In ALMA all zdb records loose their hbzId (aka HT Nummer). To keep at least their old record Id as deprecatedUri . I created a mapping file from the last aleph transformation and map the zdbId to the old hbzId. With this I create the deprecatedUri element.

I think commiting a 44MB file is not good ... idk. idli. Or am I to old to consider this too much data?
Seems ok, as even the tests are ok with it . So RAM is enough (idk exactly but I think this map is loaded at whole into the memory). |

Would be nice if those deprecated IDs could also be searched in the union catalogue ( |
It's "only" 12 MB compressed: alma-hbz-to-zdb.tsv.gz |
|
I created a gz file from my tsv and added the old hbzId to the zdb titles. Perhaps also we could reuse the file from Jens/Verbund. |
Great, thanks! |

The lookup holds 2.000.000 + key value pairs. I hope this is not to heavy on the performance.
