  CRAN metadata (crandb.r-pkg.org), PyPI JSON API, npm registry, and the USDAForestService GitHub
  organization. Version and published dates read from each registry's metadata endpoint on
  2026-09-10.

  The Forest Service ships no client SDK for any of its four HTTP APIs — the FIADB-API, the
  Research Data Archive web service, and the two ArcGIS REST servers are all called with a plain
  HTTP client, and the FIADB-API docs illustrate exactly that with hand-rolled `requests` (Python)
  and `httr` (R) examples rather than a library. What the agency does publish on a registry is its
  scientific tooling: two CRAN packages that read Forest Inventory and Analysis data, maintained
  out of the agency's own GitHub organization. They are first-party agency software but they are
  not clients for the web APIs profiled here, and they are recorded as such.

      Forest Inventory ESTimation and Analysis — estimation tool for analysts working with
      sampled data from the FIA program. Authored by Forest Service Rocky Mountain Research
      Station scientists (Frescino, Moisen, Patterson) and hosted in the agency's own GitHub org.

    note: >-
      Reads and estimates from FIA data; it is not a client for the FIADB-API HTTP surface.
      Registry URL field resolves to github.com/USDAForestService, which is how first-party
      status was established.

      Third-party Python library for Forest Inventory and Analysis data analysis.
    note: >-
      NOT first-party. Recorded because it is the most current community client in the FIA space
      and a reader will meet it; its project URLs resolve to github.com/mihiarc, not to the
      USDAForestService organization, so official is false.
unpublished_first_party_software:
  - name: ForestVegetationSimulator
    url: https://github.com/USDAForestService/ForestVegetationSimulator
    note: >-
      Growth-and-yield modelling software distributed as source and installers from the agency's
      GitHub org and website; no package-registry release, so no version/published fields can be
      read from a registry endpoint.
  - name: FSvolLib
    url: https://github.com/USDAForestService/FSvolLib
    note: Volume/biomass estimation library, source-distributed only, no registry release.
