This is a bug having to do with unaries in the orginal ORM diagram, and I will be reporting it as such.
Until then, here is why the OIAL to DCIL bombs out.
#error Exception occurred while executing transform 'OIALtoDCIL'. The existing contents of 'ORMModel1.DCIL.xml' will not be modified.
// System.ArgumentNullException
// Value cannot be ...

I have a bunch of these errors on the MyModel.CoRef.orm diagram when I am trying to generate a build.
These errors are on the generated CoRef.orm diagram. For example,
'' At least one reading is required for fact type 'OrganizationOrganization_isnonprofit' in model ''. ORMModel1.CoRef.orm ''
OK... I am confused. What more can I give it ...

Kevin- Thanks again for the fast reply... I was able to clean up a lot of errors by naming roles. I stumbled into another problem, but will start a new thread.
Brian- Thanks for the heads up on the DDL... we might have some code to assist on clean up stuff, but that's not for today.

Hi,
Ring constraints have been problematic right along. As Kevin mentioned, naming roles is an elixir for a number of referencing problems. Actually, the more things you name, and name well, the better. When the tool does a better job of this, you might need to go back and redo some stuff - but it is CTP after all. Also, be aware that DDL ...

Sorry about the issues you've been running into.
The solution for this one is relatively simply: give one or both of the roles a role name.
Our current behavior when a role doesn't have a role name specified is to use the name of the object type that plays that role instead. This obviously has the drawback of causing duplicate names when you ...

Interesting. I have a External ValueType that is an independent and has three value constraints. Why does that work and the other two do not??
Next problem: There is a duplicate key sequence 'Person'
roleSequenceUniquenessConstraint
name=''PersonIsRelatedToPerson''
<oil:roleSequence>
<oil:typeRef ...

in the middle of troubleshooting these problems... decided to capture work flow for ya... possible requirements/UI features...
Error Message tells me what row is incorrect in the OIAL.XML file. I dbl click and I find the row.
A couple of rows above that I see the singleRoleUniquenessConstraint name...
Now I want to find the constraint in ...

Hi Jason,
The architects on the NORMA tool team have very strong OO programming backgrounds, but obviously know ORM and database design issues as well.
Clifford Heath (the fellow that started the Yahoo Group: Information_Modeling), is working on a Ruby on Rails framework using the fact based nature of ORM for application development. He ...

Trying to clean up a substantial model and running into errors on the OIAL.xml file. Did not get these errors when we compiled using Jan CTP. Now using March CTP against same model.
(Aside note for documentation: Need some verbage that says if end product *.sql from build process fails, start looking at why by first clicking on the OIAL file ...

Brian-
You're right there appears to be a lot that can be done with this tool already, but at some point there needs to be a production tool of some sorts. We switched over from Visio EA to NORMA.
I am a ORM fan as well due to the influence of Prof. Everest at the University of Minnesota.
We have similar interests as I am fascinated by ...
