Design
Goals
• 1.
Easy
access
 Zero-­‐installation,
a
process
model
“just
a
bookmark
away”
• 2.
Full
BPMN
support
 All
language
constructs
and
attributes
• 3.
Extensibility
 New
languages,
new
functionality
• 4.
Support
for
open
standards
/
interoperability
 XPDL,
RDF,
BPEL

5. Oryx

6. Oryx
History
• 2005
 Idea:
create
own
process
modeling
tool
suite
at
BPT
group
 First
version:
GEF-­‐/eclipse-­‐based
BPMN
editor
• 2006
 Bachelor
project
starts
developing
Oryx
• 2007
 Oryx
released
as
open
source
 Major
interest
from
industry
and
academia
 First
external
plugin
from
Stuttgart
(BPMN
2
BPEL)
• 2008
 Continuous
improvements
 More
HPI
plugins
(EPC,
layouting,
analysis,
…)
 More
external
plugins
from
Stuttgart,
Australia,
Estonia,
…
