# 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).
