In order to validate the completeness of the data procurement via interfaces implemented by third parties (independent of these interfaces), the master data stock supplied by the Federal Network Agency relevant to the customer's area with regard to locations, (power generation and other) units and power plants are determined and made available in form of CSV files.
At the time the project was being carried out, the database of the market master data register of the Federal Network Agency comprised 175 differently structured UTF-16-coded XML files with a total size of around 22GB. This data is recoded to UTF-8 and filtered with awk scripts for data relevant to the customer and analyzed with regard to their relationships between locations, units and systems. The results are provided as CSV data in a way that is suitable for comparison with existing productive data.
