Metadata travels with data
Temperature, salinity, current and image records need calibration, sampling and instrument details. A successful archive transfer does not prove that the dataset is understandable.
Names identify files, checksums compare bytes and metadata explains meaning. Each performs a different job.
Versions should remain visible
Changes to scripts, parameters or cleaning rules can produce legitimate differences. A revised result should record why it changed and where it applies.
Interrupted transfers should preserve receiving status so that a partial copy is not mistaken for a complete dataset.
Access follows sensitivity
Open observations and restricted project material require different sharing rules. Contracts, privacy and collaboration agreements define access.
Support requests should never require private configurations, credentials, verification codes or unpublished research files.
