OpenAIRE

OpenAIRE is an open science initiative, which supports the Open Access policy of the European Commission. This R package OpenAIRE provides access from within R to the OpenAIRE RESTful APIs, which are intended for metadata discovery and exploration only.

Installation

You can install the development version of OpenAIRE like so:

# install.packages("devtools")
devtools::install_github("KTH-Library/OpenAIRE")

Example

This is a basic example which shows you how to retrieve data from the OpenAIRE search APIs:

library(OpenAIRE)

Filtering results

Parameters can be specified to filter search results:

# use parameters to filter projects
openaire("projects", params = api_params(
  format = "tsv", 
  proj_country = "SE",
  proj_org = "Royal Institute of Technology",
))

Paging

A function provides crawling results, page by page:

openaire_crawl("projects", page_size = 100, params = api_params(
  format = "xml", 
  proj_country = "SE",
  proj_org = "Royal Institute of Technology")
)
#> Fetching approximately 835 hits in 9 batches of 100 records
