Provide "subjectOf" as BEACON ?

[dr0i]

Via email from S.H. from 15.04.24:

Bei der Gelegenheit möchte ich auch gleich noch eine BEACON-Datei anregen,
die ebenso themenbasiert (subjectOf) zum hbz-Verbundkatalog verlinkt. Für
diesen gibt es ja bisher nur die personen/organisationsbasierte
(contributor) BEACON https://lobid.org/download/beacons/hbzlod-pndbeacon.txt

Analogue to hbz/nwbib#646 : providing a subjectOf list as Beacon.
(This may generate too much work to do "by the way" as it would mean not only to iterate over 0.5M records but 26M.)

Maybe it is sufficient to query the list of interest by using the API like this:

subject.componentList.id:"https://d-nb.info/gnd/4066009-6" OR subject.componentList.id:"https://d-nb.info/gnd/4004744-1"

You can "OR" as many GND-subjects (or DDC etc) as you want (note that it may be necessary to POST instead of GET since the length of a URL has a restriction).

Get all the data like this:

curl --header "Accept-Encoding: gzip" 'http://lobid.org/resources/search?q=subject.componentList.id%3A%22https%3A%2F%2Fd-nb.info%2Fgnd%2F4066009-6%22+OR++subject.componentList.id%3A%22https%3A%2F%2Fd-nb.info%2Fgnd%2F4004744-1%22&format=jsonl' > architektur.jsonl.gz

(more API tricks e.g. in http://lobid.org/resources/api#bulk_downloads)
Then gunzip architektur.jsonl.gz.
Get all lobid/alma-IDs like this:
jq .almaMmsId architektur.jsonl

I will asked S.H. if this would be feasible.
