What is a resource?
A dCal resource is a dCal account that is used to schedule an object, a group of objects, or the activities for a group of calendar users. You can schedule a resource the same way you schedule an individual, by adding (inviting) it to a meeting. For more information on resources, see Using dCal resources.
In Web terminology, a resource is “anything addressable via a URL.” However, Dublin Core implementations are not necessarily Web-based. Dublin Core metadata can be used to describe any kind of resource – including various collections of documents and non-electronic forms of media such as a museum or library archive.
