Preface

• We have already built hundreds of Web Services
  nodes using a standards-compliant platform that
  provides data integration with EPA content and
  interoperability with non-EPA content, now we can
  see how we can build hundreds of portlets using a
  new open standards-based platform.
• October 17th on the upcoming October 19th
  Collaborative Expedition Workshop Demonstration
  of Building Enterprise Architecture through Web
  Services for Remote Portlets (WSRP) in Sample EPA
  Regional Portal.
• This is now being called grid computing.

  accesses Web content about environmental health
  and safety using a natural language interface
  based on the VoiceXML standard.
• Commercialized as GeoResponse.Com which notifies
  emergency operators about emergency hot spot
  regions and automatically looks up the telephone
  numbers within those regions and automates
  automatic delivery of important information over
  the phone.
• A distributed XML Web Service across multiples
  companies that offers free, secure, user-specific
  data pilots using a subset of your data (GIS and
  phone numbers).
• Demonstration site at http//www.georesponse.com.

  Roles-based usage (e.g., CIO, Manager,
  Developer).
• First Federated Repositories FEA-Compliant
  Reference Models Web Site Launched with Nearly
  200 High-Quality Components Using the Logidex
  Asset Center (follows more a "push model" than
  the "pull model" of Core.Gov)

Pilot Summary Technical Solution Options
Increasing levels of support for the strategic
management of ITIM initiatives maturation by
automating all levels of SDA usage, real-time
metrics collection, and enabling management of
actual inventories.

4.4 LogicLibrary Federated Repositories
Note that the deployable .ear file is now
accessible this is an artifact configured as
private (which can be done on an asset-by-asset
basis by the Asset Publisher or automatically
through publish templates), which means the asset
user cannot access the artifact until asset
acquisition is complete.

4.5 Unicorn Semantic Information Management

• The leader in implementation of Semantic
  Information Management (SMI) for structured

  Ontology Problem from the First Annual Semantic
  Technologies for eGov Conference at the White
  House Conference Center, last September 8, 2003,
  which the EPA CIOs Chief of Staff, Bill Sonntag,
  submitted.
• Deals with the shortcomings of the traditional
  XML Schema and ETL (Extract-Transform-Load)
  methods which have been found to be too brittle
  in enterprise applications (break easily when
  something is changed).

• Run queries across sources
• Analyze and visualize (using 3rd party tools)

• What does this mean? Where did it come from?

• Discover data sources
• Impact analysis
• Create schemas

• Manage repository
• Manage ontology model collaboratively
• Semantic mapping

31
4.5 Unicorn Semantic Information Management
Semantic Mapping

• Map each data asset once only as a spoke to
  Ontology Model hub
• Formal semantic mappings capture meaning of data
  in formal machine-readable form
• Flexibility of Mapping
• Map all assets relational, XML, legacy, etc. to
  same model
• Productive mapping in two stages groups (e.g.
  tables) and fields (e.g. columns)
• Attach conditions to mapping
