Why OGC?
• Open Geospatial Consortium• www.opengeospatial.org
• ~80% of all data collected or produced by the human race ~80% of all data collected or produced by the human race is geospatially referencedis geospatially referenced
• “Helping the World to Communicate Geographically”• Any type of geospatial data• Anything that goes on a map
• A Few Current OGC Standards• Web Map Server (WMS)• Web Feature Server (WFS)• Web Coverage Server (WCS)• Catalog Service for Web (CSW)
• Commercialization of these standards• ESRI (www.esri.com)

OGC-OGF Common Objective
• Promote international standardization with the goal of providing distributed data processing capabilities for geospatial data users in a way that is:• TransparentTransparent -- the users do not have to be aware of the
exact data and computing resources they are using or the details about doing so,
• InteroperableInteroperable -- the data and computing resources can come from different sites, and
• ScalableScalable -- the same user model can service small computing tasks that can be done locally, as well as large computing tasks that require massive remote platforms.

Basic Terms of the MOU
• Renewable one-year periods• Automatically renewed unless one party provided
written notification three months in advance of non-renewal
• OGC and OGF exchange memberships for key collaboration members• Key collaboration members have full access to
both organization’s documents• OGC has members-only web site areas

Potential OGC-OGF Joint Projects 1
• Integrate OGC's Web Processing Service (WPS) with a range of "back-end" processing environments• WPS embodies a simple model• User sends data, retrieves results, or leaves on
server• Wide range of implementations possible
• Web 2.0, basic web services, local/national grid infrastructures

Potential OGC-OGF Joint Projects 2
• Integration of WPS with workflow management tools• Multiple WPS calls may necessary to produce the
desired data products• Workloads managed by scripting languages,
compiled code, or by workflow management engines
• Swift• Simple API for Grid Applications (SAGA)• Workflow engines
DAGMan, Pegasus, Kepler, Taverna, and Triana, just to name a few

Potential OGC-OGF Joint Projects 3
• Integration of OGC Federated Catalogues and Data Repositories with grid data movement tools• HTTP as the transport is certainly possible• Byte-IO, GridFTP, others possible• Need for secure, third-party transfers?

The Real Goal of this Workshop
• The MOU items are a point of departure
• Get motivated people together
• Identify what people really need to do
• Get efforts snowballing between meetings
• Engage key stakeholders and potential adopters from the get-go
