These findings are based on a place name – feature type – location gazetteer which also includes place-making events and their dates.

What Else Might Gazetteers Do?

•Historical network analysis: a map from Janet Abu Lughod’s Before European Hegemony. World historians use trade and travel maps like this to identify connection points and core-periphery structures, but not yet in a data-rich and digital mode.What if we also include relationships among places (for

instance the order in which they appear along an itinerary) and a few more attributes?

OWTRAD (Old World Trade)

•Sixty-five temporally and spatially referenced comma-delimited files organized according by travel routes and nodes. •Author Matthew Ciolek created the datasets by hand from published works of scholarship, which he cites. •Thinking about world history as a scholarly field, this is a world history gazetteer.

Student Travel Narrative Project

• Michael Curry, “Toward a Geography of a World Without Maps: Lessons from Ptolemy and Postal Codes.”

• Three modes of thinking about the world:– Choros (names and

regions)– Topos (travels, itineraries,

and relationships)– Geos (mathematically

oriented maps of continuous space)

More Attributes to Consider• Names:

– Their origin, etymology, and semantics may be meaningful and worth including in a database.

– What to include? Yi-fu Tuan: “the number of places in the world is infinite.”

– Language and politics. Doreen Massey: “history is the meeting up of places.”

• Feature types: are domain specific. Integrating them between gazetteers requires some ontology.

• Georeferences: Locations can be vague or even mythical, but the places exist in a text and in reference to other places.

• Sources: historical gazetteers need to reference historical sources. Palestine 1946
