Taxonomy A Definition

• What do we mean by Taxonomy1?
• Taxonomy (from Greek taxis meaning arrangement or
  division and nomos meaning law) is the science of
  classification according to a pre-determined
  system, with the resulting catalog used to
  provide a conceptual framework for discussion,
  analysis, or information retrieval
• What makes a good Taxonomy?
• Separates elements of a group into subgroups that
  are mutually exclusive, unambiguous, and taken
  together, include all possibilities
• Should be simple, easy to remember, and easy to
  use

Taxonomies and UDDI

• UDDI Taxonomies
• Are the classification lists or systems used for
  the published services
• Services may belong to many taxonomies
• By default the UDDI registry comes with 60
  taxonomies
• Dun Bradstreet (DB) Data Universal Numbering
  System (DUNS)
• Universal Standard Product and Service
  Classification (Product Taxonomy)
• Should reflect the service consumers agenda
• May need different taxonomies for different user
  groups
• Internal users may find services using known
  lines of service
• Public or Partner users may need a more generic
  nomenclature

Taxonomies and UDDI (Contd)

• EPA UDDI Taxonomies should be EPA-centric
• Two classification schemes are being proposed
• EPA Organizational Structure
• Expert EPA users fully familiar with who provides
  what services
• Environmental Interests
• Geared toward non-expert users
• Based upon the EPAs Terminology Reference System
  (TRS)
• TRS has been used to generate a keyword list to
  support the searching capabilities of the
  Environmental Data Registry (EDR) and can provide
  keyword generation capabilities for other Agency
  Web resources, i.e., UDDI
• Uses EPA Controlled Vocabulary (Version 2.7.7
  rev. 1/4/05)

Wrap-up and Closure

• Next Steps
• Identify and remove irrelevant out-of-box
  taxonomies
• Install EPA-specific taxonomies
• Map Existing UDDI Services, etc., to new
  taxonomies
