API for manipulating #+PROPERTY entries?

API for manipulating #+PROPERTY entries?

Hoi,

Is there an API for manipulating properties that are set in #+PROPERTY
lines before the first headline of a file (i.e., not in a property drawer)?

I've got some properties that (a) make sense when set for the whole file,
and (b) the file contains multiple first level headings (which isn't going
to change).

Using org-entry-put when point is before the first headline throws a
"Before first headline" error (when when the #+PROPERTY line already exists
and I want to update an existing entry).

There is no API for keywords.

`org-entry-put' is for node properties. Those do not necessary have
a keyword equivalent. Reciprocally, some keywords cannot be translated
into node properties.

You might find a function like this one:

helpful. There are some variations that do similar things.
