The Special Activiy Airspace (SAA) System Wide Information Management (SWIM) Pilot will extend the benefits of the SAA SWIM services by supporting the automated dissemination and portrayal of SAA information (including updates) to National Airspace System (NAS) stakeholders and other external users via OGC Web Services. Several use cases and supporting workflows are provided to enable understanding of the design of the pilot. The use cases involve the access, filtering and portrayal of SAA information as well as notifications of SAA updates or schedule changes to subscribed users.
The organizational concept of the SAA SWIM pilot involves coordination assistance from the Open Geospatial Consortium together with NAS stakeholders with an emphasis on airline partners’ usage of SAA information for flight dispatch and planning purposes. Stakeholders and partners are solicited to provide and deploy hardware/software as well as collaborate on the final architecture and technology design of the pilot.
Both architecture and technologies will be developed in a way to accommodate additional capabilities and stakeholders, such as exposing SAA information services to Department of Defense (DoD) systems to automate scheduling and information synchronization. The ultimate goal is to use international geospatial standards and web services to provide end-to-end information flows from DoD originators of SAA activation requests to airlines and other NAS stakeholders. Achieving that goal will lead to improved compliance, utilization, reporting and efficiency of DoD and FAA cooperation on SAA usage.
As such the objectives of the SAA SWIM Pilot are three-fold:
1-     Provide access to static and dynamic SAA information via OGC Web Services,
2-     Expose SAA information services to the NAS stakeholders, particularly airlines, to support flight dispatch and planning,
3-     Develop and exercise a standards-based Service-Oriented Architecture (SOA) that can accommodate future requirements related to automated scheduling and information synchronization with the DoD.

The Open Geospatial Consortium (OGC®) calls for participation in the OGC Web Services Shibboleth Interoperability Experiment that will advance standards for implementing federated security in transactions involving geospatial data and services.
 
This Interoperability Experiment is initiated by Cadcorp. Cadcorp is a world leader OGC compliant GIS software based in UK. Cadcorp and its partners provide digital mapping and spatial management solutions to a wide variety of organizations across the globe. Assisting in development is the European Spatial Data Infrastructure with a Best Practice Network (ESDIN) project.
 
ESDIN is a EU eContentPlus project led by EuroGeographics and aims to assist member states with implementation of the INSPIRE Directive. One of the current ESDIN activities is advancing the security, access management and privacy used in operational spatial data infrastructure (SDI) using the Shibboleth technology. This will allow establishing operational strength access control to ensure data provided is only available to legitimate government agencies.
 
The IE will demonstrate use of SAML with OGC Web Services including use of Shibboleth. Shibboleth is an open source software package released by the Internet2 Consortium based on the Security Assertion Markup Language (SAML) standard from OASIS. European National Mapping Agencies and leading European universities have been advancing the use of Shibboleth in operational SDIs as part of the activities of the Shibboleth Access Management Federation. This interoperability experiment is built on federation best practices and a previous ESDIN lead authentication Interoperability Experiment.
 
The software code and documentation, that may be used for this activity, will be made available by ESDIN on September 6th. It will facilitate participants to modify their OWS clients so they can work with Shibboleth.
 
A bird of feathers meeting will take place during the week of the OGC Technical Committee meeting in Toulouse, France, 20-23 September 2010. A virtual kickoff meeting will take place on September 30th. To finalize this activity a best practice report will be presented at the OGC Technical Committee meeting in Sydney, Australia, 29 November - 3 December.

The goal for the OGC GeoSPARQL standard is to support representing and querying geospatial data on the Semantic Web. GeoSPARQL defines a vocabulary for representing geospatial data in RDF, and it defines an extension to the SPARQL query language for processing geospatial data.

The preliminary work on a draft of the candidate standard has been completed. As soon as possible, the SWG hopes to approve a 30 day Request for Comment for the candidate standard to the OGC Technical Committee and to the public. The resulting comments will guide the GeoSPARQL SWG in the finalization of the implementation standrrd, hopefully to be ready for a final standardization vote by OGC before the end of 2011.
