Re: Exploring properties

[John Kitchin]

org-ql (https://github.com/alphapapa/org-ql) is also quite good for this kind of thing.

Here is even a database like query to find the heading, and EMAIL property from all the files in a list returned by the function nb-org-files.

(org-ql-query
  :select '(cons (fifth (org-heading-components))
 (org-entry-get (point) "EMAIL"))
  :from (nb-org-files)
  :where '(and (property "EMAIL")))

Thanks. It seems it will take more lisp than I can handle. But let me try.

I think there is a potential to combine orgmode tags and properties, with a little more lisp may be, along with version control to create small database applications.

It would be good to design something as a proof-of-concept.
