International Alphabet of Sanskrit Transliteration
Let an agent explain the International Alphabet of Sanskrit Transliteration and its conventions, relay its history and use from Indological sources, describe adaptations for other languages, and distinguish IAST from ISO 15919, Harvard-Kyoto, ITRANS and popular romanisation.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the International Alphabet of Sanskrit Transliteration and its conventions, relay its history and use from Indological sources, describe adaptations for other languages, and distinguish IAST from ISO 15919, Harvard-Kyoto, ITRANS and popular romanisation.
A transliteration scheme for representing Sanskrit and related Indic languages in the Latin alphabet with diacritics, standardised at the 1894 Geneva Oriental Congress and used in scholarly publications to render Devanagari and other Indic scripts losslessly, with macrons for long vowels, dots under retroflex consonants and other marks, and adapted for languages such as Punjabi in schemes like the Bhardwaj IAST transliteration; IAST is distinct from ISO 15919, Harvard-Kyoto and informal romanisations.
What it is for: Romanising Sanskrit and Indic scripts for scholarship.
It can be explain conventions; relay history and use; describe adaptations; distinguish from other schemes.

How it is recognised
Scholarly romanisation of Sanskrit
IAST with diacritics; adaptations such as the Bhardwaj IAST transliteration for Punjabi
ISO 15919 is a broader standard; Harvard-Kyoto and ITRANS use ASCII; popular romanisation is informal

- How should Indological sources be linked?
- The registry entry has a merged alias naming a Punjabi adaptation; should it be split off?
