Wikidata:WikiProject Historical Place

From Wikidata
Jump to navigation Jump to search

The goal of this WikiProject is to discuss a recommendation for describing change of a place over time.

Historical names and boundaries of places[edit]

Boundaries of administrative entities change over time. Areas are united, split, relocated or terminated. The names of places vary over time and in different languages. They are related to the changes in administrative borders as well as dependent on context, dialect, regime etc.

Tasks
  • Record current best practises
  • Identify challenging questions
  • Create necessary missing properties
  • Create pilot imports

Change over time[edit]

Add the results of discussion here, discuss on the talk page or the Wikidata-wide project chat!

A sequence of items vs. changing properties of one item[edit]

How long does a place remain the same item, and when is a new item required?

Examples of a single persistent item[edit]

  • Further fuzziness can be defined using the date property's precision.
  • Examples needed

Toponyms[edit]

  • Names in different languages, contexts, administration, script systems
  • Change of names over time and in relation to boundary or administrative changes.
  • Which datatypes and properties are used.

Questions[edit]

  1. Should place names be modeled as a property of a place or as separate items, either Q-items or L-items for lexical entries?
  2. Are place names in the scope of the Wikidata project. Current guidelines here: Wikidata:Lexicographical data/Notability#Proper Nouns

Properties for places[edit]

  • Select which features are in the scope of this project
  • List the key properties for each type of place feature and how change is expressed
  • Which WikiProjects should be connected with each feature?
  • What external expertise is available?
  • Identify missing properties. Note: Data type geographic shape is pending for the time being.

Generic, authority control[edit]

There are hundreds of identifiers marking geographic places. Here's a list of all Wikidata properties for authority control about places.

Pilots[edit]

There are several datasets that are ready to be imported or are already being imported to Wikidata. List them here to make referencing them easier. Note the source and the Wikidata destination. Make remarks about decisions that were needed or need to be solved for the import to happen.

You can also introduce a dataset and ask for community discussion about importing it.

Resources: Historical Gazetteers[edit]

Add any resources you will find a useful reference or a future import. If a non-open source has been added, please make a note!
