• OMN-lifecycle Ontology: Overview

• Example 1: Testbed A - TBA (Wired PLE-like)

• Example 2: Testbed B - TBB (Wireless NETMODE-like) • OMN-wireless-ontology

3

Ontology for describing the whole life cycle of resource/service management in the federation.

Omn-lifecycle Ontology

• A collection of resources and/or services and the relationships between them, as requested by an experimenter.

Request

• Provides all resources and services offered to experimenters by the testbedOffering

4

Omn-lifecycle Ontology

• Describes the collection of resources and/or services provisioned to an experimenter.

Manifest

The reservation of a Resource/Service/Topology is modeled using the Reservation class and the hasReservation object property of OMN.

• A collection of resources and/or services reserved and scheduled to be provisioned to the experimenter at a future point in time.

Example TBA - The Unbound Request: SPARQL QueryNode instance is selected

Exclusive use of the node

Excludes nodes already allocated/provisioned during the requested period
