Properties are key-value pairs associated with an entry. They live in a
special drawer with the name
property is specified on a single line, with the key (surrounded by colons)
first, and the value after it:
* CD collection ** Classic *** Goldberg Variations :PROPERTIES: :Title: Goldberg Variations :Composer: J.S. Bach :Publisher: Deutsche Grammophon :NDisks: 1 :END:
You may define the allowed values for a particular property ‘:Xyz:’ by setting a property ‘:Xyz_ALL:’. This special property is inherited, so if you set it in a level 1 entry, it will apply to the entire tree. When allowed values are defined, setting the corresponding property becomes easier and is less prone to typing errors. For the example with the CD collection, we can predefine publishers and the number of disks in a box like this:
* CD collection :PROPERTIES: :NDisks_ALL: 1 2 3 4 :Publisher_ALL: "Deutsche Grammophon" Philips EMI :END:
or globally using
org-global-properties, or file-wide like this:
#+PROPERTY: NDisks_ALL 1 2 3 4
Set a property. This prompts for a property name and a value.
Remove a property from the current entry.
To create sparse trees and special lists with selection based on properties, the same commands are used as for tag searches (see Tag searches). The syntax for the search string is described in Matching tags and properties.
