# Objects Overview

OORT Storage is an object store that uses unique key-values to store as many objects as you want. You store these objects in one or more buckets, and each object can be up to 100 GB in size. An object consists of the following:

### **Key**

The name that you assign to an object. You use the object key to retrieve the object. 

### **Value**

The content that you are storing.

An object value can be any sequence of bytes. Objects can range in size from zero to 2 GB. For more information, see [Upload Objects](/oort/oort-storage/manage-storage/work-with-objects/upload-objects.md).

### **Metadata**

A set of name-value pairs with which you can store information regarding the object. You can assign metadata, referred to as user-defined metadata, to your objects in OORT Storage. OORT Storage also assigns system-metadata to these objects, which it uses for managing objects.

## 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, and the optional `goal` query parameter:

```
GET https://docs.oortech.com/oort/oort-storage/manage-storage/work-with-objects/objects-overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
