Content acquisition policy

  • Aggregation policies by type of product

    Literature, Datasets, Software, other research products
    OpenAIRE accepts the metadata records of all scientific products whose structure respect the model and semantics as expressed by the OpenAIRE guidelines. This means that both Open Access and non-Open Access material will be included and links to other products will be resolved where this is possible (i.e. the provided PIDs have a resolver).

    Accession numbers
    Datasets with accession numbers (database entries) are not included as OpenAIRE datasets but, when a relationship to product exists, are included as properties of the related products. More specifically, they are included as values of the property externalReference of product metadata; externalReference includes a URL to the splash page, the target web site name, the ID and an ID type (e.g. PDB).

    Full-text of scientific literature
    OpenAIRE collects Open Access literature product files whenever these are accessible from the URL provided in the metadata record. The literature full-text is used for text-mining purposes. End-users willing to access, download, and read the actual files will not be able to do so from OpenAIRE, but will be forwarded to the original source of deposition. For further information on the use of full-texts, please view OpenAIRE’s ToU.

  • Rationale

    The OpenAIRE service infrastructure harvests metadata about scholarly communication
    products (literature, datasets, software, and other research products) and links between such products from a range of institutional or subject repositories, national and institutional research information portals, aggregators, e-journals, data repositories, and software repositories. In addition, it infers links between literature and such products via advanced text and data mining techniques (TDM). The resulting information graph (i.e. interlinked sets of objects) is intended to favour monitoring of open science and open science publishing workflows (e.g. science reproducibility and transparent assessment).

    • Coverage OpenAIRE will actively pursue harvesting content from European but also non-European repositories;
      Reproducibility The OpenAIRE graph aims at linking scientific literature, namely the narration of scientific motivation and process, with all products used or resulting in the relative research activity
    • Monitoring The OpenAIRE graph links research products with the funders and projects resulting from their grants
    • Research communities The OpenAIRE graph links research products with the communities for which they are relevant, in order to provide a (multi-)community-view of the scholarly output
    • Quality Data sources and repositories are quality-controlled: their metadata respects the OpenAIRE guidelines and their import in OpenAIRE is curated by OpenAIRE data curators. Click here to see the repositories that OpenAIRE currently harvests from.
    • Terms of Use for content providers Data source managers read and accept OpenAIRE ToU (and vice versa) in order for OpenAIRE to re-use their content under specific consent, warranties, and license.product 
  • Research products and their associated types in OpenAIRE

    The details mappings between input records and the target OpenAIRE entities are specified below. Independently from the category of input repository, the aggregation process identifies for each input record a term in a common vocabulary. Each term of this vocabulary is then associated to one of the four OpenAIRE entities literature, dataset, software, and ORP as described in the following tables.


    Remark: Such associations may be modified over time to reflect the general preferences and requirements of the OpenAIRE user community.

  • Aggregation policy by category of repository

    OpenAIRE services collect metadata about four typologies of products: literature, datasets, software, and “other research products” (ORPs). Metadata can be collected from four main categories of repositories: literature repositories (including institutional/thematic repositories, publishers, and catalogues), data repositories, software repositories, and ORP repositories. As things stands there is no one-to-one relationships between a type of repository and the products it contains, e.g. literature repositories may indeed also contain datasets, software, and ORPs. Accordingly, the aggregation process needs to classify the products collected from a repository in order to assign them to the correct entity class in OpenAIRE. The distribution rules are illustrated in Table 1, which follow vocabularies in the OpenAIRE guidelines and Version 4.0 of DataCite. Please note that such mappings may be modified over time to reflect the general preferences and requirements of the OpenAIRE user community.
