📄️ The Relationship object
A relationship in the Graph is represented with the data type presented in this page, which aims to model a directed edge between two nodes, providing information about its semantics, provenance and validation.
📄️ Relationship types
The following table lists all the possible relation semantics found in the Graph Dataset.
📄️ Author Affiliation Relation
An author affiliation relation connects a person to an organization they have been affiliated with. The relation is derived from employment records in ORCID and carries the list of periods during which the affiliation was active, where this information is available. For details on how this relation is produced in the Graph workflow, see Step 1 in the Person and relations methodology.
📄️ Authorship Relation
An authorship relation connects a person to a research product they have authored. It carries information about the author's role in the work, their position in the author list, whether they are the corresponding author, and the affiliations they declared at the time of publication. For details on how this relation is generated in the Graph workflow, see Step 3 in the Person and relations methodology.
📄️ CoAuthorship Relation
A co-authorship relation connects two persons who have collaborated as co-authors on one or more research products. The relation is symmetric and carries a counter recording how many products the two persons have published together. For details on how this relation is derived, see Step 3 in the Person and relations methodology.
📄️ Project Participation
A project participation relation connects a person to a funded project they have participated in. It captures the role held by the person within the project and, where available, the organizational affiliation under which they participated. For details on how this relation is produced (direct records and inferred participation through project deliverables), see Step 1 and Step 2 in the Person and relations methodology.
