View source: R/oarg_decode.R

OpenAIRE Research Graph files are json-files that contain a record identifier and a BASE64 encoded text string representing the metadata. This function decodes these strings and saves them locally.

1	oarg_decode(oaire = NULL, limit = NULL, records_path = NULL, verbose = TRUE)

`oaire`	compressed json file
`limit`	number of records to be decoded
`records_path`	directory for the xml files
`verbose`	print some information on what is going on

De-coding and storing the records individually from an OpenAIRE Research Graph dump allows to process the records independent from each other, which is a common approach when working with big data.

Because the dumps are quite large, the function furthermore has a parameter that allows setting a limit, which is helpful for inspecting the output first.

By default, a progress bar presents the current state of the process.

Exports de-compressed XML-formatted record, storing them locally as zip files. The file name represents the record identifier.

## Not run: 
library(jsonlite)
dump_file <- system.file("extdata", "", package = "openairegraph")
# a dump file is in json format
loaded_dump <- jsonlite::stream_in(file("dump_file"))
# writes out each XML-formatted record as a zip file to a specified folder
oaire_decode(loaded_dump, limit = 10, records_path = "data/")
