Scenario Host. The Portuguese regulations [5] state that the National Laboratory for Civil Engineering is responsible for keeping an electronic archive of data concerning the dam safety. Thus, the preservation of this data is a legal obligation. Moreover, that obligation defines the duties of the different parties involved in dam safety, namely the dam owners, the dam safety authority and the dam engineers and builders. As a consequence, several entities are compelled to share data, and thus must face interoperability and preservation issues when dealing with heterogeneous sources of information [6]. Currently, LNEC uses a modular information system (GestBarragens) that provides components to manage dam observations, visual inspections, physical models and mathematical models. It also supports the management of technical documents and provides a set of exploitation tools, in the form of tabular and chart reports, graphical visualization of geo-referenced information, among others. However, the GestBarragens system was not designed for preservation purposes. Indeed, it supports the operational procedures to manage information concerning the dam safety, but does not assure the preservation of this information. It is a web-based system developed on the top of the .NET framework, where the underlying data is stored and managed in an Oracle 10g database. It uses a SOAP interface to provide and expose exploitation services as well as multiple ingest services. Figure 3 depicts the user interface of the GestBarragens system.
Scenario Host. The myExperiment2 project is a virtual research environment to support scientists using scientific workflows. It was developed under the scope of the myGrid3 research group, a multi-institutional and multi-disciplinary group involving different institutions such as the University of Manchester, the University of Southampton, the University of Oxford, among others. Figure 5 depicts a screenshot of the myExperiment interface.
Scenario Host. The Portuguese Laboratory of Instrumentation and Experimental Particles (LIP) is a research laboratory in the fields of Experimental High Energy Physics, Astroparticles, Medical Physics, radiation detection instrumentation, data acquisition and data processing. Its research activities are developed in the framework of large collaborations at CERN and at other international organizations. A typical scenario that can be observed in LIP is that of a PhD student or senior researcher performing small or medium collider or astroparticles experiments and analyzing data resulting from these experiments. Such an experiment will typically involve small data collections and might make use of several tools: (i) Experiment specific data processing software, which might be totally or partially developed by the researcher; (ii) Data analysis tools, which are used for analyzing the data produced in the context of the experiment; (iii) Simulation software for simulating the same experiments for comparing results; and (iv) other varied scripts. The data that is used in such experiments is heterogeneous and might originate from diverse sources, and might include raw or reconstructed data, databases, and data resulting from simulations. Data resulting from such experiments might as well use several formats, some of them exclusive for the experiment. Such experiments result in several publications describing the results obtained. 4 xxxx://xxxx.xxxx.xx/drupal/
