Enterprise Architecture is evolving to Business Transformation to demonstrate value in actually changing the business processes of organizations. Data Architecture is evolving to a more comprehensive activity to support business transformation in actually doing model-driven data applications for organizations. Data Architecture means looking at all of the information (data) in the enterprise in a structured fashion, even the “unstructured data”.

Data Architecture means working to make it easier to bring key information about the same real-world entities and transactions together. Our initial objectives were to see if this Web 2.0 Wiki can be useful in bringing about collaboration across EPA Metadata and Data Architecture. A longer range goal is to see if this Web 2.0 Wiki could be used as an Enterprise Metadata Management and Data Application Development Tool (e.g. data and metadata mashups).

It has also been suggested that EPA's National Dialogue be transformed from "tell us how to improve access to show how how you are using EPA data" by opening up Wikis for public posting of EPA data stories and uploading of file attachments, creating incentives for participation and interaction, and learning what we can improve upon. This could produce a Wikipedia-type compilation of EPA data use and reuse! Show me the data! (like the famous line "Show me the money" from the movie Jerry Maguire)

Ultimately, data quality is a function of usage, not collection or processing…the more you use data the better it gets, the less you use data the worse it is…data that is never used cannot be correct. The same is true with data models, if you don’t use them you can’t be sure they’re any good. (Source: Ken Orr, Data Architecture for Business Architects.) The EPA Statistics Users Group and the EPA Quality Staff are among the most experienced EPA data users (see below).


  • Make Data Architecture is analogous to Product Architecture: How do we design our data so that we can produce more and more data products faster and cheaper. (Source: Ken Orr, Data Architecture for Business Architects.)
  • Help people use EPA data to collaborate and built applications.
  • Bring together the following: Traditional data modeling (David Hay); Ontologies (John Sowa and Arun Majumdar); and Semantic Web (Jim Hendler and Dean Allemang) using Web 2.0/3.0 Wikis for bookkeeping  and collaboration on all of this that would have the added advantage of attracting younger people to this area.
  • Take the enterprise view that all the Segment Architectures gives us the “ontology” (context) for doing the data modeling (which the Segment Data Architects should do for their segments and then share them with all the others), and then we can collaboration – semantic Web enable this using the Web 2.0/3.0 Wikis and other tools. 

Structure and Interface:

Concept Defintion Specific Example Comments
Federal Enterprise Architecture Data Reference Model The Data Reference Model (DRM) describes, at an aggregate level, the data and information supporting government program and business line operations. This model enables agencies to describe the types of interaction and exchanges occurring between the Federal government and citizens. Web 2.0 Wiki  Continue to be the leading implementor.
Federal Geospatial Data Sharing An EPA / DOI / USDA / NOAA Community of Practice around Federal Geospatial Data Sharing has been established to explore and document ways in which information is currently being shared across these enterprises, percieved barriers to data flows, with a goal to establish enhanced geospatial data sharing capabilities among the federal community in the future.

Web 2.0 A term describing the trend in the use of World Wide Web technology and web design that aims to enhance creativity, information sharing, and, most notably, collaboration among users. These concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, wikis, blogs, and folksonomies. (Source: Wikipedia)

Indicator A numerical value derived from actual measurements of a stressor, state or ambient condition, exposure, or human health or ecological condition over a specified geographic domain, whose trends over time represent or draw attention to underlying trends in the condition of the environment.

Statistics Users Group The EPA statisticians that are widely scattered throughout the offices of the EPA, supporting our air, water, pesticide, toxics, or research programs. Examples of what they do include designing surveys for a variety of situations, such as national aquatic assessments or requirements of emergency coordinators; attributing risk to environmental stressors; developing experimental designs to assess genetically modified organisms; predicting ozone levels; recalling cars for excess emissions; designing and implementing a motor vehicle tampering survey; reviewing correlations between blood lead and environmental lead; modeling occurrence of bacteria; and evaluating airport de-icing fluids.

Quality Systems Manage the quality of its environmental data collection, generation, and use to ensure that our environmental data are of sufficient quantity and quality to support the data's intended use. Under the EPA Quality System, EPA organizations develop and implement supporting quality systems. Similar specifications may also apply to contractors, grantees, and other recipients of financial assistance from EPA. (Source: EPA Web Page)

LandView has its roots in the CAMEO software (Computer-Aided Management of Emergency Operations). CAMEO was developed by the EPA and the NOAA to facilitate the implementation of the Emergency Planning and Community Right-to-Know Act. This far-reaching law requires communities to develop emergency response plans addressing chemical hazards and to make available to the public information on chemical hazards in the community.

This product contains both database management software and mapping software used in the CAMEO system to create a simple computer mapping system involving two programs - MARPLOT® and LandView.

The MARPLOT mapping program allows users to map Census 2000 legal and statistical areas, EPA Envirofact sites, and USGS Geographic Names Information (GNIS) features.

The LandView database system allows users to retrieve Census 2000 demographic and housing data, EPA Envirofacts data and USGS GNIS information. The GNIS contains over 1.2 million records which show the official federally recognized geographic names for all known places, features, and areas in the United States that are identified by a proper name. Source: LandView Web Page
