OpenAirframes — Data Source Notices
===================================

The LICENSE file covers the *code* in this repository. It does not cover the
*data* published in releases. Several upstream registries permit redistribution
only on condition that specific notices travel with the data. Those conditions
are reproduced below. This file is published as an asset on every release; anyone
redistributing a release asset further must carry the corresponding notice with it.

Removing or altering a notice in this file removes the permission that makes the
corresponding asset redistributable.


Transport Canada — Canadian Civil Aircraft Register (CCARCS)
------------------------------------------------------------
Asset: openairframes_tc_*.csv
Source: https://wwwapps.tc.gc.ca/saf-sec-sur/2/ccarcs-riacc/download/ccarcsdb.zip

Redistribution is permitted under the Government of Canada terms recorded for this
dataset. They require both of the following notices, verbatim, and require that the
two reach the consumer together. The governing instrument is not published on the
CCARCS download page, so no licence name or URL is asserted here.

    Reproduced and distributed with the permission of the Government of Canada.

    This product has been produced by or for the OpenAirframes project and
    includes data provided by the Government of Canada. The incorporation of
    data sourced from the Government of Canada within this product shall not be
    construed as constituting an endorsement by the Government of Canada of our
    product.

Owner mailing addresses published in the CCARCS export (street, city, postal
code, care-of) are dropped during ingestion and are not redistributed.


FAA — Releasable Aircraft Database
-----------------------------------
Source: https://registry.faa.gov/database/ReleasableAircraft.zip

ReleasableAircraft_*.zip is redistributed unmodified. It is a work of the United
States federal government, not subject to copyright protection in the United
States (17 U.S.C. § 105). No notice is required; it is credited for provenance.

openairframes_faa_*.csv is a derived product built by this repository —
normalized, joined, deduplicated, and extended with an identifier this project
defines. Section 105 disclaims copyright in the government's own work and says
nothing about a derivative, so no claim is made here about the CSV's status.


Other redistributed assets
---------------------------
The following assets are republished from third parties whose terms have not
been assessed in this repository. They are listed for provenance only; nothing
here asserts a licence over them.
