bestandsconversie

Bestandsconversie, in English often referred to as file conversion, is the process of transforming digital objects from one file format to another to improve long-term accessibility, interoperability, or preservation. It is a central activity in digital preservation and data management, aimed at reducing reliance on obsolete software or hardware.

In practice, bestandsconversie is part of format migration and differs from preserving a file in its original form. The goal is to produce derivatives in stable, well-documented formats that are more likely to remain readable over time, while metadata and provenance about the original object are retained. It is one component of a broader strategy that also includes bit-preserving storage, emulation, and thorough documentation.

Common approaches include transformative (unidirectional) conversions and reversible or reversible-like workflows. The choice of target formats typically favors open, well-supported, and widely documented standards (for example PDF/A for documents, TIFF or PNG for images, WAV or FLAC for audio, and standardized video formats). The process requires careful planning to minimize information loss and to preserve essential metadata and authenticity.

A typical workflow involves assessing the original object, selecting suitable target formats, performing the conversion with validated tools, and conducting quality assurance. Provenance, technical metadata, and integrity checks (such as checksums) are recorded. Both the original and the derivative files are preserved, with documentation of the transformation process and the software used.

Standards and practices often reference the OAIS reference model, PREMIS metadata, and preservation planning guidelines. Bestandsconversie supports long-term access to digital holdings but carries risks of perceptual or informational loss if not carefully managed.
