What is glydb?

glydb is pulling GlyGen's structure database onto the user's own disk.

glydb bundles glycan structure reference data and provides lookup helpers for compositions, structures, and species. The 0.6.0 release grew the bundled dataset to 19,436 GlyGen structures including non-intact glycans, and changed glytoucan_to_struc() to search that local data before falling back to the online GlyGen API. Version 0.4.0 added a confidence attribute that glyanno uses to rank candidate matches.

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.

glydb is pulling GlyGen's structure database onto the user's own disk.

◆ Current state

glydb bundles glycan structure reference data and provides lookup helpers for compositions, structures, and species. The 0.6.0 release grew the bundled dataset to 19,436 GlyGen structures including non-intact glycans, and changed glytoucan_to_struc() to search that local data before falling back to the online GlyGen API. Version 0.4.0 added a confidence attribute that glyanno uses to rank candidate matches.

◆ Where it's heading

The arc is from thin wrapper toward self-contained reference: the bundled data keeps growing, online lookups are demoted to fallbacks, and classification vocabularies are being adopted from GlyGen rather than invented locally. The other constant is chasing glyrepr, whose structure representation has changed enough times that regenerating the bundled indexes is a recurring release note.

◆ Prediction

Expect the bundled dataset to track further GlyGen and GlyTouCan releases, with the online API path continuing to narrow to accessions the local data does not cover.

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.
