AdBuyMCP's own vocabulary

# What is a lawful-basis manifest?

A record attached to every compiled channel plan naming each data source used, the lawful basis it relies on, the conditions that come with it, and the warnings raised while compiling. The compiler writes it automatically as it builds the plan.

What it means here

## Here is what the term means for a UK buyer

The definition above holds anywhere. Buying media in the UK adds the detail below, including where AdBuyMCP does something different.

It exists so the answer to 'where did this audience come from?' is a document a data protection officer can read, and so that the record a reviewer sees is the same record the compiler acted on. It attaches the conditions you still owe, such as an assessment on file or a vendor attestation verified on connection, so it tells you what remains to be done. It is not a compliance certificate, and turning its conditions into enforced launch gates is work AdBuyMCP has not finished.

Related terms

## These terms sit next to this one

Most confusion in media buying comes from two adjacent terms being used interchangeably, so these are the neighbours worth reading next.

- ### [Lawful basis](https://adbuymcp.com/glossary/lawful-basis)
  The legal ground relied on to process personal data, of which six exist under UK GDPR and at least one must be identified before processing begins. In advertising the two that matter are consent and legitimate interests, and the basis has to be settled before the processing starts.
- ### [UK GDPR](https://adbuymcp.com/glossary/uk-gdpr)
  The United Kingdom's data protection regime, retaining the structure of the EU General Data Protection Regulation. Requires a lawful basis for processing personal data and gives individuals rights over data about them.
- ### [Persona compiler](https://adbuymcp.com/glossary/persona-compiler)
  The deterministic stage that turns one described audience into the native targeting specification each channel accepts, with a fidelity score and a lawful-basis manifest. Depending on the channel, that specification is segment identifiers, attribute combinations, show allowlists, venue packs or keyword seeds.
- ### [TCF consent string](https://adbuymcp.com/glossary#tcf)
  A standardised, encoded record of what a user consented to, produced at the point of collection and readable by every participant downstream. It is passed along the advertising supply chain so that each participant can check whether it has a basis to process that person's data before it does.
