Wikidata:WikiProject Historical Place

From Wikidata
Jump to: navigation, 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.

The focus of this WikiProject is first on names and boundaries.

Tasks
  • Propose a recommendation for describing change of a place in a consistent manner
  • Propose sets of properties for different historical places
  • 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?
  • Which properties are used to connect predecessors, successors, merges and splits etc?
  • How are these entities linked hierarchically to historical administrative units?
  • Christiania (Q21711493) and Oslo (Q585) is a possible example to discuss with.

Example of a single persistent item[edit]

<Add here an example of a place that remains the same item, but the properties describe change>

<Add the principle or guideline that this choice follows>

<Create an example of the properties or link to an item where this principle is used>

Example of a changing item[edit]

<Add here an example of a place that changes into another item>

<Add the principle or guideline that this choice follows>

<What properties may be used to describe the change>

<Create an example of the properties or link to an item where this principle is used>

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!
