  Live protocol probes of the Forest Service Research Data Archive web service, the FSGeodata
  ArcGIS REST/SOAP servers, and the agency Geospatial Data Discovery catalog, 2026-09-10.
note: >-
  Every entry below was established by fetching the surface and reading what it says about
  itself, not from a marketing claim. Where a standard was probed and is genuinely absent it is
  recorded with conforms:false so the absence is data rather than a silence.

  - id: oai-pmh-2.0
    name: Open Archives Initiative Protocol for Metadata Harvesting 2.0
    conforms: true
    evidence: https://www.fs.usda.gov/rds/archive/webservice/oaipmh?verb=Identify
    detail: >-
      HTTP 200, text/xml. Response is a valid OAI-PMH envelope declaring protocolVersion 2.0,
      repositoryName "Forest Service Research Data Archive", baseURL
      https://www.fs.usda.gov/rds/archive/webservice/oaipmh, earliestDatestamp 2016-02-22,
      deletedRecord "no", and gzip/deflate compression. Verbs Identify and ListMetadataFormats
      were both exercised.

  - id: oai-dc
    name: Dublin Core metadata (oai_dc) via OAI-PMH
    conforms: true
    evidence: https://www.fs.usda.gov/rds/archive/webservice/oaipmh?verb=ListMetadataFormats
    detail: >-
      ListMetadataFormats returns metadataPrefix "oai_dc" against schema
      http://www.openarchives.org/OAI/2.0/oai_dc.xsd.
  - id: fgdc-csdgm
    name: FGDC Content Standard for Digital Geospatial Metadata (FGDC-STD-001.1-1999)
    conforms: true
    evidence: https://www.fs.usda.gov/rds/archive/webservice/oaipmh?verb=ListMetadataFormats
    detail: >-
      The archive offers a second metadataPrefix, "fgdc", bound to schema
      http://www.fs.usda.gov/rds/rdaoaipmh/fgdc/fgdc-std-001.1-1999.xsd — the U.S. federal
      geospatial metadata standard, served alongside Dublin Core.
    domain_standard: true
    market: U.S. federal geospatial data
  - id: dcat-us-1.1
    name: DCAT-US 1.1 / Project Open Data catalog schema
    conforms: true
    evidence: https://data-usfs.hub.arcgis.com/api/feed/dcat-us/1.1.json
    detail: >-
      HTTP 200, application/json, ~2 MB. Body declares
      "@context": "https://project-open-data.cio.gov/v1.1/schema/catalog.jsonld",
      "@type": "dcat:Catalog" and
      "conformsTo": "https://project-open-data.cio.gov/v1.1/schema", carrying a dataset[] array of
      dcat:Dataset entries. This is the machine-readable inventory required of U.S. federal
      agencies under the OPEN Government Data Act, published by the Forest Service's own
      Geospatial Data Discovery site.

  - id: doi-crossref
    name: DOI persistent identifiers with Crossref funder registry cross-references
    conforms: true
    evidence: https://www.fs.usda.gov/rds/archive/webservice/product?id=RDS-2013-0001
    detail: >-
      Every product record carries a <doi> under the agency's 10.2737 prefix (e.g.
      https://doi.org/10.2737/RDS-2013-0001), and the /organizations endpoint returns a
      <crossref> block with Crossref Funder Registry ids (e.g. 100008144 for Alaska Department
      of Fish and Game) alongside each funder.

  - id: soap-wsdl-1.1
    name: SOAP 1.1 / WSDL 1.1
    conforms: true
    evidence: https://apps.fs.usda.gov/arcx/services/EDW/EDW_BasicOwnership_01/MapServer?wsdl
    detail: >-
      HTTP 200, text/xml, 290 KB. A complete WSDL 1.1 document, targetNamespace
      http://www.esri.com/schemas/ArcGIS/3.5.0, defining 55 portType operations and a
      soap:address of https://apps.fs.usda.gov/arcx/services/EDW/EDW_BasicOwnership_01/MapServer.
      Every service on both ArcGIS servers exposes the same ?wsdl surface.
  - id: esri-arcgis-rest
    name: Esri ArcGIS REST Services API (services directory + MapServer/FeatureServer resources)
    conforms: true
    evidence: https://apps.fs.usda.gov/arcx/rest/services?f=json
    detail: >-
      HTTP 200, application/json, currentVersion 11.5. Self-describing services directory listing
      nine folders (EDW, RDW_AdminAndOwnership, RDW_Climate, RDW_FIA_ForestAtlas,
      RDW_InventoryAndProducts, RDW_LandscapeAndWildlife, RDW_Wildfire, Utilities, wo_nrm_iweb);
      the EDW folder alone enumerates 144 MapServer services, each with a ?f=json resource
      document, layer list, capabilities string and error envelope.
    domain_standard: true
    market: geospatial web services
  - id: ogc-api-features
    name: OGC API - Features / OGC API common conformance
    conforms: false
    evidence: https://apps.fs.usda.gov/arcx/rest/services/EDW/EDW_BasicOwnership_01/MapServer?f=json
    detail: >-
      Probed and absent. The service resource documents return an empty supportedExtensions and a
      capabilities string of "Map,Query,Data" only. No /conformance document is served on either
      ArcGIS root.
  - id: ogc-wms
    name: OGC Web Map Service (classic OWS GetCapabilities)
    conforms: false
    evidence: https://apps.fs.usda.gov/arcx/services/EDW/EDW_BasicOwnership_01/MapServer/WMSServer?SERVICE=WMS&REQUEST=GetCapabilities
    detail: >-
      HTTP 400, "ArcGIS Server Error" — the OGC WMS server extension is not enabled on these
      deployments. Retried on EDW_ForestSystemBoundaries_01 and RDW_Wildfire with the same 400.
      The FSGeodata Clearinghouse Map Services page
      (https://data.fs.usda.gov/geodata/edw/mapServices.php) names ArcGIS REST, ArcGIS Online,
      Data.gov and the Hub site as the access routes and never mentions WMS, WFS or OGC, which
      corroborates the probe. Access to these layers is Esri-native or SOAP, not OGC.
  - id: oauth2
    name: OAuth 2.0
    conforms: false
    evidence: https://www.fs.usda.gov/.well-known/oauth-authorization-server
    detail: >-
      404. No authorization server metadata on any host; none of the four public APIs
      authenticates at all (see authentication/forest-service-authentication.yml).
  - id: rfc9457
    name: RFC 9457 Problem Details for HTTP APIs
    conforms: false
    evidence: https://apps.fs.usda.gov/arcx/rest/services/EDW/NOT_A_SERVICE/MapServer?f=json
    detail: >-
      No application/problem+json anywhere. The ArcGIS servers return a proprietary
      {"error":{"code":…,"message":…,"details":[]}} envelope with HTTP 200; the Research Data
      Archive and FIADB-API return HTML error pages. See errors/forest-service-error-catalog.yml.
