Cache table "isil2opac_hbzid"

[dr0i]

Don't make a URL lookup to get the concordance every time an item is shown. Load thie concordance from a gitsubmodule table and cache it as HashMap.

Follows #1893.

Loading the file in Global and setting a static field on the Lobid controller seems more complicated than needed. Play has a built-in cache which I think would make sense to use here. It's already used elsewhere in the controller, see:

lobid-resources/web/app/controllers/resources/Lobid.java

Line 148 in 880219b

return Cache.getOrElse("res.label." + id, getLabel, Application.ONE_DAY);

I don't think this makes sense as it would invoke the loading of the file hundreds of time.
I think play's cache makes sense for caching websites, not files. Or have I missed something?

[fsteeg]

Well it would load the file only once, and after that use the cached version. It's not about a browser cache it that's what you are thinking of. It's a server side cache.

@dr0i @fsteeg I am not sure I we should proceed with this PR because we are about to add this info to the record metadata: #1888 and #1906

[dr0i]

Definitely not :) . See #1868.
Closing.
