| forecast_type | "forecast" or "hindcast | ""forecast" | " | "forecast" | To identify the type of data |
| history | Each line should begin with a timestamp indicating the date and time of day when the program was executed CF: Free Text |
| To record relevant information, such as the command history which led to this file being produced. Provides an audit trail for modifications to the original data.

commit, iso_lineage or lineage | Free text (ISO Lineage model 19115-2) | "Produced using CDS Toolbox v1.0" | Trace of the tools/scripts used. Either this attribute or the "history" attribute needs to include information about the versioning of the software used to create the data. This is related with some of the EQC activities (WP4 of QA4SEAS). ISO 19115-2 defines a linage model where this is been considered. | ||
| summary | Controlled Vocabulary: ACDD (highly recommended) | "Seasonal Forecast data produced by DWD as its contribution to the seasonal forecast activity of the Copernicus Climate Change Service (C3S).
