Data Model: Information Space Entities and Relationships. In our reasoning we generalize the concept of datasets and publications to that of project result, so as to be able of including further kinds of research outputs. OpenAIRE initially proposes two kinds of results: datasets (e.g., experimental data, software products) and publications. But others can be added in the future (e.g., patents). Besides, project results are always associated to one or more instances of the results, in the sense that different “physical representations” of the same result may exist. For example, the same publication may be kept in two different repositories, both exposing the payload file (e.g., PDF) at different internet locations (URLs). Morover, an instance of a result is represented as a combination of one or more web resources relative to the sub-parts of the result and of the internet data sources from which such resources are made available.1 Similarly, we extend the notion of authors of publications or datasets to that of persons, to include in the same set people connected to project fundings or organizations. For example “authorship” relationships between results and persons, which represent the fact that a given person has (co-)authored a given result while being affiliated with a given organization. Organizations include companies, research centers or institutions involved as project partners or as responsible of operating data sources. Information about organizations will be initially collected from CORDA and XXXX systems, as being related to projects, or be ingested by users, for example to complete authorships information in the database. Of crucial interest to OpenAIREplus is also the identification of the funding programmes which co-funded the projects that have led to a given result: 1 The purpose of the project result-instance-web resource model is to capture a list of internet pointers relevant to the project result and not that of capturing the compound object structure which some results may have. If a project result is a compound object (e.g. ORE aggregation), its instances will likely be associated to web resources embodying its compound object nature (e.g., ORE resource maps). • EC FP7 programme projects data will be fetched from the authoritative XX XXXXX database, together with the organizations or persons which are participants of such projects. • Data relative to National funding schemes and relative projects will be instead fetched from XXXX systems, together with other entities which may be typically...
