\"CosmoCorp,\" a global conglomerate with headquarters in New York and significant operations in several Eastern European countries, is undertaking a major project to consolidate all its data repositories into a single, unified data lake. These repositories contain a mix of data, including customer records, legal documents, and research papers, with a substantial portion originating from Cyrillic-based sources. The Chief Data Officer, Anya Petrova, recognizes the critical need for consistent and accurate transliteration to ensure data integrity, searchability, and compliance with international regulations. However, different departments within CosmoCorp have historically employed varying transliteration methods, leading to significant inconsistencies and data silos. Anya is tasked with selecting a transliteration standard to be implemented across the entire organization. Considering the long-term implications for data management, legal compliance, and international collaboration, which of the following approaches would best address CosmoCorp\'s need for a unified and reliable transliteration system, ensuring seamless data integration and minimizing potential errors in cross-cultural communication and legal contexts?
