A dataspace is an emerging information management approach used to tackle heterogeneous data sources that supports requirements, such as standardization, enrichment, and linking of data in an incremental manner. Designing and implementing a dataspace is the core of the Waternomics information platform and is one of the major objectives for the Waternomics project. In the Waternomics vision collecting, standardizing, enriching and linking water usage data coming from sensors together with other relevant contextual data sources is a key step needed for effective analytics to drive decision making: e.g., planning, adjustments and predictions and to raise user awareness of water consumption. In this report, we detail the current design and implementation of the dataspace using Linked Data as a recommended W3C best practice for exposing, sharing and connecting pieces of data, information and knowledge. The deliverable introduces the concept of Linked Data, Semantic Web and Web of Data and how these are applied in the context of the Waternomics dataspace. The primary contribution of this report is a customized architecture for implementing a Linked Water Dataspace. The deliverable exposes a first version of a water data ontology used for semantically describing sensors and their data. The design of the ontology is informed of by the requirements of the pilots for importing or exporting data from/to the dataspace. © Waternomics consortium Page 5 of 84 619660 Table of Contents Executive Summary ................................................................................................................. 5 Table of Contents ..................................................................................................................... 6 List of Figures .......................................................................................................................... 8 List of Tables .......................................................................................................................... 10 List of Listings ........................................................................................................................ 11 1 Introduction .................................................................................................................... 12 1.1 Work Package 3 Objectives ............................................................................ 12 1.2 Purpose and Target Group of the Deliverable ................................................. 12 1.3 Relations to other Activities in the Project ....................................................... 13 1.4 Document Outline ............................................................................................ 14 1.5 About Waternomics ......................................................................................... 14 2 Functional Dataspace Requirements ............................................................................ 16 3 Linked Data ..................................................................................................................... 18 3.1 Overview ......................................................................................................... 18 3.2 The Semantic Web .......................................................................................... 19 3.3 Web of Data .................................................................................................... 21 3.4 Linked Water Data ........................................................................................... 23 3.5 Conclusion ...................................................................................................... 24 4 State of the Art Analysis ................................................................................................ 25 4.1 Data Adapters ................................................................................................. 25 4.2 Linked Data Platforms ..................................................................................... 28 4.2.1 Virtuoso .......................................................................................... 28 4.2.2 LinDA ............................................................................................. 29 4.2.3 Pubby ............................................................................................. 29 4.2.4 Apache Marmotta ........................................................................... 30 4.2.5 LDP4j ............................................................................................. 30 4.2.6 OpenCube Toolkit .......................................................................... 31 4.2.7 LOD2 Linked Data Stack ............................................................... 32 4.2.8 CKAN ............................................................................................. 33 4.3 Entity Management ......................................................................................... 33 4.3.1 Master Data Management ............................................................. 34 4.3.2 Crowdsourced Entity Management ................................................ 35 4.3.3 Collaborative Entity Management .................................................. 36 4.4 Lambda Architecture ....................................................................................... 37 4.4.1 DRUID Platform ............................................................................. 37 4.4.2 Apache Spark ................................................................................ 38 4.5 Conclusion ...................................................................................................... 39 5 A Realtime Linked Water Dataspace ............................................................................. 41 5.1 Dataspace Overview ....................................................................................... 43 5.2 The Dataspace

Special thanks goes out to Dr. Sebastiano Panichella for his instructions, guidance and help during the making of this thesis, without whom this would not have been possible. I would also like to express my gratitude to Dr. Fabio Polomba, Dr. Yann-Gaël Guéhéneuc and Dr. Nikolaos Tsantalis for providing me access to their research and always being available for questions. Last, but not least, do I want to thank my parents, sisters and nephews for the support and love they’ve given all those years. Abstract With the importance of software in today’s society, malfunctioning software can not only lead to disrupting our day-to-day lives, but also large monetary damages. A lot of time and effort goes into the development of test suites to ensure the quality and accuracy of software. But how do we elevate the quality of test code? This thesis presents TestSmellDescriber, a tool with the ability to generate descriptions detailing potential problems in test cases, which are collected by conducting a Test Smell analysis.

  • Linked Data Notifications and Activitypub Client and Server Student: Bc
    ASSIGNMENT OF MASTER’S THESIS Title: Linked Data Notifications and ActivityPub Client and Server Student: Bc. Antonín Karola Supervisor: RNDr. Jakub Klímek, Ph.D. Study Programme: Informatics Study Branch: Web and Software Engineering Department: Department of Software Engineering Validity: Until the end of summer semester 2019/20 Instructions The student will get familiar with Linked Data, the RDF data model, the recent W3C Recommendations [1][2][3] and the Solid project [4], a recent activity of the inventor of the Web, Sir Tim Berners-Lee. The student will implement a client and a server supporting decentralized messaging on the Web according to the Linked Data Notifications [2] and ActivityPub [3] W3C Recommendations in support of the Web re- decentralization. The client part will be a new, user friendly messaging application. Based on the analysis of existing Solid server implementations, the student will determine what is missing in the existing implementations for the given task. The missing features will be implemented either as a new Solid server, or an existing implementation will be enhanced. The client and the server will be documented, evaluated, tested and published as open-source on GitHub. The tests will consist of unit tests and tests of compatibility with existing tools implementing the Recommendations.

  • A Geosparql Compliance Benchmark Which Aims to Measure the Extent to Which an RDF Triplestore Complies with the Requirements Specified in the Geosparql Standard
    AGEOSPARQL COMPLIANCE BENCHMARK APREPRINT Milos Jovanovik Timo Homburg Ss. Cyril and Methodius Univesity in Skopje, N. Macedonia Mainz University Of Applied Sciences, Germany OpenLink Software, London, UK [email protected] [email protected] Mirko Spasic´ University of Belgrade, Serbia OpenLink Software, London, UK [email protected] February 12, 2021 ABSTRACT We propose a series of tests that check for the compliance of RDF triplestores with the GeoSPARQL standard. The purpose of the benchmark is to test how many of the requirements outlined in the standard a tested system supports and to push triplestores forward in achieving a full GeoSPARQL compliance. This topic is of concern because the support of GeoSPARQL varies greatly between different triplestore implementations, and such support is of great importance for the domain of geospatial RDF data. Additionally, we present a comprehensive comparison of triplestores, providing an insight into their current GeoSPARQL support. Keywords GeoSPARQL · Benchmarking · RDF · SPARQL 1 Introduction The geospatial Semantic Web [1] as part of the Semantic Web [2] represents an ever-growing semantically interpreted wealth of geospatial information. The initial research [3] and the subsequent introduction of the OGC GeoSPARQL standard [4] formalized geospatial vector data representations (WKT [5] and GML [6]) in ontologies, and extended the SPARQL query language [7] with support for spatial relation operators. arXiv:2102.06139v1 [cs.DB] 11 Feb 2021 Several RDF storage solutions have since adopted GeoSPARQL to various extents as features of their triplestore implementations [8, 9]. These varying levels of implementation may lead to some false assumptions of users when choosing an appropriate triplestore implementation for their project.
