SIF Accomplishments • Development and refinement of SIF workflow process. • Identification and deployment of open source workflow system. • Design of experts database and definition of requirements for its linkage to the workflow system. • Accepted request from GEOSec to be GEOSS interoperability “help desk”: – Worked with NASA ECHO services to have them registered properly. – Based upon discussions w/ NASA and GMU, researched and decided on terms for Standards register entry associations, based on eb. RIM. • Formation of Regional Teams. • Design of SIF web presence.

SIF Goals 2009 • Automate workflow system interoperability with registries. • Refine process for review of standards and special interoperability arrangements. – Engage the Regional Teams • Outreach to make GEOSS users and participants more aware of the SIF’s role. – INSPIRE query regarding catalog service descriptions went to AIP • Deploy SIF web presence.

Registry Submission Review Process • Initial Screening – All required fields populated properly • Adherence to GEOSS Interoperability Principles – Standard is non-proprietary; – Standard is “open” meaning is that the specification is accessible by anyone. This does not preclude costs to purchase the standard; – Profiles of the standard are provided where required to make the standard specific enough for implementation; – Standard is well documented; and – Standard has support within at least one user community. • Based on the above, either the item is accepted as submitted or submitter is informed that further work is required

Registry Submission Review Process, p. 2 • Contributes to the overall GEOSS mission? – Suitable for wider use within GEOSS? Would wider adoption present any impediments to GEOSS objectives? – Applicable to communities or SBAs other than those identified? – Should the proposed item be showcased? – Should the contributor be made aware of other/similar standards? – Recommend that Contributor and/or contributor organisation play a bridging function between GEOSS components and Societal Benefit areas (SBAs)? – Inform contributor of complementary organisations wherewith linkages/partnerships may be established? – Relationship to entries in the Service & Component Registry, e. g. is the item referenced by many components and services; are there components and/or services in a similar domain that do not use the item?

Conclusion of Review Process • Outputs of the Review Process: – Recommendation in status change of item, – Feedback to contributor, – A set of proposed actions (to be ratified by SIF), – Recommendations, notifications to GEO Community, – Any additional comments for the attention of the SIF.

SIF Challenges • Getting a broader complement of committed volunteers. • Implementing a rating system for standards and special arrangements – Based on usage to indicate successful interoperability endeavors. • Making SIF the clearinghouse of interoperability issues for GEOSS.

Schedule • November 2008 – SIF workflow system operational – SIF website operational – Refinement of SIF review process • December 2008 – Engage regional teams in SIF tasks • January 2009 – Start of SIF outreach activities • February 2009 – Complete SIF review of existing registry entries • March 2009 – Automate workflow system with Standards Registry • dependent on available resources

IP 3 Status to ADC/WGISS Siri Jodha S. Khalsa Stefano Nativi

Two-way discussion on interoperability in terms of GEOSS’ broad goals and practical aspects and issues exposed in AIP How IP 3 Fits In Help w/ Interoperability Review of Special Arrangements AIP Implementation Experience SIF Mediation Capability Scenarios IP 3 Process Refinement Registries

IP 3 Accomplishments • Analysis of cross-discipline interoperability requirements based on 5 user scenarios • Implementation of a Climate Change Impacts on Biodiversity user scenario offering – An Ecological Niche Modeling server – An Ajax based client to interface the ENM server – Access to Local, Regional and Global climate change datasets (e. g. IPCC and TOPS data) – CSW-based discovery service to GBIF Species Distribution data

IP 3 Goals • Host, register and operate the IP 3 Mediator component for AIP, including: – A community (IP 3) clearinghouse Catalogue Service – Interfaces to numerous disciplinary services based upon interoperability arrangements • The IP 3 Team will participate in interoperability testing of the IP 3 Mediator with other registered components and services to assist in the realization of selected SBA scenarios • Develop and register model interoperability arrangements along with specific mediation solutions, advancing concept of “Model Web. ”

Identifying Unmet Needs • IP 3 will make recommendations where existing standards are not currently meeting the needs of the disciplines including – draft recommendations to appropriate standards developing organizations based upon the GEOSS "Special Arrangements“ and forward to SIF

IP 3 Challenges • Integrating with one or more existing portals • Engage other multidisciplinary science communities – Develop cross-disciplinary use scenarios – Implement mediation services to discover and access resources based on special arrangements • Experiment process interoperability – Workflow for scientific resources registering, discovery and access • Experiment model servers interoperability – Workflow for registering, discovering and accessing model components

Schedule • November 2008 – New cross-disciplinary use scenarios are designed – New Model resources to be registered and interfaced are recognized • February 2009 – IP 3 Clearinghouse/Mediator fully operational – Demonstration of the new cross-disciplinary use scenarios – Demonstration of the new model servers usage – Process interoperability workflow for Scientific resources is described and demonstrated. This is provided as a contribution to the GCI. • June 2009 – Additional cross-disciplinary use scenarios and mediation services

Model Interoperabililty • Simulation models are generally built in isolation and do not easily interoperate with others • Result: lost opportunities to address important questions • Barriers to interoperability are both technical and cultural • For IP 3 we will EGU GA 4/08 # 18

• knowledge is as heterogeneous as human beings; thus, "mediation" is the only way to address such domain. The technocratic approach to generate a world of "standard" components which fit in perfectly seems to be utopist and limiting.
