# Phygital Discovery

Phygital bridges the gap between the physical and digital world. The objective is to bring the best of the physical experience into the digital realm and vice versa. Sunbird Knowlg uses the [DIAL spec](https://github.com/sunbird-specs/DIAL-specs/blob/main/README.md) to power the phygital discovery of assets. This capability is already massively used across India with billions of DIAL QR codes already in circulation.

**Key Capabilities:**

1. Flexible codification for easy printing by publishers
2. Ability to use an online code/ID registry with resource descriptor metadata
3. Ability to codify any physical learning resource
4. Ability for any app to scan, obtain metadata, and provide personalized learning experience to users

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowlg.sunbird.org/learn/capabilities/phygital-discovery.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
