1. Background
  • 1.1 February 27 - 28 Region 3/Mid-Atlantic
    States Information Management Meeting,
    Philadelphia, PA.
  • XML Web Services Training and Presentation of
    Region 3 and Chesapeake Bay Program Pilot-Part 1.
  • Region 3 Pilot Team Formed.
  • 1.2 March 13 - 14 OEI National Meeting, Chicago,
    IL.
  • XML Web Services Training and Discussion of
    Region 5 Pilot Projects (Interagency wetlands
    data integration).
  • 1.3 April 11 Chesapeake Bay Program Information
    Management Subcommittee, Annapolis, MD.
  • Presentation of Region 3 and Chesapeake Bay
    Program Pilot-Part 2.
  • PASDA (Pennsylvania Spatial Data Access) Interest
    in Participating.
  • 1.4 June 10-13 EPA-State TRG/Node 1.0 Meeting,
    Philadelphia, PA.
  • Region 3 Discussion of Work Statement and
    Demonstration of the Stage 1 Prototype.

2. Information Design and Architecture
  • Requirements
  • Use XML content network technology to integrate
    the content over the Region 3 network and the
    Internet and to update it.
  • Start with a subset of the content to build a
    working prototype (Stage 2-see Slide 9) within 60
    days and then add more content to it to make it
    an EPA portal to be demonstrated at the Second
    OEI National Meeting in November 2002.

2. Information Design and Architecture
  • Menu
  • Watershed Restoration
  • Sensitive Populations
  • Enhancing Responsible Development
  • Explanation
  • Short descriptions of each menu item with an
    icon.
  • A template will be provided for each content
    source with a link between it and the data
    sources.
  • The templates were developed by a business
    process and need to be implemented to automate
    that recurrent business process (yearly or so).

3. Proposed Work Statement
  • 1. EPA Region 3 will provide a server running
    Windows NT Service Pack 6a connected to the
    internet and LAN (s) that meet the minimum
    requirements for running NXT3 3.3 and reach the
    required content.
  • 2. NextPage will install the NXT3 software and
    EPA Region 3 will identify the location (URLs,
    mapped drives, etc) for the content to be
    integrated and provide samples for prototyping.
  • 3. EPA Region 3 will provide directions for the
    hierarchical system of folders and interface for
    accessing the distributed content to NextPage
    along with the work flow specification for
    updating each piece of content.
  • 4. NextPage will install the working prototype on
    the Region 3 server and demonstrate the
    capabilities, especially, the implementation of
    the workflow for the updating of content from
    distributed locations (nodes) and instantaneous
    refresh of reports.
  • 5. EPA Region 3 will provide a list of
    refinements to the working prototype to NextPage.
  • 6. NextPage will deliver the refinement to the
    working prototype for Region 3.

4. Demonstration of Stage 1 Prototype
  • Prototype in three stages
  • Stage 1 Manual aggregation and repurposing of
    content using the NextPage LivePublish at one
    non-EPA location can demonstrate live updating.
  • Stage 2 Network aggregation of content and
    repurposing using the NextPage NXT 3 at one EPA
    server location.
  • Stage 3. Network integration of content using the
    NextPage NXT 3 at multiple EPA server locations
    where necessary.

5. Some Next Steps
  • 5.1 Clarify the work flow process.
  • 5.2. Refine the Work Statement and decide on the
    60 day schedule.
  • 5.3 Demonstrate Stage 1 Prototype to John
    Armstead and present the Work Statement.
  • 5.4 Process the Subcontract for NextPage.
  • 5.5 Prepare the EPA Region 3 Server for NextPage
    to work on.
  • 5.6 Track the EPA Geospatial Metadata and Data
    Network Pilots in Region 3 and 5 (see next slide).

5. Some Next Steps EPA Geospatial Metadata and
Data Network
  • Use of GML (XML for geospatial data) is our CIOs
    priority and is described in the Geospatial
    Blueprint A Strategic Plan for the EPA
    Geospatial Program (May 2002 draft).
  • The Regions and Program Offices have begun to
    pilot the use of XML for geospatial metadata and
    the use of GML/OWS (Open Web Services) for the
    integration of diverse and distributed geospatial
    data.
  • Vendors are starting to release new products that
    include the OpenGIS Consortiums specifications
    for geospatial interoperability (e.g. Ionic
    Enterprise-see next slide).
  • A pilot XML/GML content network for integrating
    distributed geospatial metadata and data is in
    process for EPA Region 3 (see next slide).
