WHERE -- PLACE Some problems with place names: - Different forms: St. Petersburg, Санкт Петербург, Saint-Pétersbourg, . . . - Multiple names: Cluj, in Romania / Roumania / Rumania, is also called Klausenburg and Kolozsvar. - Names change: Bombay became Mumbai. - Same names: 18 different places have been called Beijing. - Anachronisms: No country called Germany before 1870. - Vague, e.g. Midwest, Silicon Valley, Far East - Boundaries change: 19th century Poland; Balkans; USSR.

Slide10: 

WHERE -- Space Spaces have coordinates: latitude and longitude. . . . and a GAZETTEER links places and spaces! A gazetteer is a list of place names and also . . . says what kinds of place (Feature type): city, lake,… . . . gives latitude and longitude . . . shows when similar place names are for different places . . . brings together different names for the same place and . . . allows places to be displayed on maps.

Slide12: 

Gazetteer lists capital cities (PPLC) in box around South America.

ECAI Metadata Infrastructure WHEN Time period directory Timeline

Slide14: 

So a similar solution: A gazetteer-like Time Period Directory. Gazetteer: Place name – Type – Spatial markers (Lat & long) -- When Time Period Directory Period name – Type – Time markers (Calendar) – Where Note the symmetry. Note the connections between Where and When. A directory of 2,000 named time periods derived from LCSH Chronological subdivisions is at ecai.org/imls2004 Relationship between place names & period names

ECAI Metadata Infrastructure WHO Biographical dict. Text & images Lives involve events: WHAT: Actions – Arab invasion WHERE: Places - Ctesiphon WHEN: Times – 632CE WHO: People – Khosrau II

Slide16: 

WHEN, WHERE and WHO. Catalog records found from a time period search commonly include names of persons important at that time. Their names can be forwarded to, e.g., biographies in the Wikipedia encyclopedia.

Slide17: 

BIOG. DICT. Text TOPIC LIST Maps GAZETTEER Captions Social datasets TIME PERIOD DIRECTORY Timeline Chronology Normalize time terminology and calendar. Similarly with personal names . . . etc.

Any document, object, or performance. Any resource: Audio, Images, Texts, Numeric data, Objects, Virtual reality, Webpages Any catalog: Archives, Libraries, Museums, TV, Publishers Markup with metadata connects it to its context – and all other resources. Understanding means knowing context. Facet Vocabulary Displays WHAT Thesaurus Cross- e.g. LCSH references WHERE Gazetteer Map WHEN Period directory Timeline WHO Biograph. dict.
