Lines
The Lines table contains all the Sikh bani and panthic content, across all sources.
Many lines must belong to one Shabad.
The content is unordered by default, and must be ordered by order_id. The id is a four-letter, immutable identifier that will refer to the same line across database versions.
Currently, the gurmukhi stores an ASCII representation of Gurbani. They may be converted to unicode with gurmukhi-utils.
