An e-science infrastructure for collecting, sharing, retrieving, and analyzing heterogeneous scientific data
Johannes-Y. Lohrer · 2018
The process of collecting, sharing, retrieving, and analyzing data is common in many areas of scientific work. While each field has its own workflows and best practices, the general process can be aided by an e-Science infrastructure. The contribution of this thesis is to support the workflow of the scientists which can be split in four parts: In the first part, we introduce xBook, a framework which aids the creation of database application to collect, back-up, and share data. In the second part, we describe the synchronization which is a vital part of the xBook framework that, with the use of timestamps, allows data to be entered offline. The data then can be shared with coworkers for analyses or further processing. It also can be used as a backup system to avoid data loss. Third, we present an architecture allowing data from distributed data sources to be retrieved without a central managing instance. This is achieved with the use of minimal search parameters which are guaranteed to exist in all connected data sources. This architecture is based on the concept of mediators, but gives data owners full control over their data sources as opposed to the traditional mediator where the connected data sources are managed by a central administrator. Fourth we describe an embeddable analysis tool which can be integrated into a base application where the data is gathered. With the aid of simple modules, called ``Workers'', this tool empowers domain experts to easily create analyses particularly designed for their area of work in a familiar working environment. Additionally, we present another tool which allows the graphical display of temporal and spatial information of archaeological excavations. This tool uses an interactive Harris Matrix to order findings temporally and allows the comparison with their spatial location.
