XML Web Services Training and Discussions

• Brand Niemann, US EPA and Chair, CIO Councils
  XML Web Services Working Group

Instructions

• I think your FEDWEB Fall 02 presentation, "The
  Promise of XML Web Services for Government,"
  would be perfect for the intended audience.
• Some things additional to your "Promise of
  XML..." presentation that will be especially
  interesting to us
• How can we best prepare for OMB's various e-gov
  initiatives, especially the HHS-led e-grants
  effort?
• We're currently an Oracle 9i shop. What's been
  your experience/is your view vis a vis Oracle's
  support for XML and utility in an XML-based
  environment? Are there other tools (like Tamino
  XML Server) that we should consider?
• What are some of the "best practices" that other
  agencies have adopted in their use/integration of
  XML, and how might some of those best practices
  map back to DOLETA's mission?

Simplified Use Case E-Forms

• Design-time
• Identify the data elements in the form(s),
  harmonize the elements (promoting reuse wherever
  possible) and create an XML Schema for each form
  (XML Collaborator).
• Store the XML Schema in an XML registry (XML
  Collaborator), so that others can access the
  information necessary to
• Create e-forms and paper forms (GIDS).
• Create mapping(s) to information systems, such as
  relational databases, object-oriented databases,
  and flat files (MetaBase Modeler).

• Runtime
• Present user with a form to be filled out. User
  populates the form and submits it (GIDS).
• Create XML from the submitted data (GIDS) that
  complies with the schema registered in the XML
  registry (XML Collaborator) and populate
  information systems with the data gathered from
  the user (MetaMatrix Server).

Basic Working Implementation of the Standards
WSDL Document

• 1. Client queries registry to locate service.
• 2. Registry refers client to WSDL document.
• 3. Client accesses WSDL document.
• 4. WSDL provides data to interact with Web
  service.
• 5. Client sends SOAP-message request.
• 6. Web service returns SOAP-message response.
