E N D
DFC Vision • Build collaboration environment • Sharing of data, information, and knowledge • Form national data cyberinfrastructure • Federation of existing data management systems • Support reproducible data-driven research • Encapsulate knowledge within shared workflows • Enable student participation in research • Policy-controlled analysis of “live” data Compute Resources – HPC centers, institutional clusters DFC Collaboration Environment – Data Grid NEW Community Resources – Repository, Catalog
Data Driven Science and Engineering • Plant biology – the iPlant Collaborative • Enable collaborative research across existing data repositories • Cognitive science – the Temporal Dynamics of Learning Center • Manage research data, apply IRB policies • Social Science – the Odum Institute • Integrate policy-based data management with the existing Dataverse repository Collaboration Environments • Oceanography – Ocean Observatory Initiative • Archiving climatic data records from real-time sensor data streams • Engineering – CIBER-U • Engineering Digital Library: Curating civil engineering data, materials data, archaeology data, student training materials • Hydrology - EarthCube • Automating hydrology research workflows (data retrieval, transformation, analysis)
Challenges • Federated national data cyberinfrastructure • Existing projects have web services, data repositories, digital libraries, archives, processing pipelines, science portals • What are the interoperability mechanisms needed to enable federation of existing resources?

Federation Approach • Use middleware to implement unifying name spaces for: • Users Single sign-on • Collections Directories, workflow, time series • Objects Files, soft links, workflows • Storage systems Cloud, tape, file systems, objects • Metadata Provenance, description, state • PoliciesManagement, assessment • Micro-services Procedures, interactions DFC - CNI

National Infrastructure Approach • Build national data cyberinfrastructure prototype • Support multiple science and engineering domains by loosely couplingtheir existing infrastructure with a collaboration environment • Develop generic interoperability framework • Define the generic infrastructure needed for the national infrastructure to manage knowledge as well as data and information • Define interoperability mechanisms • Support access across the disparate types of infrastructurein common use • Define domain specific extensions • Support three levels: technical interoperability, project level policy, and end user usage requirements

Interoperability Mechanisms • Drivers • Encapsulate knowledge to support your operations at the remote repository: partial I/O, parsing of formats, manipulation of data structures • Authentication, format, storage • Micro-services • Encapsulate knowledge needed to interact with an external system or with a data set using the remote protocol • Data access, external workflows, semantics, messaging • Policies • Encapsulate knowledge needed for management functions • Federation control, administrative tasks, validation checks
Assertion • Three basic types of interoperability mechanisms are sufficient for assembling national data cyberinfrastructure • Example: Linked software defined networks to data grids • From an iRODS data grid, controlled the selection of three disjoint network paths for optimizing data transport by adding appropriate policy enforcement points and micro-services • Expect functionality currently in data grid middleware to migrate into network middleware
