Building Digital Libraries from Simple Building Blocks

Metadata harvesting has been established by the Open Archives Initiative (OAI) as a viable mechanism for connecting a provider of data to a purveyor of services. The Open Digital Library (ODL) model is an emerging framework which attempts to break up the services into appropriate components based also on the basic philosophy of the OAI model. This framework has been applied to various projects and evaluated for its simplicity, extensibility and reusability to support the hypothesis that digital libraries (DLs) should be built from simple Web Service-like components instead of as monolithic software applications

Comparing Repository Types - Challenges and barriers for subject-based repositories, research repositories, national repository systems and institutional repositories in serving scholarly communication

After two decades of repository development, some conclusions may be drawn as to which type of repository and what kind of service best supports digital scholarly communication, and thus the production of new knowledge. Four types of publication repository may be distinguished, namely the subject-based repository, research repository, national repository system and institutional repository. Two important shifts in the role of repositories may be noted. With regard to content, a well-defined and high quality corpus is essential. This implies that repository services are likely to be most successful when constructed with the user and reader uppermost in mind. With regard to service, high value to specific scholarly communities is essential. This implies that repositories are likely to be most useful to scholars when they offer dedicated services supporting the production of new knowledge. Along these lines, challenges and barriers to repository development may be identified in three key dimensions: a) identification and deposit of content; b) access and use of services; and c) preservation of content and sustainability of service. An indicative comparison of challenges and barriers in some major world regions such as Europe, North America and East Asia plus Australia is offered in conclusion

Supporting personalised content management in smart health information portals

Information portals are seen as an appropriate platform for personalised healthcare and wellbeing information provision. Efficient content management is a core capability of a successful smart health information portal (SHIP) and domain expertise is a vital input to content management when it comes to matching user profiles with the appropriate resources. The rate of generation of new health-related content far exceeds the numbers that can be manually examined by domain experts for relevance to a specific topic and audience. In this paper we investigate automated content discovery as a plausible solution to this shortcoming that capitalises on the existing database of expert-endorsed content as an implicit store of knowledge to guide such a solution. We propose a novel content discovery technique based on a text analytics approach that utilises an existing content repository to acquire new and relevant content. We also highlight the contribution of this technique towards realisation of smart content management for SHIPs.<br /

Hacking Heritage: Understanding the Limits of Online Access

As cultural heritage collections become available online they carry the promise of ‘access’ – new audiences, new uses, new understandings. But access is never simply open. Limits are imposed, structures are defined, categories are created. Decisions are made about what gets digitised and why. This chapter will describe a series of experiments within online cultural heritage collections to investigate the meaning of access. What happens, for example, if we invert the usual processes of discovery and focus on records in the National Archives of Australia that have been withheld from public view? What does our history look like if we restrict our gaze only to resources that have been digitised? By manipulating the contexts of cultural heritage collections we can start to see their limits and biases. By hacking heritage we can move beyond search interfaces and image galleries to develop an understanding of what’s missing
