Working with Annotations

Annotations are metadata fields attached to each archived file. Each annotation consists of one or more properties, defined when the annotation is created. For each property, you specify the property type and whether it is required.

You can define up to 20 annotations in total, each with up to 15 properties. When uploading a document, you can apply up to 10 annotations, each with up to 10 properties.

In addition to annotations, other required fields may apply depending on the file type. These settings ensure that archived files are correctly categorized and can be efficiently searched and retrieved later. You must assign at least one annotation to each document you upload.

Supported Property Types

The following property types are supported when defining annotations:

• string – text up to 200 characters
  e.g., "documentType": "invoice"
• integer – numeric values
  e.g., "invoiceNumber": 12345
• date-time – timestamp in ISO 8601 format
  e.g., "createdAt": "2025-08-14T13:45:00Z"
• string array – list of strings (up to 15 values)
  e.g., "tags": ["finance", "Q3", "urgent"]

These flexible property types allow you to model metadata tailored to your business use case – such as document type, validity period, reference numbers, or custom tags.
