# Overview

Registrants are at the heart of OpenSPP.

A registrant can be:

• A group

• An individual

Depending on the project’s requirements, a registrant can simply contain a name or full biographic information, ID document numbers, pictures, bank account numbers, phone numbers and more.

Important

Consider only collecting the data you really need when conducting a project.

## Individual

An individual is a registrant that represents a person. It will have all the fields of a registrant plus some additional ones.

## Group

A group is a registrant that represents a set of individuals. It will have all the fields of a registrant plus some additional ones.

For example, groups could represent:

• A household

• A family

• A school

Groups do not need to contain individuals registrants. They can just contain their number of members.

For example:

• Children: 3

• Elderly: 2

## Group membership

Individuals can be part of one or more groups. They can have specific roles in a group.

By default, the following roles exist:

• Head (There can be only one per group)

• Principal recipient (There can be only one per group)

• Alternative recipient

An admin has the right to add other roles using the configuration menu.

An individual can be the head of a group but have another or no role in another group.

## Registrants relations

When you need to store the relationship between registrants those relations can be useful.

You can define relationship type between different entities:

• Group - Group

• Individual - Individual

• Individual - Group

For example:

• Sibling (Individual - Individual)

• Parent/Child (Individual - Individual)

• Caretaker (Individual - Group)

• Neighbour (Group - Group)

## ID Documents

Registrants can have one or more ID Documents.

The system does not enforce uniqueness of Document ID by default. If uniqueness is required, deduplication should be performed.

ID Document types can be configured by an administrator.
