glydb vs igoR
A side-by-side editorial comparison of glydb and igoR — release velocity, themes, recent moves, and the top alternatives to consider.
glydb vs igoR: at a glance
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 igoR?
igoR reached 1.0.0 with no user-visible change, then spent three releases on AI-assisted cleanup
igoR provides access to Intergovernmental Organizations (IGO) databases from the Correlates of War project. The dataset and public API have been stable for years; recent releases are almost entirely maintenance. 1.0.0 in January 2026 raised the minimum R version to 3.6.0 and stated explicitly that users would see no change.

glydb
0.0ANALYTICS
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.
igoR

igoR reached 1.0.0 with no user-visible change, then spent three releases on AI-assisted cleanup
◆ Current state
igoR provides access to Intergovernmental Organizations (IGO) databases from the Correlates of War project. The dataset and public API have been stable for years; recent releases are almost entirely maintenance. 1.0.0 in January 2026 raised the minimum R version to 3.6.0 and stated explicitly that users would see no change.
◆ Where it's heading
Development has shifted to documentation and internal consistency, and the mechanism is notable: 1.0.2 and 1.0.3 both describe AI-assisted editing and refactoring, part of a sweep the same maintainer ran across several packages in mid-2026. The one substantive fix in the window is igo_dyadic() computing dyadid from both state codes as documented. Everything else is dependency bumps and message wording.
◆ Prediction
With the internals refactored and documentation reviewed, further releases are likely to track upstream Correlates of War data updates rather than change the API. The entries give no indication of a pending data revision.

Frequently asked questions
What is the difference between glydb and igoR?
They serve adjacent needs but don't currently overlap on shipped themes. glydb and igoR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is glydb better than igoR?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. glydb and igoR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
