TODO Properties in org-mode

Properties in org-mode

Problem - the beggining

Let’s say we’ve got the following org file

* Headline 1 with name taken from properties - src_elisp{(org-entry-get nil "Name")}
:PROPERTIES:
:Title:     Goldberg Variations
:Name:  J.S. Bach
:END:

** SubHeadline 

Since properties are not inherited by default we cannot add src_elisp{(org-entry-get nil "Name")} in the subheadline, because it ends with an error.

But we can turn the properties inheritance on like below (Do observe the usage of 'selective flag - without it the example wouldn’t work!):

# -*- mode: Org; org-use-property-inheritance: t -*- 
* Headline 1 with name taken from properties - src_elisp{(org-entry-get nil "Name")}
:PROPERTIES:
:Title:     Goldberg Variations
:Name:  J.S. Bach
:END:

** SubHeadline  - src_elisp{(org-entry-get nil "Name" 'selective)}

1. How to selectively inherit properties?

Problem extension

Now we would like to keep properties in a different files and treat it as some kind of database

:PROPERTIES:
:Title: Some New Title
:Name:  Newman
:END:

:PROPERTIES:
:Title: Title22222
:Name:  Name22222
:END:

1. Approach 1

   This won’t work:

   # -*- mode: Org; org-use-property-inheritance: t -*- 
   * Headline 1 with name taken from properties - src_elisp{(org-entry-get nil "Name")}
   #+INCLUDE: ./properties.txt
       
   ** SubHeadline  - src_elisp{(org-entry-get nil "Name" 'selective)}
   

2. Approach 2

   This does work but it’s less convenient:

   # -*- mode: Org; org-use-property-inheritance: t -*- 
   * Headline 1 with name taken from properties - src_elisp{(org-entry-get nil "Name")}
   #+INCLUDE: ./properties.txt
       
   ** SubHeadline  - src_elisp{(org-entry-get nil "Name" 'selective)}
   #+INCLUDE: ./properties.txt
   

Solution

It seems that 1.1.2.1 does not work because Subheadline has no content. If we add any latex white space or subsubheadline inside subheadline everything works ok.

1. Approach 4

   This does work but it’s less convenient:

   ,# -*- mode: Org; org-use-property-inheritance: t -*- 
   * Headline 1 with name taken from properties - src_elisp{(org-entry-get nil "Name")}
   #+INCLUDE: ./properties.txt
       
   ** SubHeadline  - src_elisp{(org-entry-get nil "Name" 'selective)}
   \nbsp{}
       
   # # The lines below wouldn't work
   #** SubHeadline  - src_elisp{(org-entry-get nil "Name" 'selective)}
   #** SubHeadline
