Some points of view of conceptual model for gazetteerECAI Gazetteer Meeting in Taipei Ya-ning Chen Computing Centre, Academia Sinica 21 August, 2001
Purpose of this conceptual model • To define common objectives for ECAI gazetteer, such as a content standard, information sharing and interchange. • To clarify requirements for fields of content standard based on a variety of attributes, such as gazetteer, time, functionality, GIS representation, and so on.
Gazetteer Is composed of Is with Place Name and Type Is located at Location Is embodied in Map Is represented by GIS
Place Name Primary Name Variant Name ADL Primary/Variant Name Etymology Language Pronunciation Transliterlation Historical Note Beginning Date Ending Date TWN 地名名稱/別稱/現舊地名 地名意義 語言別 地名發音/錄音 地名發音拼寫/注音或羅馬 命名族群 地名沿革文歷史簡述 年代_起 年代_迄
Place Spatial Location Location Adminstrative Location Spatial Location ADL longitude latitude west/east/south/north bounding coordinate Spatial Location TWN 緯度 經度 地圖標示 相關位置
Place Spatial Location Location Adminstrative Location Administrative Location ADL Address City State or Province Country Administrative Location TWN 所屬縣市 鄉鎮市區 村里
Place Location Map A, B, …. MAP TWN 圖名圖號 比例尺
Place Location Map A, B, …. Map A - 1:50000 GIS Map B - 1:25000 The same place is represented by different maps in GIS.
Gazetteer Is composed of Name authority, Lang., Etymology, History, etc. Place and Name Is located at Functionality Location Spatial, Admin., etc. Is embodied in Map Is represented by GIS
Gazetteer Is composed of Place Time Is located at Location Is embodied in Map Is represented by GIS
At different times Place Location A Location B Map A Map B GIS Peiking in Yuan Dynasty Peiking in Ching Dynasty The same place name across different times is represented by different maps in GIS, for instance, Peiking.
Gazetteer Is composed of Place Functionality Time Is located at Location Is embodied in Map Is represented by GIS
Issue What kind of categories/themes and related fields should be included for each BOX (such as gazetteer, place, location) under this conceptual model?
Issue - example • Place and NameBesides variant names, language, etymology, and history, do we have other requirements for PLACE and NAME? Such as how to distinguish the same name for different place and location? • LocationBesides the requirements for spatial and administrative location, do we have other requirement for LOCATION? Such as population, and so on.
