Alternatives to XMI format

2009-11-11T00:22:19Z

Are there any alternatives to the XMI format, preferably ones with
existing transforms from XMI, that represents a SysML model in a
manner that more closely resembles the structure of SysML?

I'd like to extract bits and pieces of SysML models for usage in other
tools, and I want it to be easy so that it can be done in close to an

Hello Frank,

I think it depends on the tool you're using to model SysML. I'm using
Artisan Studio Uno (it's free) and here when you create an operation you can
add parameters. For each parameter you can assign the type of the parameter
which can be a block (Wheel for you). When you do a CallOperationAction (I

RE: [SysML Forum] Interfaces usage

if i understand correctly, the port cannot "provide" a service, rather it defines a point of interaction with the block.
the block must provide the service.
the block should inheret the same interface that is "provided" by the port, and should either include an implementation of the service, or an allocation to a sub-block.

Interfaces usage

2009-11-09T14:55:34Z

Hello,

I have tried to understand the use of Interfaces on standard ports and I
even use them to provide or require operations (as in Interfaces we define
the operations). What I didn’t understand is why in an Sequence Diagram it
is not possible to use these operations in order to describe the system’s

Re: Target of CallOperationAction

Firstly, thanks for u answers. i try it, but i didn't find how to
choose a part of my system as parameter in SysML.the only things that
is available is Enumeration as Instance value and user-defined value.
i fear that isn't possible.

How to select the reigthFrontWheel part already design in my model?

i would use a single port on A and a single port on B.
However, for the provided and required interfaces i would use the interfaces of ports p_B1 and p_B2 as superclasses for the interface of p_B (iow i_B1 and i_B2 are superclasses of i_B). the same for ports p_A, p_A1, p_A2\i_A, i_A1 and i_A2.

RE: [SysML Forum] Target of CallOperationAction

Hello,

I think you can do that by adding a parameter to your operation with the
wheel type. When you call your operation you give the rigthFrontWheel part
value to your parameter.

Ralph
Many thanks for your help here. Hopefully you will see my other post where I
have submitted a worked example of this in MagicDraw, and a write up also.
I would have liked, and still would like, to try this with Artisan also.
Unfortunately the free Uno edition is not really supported, so I couldn¹t

Instances - an example to talk about

2009-11-06T14:50:58Z

Hi all
I am, for my night job, working on a dissertation aimed at creating a
Network Design Modelling Language (NDML). Some of you have seen my earlier
posts about instances, and no doubt enjoyed the related discussions :-)
I felt that it would be useful to anchor such discussions with an "real
world" example, so I have created one using MagicDraw and attached it, and a

Hello,
I am a little bit new on sysML, I hope you'll forgive me to query on a
basic question.

I try to modelize a system, allocated on several centres. Centre A and
centre B.
Centre A is divided into 2 parts : Part A1 and Part A2
Centre B is divided into 2 parts : Part B1 and Part B2

On a logical point of view, A1 communicates with B1 and A2

Target of CallOperationAction

Hi,

i modelled a procedure of my system through an activity diagram. i use
a callAperationAction and as target, i want to chose an instance of
block of my model. i explain:
Example: my system is a car with four wheels ( rigthFrontWheel,
rigthBackWheel, leftbackwheel, leftFrontWheel), to model this, i draw

Block Definition Diagram query

2009-10-27T23:38:19Z

Hi,
In my Block Definition Diagram, the input parameters and the return
type of a Operation must be XML. The input parameters and the return
type may have different XML structure (i.e they use different XML
schema).

What is the best way to model this ? If I use primitive type "String"
for input and return type this doesn't capture the structure of the

You can use a SysML Use Case diagram and use the actor element with

to model stakeholder's in SysML.

Laurent,

If you didn't understand my previous comments or the SysML FAQ regarding
this topic, I recommend that you carefully read Russell Peak's 22
October response to this thread, in which he recognizes "the need to
support instances explicitly" and notes that "the OMG SysML Revision
