FREPJ-Z: Freshwater Plankton in Japanese Lakes and Reservoirs (I. Zooplankton)

intermediate validation build (v1.2) — this repository is the FREPJ-only intermediate testing/validation build. It is deliberately distinct from the frozen, immutable project-oceania/planktonzilla-17M composite (which is NOT modified by this build) and from the forthcoming full composite planktonzilla-v1.2.

Columns

The consolidated planktonzilla schema — image, the source provenance (dataset, original_label, original_path), the seven taxonomy ranks and label extras, the five external-ID columns, the metadata columns (Latitude, Longitude, timestamp, …) and the per-image license / license_url — plus, as in every planktonzilla source, one JSON object per image in custom_metadata holding what only this source knows:

• custom_metadata: {"magnification": "40" | "100", "site": "<sampling-site token as published upstream>"}.
• timestamp: the upstream sampling date normalized to ISO YYYY-MM-DD. The source column is hand-typed free text; values that cannot be read without guessing (about 1.9% of the images) are null. Latitude / Longitude are resolved from the site token for about 87% of the images and null for the rest — never a guessed coordinate.
