Right now I am using org-noter to annotate PDFs, mostly by calling org-noter-insert-precise-note (which generates an org-heading with an ID). Currently org-roam is capturing each annotation as an individual node, which is leading to an unmanageable number of nodes in my database. I am aware of `org-roam-db-node-include-function` from the manual, but am not sure how/whether I can use it to exclude org-noter notes from being cached as nodes in my database. Thanks! ---

@mandelbot As far as I can see, `org-noter` itself does not add an ID to notes by with `org-noter-insert-precise-note`. (My PDF notes have no IDs). I believe you have additional packages, probably `org-noter-pdftools`, which has this customizing variable: ```auto (defcustom org-noter-pdftools-use-org-id t "When non-nil, an org-id is generated for each heading for linking with PDF annotations and record entry parents." :group 'org-noter :type 'boolean) ``` If you don’t need IDs, I guess you can try turning it off and see what happens. Alternatively, [Section 6.1 of the Org-roam manual](https://www.orgroam.com/manual.html#What-to-cache) mentions `ROAM_EXCLUDE` so you should be able to add an additional property either manually or automatically via some custom function. ```auto * Foo :PROPERTIES :ID: foo :ROAM_EXCLUDE: t :END: ``` Edit: Option 3 would be to use `org-roam-db-node-include-function`. The section referenced above contains this sample code: ```auto (setq org-roam-db-node-include-function (lambda () (not (member "ATTACH" (org-get-tags))))) ``` As your Org-noter headings contain `NOTER_PAGE` property, I think you can add something like this. ```auto (setq org-roam-db-node-include-function (lambda () (not (cdr (assoc "NOTER_PAGE" (org-entry-properties))))))) ``` I don’t have time to test this idea; perhaps someone can jump in. ---

Thanks @nobiot. I tried the first two options by myself and they worked. However, the option 3 is what I was looking for. I think in your code there is some mismatches for parentheses, and I used the following in my init.el: ```auto (setq org-roam-db-node-include-function (lambda () (not (cdr (assoc "NOTER_PAGE" (org-entry-properties)))))) ``` ---

@gnohz Thank you! So your version works, right? ---

Yes. ---

You are right this was an org-noter-pdftools function, and option 3 is also exactly what I was looking for! ---

Option 3 worked for me. Thank you people! I initially though it wasn’t working as a solution because I could still see the org-noter-pdf headings as org nodes. However after I ran org-roam-db-clear-all and then org-roam-db-sync they were removed.
