Moving between Contexts

Any action is performed in a particular context. So what does it mean to do the ‘same’ thing in a different context? There is no simple answer to this question , it depends on the interpretation of the operation and even then may be ambiguous. This is not a purely theoretical problem, but occurs in practical computationalproblems.Thispaperexaminesthisissuelookingatthreedifferent problems:multi-userundo,distributedupdateandthesimultaneousdevelopment of a document in multiple formats. In each case, we find formal rules which any sensible translation must obey. We also see that dynamic pointers, a generic specification and implementation concept defined in previous work, can be used to generate default translation rules which suffice in many circumstances. This is because dynamic pointers can themselves be seen as a translation of location information between different contexts.
