Extensible Markup Language (known by the acronym XML) is a widely used and easily implemented method of exchanging data between disparate computer systems. The ShakeCast System receives ShakeMap information in XML from the USGS web server and uses XML to communicate all kinds of information between ShakeCast servers:
- Data about ShakeCast Servers and the ShakeCast software itself
- Data about events (earthquakes) and products (data files) available on the network
- Status information that helps the administrators of ShakeCast servers tell if their network is running smoothly
JavaScript Object Notation (JSON) is a text-based open standard designed for human-readable data. ShakeCast V3 adopts JSON as an alternative to the XML data for exchange of earthquake information. Specifically, the V3 system receives the USGS earthquake feed in the format ofgeographic data structures (GeoJSON) in order to retrieve selected earthquake products beyond ShakeMaps. The ShakeCast system also provides its own JSON data, primarily for the purpose of web presentations and for persistent data storage.
All locally generated XML and JSON files are stored in earthquake specific directory as cached content to be used primarily by the ShakeCast web server. This Section documents the ShakeCast XML and JSON file formats.
ShakeMap RSS Feed XML
RSS, which stands for “Really Simple Syndication” (sometimes called Rich Site Summary), has been adopted by news services, weblogs, and other online information services to send content to subscribers. After subscribing to an RSS feed, you will be notified when new content is available without having to visit the web site. The USGS ShakeMap RSS data feed contains
