Go over purpose and objective given by Myra
Explain the SOA mechanism
SOA-based ESG architecture
Experience ESG through its functionalities, and
Some future plans

3. Introduction to SOA Services are registered in catalog;
SOA is an architecture to build information systems
Service is the key of SOA, service can be built from functional components of an information system.
SOA provides a mechanism to support the rapid prototyping of applications by leveraging the flexibility of services
Services are registered in catalog;
Catalogs broker registered Services;
Clients integrate application logic to access Services.

4. ESG Architecture

5. ESG Functionality: Publishing
ESG supports OGC Catalog transactions (v2.0)
ESG supports FGDC and ISO metadata standards
ebRIM schema facilitates adding resource types
EST supports the publishing of online resources, such as web services and document, into the catalog
The resources will be registered in the catalog by recording relevant information in ISO or FGDC metadata format
ESG could access online resources and extract as much information as it can
Once a resources is published or harvested by ESG, an ESG search/discovery will be able to find the resource
ebRIM: ebXML Registry Information Model

6. ESG Functionality: Discovering
Provides an intuitive user interface;
ESG also serves XML queries according to the OGC Catalog Interface (2.0).
Before we do the demo, we should keep in mind that we don’t control the QoS of services provided by others:
Server maybe offline,
service url maybe changed after registration,
service layer names may be changed after registration
Search through ESG can 1) locate places, 2) discovery data services, 3) discovery web services, and 4) discovery other resources;
Get a place name from the audience and search.
Search “World” to find data/web services, build a TM image based jurisdiction application.

7. ESG Client The collaboration function can be sharing files, images, or
Setup a discussing thread through JForm

8. Collaborations NASA Applied Science Program
ESIP and its Earth Information Exchange
GEOSS Applications
Other Federal Partners
When the phase II of ESG is accomplished, we will work with our federal and non-profit organizations, to
support their purposes & objectives, and
advance ESG/Geoscience Interoperability
