Web Capture Entity Reference

Fields

Warning: This schema is not yet stable.

  • cdx (array of objects): each entry represents a distinct web resource (URL). First is considered the primary/entry. Roughly aligns with CDXJ schema.
    • surt (string, required): sortable URL format
    • timestamp (string, datetime, required): ISO format, UTC timezone, with Z prefix required, with second (or finer) precision. Eg, "2016-09-19T17:20:24Z". Wayback timestamps (like "20160919172024") should be converted naively.
    • url (string, required): full URL
    • mimetype (string): content type of the resource
    • status_code (integer, signed): HTTP status code
    • sha1 (string, required): SHA-1 hash in lower-case hex
    • sha256 (string): SHA-256 hash in lower-case hex
  • archive_urls: An array of "typed" URLs where this snapshot can be found. Can be wayback/memento instances, or direct links to a WARC file containing all the capture resources. Often will only be a single archive. Order is not meaningful, and may not be preserved.
    • url (string, required): Eg: "https://example.edu/~frau/prcding.pdf".
    • rel (string, required): Eg: "wayback" or "warc"
  • original_url (string): base URL of the resource. May reference a specific CDX entry, or maybe in normalized form.
  • timestamp (string, datetime): same format as CDX line timestamp (UTC, etc). Corresponds to the overall capture timestamp. Can be the earliest of CDX timestamps if that makes sense
  • release_ids (array of string identifiers): references to release entities
