree/master/editor/server/src/de/hpi/layouting

It looks like there is also an "edge layouter" checking that out

Start of the algo:
https://github.com/tiku01/oryx-editor/blob/73f0080cb90798fdba35ab3768ef3303123a4fdd/editor/server/src/org/oryxeditor/server/BPMNLayouterServlet.java#L109
see also de.unihannover.se.infocup2008.bpmn.layouter.EdgeLayouter

1: layout subprocesses
2: layout processes
3: put boundary events
4: layout edges

This produce a Layouting Diagram that have LayoutingElement that have a geometry ( width + height + x pos + y pos )
There is a concept of docker to know where to connect edges and boundaries and i guess for waypoints
