representation

Lexicon: eco.wonderland.workcell.common.data.defs
Type: string

• time-series: Series of sampled data. The data is reported for a specified number of samples and each sample is reported with a fixed period.
• value: Measured value of the sample data. If no representation is specified for a data item, the representation MUST be determined to be value.
• data-set: Reported value(s) are represented as a set of key-value pair. Each reported value in the data set MUST have a unique key.
• table: Two dimensional set of key-value pair where the entry represents a row, and the value is a set of key-value pair cell elements. A table follows the same behavior as the data set for change tracking, clearing, and history. When an entry changes, all cell elements update as a single unit following the behavior of a data set.

Note: It is best to use variable if the cell entities represent multiple semantic types. Each entry in the table MUST have a unique key. Each cell of each entry in the table MUST have a unique key. See representation in Observation Information Model, for a description of entry and cell elements.
