LWS resource — an HTTP resource as defined in [[[RFC9110]]] which supports the read operations defined by the Linked Web Storage Protocol.
Following [[[RFC9110]]], this specification "does not limit the nature of a [LWS] resource; it merely defines an interface that might be used to interact with [LWS] resources." [[RFC9110]]

storage — a set of hierarchically organized HTTP resources whose lifecycle is managed by the conventions described by the Linked Web Storage Protocol. A storage is described by a storage description resource which references a collection of services that provide affordances over those resources.

storage description — an LWS resource that enumerates and describes the storage root along with services and capabilities of a storage. Its representation conforms to the storage description data model.
- storage root — a container at the root of a containment hierarchy of a storage. The storage root is the only LWS resource that does not have a parent in the LWS containment hierarchy nor a principal resource.
