Groups are the generic name given to the collection of data. Each folder/document in the tree in the left pane is a group. A group that contains other groups appears like a folder. If the group does not contain other groups it looks like a document.

A group has a comment, some information about it's type, a series of track points, a number of waypoints and a number of child groups. None of this information is required. It could contain only track points, or only waypoints. Also, it does not have to contain any track points or waypoints or child groups.

A group is part of a trip. A trip is likely to have many legs, each leg will be a group containing the track points and any waypoints for display.

Clicking on Create will create a new group under the selected group. The new group will be called NewGroup.

Selecting a group and clicking Delete Link will remove that group and all groups below it from the tree. The button is called Delete Link because groups are generally treated as links. That is, dragging and dropping groups does not create a copy of the group, it creates a link to the group. In the same way that a URL for a web site is just a reference to the web site, not a copy of the web site. Dragging and dropping groups just makes a reference to the original group and not a copy of it.

Groups now have permissions. This gives the owner of the information control over who can edit or update their information. For some applications it may be useful for friends/family to update trip information. Permissions can be granted for this.

There are different types of groups, they are listed below.

Leg - a list of trip points will make up one leg of a trip.

Object - the vehicle/person going on the trip. This is the object that is displayed moving across the screen. Objects would normally have a number of leg groups below them.

Event - a list of object associated with a particular event. For example, a party is an event. People could add their journey to go to that event below the event group. Thus clicking on the event group would show all people attending the event, their trip to get to the event and consequently their planned arrival/departure times. This is a simple way to get an idea of the number of attendees to an event as well as when it is likely to be busy. It is also little effort for the event organiser as the attendees will update their own information; much easier than receiving lots of emails and trying to track attendees on a spreadsheet.

List - a list of events. Lists are most useful for clubs. They can list all coming (and past) events for that club. Attending events from other clubs is easy, just drag/drop the existing event from the other club to your list. Simple.
