Namespace EncDotNet.S100.Hdf5

CompoundMemberInfo: Describes a single member of a compound HDF5 datatype as observed on disk. Used to project RawCompoundDataset rows into product-specific value types when member naming or numeric width varies between producers.

ExceptionMessageFormatter: Shared message-text helpers used by S100DatasetSchemaException, S100DatasetNotSupportedException, and dataset readers that need to construct a "not yet supported" message with the canonical four-piece shape (product, file, feature, spec ref).

Hdf5DeclaredExtent: Reads the extent an S-100 HDF5 dataset declares, for the axis-order check (AxisOrderCheck, issue #650).

Hdf5RequiredAttributeExtensions: Extension methods that translate PureHDF's Could not find attribute '{name}' failure (and equivalent "missing" exceptions from other backends) into typed S100DatasetSchemaExceptions carrying spec context. Reader implementations call these for attributes that are required by the spec; optional attributes should still be guarded with AttributeExists(string).

RawCompoundDataset: A compound dataset returned in raw form: the bytes are laid out exactly as on disk (record-major), and the members describe where each field lives within a record. Callers project rows into their own value types so that small spec-conforming variations (member renames, numeric width changes) can be tolerated without changing public value-struct layouts.

S100DatasetNotSupportedException: Thrown when an S-100 dataset uses an optional spec feature (data-coding format, CRS variant, attribute encoding, etc.) that the current reader does not yet implement. Distinct from S100DatasetSchemaException: the file is conforming; it just exercises a region of the spec we haven't built yet.

S100DatasetSchemaException: Thrown when a required HDF5 attribute, dataset, or group is missing from a location that the S-100 spec requires it on, or is present but malformed in a way that cannot be reasonably tolerated. The exception carries the product, file (when known), the HDF5 group path that was being read, the offending attribute/dataset name (when applicable), and a citation into the relevant spec section so that callers can produce actionable diagnostics.

IHdf5File: Abstraction over an HDF5 file, providing access to the root group.

IHdf5Group: Abstraction over an HDF5 group, providing navigation and typed data access.

CompoundMemberKind: Classifies a compound member's on-disk numeric kind so callers can project it into a target .NET type without recompiling against PureHDF types.
