SIF Status to ADC Co-Chairs Siri Jodha S. Khalsa Steve Browdy

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 ebRIM. 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.

SIF Challenges Agreement within GEO on basic terms and scope. –Does SIF “adjudicate”? –Status of Standards vs. Special Arrangements? Gain a broader complement of committed volunteers. Implement a rating system for standards and special arrangements usage to indicate successful interoperability endeavors. Making SIF the clearinghouse of interoperability issues for GEOSS.

How IP3 Fits In AIP IP3 SIF Implementation Experience Help w/ Interoperability Registries Mediation Capability Process Refinement Review of Special Arrangements Two-way discussion on interoperability in terms of GEOSS’ broad goals and practical aspects and issues exposed in AIP Scenarios

IP3 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

IP3 Goals Host, register and operate the IP3 Mediator component for AIP, including: –A community (IP3) clearinghouse Catalogue Service –Interfaces to numerous disciplinary services based upon interoperability arrangements The IP3 Team will participate in interoperability testing of the IP3 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 IP3 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

IP3 Challenges Integrating with one or more existing portals

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.
