How to transform TAGs for attributes

[osmid]

Hello,
   we are using TAGs for class attributes in PIM model.

We want to use MDA transformation from PIM to PSM in Java. I do not know how to change MDA transformation to copy TAGs for attributes.
I only know how to create one new tag (like tags for operations), but it is not what we need.

Could you help me, please? Thank you.

Regards

For each of the known tags, create a tag.
