bcdata vs mpactr
A side-by-side editorial comparison of bcdata and mpactr — release velocity, themes, recent moves, and the top alternatives to consider.
bcdata vs mpactr: 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 mpactr?
mpactr spent two spring releases normalizing case in metadata after users kept tripping on it.
mpactr filters mass-spectrometry peak tables — removing contaminants, ion duplicates and low-reproducibility features before downstream metabolomics analysis — with a data.table and Rcpp core. Development is slow and the recent releases are small. The May pair both address the same friction: column names and imported table names arriving in inconsistent case and failing to match.

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.
mpactr
0.0INFRA · APIS
mpactr spent two spring releases normalizing case in metadata after users kept tripping on it.
◆ Current state
mpactr filters mass-spectrometry peak tables — removing contaminants, ion duplicates and low-reproducibility features before downstream metabolomics analysis — with a data.table and Rcpp core. Development is slow and the recent releases are small. The May pair both address the same friction: column names and imported table names arriving in inconsistent case and failing to match.
◆ Where it's heading
The package is stabilizing its input contract rather than growing its filtering methods. Metadata column names are now forced lowercase inside import_data() regardless of how the file was written, imported peak_tables names not present in the injection column are lowercased too, and get_meta_data() was renamed to get_metadata() in the same pass. Before that the work was infrastructural — Rcpp introduced to speed up filtering, data.table moved from Depends to Imports, and memory errors cleared so the package passes Valgrind and both sanitizers. Note the earliest entry compares against a v1.0.0 tag that precedes 0.1.0 in the repository, so version ordering in this feed is not reliable.
◆ Prediction
The case-normalization work has now touched both metadata columns and peak table names across two consecutive releases, which suggests the input-matching problem is not fully closed and a third pass is plausible. Nothing in these entries points to new filtering methods.
