I've been using a package called org-brain that is using, I'm all but
certain, the org-id-locations file as its database to store graph-like
relationships between org files and org headings. org-brain is a sort of
graph database which adds a PROPERTIES drawer with just the ID field with a
UUID to an org file, as well as to the org headings in each file. So I
opened this 127k file residing in my .emacs.d directory and apparently
whatever is in my org directory and has a PROPERTIES drawer with ID field
winds up in .org-id-locations represented as plists in one big list, one
for each file that has one or more drawers. But you knowledgeable people
here know all this already. However, it surprised me since such a format as
this

(...("~/Dropbox/org/orgb_fassungen/FassungenDesc.org"
"1ba78dfc-d6c3-46c5-827d-37db94fa9053"
"6809202d-9a4c-4ed0-87fb-798676f448fe"
"f2149157-6ba1-4e24-81c3-4e070fcc5de8"
"5b7c2d9a-2df8-450a-a0c8-9d3b8e703044"
"f3031b9f-3708-493d-9546-f489835c9f17")
("~/Dropbox/org/orgb_fassungen/Fassungen.org"
"e9b683af-90b1-4ece-9afd-18dc28a9fab2")...)

where, e.g., inside the file FassungenDesc.org there are many org headings,
each with a PROPERTIES/ID drawer -- and they're all associated
to FassungenDesc.org with that simple list. So I'm asking if this is a good
design for a really big graph database? I'd like to start using org files
and their containing headings as vertices. But I'm guessing this is not
really all that scalable, not really intended for such a big thing. I saw
another emacs graph database (https://github.com/toshism/netz) that uses
h.el hash to store graph vertices and edges. So again, is this org-brain
approach DOA for anything big? I plan on having potentially hundreds of org
files with very many heading entries each (over a thousand perhaps per
file) representing vertices. What would be a better way of databasing org
files and headings? The PROPERTIES/ID drawer idea is fine, but not throwing
it all in .org-id-locations, right?

Ancillary: If I move or delete .org-id-locations, Emacs will rebuild it,
right? What is the idea behind having such a file structured this way --
other than a simple database? What else uses it?
