A digital archive, adhering to the OAIS framework, is preparing to ingest a collection of historical scientific datasets. These datasets are complex, featuring proprietary data formats and intricate relationships between different data files. To ensure these datasets remain accessible and understandable for researchers decades from now, what critical component within the Archival Information Package (AIP) is primarily responsible for providing the necessary context and technical specifications to interpret and render the raw data, thereby safeguarding against technological obsolescence and ensuring long-term usability?
