# SEO metadata

OGP renders shared metadata in its existing Hugo templates. No template override or extension framework is required for these settings.

| Setting | Behaviour |
| --- | --- |
| `params.seo_title` | Optional complete homepage title. Defaults to the site title, independently of the description. Language-specific site parameters can supply translated titles. Guide titles keep their existing guide-first edition format. |
| Page `og_image`, then `params.og_image`, then `params.logo_image` | Social image precedence. Hugo resolves relative image paths against the build's base URL; absolute URLs are preserved. Without an image, image tags are omitted. OGP does not guess image dimensions or image descriptions. |
| `params.logo_image` | Publisher logo in WebSite and CreativeWork structured data. Omitted when unconfigured. Use an existing asset or absolute image URL. |
| Page `guide_license` | Explicit publication licence text, also emitted in metadata and CreativeWork structured data with Markdown formatting removed. If absent, no licence is inferred from website copyright or another edition. |

Social page URLs use Hugo's page permalink. Configure the build base URL for the intended host. This does not change canonical URL policy.

CreativeWork authors use the same existing contributor discovery and `founder: true`, `role: creator` selection as the visible guide creators. Existing edition filtering is retained. A person's explicit URL takes precedence over their GitHub profile; a missing URL is omitted. If no creators are known, the author property is omitted.

OGP does not advertise a `/search?q=…` search endpoint. Its existing search interface is unchanged. Historical editions do not claim to be based on the latest edition. These changes introduce no new adaptation relationship configuration.

Publication discovery, reader templates, translation/PDF availability, routes, canonicals, sitemap/hreflang generation and XML/JSON feeds retain their existing behaviour.

Emit a schema-compatible license value.

guide_license is documented and tested as descriptive text, such as CC BY 4.0. The CreativeWork template passes that text to license without converting it to a URL or a nested CreativeWork. Schema.org defines this property as URL or CreativeWork, so the structured data is non-conforming and may have reduced interoperability with schema-aware consumers.

Keep the input contract, but map descriptive text to a nested CreativeWork, or change the contract to require a canonical licence URL. Update docs/using/seo-metadata.md and tests/Core/HugoSeoMetadata.Tests.ps1 to match the selected representation.

In
`@system/OpenGuidePlatform.Hugo.Guides/layouts/_partials/JSON-LD/creativework.html`
at line 78, Update the CreativeWork JSON-LD template’s license field to emit a
schema-compatible representation while preserving the documented descriptive
guide_license input, preferably by wrapping the text in a nested CreativeWork.
Align the license documentation in seo-metadata.md and the corresponding
HugoSeoMetadata.Tests.ps1 expectations with the selected representation.

P2 Badge Inherit guide licenses on edition pages

When a guide declares its licence on the guide root, as both reference guides do in content/Guide1/_index.md and content/Guide2/_index.md, an edition page does not inherit that parameter, so .Params.guide_license is empty and the CreativeWork license is silently omitted; the same lookup in baseof.html also omits the license meta tag. The new fixture masks this for real sites by placing guide_license directly on its edition. Resolve the owning guide section's licence as a fallback while retaining a page-level override.
