CKAN's resource page can provide a preview of the resource's data if it is of
an appropriate format. If the data is available through the CKAN DataStore API, or if the data is a csv or xls file; then Recline's Data Explorer is used. If the data is
another webpage; a google doc; or an image; then it is embedded in an iframe
for viewing. Or if the data is text-like, then it's raw contents are
displayed.
The Recline Data Explorer provides a rich, queryable view of the data. The data can be filtered, faceted, graphed and mapped. Furthermore, the grid, graph or map can then be embedded into your own site using the Embed button, and copying the provided html snippet into your webpage.
The relevant code for setting up the data viewer is found in application.js.
All resources available through the DataStore API are
available for viewing through the Data Explorer. using recline's
elasticsearch backend. If the datastore is not available, and the filetype
is normalized to csv or xls, then a dataproxy is used to attempt to view
the data (using recline's dataproxy backend).
If a resource is viewable through the Data Explorer, then it is also embeddable
in third-party web pages. /dataset/{name}/resource/{resource_id}/embed
provides a stripped-down page containing the data explorer. The data
explorer's state is passed through using the url's query parameters.
