Bridge 7 The OData Importer imports OData Version 4.0 definitions encoded in CSDL (.edmx) and creates UML model elements corresponding to the definitions.
The CSDL file of your OData service can be retrieved from this URL: http://<servicehost>/<servicepath>/$metadata.
Limitations
-
The OData Importer supports OData files of version 4.0 for entity and service description.
-
Concerning older OData versions, we mostly support 3.0 for entity import but cannot import service descriptions.
Service Import Limitations
The OData Importer has the following limitations concerning import of service descriptions:
-
You cannot use $count to get the number of records returned by a request. This would return an integer in the response body and that is not supported.
-
You cannot use Open Type features to support dynamic properties.
-
You cannot request an individual property of a complex structure using
<entity name>('<entity ID')/<individual property name>. -
You cannot group multiple requests using the batch feature of OData.

On importing an OData entities description, the importer will generate a package structure from the OData definitions. The entities are generated to a package Entities, the types to a package Types. For each entity and type, a corresponding collection type is created.
