[EP-tech] FW: REF2014 Plug-in installation failed because of duplicate fields

Dear All,

Sorry to bother again. I was trying to install REF2014 plug-in on our demo server which runs 3.3.8. However, when I tried to upgrade the database schema. I got a system error complaining about a duplicate field "user.dob" as followed:

---------------- EPrints System Error ----------------------------
Duplicate field name encountered: user.dob

I have checked my database and indeed there exists a field "dob" in the "user" table already because of R4R plug-in.

After I compared the "zz_r4r.pl" file (R4R plug-in) and "zz_ref.pl" (REF2014 plug-in), I can see several duplicate fields defined (not only the "dob" field):

I wonder how I can resolve this issue while keeping the R4R plug-in which I found is useful. Shall I simply comment out the duplicate field definitions in the "zz_ref.pl" file and continue? If so, would it influence the using of REF2014 plug-in? Thank you so much for the kind help in advance!

Best Wishes,
