EPA’s System of RegistriesEPA’s System of Registries• A series of registries that help manage key
metadata, data standards, business objects, and terminology
• Some are authority files– Chemicals and substances– Facilities– XML Schema/Tags
• EPA Data Registry – 11179 metadata reg. • Newly added Environmental Terminology
System and Services (ETSS) primarily addresses topical terminology

Why Terminology? Why Terminology?
• So that we know what we mean
– Key business terms and acronyms
• So we can find stuff
– Indexing, cataloging, keyword management
• Others are counting on us
– Emergency response
– Other Federal Gov’t
– International efforts Gary Larson – The Far Side
What Is the ETSS?What Is the ETSS?• Search & Discovery Portal – a tool to find, use,
and download terminology• Terminology Management – a repository of
important terms with user interfaces for creation, storage, maintenance, harmonization, and distribution of various types of terminology
• Automated Services – Web interfaces and services to allow exchanges of terminologies with Agency and partner systems
• Collaborative Stewardship – a framework for the development of vocabulary-specific workflows and processes
Key ETSS CustomersKey ETSS Customers• Human Customers
– EPA vocabulary developers like the Web Taxonomy Project– Policy makers defining terms in regulations– System developers selecting XML tags and defining data
elements– Program managers and researchers seeking terms and
glossaries perhaps via the portal – Non-EPA vocabulary developers interested in environmental
terms– People trying to use terms and definitions consistently– Stakeholders, partners and the public
• System Customers– Search engines – to expand searches or provide the basis for
taxonomies or folders– Enterprise content management – source of value domains
and controlled vocabularies– Other systems that use pick lists

ETSS ImplementationETSS ImplementationWhere We’re At• Synaptica KMS software from Dow Jones was selected• Editorial system in production as of early April• Over 250 vocabularies and 11,000 terms migrated from TRS• Training sessions held for editors• New Web Taxonomy created and maintained• Read-only interface for staff and public under development Next Steps• Implement read-only interface for EPA staff, public and partners• Establish governance and workflow for vocabulary development• Integrate with SOR and other systems• Develop strategy for moving toward a concept-based system
What is Concept Management?What is Concept Management?• Organizing terms around core concepts in a business, domain or
enterprise
• Goals:*– Articulate clear and concise meanings of business domain
concepts– Achieve a shared understanding of the concepts among relevant
stakeholders, and– Guard the stability of a concept’s meaning during system
development• Major activities:*
– Scoping the environment of discourse– Concept specification, integration and enforcement

A Practical and Theoretical Perspective” 2003.

Concept Management Concept Management and the Semantic Weband the Semantic Web
The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.
It is all about:
• Managing concepts• More explicit meaning• Structure and standards• Tools and infrastructure
Where do we want to go?Where do we want to go?• ETSS supports the ability to connect multiple
vocabularies:– Put an umbrella concept system over all the
vocabularies to which the individual terms can be linked
– Increase the links between terms, including across vocabularies
– Create richer relationships between terms– Continue to add definitions– Develop tools for comparing terms and
definitions
