Enum RuleSource

    IanaMediaTypes,
    Iso4217,

The external standard or authority that a rule is derived from.

Mirrors the standards listed in the README. Use this to filter the catalog by authority level — e.g. alert hard on RuleSource::VastSpec violations while only logging RuleSource::Inferred advisories.

Variants

VastSpec

IAB Tech Lab VAST spec normative prose (explicit §-references)

VastXsd

IAB Tech Lab VAST published XSD schemas (structural and enum constraints)

Xml

W3C XML 1.0 well-formedness

Rfc3986

RFC 3986 URI syntax

IanaMediaTypes

IANA Media Types registry

Iso4217

ISO 4217 currency codes

AdId

Ad-ID registry format

Inferred

vastlint heuristic — no single external spec authority

SimidSpec

IAB Tech Lab SIMID spec normative prose

VmapSpec

IAB Tech Lab VMAP 1.0.1 spec normative prose

DaastSpec

IAB Tech Lab DAAST spec normative prose

DaastXsd

IAB Tech Lab DAAST published XSD schema

IndustryBestPractice

Industry best practice derived from real-world ad serving patterns; violation has a direct revenue or measurement impact.

CtvAdPortfolio

IAB Tech Lab CTV Ad Portfolio signaling guidance (finalised 2026-07-22). Distinct from RuleSource::VastXsd because the guidance is a published final standard while the accompanying vast_4.4.xsd is still a working-group draft.
