Namespace EncDotNet.S100.Datasets.Pipelines.Catalog

CapDatasetData: The catalog payload of a CAP file: its warning areas, resolved and timed, and the dataset metadata the catalog entry is built from.

DatasetCatalogNotReadyException: Thrown by an LoadAsync(string, string?, CancellationToken) implementation whose host load path is not yet initialised (e.g. the desktop viewer's dataset loader before the main window has wired it up).

DatasetIdJsonConverter: Serialises DatasetId as a bare JSON string so that the identifier round-trips symmetrically: every tool accepts a plain string datasetId argument, and every tool result therefore emits the same plain string rather than a wrapped {"value":"…"} object.

DatasetLoadOutcome: The outcome of a LoadAsync(string, string?, CancellationToken) call.

FileDatasetCatalog: A read-only, file-backed IDatasetCatalog built once from a fixed set of dataset files — the headless counterpart to the viewer's live catalog, used by the CLI identify command to run the same pick services (IdentifyFeaturesService / SampleCoverageService) the MCP surface exposes, without an open viewer or MCP server.

LoadedDatasetData: Discriminated union over the typed payloads that a LoadedDataset may carry. Each spec contributes either a typed DataModel projection (vector products) or a coverage source (HDF5-encoded coverage products).

LoadedDatasetProjector: Projects a single S-100 dataset into the typed LoadedDataset carried by an IDatasetCatalog.

ProductDatasetData: The payload of a product that has no built-in LoadedDatasetData variant — a host's own product, or a non-S-100 format such as GRIB2 — returned by its OpenData. It carries the dataset's own DatasetMetadata, from which LoadedDatasetProjector takes the catalog entry's spec, bounds and time coverage, so the projector needs no case for the product. A coverage product's payload also implements ICoverageSampler, so the sample_coverage tools sample it with no tool changes.

S104StationSeriesData: S-104 Water Level station-series dataset (dcf8 — time series at fixed stations; see S-104 Edition 2.0.0 §10.2.3 / §10.2.7).

S111StationSeriesData: S-111 Surface Currents station-series dataset (dcf8 — time series at fixed stations; see S-111 Edition 2.0.0 §10.2.3 / §10.2.7).

WeatherGridDatasetData: The catalog payload of a weather grid dataset (NetCDF-CF or GRIB2): a ProductDatasetData that describes itself and samples its grid, so sample_coverage and sample_coverage_along answer with wave heights and winds and their units with no MCP change (design note weather-sources.md §8.8).

IDatasetCatalog: Read-only view onto the set of datasets currently loaded by a host (e.g. a viewer, CLI, or headless service).

ILoadedDatasetProjection: Implemented by an IDatasetProcessor that can yield the query-tool payload for its already-parsed dataset, so a host can project a LoadedDataset from a resident processor rather than re-parsing the dataset bytes a second time.

IMutableDatasetCatalog: The write side of an IDatasetCatalog: a catalog whose contents a mutating host can change in-process. Backs the open_dataset, close_dataset, and close_all_datasets tools.

ITimeSteppedDatasetData: A catalog payload whose dataset has time steps of its own: a weather grid's valid times, or the times a CAP file's warnings start and end. The list_time_steps tool reads it, so a product that isn't S-104 or S-111 lists its steps without a change to the tool.

DatasetCatalogChangeKind: The kind of change reported by an IDatasetCatalog.
