Currently this is a Base64 encoded serialized value of the specific Bloom filter class used by [JSONoid](https://github.com/dataunitylab/jsonoid-discovery), but we plan to make this a more reusable format.\n\nBloom filters are useful to check if specific values were observed for a particular property without the need to store all the values.\n\n### Histogram\nproperty           | description\n:--                | :--\n`bins`             | An array of two-element arrays where the first element is the mean of the bin and the second is the number of elements in the bin\n`hasExtremeValues` | A Boolean indicating whether the histogram contains values which cannot be represented in the given bounds. This usually only occurs for extremely large absolute values and is rarely observed in practice\n\n### Statistics\nproperty   | description\n:--        | :--\n`variance` | The variance of all values of this property\n`stdev`    | The standard deviation of all values of this property\n`skewness` | The skewness of all values of this property\n`kurtosis` | The kurtosis of all values of this property\n\n## Arrays\nproperty          | description\n:--               |:--\n`lengthHistogram` | A [histogram](#Histogram) of array lengths\n\n## Booleans\n\nproperty  | description\n:--       |:--\n`pctTrue` | Percentage of the Boolean values which are `true`\n\n## Integers\n\nproperty         | description\n:--              | :--\n`bloomFilter`    | A [Bloom filter](#bloom-filter) of integer values\n`distinctValues` | An estimate of the number of distinct values (cardinality) of this property\n`histogram`      | A [histogram](#histogram) of integer values\n`statistics`     | A set of [statistics](#statistics) of integer values\n\n## Numbers\n\nproperty         | description\n:--              | :--\n`bloomFilter`    | A [Bloom filter](#bloom-filter) of number values\n`distinctValues` | An estimate of the number of distinct values (cardinality) of this property\n`histogram`      | A [histogram](#histogram) of number values\n`statistics`     | A set of [statistics](#statistics) of number values\n\n## Objects\n\nproperty         | description\n:--              | :--\n`fieldPresence`  | An object where the value represents the percentage of the time the corresponding key appears\n\n## Strings\nproperty          | description\n:--               |:--\n`bloomFilter`     | A [Bloom filter](#bloom-filter) of string values\n`distinctValues`  | An estimate of the number of distinct values (cardinality) of this property\n`lengthHistogram` | A [histogram](#Histogram) of string lengths\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdataunitylab%2Fjson-schema-profile","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdataunitylab%2Fjson-schema-profile","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdataunitylab%2Fjson-schema-profile/lists"}
