Location Awareness Services for WebSphere® Premises Server allows you to use containment relationships to track items. For example, a containment relationship makes it easier to track items being shipped together, such as on a pallet.
You can dissolve containment relationships by editing the properties of the class to remove the container classification.
Using containers also allows you to visualize the location of all contained items, even if they are not tagged or their tags are not visible to a tag reader. In this case, when the container moves, Location Awareness Services for WebSphere Premises Server assumes the contained items also move. Also, if a container enters or leaves a zone, Location Awareness Services for WebSphere Premises Server assumes all contained items also enter or leave the zone and all rules apply to both the container and contained items. Rules can also be defined to prevent items from being removed from a container or added to a container.
It is important to note that the last reported position of a container and the position of its content can differ. This might be the case if the items in the container and the container itself are actively tagged. If contained items are removed from the container's location, you might want to remove the containment relationship and track all items separately. If the tags of the contained items are not visible or are read from a different tag reader than that of the container, the position coordinates might be read as being located outside of the container. In this case, you might want to define business rules that cause the position of the tagged items in the container to be ignored.
