Paper : Cost Model for Digital Preservation
نویسندگان
چکیده
Digital Preservation Testbed was a practical research project with the overall goal of investigating options to secure sustained accessibility to authentic archival records over the long-term, by carrying out experiments in a controlled and secure environment. This allowed the project to ascertain the effects of undertaken preservation action on different archival records. Testbed researched three different approaches to long-term digital preservation: migration, XML and emulation (more specific: the UVC [Universal Virtual Computer] approach). Not only the effectiveness of each approach has been evaluated, but also their limitations, application potential and costs. Experiments have taken place on four different record types: text documents, spreadsheets, emails and databases of different size, complexity and nature.

متن کاملA cost model for small scale automated digital preservation archives
Assessing the costs of preserving a digital data collection in the long term is a challenging task. The lifecycle costs consist of several cost factors. Some of them are difficult to identify and to break down. In this paper we present a cost model especially for small scale automated digital preservation software system. The cost model allows institutions with limited expertise in data curatio...
متن کاملJoint pricing, inventory, and preservation decisions for deteriorating items with stochastic demand and promotional efforts
This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...
متن کاملDigital Library Issues Arising from Earth Science Data
NASA, NOAA, and USGS collections of Earth science data are large, federated, and have active user communities and collections. Our experience raises five categories of issues for digital librarianship: Organization of the data in the collections is not well-described by text-based categorization principles Metadata organization for these data is not well-described by Dublin Core and needs atten...
