"Return an alist of refs to absolute path of Org-roam files.
When `org-roam-include-type-in-ref-path-completions' and
INTERACTIVE are non-nil, format the car of the
completion-candidates as 'type:ref'.
FILTER can either be a string or a function:
- If it is a string, it should be the type of refs to include as
candidates (e.g. \"cite\" ,\"website\" ,etc.)
- If it is a function, it should be the name of a function that
takes three arguments: the type, the ref, and the file of the
current candidate. It should return t if that candidate is to be
included as a candidate."

information: title, tags, and type if
