# Knowledge Assets

A Knowledge Asset is published graph data with provenance and integrity. It packages RDF statements so other nodes can verify who published them, what was published, and whether the content still matches its commitment. Each publish mints one Knowledge Asset — a single ERC-721 token — that can describe multiple related entities.

![Knowledge Assets](https://4166702221-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3Xvop5eIlAwwtLtmyreq%2Fuploads%2Fgit-blob-29b1e71e98e35d42aae41d420bc1f7f26ca7fa5f%2Fknowledge-assets.png?alt=media)

Use Knowledge Assets when knowledge needs to survive beyond local or team memory:

* facts that must be independently verifiable
* records that should have a durable identifier
* data that another party may endorse or verify
* final outputs from a multi-agent workflow

Agents should not convert every note into a Knowledge Asset. Most work starts in Working Memory and becomes a Knowledge Asset only after it is worth finalizing.

## Knowledge Assets and UALs

The Knowledge Asset is minted to its author as an ERC-721 token; the publisher pays the TRAC cost. After publication, the asset is addressed through a UAL of the form `did:dkg:{chainId}/{contract}/{kaId}`, where `kaId` is the ERC-721 token id. The UAL stays the same even when the asset's content is updated, so citations remain valid across revisions.

Use the UAL when another workflow needs to cite, fetch, or verify published knowledge. Use the Context Graph when the workflow needs the larger scoped memory domain around that asset.

## Publisher Authority

Publishing records who finalized the knowledge. When a Publishing Conviction Account is active, a registered publishing agent can use that account's conviction path. If the agent is not registered or the account is not eligible for the publish, the publisher path falls back to direct spend.

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. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.origintrail.io/how-dkg-works/knowledge-assets.md?ask=<question>&goal=<user_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.
