{"name":"PToB source page formats","version":1,"description":"Alternate representations of the finished published HTML, generated after translation. Follow a page’s typed alternate link. This is a retrieval convenience, not a search ranking or AI inclusion requirement.","formats":[{"query":"format=json","mediaType":"application/json","example":"https://ptob.dev/research/?format=json"},{"query":"format=markdown","mediaType":"text/markdown","example":"https://ptob.dev/de/forschung/?format=markdown"}],"applicability":"Static source pages that advertise these alternates. Search, error pages, PDF readers and language-reference utilities do not support the format query. Use a single format parameter without other query parameters; fragments remain canonical section locators. PDFs and data retain their original URLs and media types.","negotiation":"Default responses remain HTML, including Accept: application/json. Explicitly preferred Accept: text/markdown is also supported. The explicit query URLs avoid sharing the CDN HTML cache key and require no custom request headers.","fields":{"canonical":"Original HTML publication URL; canonical heading locators support source attribution.","representations":"Directly fetchable alternate URLs for this canonical source; documentation links to this descriptor. Also included in Markdown frontmatter and HTTP Link headers.","title":"Finished page title.","description":"Finished meta description.","language":"Finished HTML language; German pages do not replace English original papers.","social":"Existing Open Graph and Twitter preview tags, including actual image URLs/alternatives/dimensions when supplied. Missing values are omitted.","dates":"Only known page publication/modification dates. Original manuscript dates stay in citations and structuredData; missing dates are omitted.","authors":"Names resolved from page/article metadata, only when present.","citations":"Original paper citation metadata when present.","provenance":"SHA256 of the exact finished source HTML, source URL and existing rights/license metadata when available. No license is inferred.","contentUsage":"Shared publisher preferences for this source and representation; separate from copyright licenses. Existing CC BY/MIT terms are not revoked. Search and user-requested retrieval remain allowed for public sources. No extra citation requirement or attribution quota is imposed beyond existing source terms.","content":"Main-content Markdown, ordered headings with real canonical anchors when present, and source links. Preserves tables, measurement denominators and qualifications; excludes navigation, scripts and decorative controls. It is source content, not an AI-generated summary.","structuredData":"Unmodified JSON-LD from the finished page, including stable entity/source IDs."},"indexing":"Format-query responses declare the HTML canonical and noindex to avoid duplicate indexing. Canonical page indexing remains unchanged. Preview sources retain noindex and grant no content-use permission.","errors":{"400":"Duplicate format or mixed query parameters.","404":"Unknown source path.","406":"Unknown format or format unavailable for this resource."},"search":"https://ptob.dev/search-api.json"}
