Export/import/backup data from Dspace repository

Those instruments can be useful for exchanging content between repositories. Scripts were tested on v6.3 . More info - https://wiki.lyrasis.org/display/DSDOC6x/AIP+Backup+and+Restore.

Export content - community or collection via AIP

/dspace/bin/dspace packager -u -d -a -t AIP -e admin@email.ua -i 12345678/1111 /home/dump_dspace/open.zip

where 12345678/1111 -- handle, community/collection URL 

/home/dump_dspace/open.zip -- dumped community/collection in zip archive

admin@email.ua -- admin repository email

Import content - community or collection via AIP

/dspace/bin/dspace packager -u -r -a -k -t AIP -e admin@email.ua -p 12345678/1111 -o skipIfParentMissing=true /home/dump_dspace/open.zip

When you are trying to replace content - will be a problem with community/collection permissions. All permissions will be on input user - admin@email.ua (only admin can read items). Those scripts can change permissions to disable admin@email.ua and allow to Anonymous read items, bitstream, license, bundle. After end of script work you have to run:

/dspace/bin/dspace cleanup -v
/dspace/bin/dspace index-discovery -b

where cleanup -v -- will delete all trash

index-discovery -b -- will update search index. After running this command - the count of items will not be zero

How to work with scripts

1. You have to install/update Python. It works with v3
2. Intall packet maneger - pip. For Ubuntu -- sudo apt install python3-pip
3. install dependencies - pip install psycopg2-binary
4. Edit file change_per_com.py. Find row 63 connection = psycopg2.connect and change all parameters in accordance to your Postgresql server connection.
5. Edit file change_per_com.py. Find row 18 where email=admin@admin.ua and change email according to admin email of destination repository
6. Run script python3 change_per_com.py
7. Enter community hande id

---

If you can't run the script on database server.

You have to change /etc/postgresql/9.6/main/pg_hba.conf by changing the last row according to:

host all dspace all trust

and then you can run it from your computer. This row changes access permissions to Dspace database.
