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.

What is webchem?

Adding chemical databases with one hand while public ones close programmatic access with the other.

webchem is the R interface to public chemical data — retrieving identifiers, properties and structures across roughly a dozen web services. Its release history reads as a running account of which of those services still allow automated access. Version 1.3.0 removed two functions outright because their sources withdrew: ChemIDplus was retired by the NLM, and PAN stopped supporting programmatic access. Version 1.3.1 continues the pattern, updating URLs that stopped working and noting that ChemSpider InChIKey validation now requires an API key like the rest of that provider's endpoints.

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.

Adding chemical databases with one hand while public ones close programmatic access with the other.

◆ Current state

webchem is the R interface to public chemical data — retrieving identifiers, properties and structures across roughly a dozen web services. Its release history reads as a running account of which of those services still allow automated access. Version 1.3.0 removed two functions outright because their sources withdrew: ChemIDplus was retired by the NLM, and PAN stopped supporting programmatic access. Version 1.3.1 continues the pattern, updating URLs that stopped working and noting that ChemSpider InChIKey validation now requires an API key like the rest of that provider's endpoints.

◆ Where it's heading

Two opposing forces run through these entries. The package keeps widening its coverage — ChEMBL in 1.2.0, LIPID MAPS and SwissLipids identifiers via Wikidata, structure images, Mol export — while the open, unauthenticated end of the chemical web keeps contracting. The other consistent thread is interface harmonisation: successive releases have converged the get_* functions on the same query and from arguments, tibble returns, and CAS reformatting, so the package feels like one interface rather than a dozen wrappers.

◆ Prediction

Expect further defunct functions and URL repairs as more providers move behind keys or shut down, alongside occasional additions of sources that remain open. The entries show no sign of a general credential-management layer, which is what a package facing this trend would eventually need.
