Its 2.x line was later based on the Adobe XMP SDK and kept a BSD-style license to preserve compatibility with upstream XMP SDK code sharing. The project reshaped the SDK for open-source desktop packaging: a stable C API and ABI, automake-based builds, broader Unix and architecture support, WebP support, tests, and no contributor license agreement. The exempi command-line tool appeared as a work in progress beginning with the 2.2.0 series. ### Adoption history Exempi is mostly adopted as infrastructure. Desktop, image, and metadata tools use it when they need XMP parsing without embedding Adobe's C++ SDK directly, and the project points users to distribution packages for binary installation. ### How it is used The library is the main surface: applications use its C API to read and write XMP metadata. The bundled exempi executable gives package users a command-line way to inspect or manipulate XMP packets. ### Why package nerds care Exempi matters to package maintainers because it turns a vendor-origin metadata SDK into a conventional Unix library with stable ABI expectations, distro-friendly licensing, and language bindings such as the separate Rust crates. ### Timeline - 0.5.x: Exempi existed as an implementation before the XMP SDK was available. - 2.2.0: The exempi command-line tool began appearing in the 2.x series. - 2.4.0: Rust crate use became documented for Exempi 2.4.0 and later. - 2.6.6: The project page lists 2.6.6 as the current 2.x release. ### Related projects - Exempi is related to Adobe XMP SDK, libopenraw, XMP metadata tooling, and the exempi2 Rust binding ecosystem. ### Sources -
