What concept does the "3-legged stool" refer to in the context of digital archiving?

The "3-legged stool" concept in the context of digital archiving refers to the idea that three critical components must be balanced to create a stable digital preservation environment. In this metaphor, each leg of the stool represents one of these essential resources necessary for effective digital preservation.

When focusing on this concept, it is essential to recognize that preserving digital content is not solely about technology or hardware; it involves a triad of resources that include technology, people (human resources), and policies (strategic frameworks or guidelines). Each of these "legs" must be strong and well-supported for the overall preservation initiative to succeed. Without adequate support from all three components, the entire preservation effort can become unstable, analogous to how a stool would topple over if one leg were weak or missing.

This understanding underscores the multifaceted nature of digital preservation and emphasizes the need for a comprehensive approach that integrates various forms of support, whether they be technological infrastructures, organizational frameworks, or skilled personnel. Thus, recognizing the balance of these three essential resources reflects a sophisticated understanding of what is required to achieve effective digital long-term preservation.
