datasetjson vs sofa: at a glance
What is datasetjson?
datasetjson rebuilt its object model to track the CDISC Dataset-JSON 1.1 schema.
datasetjson reads and writes CDISC Dataset-JSON, the JSON replacement for SAS transport files in clinical-trial submissions. The package went from a thin reader in 2023 to a redesigned interface in 0.3.0 that targets the 1.1.0 schema, uses yyjsonr as its JSON backend, and exposes column metadata as first-class arguments. Development is contributor-driven inside the Atorus and pharmaverse orbit.
What is sofa?
A CouchDB client for R whose recent work is all test infrastructure, not new routes.
sofa wraps the CouchDB HTTP API for R — database and document CRUD, Mango queries and indexes, design documents, replication, and attachments, organized around a Cushion connection object. Feature development effectively stopped after 0.4.0 brought CouchDB v3 compatibility in 2020. The two 2026 releases are a testing and packaging overhaul: 0.4.1 rebuilt the suite around a crul-mocked fake CouchDB so tests no longer need Cloudant or a local Docker instance, reaching 100% coverage, and 0.4.2 cleared CRAN check notes.

datasetjson rebuilt its object model to track the CDISC Dataset-JSON 1.1 schema.
◆ Current state
datasetjson reads and writes CDISC Dataset-JSON, the JSON replacement for SAS transport files in clinical-trial submissions. The package went from a thin reader in 2023 to a redesigned interface in 0.3.0 that targets the 1.1.0 schema, uses yyjsonr as its JSON backend, and exposes column metadata as first-class arguments. Development is contributor-driven inside the Atorus and pharmaverse orbit.
◆ Where it's heading
The package's roadmap is not its own — it tracks a CDISC standard that is still moving, and 0.3.0 is what happens when the standard revises: object model, read and write paths, and JSON backend all changed together. Performance was addressed in the same pass, which matters because submission datasets are large enough that a slow serialiser is a real constraint.
◆ Prediction
The next significant release will most likely follow the next Dataset-JSON schema revision rather than an internal roadmap, given that 0.3.0 was driven entirely by the 1.1.0 update.
sofa
2.5ANALYTICS
A CouchDB client for R whose recent work is all test infrastructure, not new routes.
◆ Current state
sofa wraps the CouchDB HTTP API for R — database and document CRUD, Mango queries and indexes, design documents, replication, and attachments, organized around a Cushion connection object. Feature development effectively stopped after 0.4.0 brought CouchDB v3 compatibility in 2020. The two 2026 releases are a testing and packaging overhaul: 0.4.1 rebuilt the suite around a crul-mocked fake CouchDB so tests no longer need Cloudant or a local Docker instance, reaching 100% coverage, and 0.4.2 cleared CRAN check notes.
◆ Where it's heading
This is a rOpenSci package being brought back to a maintainable state rather than extended. The 0.4.1 decision to mock the server is the consequential one — it decouples CI from a live CouchDB, which is what made the cross-platform GitHub Actions workflow and full coverage possible at all. Two genuine bugs surfaced in that process, in db_replicate() URL construction against non-Cloudant servers and db_alldocs(disk=) not returning the documented file path, suggesting the untested paths had drifted.
◆ Prediction
With the test harness now self-contained, the next plausible move is catching up on CouchDB routes added since v3 rather than further infrastructure work, though nothing in these entries commits to it.
