Schema

[pathumego]

Following our discussion I am posting the simple YAML structure that I propose to use as a base.

# Comments
metadata:
	- map:
		- version:
		- description:
		- source:
		- authour:
		- copyright:
		- license:
		- script:
		- language:
	- encoding:
		- name:
		- source:
		- author:
	- font:
		- name:
		- source:
		- author:
mapping:
- combinations:
               ªè: "கெ"
		ªé: "ஙெ"
		ªê: "செ"
		ªë: "ஞெ"
- base:
		ã: "ஏ"
		ä: "ஐ"
		å: "ஒ"
		æ: "ஓ"
		è: "க"
- marks:
		§: "ு"
		ª: "ெ"
		«: "ே"
		¬: "ை"

• Text should be processed in the order
• [Combinations, base, marks] This classification dose not do much in the conversion process I think. However if this data is important we can classify. Either way mapping=mapping.combinations,mapping.base, mapping.marks
• Many-to-one: Multiple visual representations of the same codepoint should be added as two values in the map.

Above parsed to JSON <with https://www.json2yaml.com/>
