ISO 19005 is an international standard that specifies the requirements for the long-term preservation of electronic documents. It focuses on ensuring that digital files remain accessible and usable over time, regardless of changes in technology or software. This standard is particularly important for organizations that need to retain documents for legal, regulatory, or historical reasons. The standard outlines a framework for using PDF/A, a specialized version of the Portable Document Format (PDF) designed for archiving. By adhering to ISO 19005, organizations can ensure that their electronic documents are stored in a way that maintains their integrity and readability for future generations.
