| title: Locating an Item in Place and Time | ||
| id: 318 | ||

| summary: "Use navDate together with the navPlace extension to provide geographic and temporal data" | ||
| viewers: | ||
| - Navplace Viewer | ||
| --- | ||
|
|
||
| ### Use Case | ||
|
|
||
| You have one or more IIIF resources that have a date and a location associated with each, and you would like to provide these to a client for use in the user interface. For instance, you may wish the client to provide a visualization in a timeline with an associated map, or to provide the capability to filter the set based on a date range or a bounding box on a map. The data required to meet this use case can be provided by the use of both the `navDate` and `navPlace` properties on the IIIF resources. | ||
|
|
||
| ### Implementation Notes | ||
|
|
||
| The `navDate` property, as implied by its name, allows a Manifest to identify a pertinent date associated with an IIIF resource in order to help viewers provide users with date-aware navigation. Clients are not required to make use of `navDate`, and clients that do have date-aware navigation available may not default to that navigation interface. This property is described in [Navigation by Chronology][0230] | ||
|
|
||
| The `navPlace` property is analogous to `navDate`, but provides geographic information. The value for `navPlace` is a single [GeoJSON Feature Collection](https://iiif.io/api/extension/navplace/#222-feature-collection). A Feature Collection represents an aggregation of spatially bounded areas. This property is described in [Locate a Manifest on a Web Map][0154]. | ||
|
|
||
| The `navPlace` property is not processed by the Universal Viewer or Mirador viewer at this time. | ||
|
|
||
| ### Example | ||
|
|
||
| The example consists of a [Collection](collection.json) that references five Manifests. All five Manifests contain the `navDate` and `navPlace` properties, as shown below. | ||
|
|
||
| The example can be displayed in a [custom viewer](https://mikeapp.github.io/maptime-demo/?iiif-content=https://preview.iiif.io/cookbook/0318/recipe/0318-navPlace-navDate/collection.json). In the viewer, click on the "Limit by Date Range" button to sort the objects by date. Adjust the ends of the timeline slider to filter the objects based on a date range. | ||
|
|
||
| In a more limited way, the Collection can be displayed in the Navplace viewer used elsewhere in this cookbook. This viewer will show all examples places appropriately on a map, but ignores the `navDate` data. | ||
