Why we document

India is not short of heritage. What it is short of is record: measured, dated, citable documentation of what those buildings actually are.

Photography is not documentation. A photograph records a viewpoint. It cannot tell you the thickness of a wall, the profile of a plinth moulding, the relationship between a sanctum and the envelope around it or how far the superstructure has moved since it was built. Those are the questions conservation asks and a photograph answers none of them.

What a record is

A Vaayil record is a single monument, surveyed on stated dates by stated methods, drawn and published with its evidence attached. It carries:

• where the building is and how precisely we are willing to say so
• when it was built and how confident that dating is
• what condition it is in, part by part and the date that assessment was made
• how the survey was performed, with what software, to what tolerance
• what we were unable to establish

The last item is not a disclaimer. It is a field of the record, it is required by the schema and a record cannot be published without it.

Why openness

A record held privately is a record that dies with the studio that made it. Vaayil publishes under a licence that permits scholarship, teaching and non-commercial reuse, with a permanent URL and a citation for every record, so that a measurement taken in 2026 is still addressable in 2056.

Documentation is the beginning, not the destination. Without it, conservation is guesswork performed at scale on objects that cannot be replaced.
