How to Write FHIR Data to NDJSON Files using R's pathling Package
Write FHIR data to NDJSON files - R R Write
Summary
The `pathling` package in R demonstrates the use of the function `ds_write_ndjson` to write structured data, such as FHIR resources, into a directory of NDJSON files. This provides a technical method for efficiently splitting and saving large datasets.
Details
This article details the functionality of the `ds_write_ndjson` function within the R data processing package `pathling`. The primary purpose of this function is to take data from a specified data source (DataSource object) and write it out into NDJSON (Newline Delimited JSON) format across multiple files. Specifically, the process involves segmenting the output by resource type. Each distinct resource type will be saved as a separate file with the `.ndjson` extension. This capability is crucial for handling large datasets based on standards like FHIR, allowing them to be exported in a machine-readable and easily manageable format. The provided example demonstrates the workflow: first, reading existing NDJSON data using `pathling_read_ndjson`, and then passing this source to `ds_write_ndjson` to write the structured data to a specified path. This technical procedure is fundamental for migrating standardized healthcare datasets (like FHIR) into analysis environments or storage systems.
