Releases By Date


OpenFEMA API framework version 8.0 has been released. In addition to general bug fixes and performance improvements, version 8.0 of the API framework addresses the following:

  • Invalid/unsupported query string parameters will no longer be accepted. An error will be returned indicating the invalid parameter.
  • Changes to the handling of $filter argument data types. The values provided for a filter argument must be quoted or not quoted according to the field data type. The new framework logic will not allow strings for Booleans - only a Boolean value or a number corresponding to a Boolean (i.e., true/false 0/1) will be accepted. Similarly, numeric values like fiscal years will fail if expressed as a string instead of a number.
  • Enhanced error messaging when query strings are invalid.
  • Fixed an error related to the JSONA file format.
  • Introduced JSONL as a new file format which will be particularly useful for streaming data.
  • The returned field order is now specified by a metadata element. Prior to this version, fields were returned in no particular order. Your processes may be affected if they expected a specific field order. One possible workaround is to use the $select parameter to specify the field order you prefer.
