As notified on Oslo Børs's Delta pages 26 June, Oslo Børs will make a minor change to the top level element of all XML reference data files. The go-live date will be Tuesday 3 September.
The "validDate" attribute of the top level element of each file will be modified to contain the trading date for which the file is valid (i.e. the same date which is also included in the file name). Previously this attribute contained the file creation date. However, the file creation date can be found in the "generated" attribute of the same element. There is no change to the "generated" attribute.
This change has been in effect in the customer test environment (CDS) since 27 June. The change will take effect in production from Tuesday 3 September, i.e. the first set of files in the new format can be downloaded in the evening of 2 September.
Please note this change only impacts the XML files. There is no change to the CSV files.
