Metadata & Comment Panel on the right - C (yellow)
## Information Panel (C)
The Information Panel on the right hand side of the Nodes workspace environment, which you can open with the Information ('i') button at the top right , contains two tabs:
* the [Metadata Panel](#metadata-c1) - to add and extract extra information to or from your Node components.
* the [Comments Panel](#comments-c2) - to add and manage comments on your (textual/visual = currently PDF) components.
## Metadata (C1)
To add Metadata to your Node object, open the Metadata Panel, currently situated on the right hand side. You can open it by pressing the Information ('i') button at the top right
The ability, and even requirement, to add Metadata is an important part of Nodes. Metadata is information about the Nodes objects that helps guide and ease its sharing and reproduction. There are many different forms of Metadata, some of which, supported by Nodes, are:
* #### [Title](/create-and-publish/create-a-node/add-information/add-metadata.md#title) - you can name your component here
* #### [Citations](/create-and-publish/share/cite.md) - Get a [formatted citation](/create-and-publish/share/cite.md) to any component
* #### [License](/create-and-publish/create-a-node/add-information/add-license.md)
* #### [CEDAR Link](/create-and-publish/create-a-node/add-information/add-metadata.md#cedar-link)
* #### [Ontology URL](/create-and-publish/create-a-node/add-information/add-metadata.md#ontology-url)
* #### [Description](/create-and-publish/create-a-node/add-information/add-metadata.md#description)
* #### [Keywords](/create-and-publish/create-a-node/add-information/add-metadata.md#keywords)
* #### [Controlled Vocabulary](/create-and-publish/create-a-node/add-information/add-metadata.md#controlled-vocabulary)
* #### [Component Type](/create-and-publish/create-a-node/add-information/add-metadata.md#component-type)
Furthermore, you can grab a component's [content identifier](/technical-background/persistent-identifiers-101.md#solving-content-drift) for [easy re-use](/create-and-publish/share.md#share-and-re-use-via-cid).
Further information on Metadata and the types you can add to Nodes is found in [Metadata](/technical-background/open-state-repository/metadata.md)
## Comments (C2)
Comments on your Node objects can be managed from the same panel, under the Information 'i' button, different tab. You can add them from the viewer panel, using the highlighter button
Examples of commenting with a link to internal Node objects.
See the [Add Comments](/create-and-publish/create-a-node/add-information/add-comments.md) section for more information.
