Structural Data is the skeleton which the rest of the data fleshes out.

Some of these files are deprecated and should not be used for future development. We should remove them ASAP.

• sutta.json is replaced by name files and text_extra_info.jsonas per suttacentral/suttacentral#1771
• grouping.json and pitaka.json are replaced by super-tree.json
• The division folder is replaced by name and tree.
• But name is now in sc_bilara_data do delete it from here.

The current files are as follows.

• tree files give the tree structure of the whole navigation.
• nav_only_tree: defines texts for which there is no text, only navigation.
• super- files give the "superstructure", i.e. the higher-level structure as far as the individual text or division.
• text_extra_info gives supplementary information about texts.
• super_extra_info is the same, but for the super- files.
• language.json defines the language of each text or division.
• sect.json defines the sect (or better, "school") of Buddhism to which the text belongs.
• shortcut.json defines the navigation shortcuts.
• child_range.json defines the acronym and sutta range number of the children of the given ID. This is used as a navigation aid, it lets the user know what is contained.
• super_root_lang.json defines the highest level of the tree to which a language can be assigned. All children have that root language.
