How a machine reads this record

Documentation of the published retrieval path.

Reference documentation · not a request log

Entity → canonical URL → record.json → field → provenance

These are the paths and properties this record actually publishes. Nothing on this panel ran, and no query or answer is depicted.

A consumer that finds value: null receives null. MeasuredWatch does not fill it.

01Entity

The record is identified by brand, model and reference, and carries a stable record ID.

brand.name   "Omega"
model        "Speedmaster 38"
mpn          "324.30.38.50.04.001"
recordId     "MWR-000217"

02Canonical
The canonical page embeds the same document in a <script type="application/ld+json"> tag, server-rendered.
```
https://www.measuredwatch.com/watches/omega/speedmaster-38-324-30-38-50-04-001
```

03Endpoint

The same document is served standalone. Response headers set by the route:

GET https://www.measuredwatch.com/watches/omega/speedmaster-38-324-30-38-50-04-001/record.json
Content-Type: application/ld+json; charset=utf-8
Access-Control-Allow-Origin: *
Link: <https://www.measuredwatch.com/watches/omega/speedmaster-38-324-30-38-50-04-001>; rel="canonical"

04Field
Each tracked field is one PropertyValue in additionalProperty, keyed by propertyID. Values are published as the source text; no unit conversion is applied.
```
propertyID  "diameter"
value       "38 mm"
unitText    "mm"
```

05Provenance

Provenance travels with the field, not the page.

measuredwatch:provenance  "published"
measuredwatch:sourceType  "manufacturer"
measuredwatch:sourceUrl   "https://www.omegawatches.com/en-us/watch-omega-speedmaster-38-co-axial-chronometer-chronograph-38-mm-32430385004001"
measuredwatch:checkedAt   "2026-09-15T17:57:21.434+00:00"

06Unknown

A field with no supported value is still published, explicitly, so absence is machine-readable.

propertyID            "crown_diameter"
value                 null
measuredwatch:status  "unknown"
