# Product Data

> The structured information that describes a product, its identity, attributes, composition, documentation and compliance evidence, across the systems that hold it.

## Definition

The complete set of structured information describing a product: its identifiers, commercial and
technical attributes, material composition, documentation, certification references and lifecycle
records, held across the systems that create and consume it.

## Expanded Explanation

In most organisations product data is distributed rather than centralised. Commercial attributes sit
in a product information system, engineering data in a lifecycle management system, batch records in
manufacturing systems, and compliance evidence in shared drives and supplier correspondence. Each
holds a partial view, and the same attribute frequently exists in several places with different
values.

Passport publication forces this to be resolved, because a passport must present one answer per
field. That requires deciding, for each attribute, which system is authoritative, how conflicts are
handled, who may change the value and how changes are recorded.

It also raises the standard of the data itself. Externally readable data must be complete, current,
consistent between fields, and structured to a defined schema rather than expressed as free text
that only internal staff can interpret.

## Why It Matters

Passport programmes rarely fail on the publication layer. They fail because required fields do not
exist in any system, exist with conflicting values, or exist only as documents. Establishing
ownership of each field early converts a compliance deadline into a tractable data project.

## Common Misconceptions

#### The product information system already holds everything

Product information systems are built for commerce, so they carry descriptions, imagery and
pricing. Substance, batch and conformity data usually live elsewhere and are rarely modelled at
the granularity a passport needs.
