Create Id:s on all types of objects

I have a long process to walk through a couple weeks....

I will create an text export script and an text import script.

I am new beginner I have been written many scripts in vba, for (Excel and Word).

and just simply once in Indesign..

What do you think about this idea?

Create an list of all objects in a document (the ID:s)

then try to make a function that export the  text and ID into a line in a textfile.

then when I create an import script if "ID=1" exists then take the "ID=1" in the textfile and replace.

have you got any suggestions?

Thank you in advance.

Best regards

Daniel.
