What is chromer?

A chromosome-count database client that only ever ships when the upstream API moves.

chromer is a thin R client for the Chromosome Counts Database. Every release in the past three years is maintenance: a new maintainer and licence change in 0.3, test-skipping when the upstream service is down in 0.4, and two separate releases whose entire content is that the database's URL changed again. The current 0.10 points at ccdb.tau.ac.il/services/.

What is taxizedb?

Stopped trusting the cloud to prepare its taxonomic databases and does the conversion locally.

taxizedb queries taxonomic databases locally rather than through rate-limited web APIs, which is what makes it usable for millions of name lookups. Version 0.2.0 established the current design: every source stored as SQLite, no credentials or ports needed, plus name-to-ID mapping functions and ports of the core taxize verbs. The most recent release changes how those databases arrive — instead of downloading a preprocessed SQLite file from the cloud, db_download_*() now fetches raw data and converts it locally for every source, because the cloud path kept breaking.

A chromosome-count database client that only ever ships when the upstream API moves.

◆ Current state

chromer is a thin R client for the Chromosome Counts Database. Every release in the past three years is maintenance: a new maintainer and licence change in 0.3, test-skipping when the upstream service is down in 0.4, and two separate releases whose entire content is that the database's URL changed again. The current 0.10 points at ccdb.tau.ac.il/services/.

◆ Where it's heading

The package is functionally complete and externally driven — its release cadence is a record of the CCDB's hosting history rather than of any development plan. The defensive work in 0.4, which added an internal check for whether the database is down and skips tests accordingly, shows the maintainer treating upstream instability as the permanent condition rather than an incident.

◆ Prediction

The next release will most likely be triggered by another CCDB endpoint or format change; nothing in the history suggests new functionality is planned.

Stopped trusting the cloud to prepare its taxonomic databases and does the conversion locally.

◆ Current state

taxizedb queries taxonomic databases locally rather than through rate-limited web APIs, which is what makes it usable for millions of name lookups. Version 0.2.0 established the current design: every source stored as SQLite, no credentials or ports needed, plus name-to-ID mapping functions and ports of the core taxize verbs. The most recent release changes how those databases arrive — instead of downloading a preprocessed SQLite file from the cloud, db_download_*() now fetches raw data and converts it locally for every source, because the cloud path kept breaking.

◆ Where it's heading

The package is trading convenience for independence. Each release removes another thing that has to be working elsewhere for the package to function: hosted database preparation is gone, and where a provider disappears the package documents it rather than pretending otherwise — db_download_tpl() is now defunct because The Plant List no longer exists, though previously downloaded copies still query fine. Release cadence is slow, with multi-year gaps and a maintainer handover in 2023.

◆ Prediction

Expect further releases to track data sources appearing and disappearing rather than adding features, since that has driven every recent change. Local conversion also shifts cost onto users, so build time and memory for the larger sources are the plausible next thing to need attention.
