General Board / Re: 4+1 architecture
« on: March 21, 2011, 06:38:33 pm »
Hi Rob,

I never used the 4+1 model in a given project but did some investigations a while ago for a prospect client and it doesn't seem far from what I'm doing in EA currently i.e. requirements model, analysis model (use case, ...), design model, and architecture model.
The core of my EA project is traceability e.g. from requirements to use cases, by instanciating an object from a class, etc.

In the 4+1 model, if asked to apply this, I would create the following using EA when suitable EA default models :
- a use case model (the "+1" model)
- a domain/class model = logical view
- a business process model = process view, for my activity diags
- a component model = the dev view (component diagrams)
- a deployment model = physical view (apply components to nodes)

Of course this is just the EA project template to start with. The processes involved in running your project are to be defined and followed in a manner that makes use of your EA project structure, adapting it when necessary. However the project should be lead by the use cases and its scenarios

General Board / 4+1 architectural view EA project ?
« on: November 15, 2010, 11:18:46 pm »

I'm likely to use the 4+1 architectural view project (for any information, check out Wikipedia

EA has this listed in its list of project samples but it only generates empty project (with Logical, Process view, etc.)
Has anyone used this approach and could share a sample project ?

Thanks!  :)

Will do


General Board / Re: SysML Simulation : output of 1.#QNB  value
« on: October 08, 2010, 06:59:13 pm »
The engine running for the SysML simulation seems unstable.
When running the simulation from my parametric diagram, having updated the values and script, I'm currently getting an SScripter.exe error ("memory cannot be read")

Any idea?

General Board / SysML Simulation : output of 1.#QNB  value
« on: October 08, 2010, 03:28:00 am »

I'm trying out SysML parametric diagram and EA simulation module for a customer.
I defined the script for my constraint block before creating my parametric diagram.
When I instantiated my constraint block as a constraint property, put my parameters and entered values in the simulation module, it worked ok

I then instantiated my constraint block again to create a second constraint property - for some odd reasons, I'm now getting values with 1.#QNB

any idea what's going on?

General Board / Re: UML Profile for SCRUM ?
« on: March 09, 2010, 09:00:57 pm »

There is an approach in terms of generating sufficient (not too much) models/docs for SCRUM, introducing the concept of the following:
  • Spec user stories (e.g. scenarios under use cases)
  • Features
  • Tasks

Basically all is available under EA to do this, but a UML profile would be useful especially if it's been tried and tested
Hence, if a UML profile and possible base project structure is available; it'd be useful.


General Board / UML Profile for SCRUM ?
« on: March 09, 2010, 06:55:23 pm »

I'm looking at using EA with an agile project involving SCRUM.
Does anyone know if a UML profile is available somewhere to support the SCRUM framework, e.g. product backlog, user stories, features, tasks...


General Board / Tagged values and CSV export/import
« on: March 17, 2010, 01:44:02 am »

I created some tagged values in a number of packages that I'd like to include in my CSV file when running a CSV export.

EA doesn't support this and I was wondering if it could be added?
e.g. export Name, ..., Tagged value 1, Tagged value 2, ..., Tagged value n


General Board / UML Profile and Icons
« on: March 16, 2010, 11:55:02 pm »

I created a UML profile to define a stereotype for a Package and I'd like to specify an icon (so when I create a new element that has this stereotype in EA, it'll be displayed with a different icon).
Unfortunately Sparx only releases the XML files for existing UML profile on their resources page so I cannot see how it's been specified in the source EAP file.

I noticed in the SPEM UML profile (XML file) that the Stereotype tag has the following:

Can anyone indicate how I can specify this in the EAP file that generates the UML profile?


General Board / EA v8: Dynamic Visual Filtering ??
« on: March 11, 2010, 09:57:28 pm »

Can anyone let me know how to use Dynamic Visual Filtering, introduced in v8??
there's nothing in the EA help explaining how to make use of this.


General Board / Re: UML Metamodel as a project?
« on: February 17, 2010, 08:12:45 pm »
The only major issue I found from the OMG XMI is that it's missing multiplicities - am not sure why it's not included.

Hi Geert,

Thanks for posting the XMI - I managed importing the file you published in the Community site into a new EAP.

The only thing that remains doing is to create class diagrams to render the metamodel structure.

Hi Geert,

thanks for the info - do you remember where you found the OMG XMI?
If you still have it, do you mind giving the url?


General Board / UML Metamodel as a project?
« on: February 13, 2010, 12:41:49 am »

Is there a way to easily display and navigate through Class diagrams in EA the UML metamodel?

For instance showing the following classes and their associations: Classifier, Element, NameElement, PackageableElement, Relationship, DirectedRelationship, etc.

As this is built in EA, is there an easy way to render it?Or is there any EAP file that can be downloaded, giving visibility over the complete UML metamodel?


General Board / EA 7.5 slow (notes)
« on: January 05, 2010, 11:02:25 pm »

I recently upgraded EA from 7.1 to 7.5 (build 849).
The main issue I have so far is that EA is slower than usual, especially when entering some notes in a Class or other container.

I'm using Windows Vista and whilst I'm typing the description, the cursor changes to a busy mode and it takes some time for the text to be displayed on the screen.

any ideas?
