# How to deal with Additional Information

Any piece of Additional Information is encoded as data - of particular here it will be as digital data.

Each data object will need Representation Information so that the data can be understood and used. Therefore [Representation Information](/labdrive/data-curation-and-preservation-1/how-to-deal-with-additional-information/representation-information.md)is described first.

Provenance is described in some detail, in [Provenance Information](/labdrive/data-curation-and-preservation-1/how-to-deal-with-additional-information/provenance-information.md), as an example.

Many of the types of Additional Information are needed to create an Archival Information Package, as described in [OAIS and ISO 16363](/labdrive/concepts/oais-and-iso-16363.md).

# 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://docs.libnova.com/labdrive/data-curation-and-preservation-1/how-to-deal-with-additional-information.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.
