Schema

BlobAttribute

A typed value in a [Blob]'s attribute map.

The map is the extension point: a new fact about a blob is a new key, never a new column, so adding one does not touch the schema, the wire framing or older readers (they ignore keys they do not know). Values stay typed so a reader never has to guess whether "7" is a number.

Shape

One of 3 shapes:

  1. type: "int"

    FieldTypeDescription
    typerequired"int"
    valuerequiredinteger (int64)
  2. type: "text"

    FieldTypeDescription
    typerequired"text"
    valuerequiredstring
  3. type: "token"

    One of a fixed set of tokens, spelled in the key's documentation - the same rule as every other enum in this file.

    FieldTypeDescription
    typerequired"token"
    valuerequiredstring
Example
{
  "type": "int",
  "value": 0
}

The contract has no example values, so example bodies are generated from each schema: every field is shown with a placeholder of its type.
