This Deliverable defines and describes the overall Data Management Plan (DMP) of the iHelp project. The DMP seeks to identify the best practices and specific standards for the generated data and assess their suitability for sharing and reuse in accordance with official guidelines. To this end, it aims to support the data management lifecycle for all data that will be collected, processed or generated by the project in order to maximise their accessibility and usage, according to the H2020 Pilot on Open Research Data (ORDP) in which the project participates. The iHelp DMP will comply with the European Commission’s (EC) Data Management Plan template and will specify how the generated data will be easily discovered and accessed, ensuring open access by adopting the adequate licensing scheme (e.g. Creative Commons License). The latter reflects the status of the data that are collected, processed, or generated, and the respective methodology and standards, whether and how these data will be shared and made open, and how they will be curated and preserved. The DMP defines the general policy and approach to data management in the iHelp project, covering the data management related issues both on the administrative and on the technical level. To this end, this deliverable includes topics like application reconfiguration logs and monitoring metrics collection, publication and deposition of open data, the data repository infrastructure and compliance with the Open Access Infrastructure for Research in Europe (OpenAIRE). The current document also defines the foreseen resources needed for the data openness, and the ethical aspects that are taken into consideration in the context of iHelp.
