There are four different types of research products in the OpenAIRE Graph:
- Research data
- Research software
- Other research products.
We deduplicate (merge) different records of research products and keep the metadata of all instances.
Research products intended for human reading (published articles, pre-prints, conference papers, presentations, technical reports, etc.)
The sources from which the description of the research data has been collected reflect and support their own granularity, we do not define it.
Source code or software package developed and/or used in a research context
Other research product
Anything that does not fall into the previous categories (e.g. workflow, methods, protocols)
Projects refer to project identifiers/grant IDs used by funders.
For some funders, we have agreed to include research outputs that cannot be linked to a specific project. In some cases, authors might acknowledge funding by a funder but do not provide additional information regarding the project number. Currently, such mined links are associated in the research graph with a project entity we name "unidentified" project. Some indicators are affected by this, such as the 'number of projects granted' that will appear increased by one (+1) compared to the actual number of project identifiers provided by the funder. However, this solution helps provide more accurate numbers for the research output of funders for which this applies, and for which otherwise these funded outputs would have been missed. In the extreme case, a couple of funders have not provided any grantIDs, as authors rarely acknowledge them (e.g., the Canadian funders in OpenAIRE). In those cases, Project indicators have been disabled as only one project will show.
