Walkthrough

Decide whether Zarr, NetCDF, or HDF5 is ready

A preview-only maturity review for multidimensional formats. It is deliberately non-runnable and non-GA: server source evidence exists, but no JavaScript adapter or public end-to-end canary closes the path.

Server contract first

Review multidimensional format maturity before choosing an executable coverage workflow

source-preview

Fixture endpoint: No runnable endpoint admitted
Service manifest key: Not admitted
Evidence: unavailable at honua-server:61b7038e1887c98131aa217b6f0ae7869356a1f3 + 639d37449fb8da5e9df4b12b7641ba4c6c5ac581
Server version: Pinned source evidence only; no admitted public deployment
Owner: honua-server owns server maturity; honua-sdk-js owns any future public client; honua-samples owns this truthful curriculum projection
Support: Preview-only architecture guidance; not a support claim

Authentication

No runnable request is admitted. Existing registration evidence is administrative and must not be presented as anonymous read support.

Cancellation

Not applicable because this page executes no request.

Errors

Treat unavailable, metadata-only, experimental, and missing-canary states as release blockers; never fall back to a browser full-file download.

zarr-v2-v3

N/A No public endpoint admitted by this walkthrough

Registration, bounded subset internals, CoverageJSON, WCS fixtures, and datacube components are source evidence only. They do not create a public client workflow.

contract-only

netcdf4

N/A Administrative registration and build-optional conversion evidence only

Registration metadata and optional GDAL conversion do not prove readable NetCDF variables or subsets.

  "endpoint": "Administrative registration and build-optional conversion evidence only",
  "payload": {

contract-only

geospatial-hdf5

N/A Administrative registration and conversion architecture evidence only

HDF5 is not inherently geospatial. Only a future documented coverage mapping could enter scope.

{
  "method": "N/A",
  "endpoint": "Administrative registration and conversion architecture evidence only",
  "payload": {
    "state": "withheld",

Semantic assertionThe page offers no Run action, executable code, live claim, GA badge, invented API, or full-file browser fallback; use the supported Coverages/WCS recipe for current runnable multidimensional curriculum.

Evidence

honua-sdk-js@d68f221a3ee49b86f06f0d587faf2c627263283d/config/multidimensional-format-maturity.v1.json
Zarr server evidence pinned to honua-server@639d37449fb8da5e9df4b12b7641ba4c6c5ac581
NetCDF-4 and geospatial HDF5 server evidence pinned to honua-server@61b7038e1887c98131aa217b6f0ae7869356a1f3

Limits and blockers

Zarr client and end-to-end states are unavailable; the server state is experimental and lacks a positive public canary.
NetCDF-4 and geospatial HDF5 client and end-to-end states are unavailable; server evidence is metadata-only and build-optional.
There is no public JavaScript adapter, runnable sample, stable bounded variable/subset contract, immutable live fixture, Studio action, or CLI command for these formats.
Geospatial HDF5 means only datasets that map to a documented coverage model; arbitrary HDF5 group browsing is out of scope.

Server references

Ordered job walkthrough

Complete the lifecycle deliberately.

contract-onlySeparate client, server, and end-to-end maturity
Read each layer independently; do not promote server source evidence into a client or deployed compatibility claim.
Expected: Zarr resolves to unavailable / experimental / unavailable; NetCDF-4 and geospatial HDF5 resolve to unavailable / metadata-only / unavailable.
contract-onlyCheck the publication gates
Require immutable fixtures, stable versioned metadata and bounded subset operations, deployed canaries, resource budgets, typed client errors, and reviewed package exports.
Expected: Every missing gate remains visible and prevents a runnable or GA claim.
availableChoose the current executable path
Use the separate fixture-backed OGC API Coverages / WCS quickstart when the learning task is a bounded coverage subset and MapLibre handoff.
Expected: A runnable standards-based coverage example without implying native Zarr, NetCDF, or HDF5 client support.
plannedRevisit only after evidence lands
Add format-specific executable curriculum only after the corresponding SDK export, fixture, live service, error, cancellation, and budget receipts pass.
Expected: A future runnable walkthrough is evidence-gated rather than inferred from architecture.

Final assertionThe page offers no Run action, executable code, live claim, GA badge, invented API, or full-file browser fallback; use the supported Coverages/WCS recipe for current runnable multidimensional curriculum.
