cffr vs DataSpaceR: at a glance
What is cffr?
cffr keeps CITATION.cff generation in step with the standard and its R sources.
The package generates and validates CITATION.cff files from R package metadata. Recent work is validation and parsing accuracy rather than new outputs: cff_validate() moved onto the ajv engine through jsonvalidate for clearer errors, ROR identifiers act as a website fallback for people and entities, and DOIs are now detected in inst/CITATION url fields including dx.doi.org forms.
What is DataSpaceR?
DataSpaceR's 1.0.0 rebuilt its query API and opened up HIV antibody sequence data.
The R client for the CAVD DataSpace reached 1.0.0 in July 2026 after five years of small fixes. The release removed the mAb grid filtering and view methods in favour of filtering an availableMabs object with data.table syntax, applied that pattern to every query method, and added a class for querying DAASH, the Database of Annotated Antibody Sequences for HIV-1. The August patch restored the LANL monoclonal-antibody metadata requests and batched BCR sequence queries.

cffr keeps CITATION.cff generation in step with the standard and its R sources.
◆ Current state
The package generates and validates CITATION.cff files from R package metadata. Recent work is validation and parsing accuracy rather than new outputs: cff_validate() moved onto the ajv engine through jsonvalidate for clearer errors, ROR identifiers act as a website fallback for people and entities, and DOIs are now detected in inst/CITATION url fields including dx.doi.org forms.
◆ Where it's heading
The package tracks two moving targets — the Citation File Format schema and R's own person and citation handling, which has broken extraction twice in recent releases. Between those, releases pick up ecosystem details: Codeberg recognised as a repository host, CRAN-to-SPDX licence mappings refreshed, GitHub Action defaults changed to save quota. The most recent release is an internal refactor carried out with AI assistance, with no user-facing change.
◆ Prediction
With validation migrated and the R 4.5 person changes absorbed, the next release most likely follows a Citation File Format schema update rather than adding capability.
DataSpaceR
2.5ANALYTICS
DataSpaceR's 1.0.0 rebuilt its query API and opened up HIV antibody sequence data.
◆ Current state
The R client for the CAVD DataSpace reached 1.0.0 in July 2026 after five years of small fixes. The release removed the mAb grid filtering and view methods in favour of filtering an availableMabs object with data.table syntax, applied that pattern to every query method, and added a class for querying DAASH, the Database of Annotated Antibody Sequences for HIV-1. The August patch restored the LANL monoclonal-antibody metadata requests and batched BCR sequence queries.
◆ Where it's heading
The package is converging on one query idiom — build a filtered object, then fetch — instead of per-domain grid methods, and each class now accepts multiple studies or antibodies rather than one. The 1.0.1 patch suggests the rewrite dropped functionality that users noticed, and it was put back rather than redesigned.
◆ Prediction
With DAASH access in place and the query surface unified, the next work is most likely more sequence-domain coverage and follow-up fixes to the batched query paths introduced in 1.0.1.
