<div> <p>The AlpEnDAC (Alpine Environmental Data Analysis Center) platform (www.alpendac.eu) aims to collect scientific data measured on different high-altitude research stations in the alpine region and beyond. It provides research data management, analysis and simulation services and supports the research activities of the VAO (Virtual Alpine Observatory) community.</p> <p>With funding from the Bavarian State Ministry of the Environment and Consumer Protection, a new development cycle of the platform was launched in 2019. Novel components for Computing on Demand (CoD), Service on Demand (SoD) and Operating on Demand (OoD) will be integrated into the system. These will help to implement a near-real-time (NRT) decision support for the scientist during measurement processes and a better control of the measurement process.</p> <p>In this work, the authors present a stream processing architecture to couple the new CoD, SoD and OoD components. Data from measurements (or also simulations) are normally ingested via a representational state transfer application programming interface (REST API) into the AlpEnDAC system. Before such data are stored in the data base, they will be run through a central stream processing engine, based on a message queue (e.g. Apache Kafka) and a series of specialized workers to process the data. A rule engine and analytics tools are connected to this engine and allow the automatic triggering of, e.g., measurements, HPC simulations, or evaluation and notification services in NRT. The services will be usable and configurable, as much as possible, via the AlpEnDAC web portal where also certain measurement device settings can be adjusted. With these developments, we want to make environmental scientists profit from NRT data collection and processing, as it is already an everyday tool, e.g., in the Internet-of-Things sector and in commercial applications.</p> </div>

AbstractThis paper details an approach to re-purposing scientific data as presented on a web page for the sole purpose of making the data more available for searching and integration into other websites. Data ‘scraping’ is used to extract metadata from a set of pages on the National Institute of Standards and Technology (NIST) website, clean, organize and store the metadata in a MySQL database. The metadata is then used to create a new website at the authors institution using the CakePHP framework to create a representational state transfer (REST) style application program interface (API). The processes used for website analysis, schema development, database construction, metadata scraping, REST API development, and remote data integration are discussed. Lessons learned and tips and tricks on how to get the most out of the process are also included.

The environmental sciences are witnessing a data revolution as large amounts of data are being made available at an increasing rate. Many datasets are being published through operational monitoring programs, research activities and global earth observation virtual laboratories. An important aspect is the ability to query relevant metadata which can potentially provide useful information to discover, access and interpret environmental datasets, information about the data providers themselves, data services, data encodings, observation and measurement properties and data service endpoints. However, support for producing and accessing metadata descriptions in a flexible, extensible, easily integrated and easily discovered manner is lacking as current methods require interpreting multiple standards and formalisms. In this paper, we propose components to streamline discovery and access of hydrological and environmental data: a Data Provider Node ontology (DPN-O) which allows precise descriptions to be captured about datasets, data services and their interfaces; and a Data Brokering Layer which provides an Application Programming Interface (API) for registering metadata for discovery and query of registered DPN datasets. We discuss this work in the context of the eReefs project which is developing an integrated information platform for discovery and visualization of observational and modelled data of the Great Barrier Reef.

<p>The “Alpine Environmental Data Analysis Centre” (AlpEnDAC) is a research data management and analysis platform for research facilities around the Alps and similar mountain ranges. It provides the computational infrastructure for the Virtual Alpine Observatory (VAO), which is a research network of European high-altitude research stations (http://www.vao.bayern.de).</p><p> </p><p>Within the scope of previous work, the platform was developed with the focus on research data and metadata management as well as analysis and simulation tools. It offers the possibility to store and retrieve data securely (data-on-demand), to share it with other scientists and to interpret it with the help of computing-on-demand solutions via a user friendly web-based graphical user interface. The AlpEnDAC allows the analysis and consolidation of heterogeneous data sets from ground-based to satellite instruments.</p><p> </p><p>In a further development phase, launched on 1 August 2019, the existing services of the AlpEnDAC will be supplemented by new components in the fields of user support and quality assurance. Furthermore, the modelling and analysis software portfolio will be extended, focusing on the development of innovative services in the fields of service-on-demand and operating-on-demand as well as the integration of new data sources and measurement instruments.</p><p> </p><p>The AlpEnDAC helps environmental scientists to benefit from modern data management, data analysis, and simulation techniques. The VAO network, now including ten countries (Austria, France, Germany, Georgia, Italy, Norway, Slovenia, Switzerland, Bulgaria, and the Czech Republic) is an ideal and exciting context for developing the AlpEnDAC with researchers.</p><p> </p><p>This project receives funding from the Bavarian State Ministry of the Environment and Consumer Protection.</p>

<p>Scientific data analysis experiments and applications require software capable of handling domain-specific and data-intensive workflows. The increasing volume of scientific data is further exacerbating these data management and analytics challenges, pushing the community towards the definition of novel programming environments for dealing efficiently with complex experiments, while abstracting from the underlying computing infrastructure. </p><p>ECASLab provides a user-friendly data analytics environment to support scientists in their daily research activities, in particular in the climate change domain, by integrating analysis tools with scientific datasets (e.g., from the ESGF data archive) and computing resources (i.e., Cloud and HPC-based). It combines the features of the ENES Climate Analytics Service (ECAS) and the JupyterHub service, with a wide set of scientific libraries from the Python landscape for data manipulation, analysis and visualization. ECASLab is being set up in the frame of the European Open Science Cloud (EOSC) platform - in the EU H2020 EOSC-Hub project - by CMCC (https://ecaslab.cmcc.it/) and DKRZ (https://ecaslab.dkrz.de/), which host two major instances of the environment. </p><p>ECAS, which lies at the heart of ECASLab, enables scientists to perform data analysis experiments on large volumes of multi-dimensional data by providing a workflow-oriented, PID-supported, server-side and distributed computing approach. ECAS consists of multiple components, centered around the Ophidia High Performance Data Analytics framework, which has been integrated with data access and sharing services (e.g., EUDAT B2DROP/B2SHARE, Onedata), along with the EGI federated cloud infrastructure. The integration with JupyterHub provides a convenient interface for scientists to access the ECAS features for the development and execution of experiments, as well as for sharing results (and the experiment/workflow definition itself). ECAS parallel data analytics capabilities can be easily exploited in Jupyter Notebooks (by means of PyOphidia, the Ophidia Python bindings) together with well-known Python modules for processing and for plotting the results on charts and maps (e.g., Dask, Xarray, NumPy, Matplotlib, etc.). ECAS is also one of the compute services made available to climate scientists by the EU H2020 IS-ENES3 project. </p><p>Hence, this integrated environment represents a complete software stack for the design and run of interactive experiments as well as complex and data-intensive workflows. One class of such large-scale workflows, efficiently implemented through the environment resources, refers to multi-model data analysis in the context of both CMIP5 and CMIP6 (i.e., precipitation trend analysis orchestrated in parallel over multiple CMIP-based datasets).</p>

The use of information technology these days are very high. From business through education activities tend to use this technology most of the time. Information technology uses computer networks for integration and management data. To avoid business problems, the number of network devices installed requires a manageable network configuration for easier maintenance. Traditionally, each of network devices has to be manually configured by network administrators. This process takes time and inefficient. Network automation methods exist to overcome the repetitive process. Design model uses a web-based application for maintenance and automates networking tasks. In this research, the network automation system implemented and built a controller application that used REST API (Representational State Transfer Application Programming Interface) architecture and built by Django framework with Python programming language. The design modeled namely As-RaD System. The network devices used in this research are Cisco CSR1000V because it supports REST API communication to manage its network configuration and could be placed on the server either. The As-RaD System provides 75% faster performance than Paramiko and 92% than NAPALM.
