Alternatives to XMI format
|
| |
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... more »

Interfaces usage
|
| |
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... more »

Instances - an example to talk about
|
| |
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... more »

Ports and (Internal) block diagrams
|
| |
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... more »

Block Definition Diagram query
|
| |
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... more »

Lack of complete Instance semantics in SysML
|
| |
...Actually, it's more ironic than odd. During the time when the two SysML submission teams were actively competing Instance syntax/semantics was a key design issue on which they seemed to agree at a high level. Indeed, the SysML Partners planned to incorporate Instance syntax/semantics in the next (beta) version of their specification.... more »
