Build item.attributes Object from Items Data Frame

Reverse engineers the item.attributes object structure required by AIGENIE from a validated items data frame. This allows GENIE to work with user-provided items by reconstructing the expected attribute structure.

Usage

build_item_attributes_from_items(items)

Arguments

items

A validated data frame with columns: statement, attribute, type, ID (already processed by items_validate_GENIE)

Value

A named list where:

• Names are the unique item types from items$type

• Each element is a character vector of unique attributes for that type

• All values are normalized (lowercase, trimmed) to match AIGENIE expectations
