CMS 01_0171_igs- 5 Proposed SECOORA Enterprise Architecture Framework n Purpose – Provide guidance to the Working Groups and Subgroups to ensure that SECORRA development activities consider the context of IOOS, IEOS, GOOS, and GEOSS architectural frameworks Use what we need If we decide to go in a different direction, we do so with full understanding of the cost, the benefits and the implications n Activities – Develop an EA Framework for SECOORA – Vet framework through Working Groups – Publish/maintain SECOORA EA Framework Document n Constraints – Top-down guidance incomplete and not single source NOAA is currently normalizing the results from two IOOS Conceptual Design Studies GEOSS Secretariat is currently investigating options for developing Reference Architectures for GEOSS – Bottom-up driver required consensus across stakeholders We’re not there yet n Purpose – Provide guidance to the Working Groups and Subgroups to ensure that SECORRA development activities consider the context of IOOS, IEOS, GOOS, and GEOSS architectural frameworks Use what we need If we decide to go in a different direction, we do so with full understanding of the cost, the benefits and the implications n Activities – Develop an EA Framework for SECOORA – Vet framework through Working Groups – Publish/maintain SECOORA EA Framework Document n Constraints – Top-down guidance incomplete and not single source NOAA is currently normalizing the results from two IOOS Conceptual Design Studies GEOSS Secretariat is currently investigating options for developing Reference Architectures for GEOSS – Bottom-up driver required consensus across stakeholders We’re not there yet

CMS 01_0171_igs- 7 GEOSS Architecture Framework n Assets. A GEOSS asset is any data stream, system, application, product or service that has utility or value to any potential GEOSS user. This definition is extremely broad and expansive – by design. We do not wish to constrain creativity or innovation in the ways in which GEOSS can create value to society. n Adapters. Adapters are the software that integrate assets into the GEOSS Enterprise. Adapters expose products or services to the Enterprise without impacting the systems or applications that they connect. Adapters are also used to connect users into the Enterprise. n Services Infrastructure. A GEOSS Services Infrastructure provides the “Backplane” or place where adapters physically integrate assets into the enterprise. A Service Infrastructure provides a common Asset Registry as well as the underlying communication, security and workflow services for the Enterprise. Replication of these services at multiple sites provides Enterprise-wide interoperability. n Assets.

CMS 01_0171_igs- 10 GEOSS Asset Compliance n All GEOSS assets need to be registered with in a node of the GEOSS Asset Registry. n The required set of attributes for this registry have not yet been defined, but it will need to go beyond a typical Federal Geospatial Data Committee (FGDC) profile. – All data and information products will need to include Machine readable description of product format Semantic characterization (ontology) Full detailed history of relevant milestones with the complete product life cycle (full provenance) Characterization of quality – All applications and services will need to include: Full characterization of the service interface Full detailed history of relevant milestones with the complete application life cycle (full provenance) Characterization of its Service Level Agreement (SLA) – Availability – Business Rules or Constraints – Quality n All GEOSS assets need to be registered with in a node of the GEOSS Asset Registry. n The required set of attributes for this registry have not yet been defined, but it will need to go beyond a typical Federal Geospatial Data Committee (FGDC) profile. – All data and information products will need to include Machine readable description of product format Semantic characterization (ontology) Full detailed history of relevant milestones with the complete product life cycle (full provenance) Characterization of quality – All applications and services will need to include: Full characterization of the service interface Full detailed history of relevant milestones with the complete application life cycle (full provenance) Characterization of its Service Level Agreement (SLA) – Availability – Business Rules or Constraints – Quality

CMS 01_0171_igs- 11 GEOSS Adapter Compliance n All GEOSS Adapters should be registered in the GEOSS Asset Registry and placed into a software reuse library. n An item in the reuse library shall consist of – Documented source code – Full detailed history of relevant milestones with the complete adapter life cycle (full provenance) – Test procedures – Relevant Use Cases n All GEOSS Adapters should be registered in the GEOSS Asset Registry and placed into a software reuse library. n An item in the reuse library shall consist of – Documented source code – Full detailed history of relevant milestones with the complete adapter life cycle (full provenance) – Test procedures – Relevant Use Cases

CMS 01_0171_igs- 12 GEOSS Service Infrastructure Compliance n The evolution towards GEOSS will be facilitated by the development of a basic services infrastructure that can be replicated across the enterprise. n Replication provides a degree of local autonomy in terms of what assets need to be brought to bear for a particular national, regional or thematic community of interest; yet, because the service infrastructure is common, it promotes interoperability across the enterprise. n Replication provides a set of “common services” n Components of this basic service infrastructure include: – GEOSS Asset Registry (single system distributed across multiple sites) – Semantic Services (ability to create, update and map ontologies) – Discovery/Access Services (ability to plug in tailored portlets) – Security Services (ability to provide authentication, authorization) – Workflow Services (ability to chain together applications) – Development Services (support the development of adapters, portlets) n The evolution towards GEOSS will be facilitated by the development of a basic services infrastructure that can be replicated across the enterprise. n Replication provides a degree of local autonomy in terms of what assets need to be brought to bear for a particular national, regional or thematic community of interest; yet, because the service infrastructure is common, it promotes interoperability across the enterprise. n Replication provides a set of “common services” n Components of this basic service infrastructure include: – GEOSS Asset Registry (single system distributed across multiple sites) – Semantic Services (ability to create, update and map ontologies) – Discovery/Access Services (ability to plug in tailored portlets) – Security Services (ability to provide authentication, authorization) – Workflow Services (ability to chain together applications) – Development Services (support the development of adapters, portlets)
