The next #Ontology Summit session on Wednesday 29 April 2026 will feature

Will Sobel

who will present

The Evolution of an Industrial Standard: From Paper to Ontology

As usual, all summit sessions are zoom sessions on Wednesdays at Noon US/Canada Eastern Time, and each session lasts one hour. The summit is open to the public and no registration is necessary. All summit sessions are recorded and are available on the summit web pages and on the Ontology Summit YouTube channel.

@macberg Maybe give Gaphor a try?

(I pitch it as "Notepad for models" for rapidly making a design and haven't used it for complex systems.)

Modeling for Everyone

Gaphor is a UML, SysML, RAAML, and C4 modeling application written in Python. It is designed to be easy to use, while still being powerful. Gaphor implements a fully-compliant UML 2 data model, so it is much more than a picture drawing tool. You can use Gaphor to quickly visualize different aspects of a system as well as create complete, highly complex models.

while performing by duties,
creating architecture, modelling,
it became very clear,
why one need to use a formal language,
you find inconsistency,
why,
because you benefit from experience that build the formal language, countless hours and knowledge just ready to use

#MBSE #SysML

of course you need a tool as well

@ragman I mostly model in SysML v1, but it overlaps a lot with UML. So I start with PlantUML a lot when prototyping or for an everything-as-code approach.

SysML v2 has textual representation, though it reads a bit more like code then a markup language like PlantUML.

Does it make sense to use constraint blocks in #SysML parametric diagrams to show error probabilities? How would you connect such an error probability to a block that causes errors at the specified rate?

Andreas Dec 28

How would you model error cases in #SysML ? Most SW and HW parts that exist in a complex system can cause errors.
My spontenous idea would be to either not model these at all or to show these as regular control flows in e.g. activity diagrams. Is there a nicer way to do this?

Andreas Dec 28

How would you model system parts in #SysML that you do not fully understand and that come with more features than you need? E.g. you integrate an "Android 14" software system as guest onto a hypervisor partition and update this every couple of months.
My spontaneous idea would be to model it as a black box, allocate my requirements (Expectations) onto it and require test cases to ensure that needed functions are working...?
