Prototyping Digital Libraries Handling Heterogeneous Data Sources - An ETANA-DL Case StudyRavindranathan, Unnikrishnan 06 May 2004 (has links)
Information systems used in archaeological research have several needs that can be summarized as follows: interoperability among diverse, heterogeneous systems, making information available without significant delay, providing a sustainable approach to long-term preservation of data, and providing a suite of services to users of the system. In this thesis, we describe how digital library techniques can be employed to provide solutions to these problems and describe our experiences in creating a prototype for ETANA-DL. ETANA-DL is a model-based, componentized, extensible, archaeological Digital Library that manages complex information sources using the client-server paradigm of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). We have designed and developed the prototype system with the following main goals: 1) to achieve information sharing between different heterogeneous archaeological systems, 2) to make primary archaeological data rapidly available to users, 3) to provide useful services to users of the DL, 4) to elicit requirements that users of the system will have beyond the services that it supports, and 5) to provide a sustainable solution to long-term preservation of valuable archaeological data. Consequently, we describe our approach to handling heterogeneous archaeological information from disparate sources; suggest an architecture for ETANA-DL, to be validated through prototyping; and show that given a pool of components that implement common DL services, a prototype DL can be rapidly created that supports several useful services over integrated data. Further, and most fundamentally, we note that understanding complex information systems is a difficult task. Finally, therefore, we describe our efforts to model complex archaeological information systems using the 5S framework, and show how we have used the resulting partial models to implement ETANA-DL with cross-collection searching and browsing capabilities. / Master of Science

The integration of chronological and archaeological information to date building construction: an example from Shetland, Scotland, UK.Outram, Zoe, Batt, Catherine M., Rhodes, E.J., Dockrill, Stephen January 2010 (has links)
No / This paper presents new chronological data applied to the problem of providing a date for the
construction of a prehistoric building, with a case study from the Old Scatness Broch, Shetland. The
innovative methodology employed utilises the combination of radiocarbon and optically stimulated
luminescence (OSL) dates with the archaeological information, which includes the stratigraphic relationships
of sampled deposits, context information, and evidence relating to the formation of the deposit.
This paper discusses the scientific validity of the dates produced, and the advantages that the methodology
employed at this site offers for archaeological interpretation. The combined dating evidence
suggests that the broch at Old Scatness is earlier than the conventionally accepted dates for broch
construction. More broadly it shows the value of integration of the specialists at the planning stages of
the excavation. The application of a Bayesian statistical model to the sequences of dates allowed
investigation of the robustness of the dates within the stratigraphic sequences, as well as increasing the
resolution of the resulting chronology. In addition, the value of utilising multiple dating techniques on
the same deposit was demonstrated, as this allowed different dated events to be directly compared as
well as issues relating to the formation of the sampled deposit. This in turn impacted on the chronological
significance of the resulting dating evidence, and therefore the confidence that could be placed in
the results.
