Thomas Bergstraesser asked me to forward this to you:


We have developed the Open Information Model (OIM) a set of over 200 types
that describe meta data in the application development, database design, and
data warehousing domain. Part of this model is a complete database schema
model for relational, multidimensional, and legacy models.

> The OIM is described completely in UML and can be mapped onto different
> implementation technologies. The interchange of meta data described by OIM
> uses XML and we generate DTDs directly from the UML model. The DTD
> provides the tags and structures to describe elements like schema, table,
> column as well as cross relationships to components or executables.
> 
> We have announced recently that we will move the OIM and its XML
> Interchange Format to the Meta Data Coalition. We are currently in the
> process of removing all vendor- specific information from the model in
> order to make it technology-independent and vendor-neutral. As its sounds
> this might be an ideal starting point for your efforts and provides you
> with the additional benefit that your schema can be stored in many
> existing repositories and displayed by over 60 modeling tools.
> 
> Our Web site http://www.microsoft.com/repository should provide you with
> all the necessary information including a downloadable version of our SDK.
> The SDK includes the UML model of the OIM, the DTD generator, and the DTDs
> for all the different parts of the OIM as well as the necessary
> import/export utilities. Note that this is all still focussed on the
> Microsoft Repository technology.
> 
> I hope this information is helpful for you.
