The Service is a set of API that enables create, retrieve, delete, publis DIAL refers to *Digital Infrastructure for Augmented learning*. Sunbird Knowlg uses the [DIAL spec](https://github.com/sunbird-specs/DIAL-specs/blob/main/README.md) to power the phygital discovery of assets. It provides tools for DIAL code management. The DIAL powers the discovery of digital resources using physical artefacts like QR codes, can be extended to other physical artefacts. The DIAL code does the loose binding of digital assets with physical artefacts. In practice, physical artefacts will be published once, serving as coordinate to the discovery of digital resources. Digital resources can be published and modified later multiple times, this is done to improve digital resources. In short, the DIAL code serves as a coordinate for digital resources discovery, where the digital resources can be modified, improved and personalised at runtime. ### DIAL code usage workflow * DIAL code acts as a bridge between physical and digital artefacts * DIAL code is generated and linked to a folder in a collection * User scans the DIAL code and accesses all the linked assets in that folder * This enables easy extension and modification of assets accessed through a DIAL code ![DIAL code as coordinate to discover digital coordinates](https://1767651289-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FaanfWbeVT74C5lXDPde3%2Fuploads%2F7yFN1AMGtCTD9t3EHIq5%2FDIAL_code_%20flow.png?alt=media\&token=82da9aa4-98e1-41c0-ac2c-99cf447389e8) ### DIAL Spec {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://knowlg.sunbird.org/learn/product-and-developer-guide/dialcode.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
