… in CDM-based model - Introduced the Overviews construct as a hierarchical CDM-based model for representing multiscale data. - Defined conceptual elements: OverviewSet, OverviewLevel, and optional zoom_level. - Clarified structural layout using CDM entities (groups, variables, attributes). - Added formal schema for the multiscales property describing overview hierarchy, levels, and alignment. - Updated examples to include coordinate variables, auxiliary variables, and parent-level multiscales metadata. - Improved wording for clarity, precision, and consistency with CDM terminology.
(Recommended) Resolution of the data at this level, expressed as the physical size of one cell in coordinate units (e.g. metres or degrees). This property allows clients such as map viewers to select the most appropriate overview level for a given display scale. If expressed as an array, the order SHALL match the spatial axes (e.g. `[x, y]`).

This Overviews extension adapts the work proposed by @emmanuelmathot in EOPF Explorer – Data Model PR #41 to align with the GeoZarr specification.
The following key adaptations have been introduced:
groupandfrom_groupfields were replaced by the more neutral ìdand optionalpath` field, which preserves referential meaning without binding to a specific data model structure.tile_matrix_reffield was added to support datasets aligned with external map tiling definitions.
