WMO Codes Registry


Overview

AvXML 1.0 Release Candidate 2 provides a BETA deployment of the WMO Codes Registry. Its primary purpose is to support the new conjoint WMO / ICAO Aviation XML standard by ensuring that authoritative terms from WMO technical regulation - most notably WMO No. 306 Manual on Codes - are available as web-accessible resources that can be referenced from XML data products.

In its current form, the Registry is sparsely populated and does not reflect the version history of changes applied by WMO. However, future iterations of this Registry are expected to increase the scope of code-tables that are published here, to implement historical change history thus providing access to previous definitions of codes and to implement multi-lingual content in the official WMO languages.

The WMO Codes Registry is set to be operationally deployed at http://codes.wmo.int once the BETA is completed. Please note that the URIs for terms published at http://test.wmocodes.info will not be maintained once the WMO Codes Registry is operational deployed to its permanent location http://codes.wmo.int.

When assessing AvXML 1.0 Release Candidate 2, any resources with HTTP URIs that refer to the http://codes.wmo.int sub-domain may not resolve. In such a case, please amend the resource URI such that the http://test.wmocodes.info subdomain is used. For example: if reviewing the term "Slush" from BUFR Code-table 0 20 086 "Runway deposits", the URI http://codes.wmo.int/bufr4/codeflag/0-20-086/6 should be amended to http://test.wmocodes.info/bufr4/codeflag/0-20-086/6.

More information regarding the implementation and behaviour of the WMO Codes Registry can be found at the github wiki for the registry software implementation project.
