This diploma thesis topic is focused on additional module/tool development requested by the biobanking community in Germany. It is intended to enrich sample and clinical information stored at biobanks with metadata obtained from sample usage. The work covers an analysis and understanding of the existing infrastructure (Bridgehead and Locator) for samples and data search, design of new functionality, and a first prototype of the module/tool realizing the new functionality. Since the components are handling patient and sample data, the thesis includes a consideration of the security aspects of such an infrastructure, as well as safe communication protocols. The new functionality should enable the provision of information (metadata) about the results gathered from the samples by researcher to the biobank which provided the data and samples at the beginning of a scientific project. The metadata will be propagated back to the Bridgehead and will be searchable via the Locator component. In this way, the research results based on the samples and data from the biobank will be linked to the sample and data source, making them findable and accessible to the wider scientific community. The number of repeating sample analyses should thus diminish, because the researchers will be able to find out that a given sample analysis has already been done and will easily be able to find the results. The student will work with CQL, FHIR servers, Java, and be part of a team of developers working on the components mentioned above and maintaining the infrastructure used by German biobanks.
