Cada elemento resume la cobertura de datos de cada colección en un momento dado. **computed\_at** `integer` Fecha de la medición en segundos Unix. **db\_update** `integer` Fecha de la actualización de la base de datos medida, en segundos Unix. **affiliations\_collection** `object` Afiliaciones: `total`, instituciones colombianas (`colombian`, `colombian_without_minciencias_id`), `research_groups`, `with_citations` y desgloses por identificador externo (`external_ids_breakdown`), procedencia (`provenance_breakdown`) y tipo (`types_breakdown`). **works\_collection** `object` Productos: `total`, `with_doi`, `with_abstract`, `with_citations`, `with_apc_paid`, `open_access_status_known` y desgloses por procedencia y tipo. **person\_collection** `object` Personas: `total`, `with_orcid`, `with_citations`, `with_hindex`, `with_staff`, `with_cedula` (solo el conteo) y desgloses por identificador externo y procedencia. **sources\_collection** `object` Fuentes: `total`, `with_apc` y desgloses por identificador externo, licencia, acceso abierto, procedencia, cuartil Scimago y tipo de fuente. **patents\_count** `integer` Total de patentes. **projects\_count** `integer` Total de proyectos. **news\_count** `integer` Total de noticias. ```json 200 theme={null} [ { "affiliations_collection": { "colombian": 9491, "colombian_without_minciencias_id": 1727, "external_ids_breakdown":
