Weekly Report - Week 7 (July 6 - July 17, 2026)

Note: GSoC midterm evaluations took place July 6-10. I also lost a few days shortly after to a minor health issue requiring precautionary treatment, which limited hands-on time in the first half of this period.

I performed the following tasks during week 7:

Testing infrastructure bug -> resolved

  • Continued investigating the dummy-data/schema issue carried over from week 6. Traced through the database setup path, updating the psql initialization code to match the latest upstream commits and correcting a parameter crash along with an environment variable default in the generator flow.
  • Root cause turned out to be a database change from POSTGIS to TimescaleDB and that my working branch had gone unsynced with upstream for too long -> the actual fix had already landed upstream while I was independently trying to re-derive it. Pulling in the latest upstream changes resolved the issue outright.
  • With this resolved, the network-as-subcatalog architecture completed in week 6 is now fully verified end-to-end, and the STAC transformer is confirmed fully STAC-compliant. This closes out the last open item on the STAC layer.
  • Lesson going forward: keep the fork closely synced with upstream during active debugging, rather than assuming an issue is necessarily local to my own changes.

DCAT-AP 3.0 mapping -> migration started

  • Began migrating the DCAT-AP 3.0 field mapping work into the main connector repo. This mapping was largely done during pre-GSoC preparation in a standalone research repo, so this is primarily bringing it over and reconciling it against the current harvesting layer and network architecture rather than doing the mapping from scratch.
  • Started reviewing the existing mapping decisions (Datastream to dcat:Dataset, Thing to dcat:DatasetSeries, property-based gap-filling) against the network-subcatalog structure introduced in week 6, to confirm they still hold cleanly.

Details can be found in:

  • Fix commits: api/app/v1/connector/generator.py, database init scripts
  • DCAT mapping migration: in progress, moving from standalone repo into docs/STA-DCAT-AP-Transformation-Layer-Reference.md

What do I plan to do next week?

  • Finish migrating and reconciling the DCAT-AP mapping document against the current architecture.
  • Begin dcat_transformer.py implementation based on the finalized mapping.

Am I blocked on anything?

  • No blockages. The testing issue is resolved without needing mentor intervention, and the network architecture is now fully verified.
