DataSpaceR's 1.0.0 rebuilt its query API and opened up HIV antibody sequence data.

hiv-researchimmunology-dataapi-clientantibody-sequencesr-packages
◆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.

◆Recent moves

    LANL metadata requests restored and BCR queries batched

    A follow-up to the 1.0.0 rewrite: LANL monoclonal-antibody metadata requests are restored, BCR sequence study queries are batched, and object tagging moved from class to attr. Restoring the LANL functions suggests the major release removed more than intended.

    Query API rebuilt and DAASH antibody sequence access added

    ⚡ SPARK

    The major release that reshapes the client: grid filtering and view methods replaced by data.table filtering on an availableMabs object, that pattern applied to every query method, multi-entry queries throughout, and a new class for DAASH antibody sequence data.

    LANL metadata added to neutralising-antibody pulls

    Adds LANL metadata to neutralising-antibody data pulls and exposes virus name mapping tables as an active binding. This is the LANL integration that 1.0.0 dropped and 1.0.1 restored.

    Session fix for CDS reports and snake-case bindings

    Fixes a missing cookie session name that blocked the package inside CDS reports, surfaces non-integrated datasets in the available-datasets binding, and moves active binding names to snake case. Early groundwork on the naming consistency the 1.0.0 rewrite completes.
