kwb.geosalz vs tulpaObs: at a glance
What is kwb.geosalz?
A research-project workflow package where the interesting work is in the plumbing.
kwb.geosalz documents the data workflows for GeoSalz, a groundwater salinisation project run by Kompetenzzentrum Wasser Berlin, packaging retrieval, checking and plotting steps as reproducible R code. The current release replaces an SFTP dependency with curl and reports listing files on the SFTP server running 50 to 100 times faster. Earlier releases added data-availability workflows against Berlin's open water portal and functions for well-field abstraction figures.
What is tulpaObs?
An occupancy-modeling package that just deleted its own duplicate vocabulary for diagnostics.
tulpaObs is the ecological occupancy and abundance modeling layer built on the tulpa engine, releasing at high frequency and with version numbers that do not advance monotonically in publication order. The current window covers three strands: a breaking consolidation of its diagnostic surface onto generics the engine now owns, the completion of simulation-based-calibration registration across all 27 model families, and a correctness fix that materially moves previously reported information criteria. Several releases exist only to pin a new engine version and record what that change does when measured from this side.

kwb.geosalz
0.0ANALYTICS
A research-project workflow package where the interesting work is in the plumbing.
◆ Current state
kwb.geosalz documents the data workflows for GeoSalz, a groundwater salinisation project run by Kompetenzzentrum Wasser Berlin, packaging retrieval, checking and plotting steps as reproducible R code. The current release replaces an SFTP dependency with curl and reports listing files on the SFTP server running 50 to 100 times faster. Earlier releases added data-availability workflows against Berlin's open water portal and functions for well-field abstraction figures.
◆ Where it's heading
Releases track the project's own data-collection reality rather than a software roadmap: new data source appears, a workflow is added; a transfer library becomes a liability, it is swapped out. The measurement-chain pipeline is the recurring subject, appearing in plotting fixes at 0.7.1 and the transport rewrite at 0.7.2. Cadence is roughly annual and the changelog is written for project members, which makes external readability secondary by design.
◆ Prediction
Expect the next release to follow the measurement-chain data as it accumulates, most likely more plotting or availability-checking work rather than new infrastructure.
tulpaObs
6.3ANALYTICS
An occupancy-modeling package that just deleted its own duplicate vocabulary for diagnostics.
◆ Current state
tulpaObs is the ecological occupancy and abundance modeling layer built on the tulpa engine, releasing at high frequency and with version numbers that do not advance monotonically in publication order. The current window covers three strands: a breaking consolidation of its diagnostic surface onto generics the engine now owns, the completion of simulation-based-calibration registration across all 27 model families, and a correctness fix that materially moves previously reported information criteria. Several releases exist only to pin a new engine version and record what that change does when measured from this side.
◆ Where it's heading
The package is systematically removing the parallel names it had accumulated for concepts owned elsewhere, and the registration work is closing rather than expanding — the SBC scope reached its final family in this window. Its cadence is tightly coupled to the engine's, to the point where the interesting content of some releases is a dependency floor plus a measurement. With the breaking rename and the registration scope both behind it, the surface work looks close to finished.
◆ Prediction
Expect the follow-on releases to be consolidation rather than expansion — registry branches, regenerated documentation, engine pins — with the next substantive move most likely a new model family beyond the original registration scope.
