|PARALLEL TRACK 1: EUDAT SERVICES|
CHAIR: JOHANNES REETZ, RZG / MPG, GERMANY
OVERVIEW: Safe Replication (SR) and Data Staging (DS) are EUDAT services for moving data between sites and storage systems for two kinds of purposes. The purpose of SR is to keep the data from a repository safe by replicating it across different geographical and administrative zones according to a set of well-defined policies. It is also a way to store larger volumes of data permanently at those sites which are providing powerful on-demand data analysis facilities. In particular, SR operates on the domain of registered data where data objects are referable via persistent identifiers (PIDs). SR is more than just copying data because the PIDs must be carefully managed when data objects are moved or replicated.
The general purpose of DS is to move data between storage systems, specifically, DS transfers data from the domain of registered data into a temporary storage space, and vice versa, it moves data from any storage space into the domain of registered data, typically a repository.
The session will introduce the problem space of SR and DS, presents the achievements that have been made during the last year for enabling communities to make use of the SR service as well as DS, demonstrates a few use cases, outlines the commonalities and differences between the policies for SR, presents new developments towards a common service layer interface and a data policy management framework.
AGENDA (each presentation is followed by 5 min Q&A):
SESSION TITLE: SIMPLE STORE
OVERVIEW: Many researchers are collaborating across institutional boundaries and are facing the problem of finding an easy way of storing and sharing their data. But even single researchers should want to safeguard their own results and data in a safe storage place that will be kept open and accessible for other researchers in the future. They often have large numbers of small files, for example, files containing derived data in the form of spread sheets or analysis results. Although the information in these small files is important, they usually do not belong to large research collaborations with well-defined data storage plans. These kind of files are known as the “long tail data”, which are often stored locally on laptops and departmental storage devices with the risk of losing valuable scientific data, either because other researchers do not have easy access to the data or because such storage systems are often not adequately secure. To solve this problem EUDAT is working on a service called Simple Store which combines a shared storage space with the possibility to add metadata and to assign persistent identifiers. This session will present the current work and plans on the Simple Store service, related work from other projects and there will be time for discussion on the subject of “long tail data”. Options to provide cloud storage as a temporary low-barrier storage solution will be discussed.

SESSION TITLE: 1.3 METADATA
OVERVIEW: The data subject is hot; it is considered the new oil of the digital area. Data is produced at staggering rates. The main questions are “Where store it?”, “How to find it?” and ”How to make the most of it?”. In this context, metadata is the key to improving and ensuring the quality of data for current and future usage, and metadata catalogues are the place to find the interesting relevant and most valuable data sets. EUDAT is developing a joint metadata catalogue that combines the metadata, gathered from various repositories and sources, and hence bridges key information from research across science domains. This session will present current work and plans on the joint metadata service, the need for harvestable repositories and the challenge to understand and to bridge domain specific ontologies. It will also present related work to the dispersed metadata challenge. The session foresees ample discussion time to hear views and contributions from the participants.
