Author Topic: Common Warehouse Metamodel (Read 9627 times)

Hello everybody

I came across OMG's Common Warehouse Metamodel available as XMI 1.1.

I tried to import in EA as a package and I got an error about a missing root package. Then I tried to import it as a profile and I had a parsing error.

Any suggestions? What am I doing wrong?

Regards

Ernesto

Maybe you post the link so someone else can try.

Importing a profile won't work since EA's profile definition needs a propriate file format (it's not XMI).

link : http://www.omg.org/cgi-bin/doc?ad/02-05-01

i think the problem is here : <XMI.exporter>Unisys.JCR.1</XMI.exporter>

apparently the xmi is not the same everywhere ... not sure whether there is a way to import such a file ...

anyway - i remember i once had my colleague import the model into Rose and it didn't help me understand it :-).

Sorry for omitting the link ( Moses, thank you for providing it ).

I managed, however, to download the Rose (yuk!) mdl files also from OMG and as Moses said it doesn't help understand CWM. Better refer to the specification itself.

What I'm basically trying to do is to document our data warehouse and BI data, processes, ETL, etc, and I thought the CWM could be a good framework to do it.

The way I'm doing it is by organising whatever I find into the Analysis, Foundation, Resources and Management packages and show interdependencies between them.

I would like to hear from anyone that has tried to do the same.

Hi Ernesto,

I think the problem is: CWM use his own dtd file (not UML.dtd or UML_EA.dtd)

Hi Oliver

I thought CWM would have a similar UML DTD since both specifications come from the same MOF. Anyway, thanks for trying.

Regards

Ernesto

Hi Ernesto,

1. CWM use a dtd - file called 02-05-02.dtd

2. The Import/Export Feature currently don't have MOF-Support. You can only import UML-Models (with UML_EA.dtd)

Oliver :-/

Oh, I see. Now it makes sense. Thanks, Oliver.

Hi Ernesto,

take a look at the new EA 6.0 (beta). It works

It works indeed, Oliver. Thanks!

Ernesto, Oliver

I am trying to use EA 6.0 to model an OLAP solution using the CWM stuff - can you let me know how you imported the CWM stuff into EA, please

ErnestoC · « **Reply #11 on:** January 18, 2006, 04:19:30 am »

Certainly:

1) Make sure you have EA 6.0

2) Download the common warehouse metamodel from OMG's website (http://www.omg.org/cgi-bin/doc?ad/02-05-01)

3) Open your EA project (or create a new one)

4) Highlight the package where you want the metamodel imported.

5) Click on Project -> Import/Export -> Import package from XMI.

6) In the dialogue browse for the filename downladed in step 2.

7) Click on Import and you're done.

Thanks Ernesto. That has worked fine.
