qualtRics vs ReLTER: at a glance
What is qualtRics?
qualtRics moved its contact functions onto XM Directory days before the old endpoints died.
qualtRics is the R client for the Qualtrics v3 API — fetching survey responses, definitions, distributions, and contact lists into tidy data frames. Version 3.3.0 migrated all_mailinglists() and fetch_mailinglist() from the deprecated Research Core Contacts endpoints to XM Directory, ahead of Qualtrics retiring the old ones on June 30, 2026. Authentication and directory discovery are handled automatically, but the new endpoints return a different data shape, so column names changed. Before that, releases had been steady maintenance for two years, mostly around how survey response archives are unpacked.
What is ReLTER?
An interface to Europe's long-term ecosystem research network that went quiet after 2.0.
ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.

qualtRics
0.0ANALYTICS
qualtRics moved its contact functions onto XM Directory days before the old endpoints died.
◆ Current state
qualtRics is the R client for the Qualtrics v3 API — fetching survey responses, definitions, distributions, and contact lists into tidy data frames. Version 3.3.0 migrated all_mailinglists() and fetch_mailinglist() from the deprecated Research Core Contacts endpoints to XM Directory, ahead of Qualtrics retiring the old ones on June 30, 2026. Authentication and directory discovery are handled automatically, but the new endpoints return a different data shape, so column names changed. Before that, releases had been steady maintenance for two years, mostly around how survey response archives are unpacked.
◆ Where it's heading
This package's roadmap is set by Qualtrics, not by its maintainers, and the release history reads as a sequence of accommodations — endpoint changes, retired APIs, and edge cases in exported files. The team's own recurring theme is reducing surprise: caching was removed from fetch_survey() in 3.2.0 so results are never stale, error handling was standardized on retry semantics, and column mappings were made inspectable via extract_colmap(). Feature additions, when they come, are new endpoints wrapped rather than new abstractions.
◆ Prediction
With the Contacts migration complete, the next likely work is bringing the remaining Research Core-era functions onto XM Directory equivalents before Qualtrics retires more of the old surface.
ReLTER
0.0ANALYTICS
An interface to Europe's long-term ecosystem research network that went quiet after 2.0.
◆ Current state
ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.
◆ Where it's heading
The visible arc runs from a scattered set of getSite* functions to a reviewed, documented package, and then stops. The absence of notes on the 2.0.0 tag makes it impossible to say from this feed what that major version changed, and the three-year silence afterwards is the more informative signal. What the package does remains useful — the eLTER data it wraps has no other R interface — but the release history gives no evidence of active development.
◆ Prediction
Nothing in these entries supports a confident prediction about future releases; the feed shows a major version with no notes followed by silence. Whether the package is dormant or simply publishing releases elsewhere cannot be determined from what is here.
