The Geoprocessing Community announces a new Web Processing Service release! The 52°North WPS 3.1.0 contains some WPS4R improvements, several bugfixes and results of the Code Sprint with USGS/CIDA and TU Dresden. The 3.1.0 version includes the WPS Client API 3.1.0. In addition, the WPS Process Development Kit was updated to version 3.1.0.

New features include:

• Improved stability and performance
• Clean handling of POSTed requests:
  • Requests are now limited to 128Mb (DoS check).
  • Added support for POSTed mimetype of "application/x-www-form-urlencoded" with parameter "request" and the value containing the xml payload (not part of WPS specification but "courtesy" functionality for demos usingweb-forms)
• Clean results servlet
• New HTTP response headers:
  • "Content-Disposition" for all non-xml reponse types (if response parsed in browser, this will force a "Save as..." dialog) "Content-Length" when available from database XML now reformated to remove identation unless response is requested as attachment (in which case, it's added)
  • Added support for "attachment" GET KVP argument for explicit use of "Content-Disposition" header
  • For "xml" mimetypes, added explicit headers required to disable aggressive caching in IE
• Support for xs:anyURI

New developer features are:

• End-to-End functional testing
• Refactored base classes from implementation in Server and IO modules
• Clean handling of ExecuteResponse handling and Database updated
• Support for implementation of Java algorithm with annotations DescribeProcess derived from annotations
• Automated unbinding of inputs and binding of outputs
• Improved thread safety and concurrency behavior
• Analyzed dependencies:
  • Updated old dependencies,
  • Removed unused dependencies.
• Improved database:
  • Added ability to report response Content-Length to IDatabase
  • Added ability to store and return requests to IDatabase
  • Added ability to gzip stored data to FlatFileDatabase
  • Added 7 day expiration/file wipe to responses stored in FlatFileDatabase
