qcTAF vs StreamCatTools: at a glance
What is qcTAF?
qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time
qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.
What is StreamCatTools?
StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet
StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.

qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time
◆ Current state
qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.
◆ Where it's heading
Each release converts more of the informal completeness checklist into executable checks. February added relative-path and script-existence checks; late February added data and software declaration checks plus two new completeness criteria covering initial-versus-boot data identity and DATA.bib declarations; May added qc.any.scripts.exist() and made qc.only.relative.paths() treat /home/ as absolute. Function naming is being revised as the set grows, with renames in every release so far.
◆ Prediction
With the naming churn ongoing and criteria still being added, the next release most likely continues both. The package appears to be tracking a moving definition of TAF completeness rather than a fixed spec.

StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet
◆ Current state
StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.
◆ Where it's heading
The newest release adds lc_get_watershed(), which returns a lake watershed as an sf feature by reading an S3-hosted, HUC2-partitioned GeoParquet dataset with DuckDB, optional HUC2 filtering, retries and multi-threading. That is a materially different access model from the web service the rest of the package uses. Alongside it, 0.10.0 added National Nutrient Inventory access and nitrogen/phosphorus budget plotting, extending the package past retrieval into presentation.
◆ Prediction
If the GeoParquet path proves faster and more reliable than the web service, migrating more retrieval functions onto it is the obvious next move. The entries do not say whether EPA intends to publish the full metric catalogue in that format.
