EDIutils vs webchem: at a glance
What is EDIutils?
The EDI data client is being dragged through its repository's identity-system migration.
EDIutils is the R client for the Environmental Data Initiative repository. The last two releases are both consequences of changes at EDI rather than in the package: 2.0.0 rewired authentication for the new EDI Identity and Access Manager and made Distinguished Names defunct in favour of EDI-IDs, and 2.1.0 handles the deprecation of the old auth token. Earlier releases were small bug fixes against repository outages and endpoint changes.
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.

The EDI data client is being dragged through its repository's identity-system migration.
◆ Current state
EDIutils is the R client for the Environmental Data Initiative repository. The last two releases are both consequences of changes at EDI rather than in the package: 2.0.0 rewired authentication for the new EDI Identity and Access Manager and made Distinguished Names defunct in favour of EDI-IDs, and 2.1.0 handles the deprecation of the old auth token. Earlier releases were small bug fixes against repository outages and endpoint changes.
◆ Where it's heading
This is a client whose roadmap belongs to its server. Every meaningful release tracks something EDI changed — a deprecated endpoint, a resource outage breaking CRAN checks, and now a whole identity system — and the package's job is to absorb the churn while keeping the R interface stable. The 2.0.0 break was handled by pointing users at where to find their new EDI-ID rather than by papering over the change.
◆ Prediction
Expect continued follow-through on the IAM migration as the old auth token is fully retired, and further releases keyed to EDI service changes rather than to new client features.

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.
