Top web preservation program's solutions in facing technical challenges

The present study aims to verify web preservation projects and programs in order to explore their preferred solutions in tackling the technical challenges. A documentary method was used to identify and analyze web-preservation-related literature, including papers, handbooks, web sites and documents. The programs’ persons in charge were also questioned. Besides, top web preservation programs and projects were identified and studied using Google search, as well as the program's interfaces and documents, related directories and literature. After verifying and filtering the programs, 61 top ones were remained to be studied. The web preservation technical challenges can be categorized into several categories including the components to be preserved, the preservation strategy; the versions & editions to be preserved; metadata; metadata types; metadata production methods; searching & browsing services and modes; indexing services; classification & cataloging; harvesting, access & indexing software; and preservation model. The operational programs were found to choose various solutions to overcome the technical challenges. However, there still remains a wide range of problems hindering an ideal implementation.
