“…Existence of unique identifiers for the digital object and every part of it is also important to ensure preservation and easy access. Possible support of digital object typing, as denoted in (Saidis et al, 2006), that provide the manipulation and behavior of objects of the same type in a uniform manner 2. Collections and relations support.…”

The last decade a great number of digital library and digital repository systems have been developed and published as open-source software. The variety of available software systems is a factor of confusion when an organization is planning to build a repository infrastructure to host its collections. To simplify the decision process five widely used open-source repository software systems are compared, namely DSpace, Fedora, Greenstone, EPrints and Invenio. In addition to the comparison of these software systems and their characteristics' description, we propose the most suitable systems for different cases of digital collections. Using five collection paradigms that represent case studies of different content and functionality, an organization can be directed to select a repository software matching its criteria.

DOLAR: virtualizing heterogeneous information spaces to support their expansion

Users expect applications to successfully cope with the expansion of information as necessitated by the continuous inclusion of novel types of content. Given that such content may originate from ‘not‐seen thus far’ data collections and/or data sources, the challenging issue is to achieve the return of investment on existing services, adapting to new information without changing existing business‐logic implementation. To address this need, we introduce DOLAR (Data Object Language And Runtime), a service‐neutral framework which virtualizes the information space to avoid invasive, time‐consuming, and expensive source‐code extensions that frequently break applications. Specifically, DOLAR automates the introduction of new business‐logic objects in terms of the proposed virtual ‘content objects’. Such user‐specified virtual objects align to storage artifacts and help realize uniform ‘store‐to‐user’ data flows atop heterogeneous sources, while offering the reverse ‘user‐to‐store’ flows with identical effectiveness and ease of use. In addition, the suggested virtual object composition schemes help decouple business logic from any content origin, storage and/or structural details, allowing applications to support novel types of items without modifying their service provisions. We expect that content‐rich applications will benefit from our approach and demonstrate how DOLAR has assisted in the cost‐effective development and gradual expansion of a production‐quality digital library. Experimentation shows that our approach imposes minimal overheads and DOLAR‐based applications scale as well as any underlying datastore(s). Copyright © 2011 John Wiley & Sons, Ltd.

“…A similar approach is given by Saidis et al [27] as Digital Object Prototypes (DOPs) that has constituent components as files, metadata, behaviours and relationships. A DOP is a digital object type definition that provides a detailed specification of its constituent parts and behaviours.…”

In this paper, we discuss long-term digital preservation from an information perspective, rather than the predominant approaches; the Archival and the Technocratic Approach. Information lives longer than people, tools (software) and organizations live. The Information Continuum Model provides support for this standpoint. However, we find that there exists no concept to support practical action in preservation from the information perspective. Existing concepts as information object, digital object, preservation object, electronic record, information package and significant properties are context dependent and focus on the object to be preserved, rather than preservation of information. Consequently, they are not suitable for realizing the information perspective in long-term digital preservation. The concept of Digital Information Preservation Object is therefore introduced and a tentative definition of the concept is presented.
