Submitting Fonteum datasets to Google Dataset Search + DCAT-US 3.0

The list below documents surfaces intended to emit schema.org/Dataset JSON-LD. Inspect the rendered response and current submission rules before relying on a listing. This page is an operator runbook, not proof that a crawler indexed a surface.

Dataset surfaces

8 surfaces emit Dataset JSON-LD. The /data surface aggregates the entries represented by that catalog in DCAT-US 3.0 format. Its coverage is incomplete relative to the active production source registry.

  • https://fonteum.com/data
    DataCatalog

    DCAT-US 3.0 aggregate catalog for the dataset entries represented by this surface. It is not a complete enumeration of the active production registry.

  • https://fonteum.com/research
    DataCatalog (per-study Dataset entries)

    Catalog of published research entries represented by the current research registry. A study page can emit its own Dataset record when that page supplies the required metadata.

  • https://fonteum.com/freshness
    Dataset + 6 DataFeed

    A six-feed healthcare subset, not the full active production registry. It exposes available row-count observations and dates for the feeds represented there; a current observation is not proof that an upstream release or ingest completed that day.

  • https://fonteum.com/trust/integrity
    DataCatalog (per-attestation Dataset entries)

    Stored snapshot-attestation entries represented on the integrity surface. Attestation coverage is incomplete, and an attestation applies only to its identified snapshot object; it does not sign every provenance fact.

  • https://fonteum.com/identity
    Dataset + WebAPI

    Supported provider-identity relationships where the participating rows publish a compatible key (for example NPI or CCN). The Dataset record does not imply that every NPPES, PECOS, LEIE, HRSA, or facility row is linked.

  • https://fonteum.com/search
    Dataset + WebSite + SearchAction

    Public search over supported healthcare-provider records. The Dataset.potentialAction describes the available SearchAction; it is not a claim of whole-registry or whole-market coverage.

  • https://fonteum.com/providers/<npi>
    ProfilePage + Dataset-backed provider record

    Public provider records backed by supported healthcare source families. Each surface states its available fields and limitations.

  • https://fonteum.com/care-compare/<module>
    Dataset (one per Care Compare module)

    Per-Care-Compare-module Dataset records (nursing-homes, home-health, hospice, dialysis, asc).

One-time submission steps

1. Google Dataset Search

Submit each Dataset URL via Google Search Console > URL Inspection > Request Indexing. Once a single Dataset URL is indexed, Google Dataset Search picks up the rest from the sitemap. The fastest path is to submit /data — its DataCatalog record links the Dataset entries represented by that catalog.

Confirm via search.google.com/search-console > URL Inspection > paste https://fonteum.com/data > Request Indexing

2. data.gov DCAT ingestion (federal-agency catalogs)

data.gov accepts DCAT-US 3.0 catalogs via its CKAN harvester. Submit /data to catalog.data.gov via the publisher form. Once registered, agency catalogs (NIH ODSS, AHRQ research portal, CMS data.gov listings) auto-harvest the catalog on their published cadence.

3. Verify with Google Rich Results Test

Before broad submission, verify each Dataset URL renders valid structured data:

https://search.google.com/test/rich-results?url=https://fonteum.com/data

Replace the URL parameter with each surface from the list above. The tool flags any required-field gaps that would block ingestion. The launch gate dataset-jsonld:every-surface-validates catches the same gaps in CI.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
