püsiformaat

Püsiformaat refers to a digital file format that is designed for long-term preservation and accessibility. The primary goal of püsiformaat is to ensure that digital content remains readable and usable far into the future, even as technology evolves and older systems become obsolete. This is achieved through several key characteristics.

First, püsiformaat typically relies on open, well-documented, and widely adopted standards. This openness reduces reliance on proprietary software or hardware that may cease to exist. Common examples include plain text formats like TXT, structured formats like XML, and widely supported image formats like TIFF.

Second, püsiformaat prioritizes simplicity and avoids complex or unstable features. Highly compressed or proprietary formats may offer advantages in storage or speed but can become problematic for long-term access if the necessary decompression tools are no longer available.

Third, integrity and authenticity are crucial. Mechanisms for verifying the content's original state, such as checksums or digital signatures, are often incorporated or recommended to ensure that the file has not been altered over time.

The development and selection of püsiformaat are often guided by archival principles and best practices, aiming to mitigate digital obsolescence and ensure that cultural heritage, scientific data, and other valuable digital assets can be accessed and understood by future generations. Institutions involved in digital preservation, such as archives and libraries, play a significant role in defining and promoting these formats.
