"Oslo": The Language

The "Oslo" language, at the heart of the Oslo modeling platform, allows developers to quickly and efficiently express domain models that power declarative systems, such as Windows Workflow Foundation and "Dublin." In this session, we'll get you started writing models for your own domains by introducing you to key features of the language, including its type system, instance construction, and query. You'll learn to author content for the Oslo repository and understand how to programmatically construct and process the content to target your own specific runtime environment.

Don Box is so right. If i dont have text, i dont care about boxes and arrows. I dont have to hate boxes and arrwos but i have to have text.

I cant wait to see the Enitity Framework m-language. IMHO this could be the best thing in years.

The examples from this video does not seem to work with the (October 2008 CTP) of the "Oslo" SDK  Version 1.0.0925.0 currently avaiable at msdn.microsoft

The spouses 'SpouseA' and 'SpouseB' in the 'Marriage' type does not get the correct data type which should be
the identity key 'Name' nvarchar(28) from the table 'People' .
Instead it get's a nvarchar(max) so the constraints for the 'Marriages' table does not comply.

I get the following errors when running mx.exe

Installing Image: Contacts;Version=1.0;Locale=neutral...
Column 'Contacts.People.Name' is not the same length or scale as referencing col
umn 'Marriages.SpouseA' in foreign key 'FK_Marriages_SpouseA_Contacts_People'. C
olumns participating in a foreign key relationship must be defined with the same
 length and scale.
Could not create constraint. See previous errors.
