# 5.1.4. Hierarchies
Knowing how geographic objects relate to each other over time as part of different hierarchies is important not only to be able to aggregate information to support decision making, when applicable, but also to ensure relational consistency between geographic objects.
One of the functions of GeoPrism Registry is to capture and use not only geographic relationships that exist between geographic objects (is within, lives in) but also other types of relationships such as administrative (is reporting to), health-related (covers, providing service to, refers to), and associative (is part of).
These different relationships can be represented in distinct **hierarchies** like those included in Figure 5.1.

## 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.geoprismregistry.com/readme/current-1/geoprism-registry-key-components/5.1-content/5.1-content-3.md?ask=&goal=
```
`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.
