Digital gazetteer essentials

(controlled vocabulary)

•None of these elements are unique identifiers of a particular place



What's a gazetteer?

Originally (in the simplest case) setof (name, location)

– the "index" in an atlas – a "geographical dictionary" – feature labels for GIS data layers

ADL basics setof (name, type, location)

ADL extended Time-stamped names, extents, and relationships Descriptive information about names and places Merging of information about a place from multiple sources

Preferred definition

Spatial dictionary of named and typed places



Roles of gazetteers in digital libraries

Collections useful information in their own right

References canonical (official or preferred) names and locations

"Finding aids" where's this? location = gaz(name, type) what's here? (name, type) = gaz(location)



Digital libraries and gazetteers

Content + Standards + Services Communities >> domain-specific gazetteers

(local and specific knowledge) Exchange >> shared standards Protocols >> search & retrieval for distributed gazetteers

Federations "middleware" (broker) aggregates access to multiple

gazetteers

NKOS

Networked Knowledge Organization Systems/Services Informal association for the discussion of the functional and

data model for enabling knowledge organization systems (KOS), such as classification systems, thesauri, gazetteers, and ontologies, as networked interactive information services to support the description and retrieval of diverse information resources through the Internet.
