Informations about the package ext-c2pa
ext-c2pa
PHP 8.3+ native C2PA Content Credentials: read/validate manifests and sign
Media Library images (incl. derivatives). PHP namespace Automattic\VIP\C2PA.
The extension half of the wp-c2pa VIP product: the WordPress plugin in
github.com/ericmann/wp-c2pa consumes
this extension (its DESIGN.md, PLAN.md, and CLAUDE.md cover the
product-level picture), and its demo/ harness proves both on a local
vip-go site against a sibling checkout of this repo.
Documentation: c2pa.eamann.com.
Scaffolded from ext-template;
the files listed in its template/managed/ tree are kept in sync with
bin/sync — edit those upstream, not here. Everything else is this
extension's own and has been VIP-ified (namespace, license, copyright).
ext-infer is the worked
reference for house conventions (quality bar, layout, stubs).
License
GPL-2.0-or-later © Automattic, Inc. — consistent with WordPress core. The
"or later" clause is load-bearing: it lets us link the Apache-2.0/MIT
dependencies (c2pa, ext-php-rs) by exercising the GPLv3 option. If
release binaries statically link third-party code, add
THIRD-PARTY-NOTICES.md; the release workflow attaches a transitive
cargo about manifest.
Releases
Pushing a v* tag builds release-mode binaries for the full platform ×
PHP-minor matrix and attaches PIE-convention tarballs to the GitHub
Release (see RELEASE.md for the full procedure). Listing the package on
Packagist/PIE is still deferred.
