# Function: projectStandardIndex()

> **projectStandardIndex**(`builder`, `collection`, `info`, `ctx`): [`CollectionIndexProjection`](https://docs.bitbadges.io/sdk/reference/interfaces/collection-index-projection)

Defined in: [packages/bitbadgesjs-sdk/src/api-indexer/info-builders.ts:90](https://github.com/BitBadges/bitbadgesjs/blob/master/packages/bitbadgesjs-sdk/src/api-indexer/info-builders.ts#L90)

Project a standard's computed `info` into its [CollectionIndexProjection](https://docs.bitbadges.io/sdk/reference/interfaces/collection-index-projection),
using the builder's `index()` when present and a status-only default otherwise.
Single source of the default so every indexed standard behaves consistently.
