  2. Community Knowledge • information preservation, refers to the ability to understand the rendered object at any time, i.e., to be able to understand its content by understanding the terms, concepts or other information that appears in it, by placing it in its correct context • Another important observation that can be made here is that the need for preservation can appear in both space and time dimensions. • The “space” dimension refers to the fact that different people have different background knowledge and, consequently, may have trouble understanding each other’s documents (e.g., an astronomer may have trouble understanding a scientific paper on computer software). • Similarly, the “time” dimension refers to the fact that different people in different times Terminology and Wish List for a Formal Theory of Preservation

  6. Provenance • A contextmaybe a rich object that hasdescriptions about its properties (such as provenances) and relations to other contexts. • the provenanceof a context, including the aspects of temporal (when), spatial (where), agent (who), casual (why) and other properties. Context Representation for the Semantic Web

  7. Reference • Barwise and Seligman (1992) use natural regularities to study the role of context in categorization. An example regularity from Seligman (1993) is, “Swans are white.” This is atypical natural regularity in the sense that it is both reliable and fallible. Natural regularities are reliable because they are needed to explain successful representation, knowledge, truth, and correct reference. They are fallible because they are needed to account for misinterpretation, error, false statements, and defeasible reference .
