What is glcdp?

glcdp reaches 1.0.0 with a stable schema contract behind its data explorer.

glcdp imports light-logger data packages published to the GLC standard, driven by declared schemas rather than format-specific readers. 0.9.3 added glc_explore(), a Shiny application for browsing the registry and exporting an annotated reproducible script. 1.0.0 promotes schema 3.0.2 to the default and primary stable import contract and makes schema-declared variable types and factor-level order drive the import itself.

What is trackeR?

Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.

trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.

6.3

glcdp reaches 1.0.0 with a stable schema contract behind its data explorer.

◆ Current state

glcdp imports light-logger data packages published to the GLC standard, driven by declared schemas rather than format-specific readers. 0.9.3 added glc_explore(), a Shiny application for browsing the registry and exporting an annotated reproducible script. 1.0.0 promotes schema 3.0.2 to the default and primary stable import contract and makes schema-declared variable types and factor-level order drive the import itself.

◆ Where it's heading

The package is serving two audiences from one model. Programmatic users get glc_collect(), extract_metadata() and add_metadata(), with imports that reject file groups whose factor labels or level order disagree. Interactive users get an Explorer that filters by device, wearing position, modality, role and data state, pages large inventories at 100 rows, and caches remote metadata for immutable revisions. Schemas 1.0.0 and 2.0.0 stay reachable as barebones legacy paths.

◆ Prediction

With 3.0.2 named the primary stable contract and the older schemas explicitly labelled legacy, retiring the barebones paths is the most likely next structural move. The notes give no indication of work beyond the current schema line.

0.0

Fitness-tracking analysis in slow maintenance, still absorbing upstream breakage.

◆ Current state

trackeR reads GPS and fitness-tracker files in TCX, GPX and JSON form and turns them into session data, distribution and concentration profiles, and route plots. Feature work concentrated in the 1.5 series in 2019; the two releases since are corrective. The latest swaps the plot layout dependencies for patchwork and fixes plot_route() returning nothing.

◆ Where it's heading

Recent releases track other people's changes: ggmap moving to Stadia maps, gridExtra giving way to patchwork, a cadence field being read into the wrong column. The 2019 entries are where the analysis surface was built out, with cumulative elevation gain, compressed file reading and elevation-noise thresholds, and it has not moved much since.

◆ Prediction

Expect the next release to be another compatibility or parsing fix rather than a new metric.
