How can this image of a

Sassanian seal from the 5th

century C.E. be located in a

collection?

ECAI Metadata Infrastructure

Facet Authority control Special display tools

WHERE Gazetteer Mape.g. NGA

WHEN Time period directory Timelinee.g. HumanSaga

WHO Biographical dict. Text & imagese.g. Who’s Who

WHAT Thesaurus Syndetic structure

Library mechanism for

WHERE Gazetteer Map

e.g. NGA

Data location is now shown in a map generated

by using latitude longitude markup

Gazetteer shows

alternate names

Place name is tied to

coordinates

WHEN Time period directory Timeline

e.g. HumanSaga

Directory of

“named time

periods

TimeMap with GIS

draws a map with the

polygons for empires.

Instruction for this

procedure is contained in the named

time periods

Multiple maps can be created for comparison

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

WHO Biographical dict. Text & images

e.g. Who’s Who

Lives involve multiple:• Places - Ctesiphon• Times – 632CE• Events – Arab invasion• Other people – Khosrau II

WHEN and Who. These named time periods are derived from Library of Congress catalog subject headings and so can be used for catalog searching which finds books on topics important for that time period.

Named Time Periods located through Library of Congress

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.
