1. What are XML Web Services?

• XML is a standard for preserving and
  communicating information encoding, tagging,
  and internationalizing.
• Web Services provide communication between
  applications running on different Web servers
  that will bring the Internet to its new level.
• XML Web Services is the technology underlying the
  new programs you have just heard about
• Exchange Network (NEIEN)
• Central Data Exchange (CDX)
• Alpha and Beta Nodes
• XML Web Services is what everyone in EPA and the
  States should know something about.

Future National Environmental Information
Exchange Network

• The Blueprint Team recommends the exclusive use
  of XML as the common basic interchange language
  for data flows. (page 24)
• The Blueprint Team believes that simplified
  versions of the tools (e-commerce servers),
  technologies (XML), and security levels being
  developed and rapidly embraced by the private
  sector can be applied to the business of
  environmental agencies.
• The Knowledge Transfer Action Team of the Interim
  Network Steering Group is developing an XML
  Training proposal for managers and technical
  staff.
• Blueprint for a National Environmental Exchange
  Network, National Blueprint Team, Document

• Written agreement and funding to deliver XML
  data, XML meta data, and P2P Web services.
• Access to XML asset management tools and training
  (e.g. Canon/Developer).

Level 6 Xml-ization of Databases and Embedding
and/or Linking to Data Standards, Metadata, and
Data Quality Information

• Enterprise XML Data and Meta Data
• Embedding Data Standards, Metadata, and Data
  Quality in XML Data
• Data Dictionaries and Data Element Harmonization
• Re-design and Re-publishing of the EDR
• Enterprise Metadata Integration Using XML Web
  Services GIS, EIMS, and EDR
• XML-ization of EnviroFacts and Other
  Environmental Databases

23
XML Data and Metadata Architecture

• XML data and meta data architectures are
  connected.
• From a Resource Perspective, meta data is either
  external to or embedded within the data.
• From a Client Perspective, meta data is either
  centralized or distributed.
• Peer-to-peer approaches are needed in an more
  distributed environment to simultaneously query,
  discover, and aggregate the results locally.
