;;; Commentary:
;; A cache of metadata about the structure of all your Org files - headings,
;; links and so on.
;; Builds quickly, so that there is no need to persist data
;; across sessions.
;; Provides two independent APIs:
;; - Emacs Lisp: regularly named accessors such as `org-mem-entry-olpath',
;; `org-mem-link-pos', `org-mem-all-id-nodes' etc
;; - SQL: an in-memory SQLite database that can be queried like
;; (emacsql (org-mem-roamy-db) [:select * :from links :limit 10])
