# OnCo > A public, cited knowledge graph of oncology: cancers, fronts, technologies, targets, treatments and tests, companies, institutions, people, pathways, trials, pairings, roadmaps, key papers, journals, bottlenecks and ideas, one page per object, each with a plain-English TL;DR, a technical summary, dated facts and links to primary sources. Not medical advice. 72 records in 18 kinds: 8 diagnoses, 11 fronts, 10 technologies, 5 targets, 9 drugs, 3 companies, 4 institutions, 1 pathways, 4 terms, 4 trials, 1 pairings, 1 roadmaps, 3 ideas, 1 collections, 1 people, 4 bottlenecks, 1 key papers, 1 journals. Every fact is dated and linked to a primary source; where a number is not sourced it is omitted. Facts may be incomplete or out of date: cite the OnCo page and check the primary source it links before relying on anything that matters. ## Licence and attribution - Data: CC BY-NC 4.0 (https://creativecommons.org/licenses/by-nc/4.0/).

WebMCP: browsers with a model context get onco_search and onco_get_entity on every page. - Every record page carries tags to its Markdown, JSON and Turtle twins, schema.org JSON-LD (typed by kind, with a BreadcrumbList), and a hidden navigation landmark labelled "Machine-readable versions" whose links carry data-onco-id, data-onco-kind and data-onco-format;
carries data-onco-id and data-onco-kind. - Language is a reader-side toggle on the same URL, so there is one URL per record and no hreflang variants. ## Machine-readable corpus - [All records as JSON](https://onco.cc/api/v1/all.json): every entity with defaults applied plus a backlink map (several megabytes) - [All records as NDJSON](https://onco.cc/api/v1/all.ndjson): one entity per line with its route - [Per kind](https://onco.cc/api/v1/drugs.json): /api/v1/.json and /api/v1/.csv for each kind listed below - [Entity schema](https://onco.cc/api/v1/schema.json): JSON Schema (draft 2020-12) of one record, generated from the Zod schema that validates the corpus - [RDF N-Triples](https://onco.cc/api/v1/onco.nt): schema.org terms, owl:sameAs to Wikidata - [Concept index](https://onco.cc/api/v1/embeddings.json): TF-IDF vectors used by the site search (binary at embeddings.bin) - [Similar pages](https://onco.cc/api/v1/similar.json): top 8 similar records per id with the shared links - [Metadata](https://onco.cc/api/v1/meta.json): build date, counts per kind, licence, the file list - [Feeds](https://onco.cc/feeds/changelog.xml): Atom feeds at /feeds/changelog.xml, /feeds/regulatory.xml, /feeds/calendar.xml, /feeds/pulse.xml and /newsletter/feed.xml; iCalendar at /catalysts/feed.ics - [Releases](https://github.com/judegomila/OnCo/releases): the corpus attached to each tagged release as JSON, NDJSON, CSV and schema ## Kinds - [Diagnoses](https://onco.cc/diagnoses/): One page per dementia type or related condition: what it is, how it is assessed, and what is known.
