When registering a dataset on data.overheid.nl you can choose from various file formats. These file formats are selected on the basis of the DCAT model. The most common formats are explained in the table below.
FORMAT
Explanation
Atom
XML based format similar to .rss. It is designed as a universal standard for personal content and weblogs.
JSON
This standard format is used for storing simple data and objects. The text can be read by humans and is based on javascript.
OGC: WMS
WMS is used in many GEO datasets. Querying a web service format can cause problems in the web browser. A help tool such as ArcGis or QGis is therefore advisable when opening the data.
OGC: WFS
WFS is used in many GEO datasets. Querying a web service format can cause problems in the web browser. A help tool such as ArcGis or QGis is therefore advisable when opening the data.
GML
Geography Markup Language (GML) is the geographic file exchange format. It defines XML coding for transferring and storing all kinds of geo-information, such as geometry, topography, coverages and sensor data. GML can be used for file exchange but also within web services such as WFS.
KML
Keyhole Markup Language (KML) is an XML based standard markup language for geographic data. It is recognised as an ISO standard and is often used in combination with Google Maps.
TXT
TXT formats are text formats. They are intended to exchange textual data.
ZIP
A ZIP is a folder containing multiple documents.
CSV
Comma Separated Values (CSV). File with data separated by commas. CSV is often used to exchange data.
HTML
HTML is a web page that is displayed in a web browser. The HTML source code is parsed by the web browser and is usually not seen by the user.
XML
XML is a data file that uses tags to define objects and object attributes; formatted just like an HTML. XML files are a standard way of storing and transferring data between programs and on the internet. Since they are formatted as text documents they can be edited by a simple word processor.
