WS-DAI-RDF(S) ContainerAccess and ContainerIteratorAccess To provide access to particular RDF(S) resources that are RDF(S) containers, focusing on the management of the members of the container, as well as the structure of the container AltAccess To provides access to particular RDF(S) containers that are of the particular alt type * WS-DAI-RDF(S) Indirect access interfaces of WS-DAI-RDF(S) RepositoryCollectionFactory To provide access to the repositories in a collection RepositoryFactory To provide access to the repository content ListFactory To provide access to the contents of an RDF collection ContainerFactory: To provide access to the contents of a container. * WS-DAI-RDF(S) ontology specification * Open Cloud Computing Interfacein Data Management-Related Setups OCCI With fast growing of cloud computing This demands for standards to ensure interoperability and avoid vendor lock-in The OCCI family of specifications Open Cloud Computing Interface developed for the deployment of infrastructure Clouds it can also be used in different service and deployment models * OCCI * OCCI Motivation for Standards Interoperability How two services can inter-operate on the fly. This demands a standardized API and protocol Integration How a service provider can bring together different technologies and interconnect them within his domain Portability In comparison with interoperability, there is no direct connection between the service provider. This demands that there are standardized data formats which providers can understand * OCCI Innovation Standards can be a driver for innovation as well as widely adopted innovations can demand standards Reusability This can be seen on two levels The reuse of (legacy) codes through basic standardized APIs The reuse of the standard itself in different fields * OCCI The core meta-model for OCCI imposes a general means of handling general resources providing semantics for defining the type of a giv
