• Identify the boundaries of meaningful content units.
• Distinguish between pages, sections, components, and fragments.
• Understand navigation structure and content hierarchy.
• Map URLs to semantic entities in a predictable way.

• Be represented by a single canonical URL.
• Have a stable id identifying the page within the site.
• Contain or reference descriptive metadata such as name, description, and intent.
• Be semantically distinguishable from subcomponents like sections.

Pages may contain multiple sections, but sections are not pages unless explicitly declared as such.

• id — stable identifier for the page.
• url — the canonical URL of the page.

Recommended but not required:

• name — the human-readable page title.
• description — concise explanation of what the page covers.
• intent — explains what the page aims to achieve.
• section — one or more section declarations.
• parent — if the page belongs to a hierarchical structure.

• AI agents MUST treat each page as a standalone semantic unit anchored to its canonical URL.
• Agents SHOULD consider page-level metadata as context for all subordinate sections unless overridden.
• If multiple URLs map to the same page, agents SHOULD defer to the canonical URL.
• If a resource lacks a page declaration, AI SHOULD infer page-like behavior from URL structure and context, with reduced confidence.

Page-level declarations provide the highest-level metadata anchor for AI reasoning within a site.

• section — structural subcomponents of a page.
• parent — defines page hierarchy (e.g., section listings, subpages).
• canonical — determines the authoritative URL for the page.
• name / description / intent — define what the page is and why it exists.
• site — pages belong to and define the navigable form of a site.

{
  "page": {
    "id": "lighting-guide",
    "url": "https://photographyselect.com/guides/lighting/"
  }
}

Expanded example including metadata and sections:

{
  "page": {
    "id": "lighting-guide",
    "url": "https://photographyselect.com/guides/lighting/",
    "name": "Lighting Guide",
    "description": "A foundational guide explaining natural and artificial light for portrait photography.",
    "intent": "Teach photographers how to use lighting effectively in various scenarios.",
    "sections": [
      { "id": "natural-light" },
      { "id": "studio-light" }
    ]
  }
}

• It defines a stable page identifier and canonical URL.
• Its metadata is consistent with the declared purpose of the page.
• It follows all normative rules for page-level structure defined here.
