Question 1 of 30
The \"Starlight Financial Archive,\" an OAIS compliant repository, contains a significant collection of financial records dating back to the early 1990s. A substantial portion of these records are denominated in Deutsche Mark (DEM), the currency of Germany before its replacement by the Euro (EUR) in 1999/2002. Considering the requirements of ISO 14721:2012 regarding the long-term preservation of understandable information, and acknowledging the role of ISO 4217 in standardizing currency codes, how should the archive manage the DEM-denominated records to ensure their continued accessibility and interpretability for future users who may not be familiar with the historical currency? Assume that relevant legal and regulatory frameworks require the preservation of original financial records, including their original currency denominations, for audit and compliance purposes. The archive must balance the need for preservation with the need for understandability in a contemporary context. The archive is also subject to regulations that mandate the use of standardized currency codes for all financial reporting, even for historical data.
Retain the original DEM currency code in the archived records, add descriptive metadata indicating that DEM was the former currency of Germany and has been replaced by EUR, and include a reliable conversion factor (e.g., the official fixed conversion rate at the time of Euro adoption) for converting DEM to EUR.
Convert all DEM values to EUR using historical exchange rates at the time of each transaction, replace the DEM currency code with EUR in the archived records, and discard the original DEM currency code to simplify future reporting and analysis.
Rely on external currency conversion services to dynamically convert DEM values to EUR or other contemporary currencies upon user request, without permanently altering the original archived records or adding any specific metadata about the currency change.
Ignore the currency conversion issue altogether, preserve the DEM-denominated records as they are without any modifications or additional metadata, and assume that future users will be able to independently research and understand the historical context of the Deutsche Mark.
