Comparative Research On Encapsulation Strategies For Electronic Records

Electronic records management requires to guarantee the authenticity, integrity and effectiveness of electronic records. The essence of electronic records management content is the collection, management and utilization of electronic records and their metadata. By relating, embedding and belonging to the electronic records and their data, electronic records encapsulation realizes the self-contained, self-describing and self-certified of electronic records and since guarantees the electronic records evidential function and promotes the long-term preservation of electronic records.The principles of electronic records encapsulation are simple and practical, safe and reliable, and unified standard. Different electronic records encapsulation strategies have different encapsulation patterns and utility generated. The essay takes the electronic records encapsulation strategy as the research objects, comprehensively analyzes the similarities and differences of typical encapsulation strategies, and puts forward the encapsulation strategy evaluate index system. The index system consists of two levels of indicators. The first level indicators include availability, adaptability, safety and convenience; the second level indicators include the availability of standards, data and tools; the adaptability of objects, systems and characters; the safety of data, technologies and systems; the convenience of structure, grammar and data relations.Finally the essay points out that several measures could be taken in practice from the following aspects:firstly, is improving METS encapsulation strategy from the perspective of security; secondly, is improving DA/T48from the perspective of adaptability; finally, is developing new electronic records encapsulation strategy based on deep understanding of the theory combined with electronic records encapsulation selection indicators.
