dc:description "Downloaded dataset_pollen_raw.csv from the public Dryad file link, hashed it, and grouped honey-bee rows by site, period, day and bee. The pollen-kind column was chosen by the pre-registered header priority. A load with two or more distinct pollen-kind values was mixed. The fraction was compared with 0 and 0.10.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 0.38645 fraction of scored honey-bee pollen loads with two or more pollen kinds (n = 1048). Interpretation: Aristotle's unit is one expedition ending at the hive. A corbicular pollen load collected from a forager is the usual measurement of the flowers visited on the trip that produced that load. Microscopy can under-count rare grains, so a mixed load is stronger evidence of inconstancy than a pure load is of perfect constancy. The claim names the bee in the honey context (the hive); Apis mellifera is the species scored. Flower kind follows the dataset's pollen morphotype or, if that column is absent, the next column on the priority list.";

Inconclusive with reason data-unavailable if the file cannot be retrieved, honey-bee rows cannot be identified, the grouping columns site, period, day and bee are missing, or no pollen-kind column can be identified by the priority list in the contract. A load is one unique combination of site, period, day and bee among rows whose species value, lowercased, is hb or contains mellifera or honey. A load is mixed if it has at least two distinct non-blank pollen-kind values; single-kind if it has exactly one; excluded if it has none.
