## Overview of Community Invitations

For a generic overview of all community functionality, see the Community Functionality Overview.

Invitations are messages sent to users to invite them to join a community. Any community may have invitations, but they are necessary for communities which are not public and have public registration disabled-- the only way a user can join such a community is to receive an invitation.

Invitations may be sent out over any messaging system, such as email, instant messenger, portal framework notifications, or any other messaging system by implementing a provided SPI. Email-based and notification-based implementations of this SPI are provided.

When a user receives an invitation, they can go to the community registration page and register to get a membership in the community. Invitations may contain a set of membership capabilities, so that when the user redeems the invitation for a membership they are automatically given the capabilities included in the invitation.

The `Invitation` object stores the following information:

Attribute | Type | Description
--- | --- | ---
attributes | `String` names and values | Arbitrary attributes may be stored in the invitation by application code when the invitation is created. These attributes are not used by the portal community framework, so applications may use them as they see fit.
communityID | `CommunityDefinitionId` | The ID of the community the invitation is for.
creationDate | `Timestamp` | The time and date the invitation was created.
expirationDate | `Timestamp` | The time and date the invitation will expire. If `null`, the invitation will never expire.
fromWlsUserName | `String` | The user name of the user that sent the invitation.
payload | `String` | A textual message to the person being invited to the community.
status | `InvitationStatus` | The status of the invitation. When an invitation is first sent, its status is `sent`. If nothing is done with the invitation before the specified expiration date, the status is set to `expired`. If the user receiving the invitation chooses to accept it and join the community, the status is set to `accepted`; if the user chooses not to join the community the status may be set to `rejected`. If an administrator chooses to revoke the invitation before the user accepts it the status may be set to `revoked`.
capabilities | `Collection`<`MembershipCapability`> | A set of community capabilities to give to the user if they choose to join the community.
inviteeAddress | `String` | A string representation of the address (email, IM, etc.) that the invitation was sent to. This can be `null` if the wlsUserName is not `null`.
inviteeId | `InviteeId` | A unique ID for the invitation.
validationText | `String` | A String token which can act as an authentication mechanism for the invitation. If the invitation is sent to a person who does not currently have a user account (a WLS user name) on the system, this token can be sent along with the invitation message (email, IM, etc.) in the URL to the community registration page for the community the user is invited to. The validation text can be used to indicate that the person attempting to redeem this Invitation object received the invitation message (email, IM, etc.). Validation text is generated by implementations of the `InvitationValidationTextGenerator` interface, so it may be implemented in any manner deemed necessary.
wlsUserName | `String` | The WLS user name of the person being invited to join the community, if they already have an account on the system, or `null` if the user does not have an account on the system or if this is unknown at the time the invitation is created. If this value is `null`, the inviteeAddress may not be `null`.

The `CommunityInvitationHelper` object contains convenience methods for retrieving and sending invitations.
