bcdata vs surveycore
A side-by-side editorial comparison of bcdata and surveycore — release velocity, themes, recent moves, and the top alternatives to consider.
bcdata vs surveycore: at a glance
What is bcdata?
The R gateway to B.C.'s data catalogue, mostly busy keeping pace with the servers behind it.
bcdata searches the British Columbia Data Catalogue and pulls records from it, including spatial layers retrieved through WMS and WFS with dplyr-style filtering translated into CQL queries sent to the server. The recent releases are small and corrective: 0.5.3 fixes malformed CQL generated by geometry predicates such as INTERSECTS, which the server had been rejecting outright, and 0.5.2 drops a leaflet extension dependency in favour of a base leaflet call. Cadence is a few releases a year.
What is surveycore?
surveycore declared its API stable with every survey design type covered.
surveycore is the estimation engine of a two-package survey stack, handling design objects and variance estimation while surveytidy supplies the dplyr verbs on top. The June release marks it 1.0.0 and states the API is complete and stable across Taylor series linearization, replicate weights, two-phase and non-probability designs, with means, totals, frequencies, quantiles, ratios, correlations, regression, t-tests, ANOVA and effective sample size all in place.

bcdata
0.0INFRA · APIS
The R gateway to B.C.'s data catalogue, mostly busy keeping pace with the servers behind it.
◆ Current state
bcdata searches the British Columbia Data Catalogue and pulls records from it, including spatial layers retrieved through WMS and WFS with dplyr-style filtering translated into CQL queries sent to the server. The recent releases are small and corrective: 0.5.3 fixes malformed CQL generated by geometry predicates such as INTERSECTS, which the server had been rejecting outright, and 0.5.2 drops a leaflet extension dependency in favour of a base leaflet call. Cadence is a few releases a year.
◆ Where it's heading
Almost everything in this window is a response to something changing on the other side of the connection: a CKAN 2.9 upgrade that stopped search and listing functions returning complete results, WMS and WFS capability requests that cannot be relied on, dbplyr tightening the rules for local evaluation, and general catalogue-side churn. The package's own interface has been stable since the 0.4.0 change that required local() around locally-evaluated filter calls, and the work since has gone into keeping that stable interface working rather than extending it.
◆ Prediction
Expect the same pattern: targeted fixes as the catalogue and its CKAN, WMS and WFS layers change, with occasional dependency pruning of the kind 0.5.2 did. Nothing in these entries points toward a 0.6 or a change in what the package covers.
surveycore
0.0INFRA · APIS
surveycore declared its API stable with every survey design type covered.
◆ Current state
surveycore is the estimation engine of a two-package survey stack, handling design objects and variance estimation while surveytidy supplies the dplyr verbs on top. The June release marks it 1.0.0 and states the API is complete and stable across Taylor series linearization, replicate weights, two-phase and non-probability designs, with means, totals, frequencies, quantiles, ratios, correlations, regression, t-tests, ANOVA and effective sample size all in place.
◆ Where it's heading
The last months before 1.0.0 were spent making the awkward designs behave like the ordinary ones. Non-probability designs gained jackknife replicate schemes and got their bootstrap repweights routed through the replicate-weight variance estimator in survey_glm(), matching every other estimation function. The survey_collection abstraction — several surveys treated as one pseudo-data-frame — was tightened rather than extended: divergent grouping across members now errors instead of stitching a patchwork with bind_rows(), and the missing-variable argument was renamed and given a stored default on the collection itself. A documentation audit before 1.0.0 turned up six dispatch and print bugs and corrections across forty-plus files, which is the kind of thing that surfaces when an API is being frozen rather than extended.
◆ Prediction
A declared-stable API means the next releases should be additive or corrective rather than breaking, and the pre-1.0.0 pattern of breaking renames should stop. The tight version pinning between the two packages means surveytidy releases will keep following surveycore's.

Frequently asked questions
What is the difference between bcdata and surveycore?
They serve adjacent needs but don't currently overlap on shipped themes. bcdata and surveycore 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 bcdata better than surveycore?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. bcdata and surveycore are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
