A preservation copy of the data from GloPAD expressed as a compressed, Postgres database dump file called "glopad3.sql.gz" To work with this file, researchers will need to download, reimport/reestablish the file as a working Postgres database. After this, the record metadata can be explored natively. The database was built without foreign keys in the tables. During preservation, Cornell University Library Preservation Services refined a python script that injects the foreign keys into the tables of the database. The code that creates the foreign keys is called create_fk.py and the code to inject them is called add_foreign_keys.sql. The resulting improved database (dumped and compressed) is called glopad3_fk.sql.zip. All three files are also offered in addition to the original database export in case the researcher finds these more suitable for the research need. The full description and rationale for the preservation strategy is provided in the file "Preservation_of_GloPAD.docx".
