Glossary¶
- cross-sectional¶
A data structure where the ‘innermost’ dimension is not a time dimension. Contrast with flat, time series.
- data flow¶
A collection of one or more data sets sharing the same structure.
- flat¶
A data set that is not grouped using SeriesKeys.
- information¶
Data and metadata.
- information model¶
A description of how information is organized, providing semantics: specific terms, their meanings, and their relationships. The SDMX IM is one information model.
- metadata¶
Information about data. For instance, [1.2, 3.4, 4.5] are data points, or observations. Metadata for these data might include:
what concept is being measured,
the units for the measurements,
labels in one or more dimensions for what the three points means, or
info about how the data was produced, and by whom.
- time series¶
A data structure where the ‘innermost’ dimension—the one that varies from one observation to the next—is time-related. Contrast with cross-sectional, flat.
