quantity

  • This page provides documentation for the quantity canonical concept dataset, which includes DSPL quantity concepts.

  • The dataset defines concepts like amount, magnitude, fraction, ratio, index, rate, and change rate, each with specific properties and attributes.

  • Concepts within the dataset are linked to external namespaces such as unit, geo, and time to provide further context.

  • A complete XML file of the dataset is available for download and review.

  • The dataset leverages a base "quantity" concept with attributes like unit, significant digits, and decimal places for representing numerical quantities.

This page documents the quantity canonical concept dataset. The complete XML file is also available for review.
