# Extract Data from a File

To extract data from a file, follow the steps in the previous section for getting a token with the `data:read` and `data:write` scopes, encoding the `urn` of the file using the `jsonlite::base64_enc()` function, and translating the file into SVF format using the `translateSvf()` function. Next, retrieve metadata for a file using the `getMetadata()` function, which returns an object with the `type`, `name`, and `guid` of the file. Note the `guid` and store it in `.Renviron`.

```
resp <- getMetadata(urn = myEncodedUrn, token = myToken)
myGuid <- resp$content$data$metadata[[1]]$guid
```

To get the object tree of a model, use the `getObjectTree()` function.

```
resp <- getObjectTree(guid = myGuid, urn = myEncodedUrn, token = myToken)
resp

# Agent Instructions: 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:

```
GET https://paulgovan.gitbook.io/autodeskr/model_derivative/extract_data_from_a_file.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
