User story
As a longitudinal study, I want to be able to deduplicate the metrics/impact for our data, so that I can see the impact of our study’s data as a whole.
Query strategy
We start with a single dataset that has multiple parts, and then find all parts. We fetch the views, downloads and citations for the whole dataset, and for each part.
Why GraphQL
Aggregation for metrics/impact is a typical use case for GraphQL, as it allows the combination of three steps into one API call:
- start with the PID for the resource you want to aggregate by, e.g. person, organization, funder but also dataset with multiple parts, e.g. one subset per year
- collect all research outputs associated with this PID
- collect metrics (e.g. citations, views and downloads) for each research output
Use the following query in the GraphQL client at https://api.datacite.org/graphql
{
dataset(id: "https://doi.org/10.14291/tccon.ggg2014") {
id
titles {
title
}
citationCount
viewCount
downloadCount
partCount
parts {
nodes {
id
titles {
title
}
citationCount
viewCount
downloadCount
}
}
}
}
