BSG/Helveticat conflict resolver
The BSG and Helveticat use the GND as a unique identifier. They check every day if the GND changed some numbers and may update those. Because of that we can't really relay on this identifier. It may change all the time and we don't know about that.
-
Write a conflict resolver for BSG/Helveticat. We need to solve conflicts if they appear. -
Write an Updater for all current identifier. We want to update them to the newest identifier -
Update importer. We need to clean old data from metagrid -
Write some tests -
Check again. It looks, like we did some mess up between gnd and bsg
