This is a test.

There are multiples files to show how a "dataset" can have multiple "resources" (files).
In this test:

• the PDF is a very simple page
• the ODS (LibreOffice Calc)
• and CSV (delimited-text) are spreadsheets with just 3 lines and 2 columns, just enough on to test the Table preview (table with filter/ordering options) and the Graph preview (using the column view with the first column as X axis and second column as Y axis)
• World Populated places: point map layer (with preview)
• World countries as polygons: only the GeoJSON in CSV can offer a preview but it does not work in this case as the polygons are too complex

This description itself is in the Markdown format, which provides simple formatting.
