Blueprint

Source: src/AWS/BedrockDataAutomation/Blueprint.ts

An Amazon Bedrock Data Automation Blueprint — a JSON schema describing the custom output fields to extract from documents, images, audio, or video. Attach blueprints to a DataAutomationProject via its customOutputConfiguration.

Creating Blueprints

Document blueprint with custom fields

import * as BDA from "alchemy/AWS/BedrockDataAutomation";

const blueprint = yield* BDA.Blueprint("InvoiceBlueprint", {
  type: "DOCUMENT",
  schema: JSON.stringify({
    $schema: "http://json-schema.org/draft-07/schema#",
    description: "Extract invoice fields",
    class: "invoice",
    type: "object",
    properties: {
      invoice_number: {
        type: "string",
        inferenceType: "explicit",
        instruction: "The invoice number",
      },
    },
  }),
});

Attach a blueprint to a project

const project = yield* BDA.DataAutomationProject("Docs", {
  standardOutputConfiguration: {},
  customOutputConfiguration: {
    blueprints: [{ blueprintArn: blueprint.blueprintArn }],
  },
});
