CRediTas vs webchem: at a glance
What is CRediTas?
A CRediT author-statement generator that renamed itself, then went quiet for two years.
CRediTas turns a contributor-roles table into a CRediT Author Statement for a paper. The 0.2.0 release in April 2023 did the heavy lifting — package rename, a full object_verb() API rename, and output that drops straight into R Markdown or Quarto. The 0.3.0 release in August 2025 is the only activity since and carries no changelog text beyond a pointer to NEWS.md.
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.

A CRediT author-statement generator that renamed itself, then went quiet for two years.
◆ Current state
CRediTas turns a contributor-roles table into a CRediT Author Statement for a paper. The 0.2.0 release in April 2023 did the heavy lifting — package rename, a full object_verb() API rename, and output that drops straight into R Markdown or Quarto. The 0.3.0 release in August 2025 is the only activity since and carries no changelog text beyond a pointer to NEWS.md.
◆ Where it's heading
Development front-loaded a breaking cleanup during rOpenSci review and has coasted since. The design bet made in 0.2.0 — return a string for inline use rather than write a file — pointed the package at literate authoring workflows rather than at standalone scripts, and nothing since has moved away from it. The empty 0.3.0 note makes the current direction impossible to read from the feed.
◆ Prediction
Too little is published to call the next move; the 0.3.0 entry would need to carry its actual changes for the trajectory to be readable from the changelog at all.

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.

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.
