With eomodel you are refering to
https://en.wikipedia.org/wiki/Enterprise_Objects_Framework ?

Since Umbrello does not support direct import of eomodels, it is
necessary to find a third-party application to convert the model to a
supported import file format. Umbrello is currently able to import
entity relational models from mysql and postgresql statements.

yes, importing such a file requires the creation of an importer plug-in
consisting of a file parser [2] and a binding class to map the parsed
instructions into UML objects and widgets models.

If interested, such a feature could be implemented within the scope of
GSOC 2019 (https://summerofcode.withgoogle.com/). We are still looking
for students.

To track this feature request for Umbrello, an associated feature
request should be opened in the Umbrello Bug Tracker at
https://bugs.kde.org/enter_bug.cgi?product=umbrello.
