General notes

  • locationID: Every location in Li is identified with a unique locationID, comprised of iso1, iso2, and fips codes from https://github.com/hyperknot/country-levels. Examples: iso1:US = United States, iso1:us#iso2:us-al = State of Alabama, iso1:us#iso2:us-al#fips:01125 = Tuscaloosa County, Alabama.
  • slug: Many reports have a slug for a location, which is a url-friendly location representation, e.g. "butte-county-california-us".
  • Combining data sources: Sometimes multiple sources cover the same location. For example, JHU, New York Times, and California sources may all submit data for California. These sources are combined in the final reports where possible, and conflicts are resolved by priority. See Combining Data Sources.
  • Integration testing samples: samples for automated test verification are in tests/integration/events/reports/expected-results.

Combining Data Sources

The data fields in a given record can be supplied by many sources: one source may return cases and deaths, and another return hospitalizations and tests. The field dateSources shows where each field comes from.

A shorthand is shown for the date ranges for which the sources supplied data. For example, "2020-05-21..2020-06-18": "src" means that src supplied the data from 05-21 to 06-18.

If there are conflicts in the data (e.g., multiple sources return cases, but they're inconsistent), a warnings element is added. e.g.,

"warnings": {
  "2020-06-19": {
    "cases": "conflict (src1: 3, src2: 2, src3: 1)",
    "deaths": "conflict (src2: 22, src3: 11)"
  },
  ...
