Motivation ---------- [](#motivation) Wikimedia Commons contains images and other freely usable media files. Some files can be used without any conditions (public domain), others are licensed under an open content license. Depending on the particular license one has to give proper credit to the original author and/or name the specific license. Wikimedia Commons includes guidelines [how to give proper credit](https://commons.wikimedia.org/wiki/Commons:Credit_line) but there is no easy way to look up attribution requirements for a given image in machine-readable format. There is a method to retrieve some license information via Wikimedia Commons API, but the API is difficult to find and query, its return format is too verbose, and the response is not usable without further processing. For instance licenses are spelled in several different ways ("CC-BY-SA-3.0", "CC BY-SA 3.0"...) and field values may contain HTML tags. Requirements ------------ [](#requirements) Requires PHP 5.6 or above and `allow_url_fopen` enabled. Installation ------------ [](#installation) Use composer: ``` $ composer require gbv/image-attribution ``` or just copy files `src/image-attribution.php` and `src/identify-open-content-license.php` by hand. Usage ----- [](#usage) Use autoload: ``` require 'vendor/autoload.php'; ``` or include the library file the old way: ``` require_once 'src/image-attribution.php'; ``` Then make use of the function `commons_image_attribution`: ``` $attribution = commons_image_attribution("Loewe_frontal.JPG"); ``` The image can be passed as file name, full image URL or URL of the image page. The value `null` will return a random image. If the image is found with a license, an array is returned with the following fields: fieldcontent`src`URL of the image file`url`URL of the image description page`license`URI of the license or `null` if unknown`license_name`short name of the license or `null` if unknown`attribution`boolean value whether attribution is required, or `null` if unknown`sharealike`boolean value whether share-alike is required, or `null` if unknown`creator`creator of the image, or `null` if unknown`credit`credit string to give attribution with creator and license`description`image description as plain string, or `null` if unknown`date`date of the image as plain string, or `null` if unknown`restrictions`additional restrictions, such as "trademarked", or `null``name`(file)name of the image`mime`image mime type`size`image size in bytes`width`image width in pixels`height`image height in pixelsExamples -------- [](#examples) Directory `example` includes a web service (`index.php`) to query image attribution information as JSON. The service is deployed at but may be slow or down from time to time. Please install at your own server if you need to use it frequently! To give an example: - Directory `bin` contains a command line script to get image attribution: ``` ./bin/image-attribution Wikimedia-logo.svg ``` ### Health Score 24 — LowBetter than 31% of packages Maintenance7 Infrequent updates — may be unmaintained Popularity17 Limited adoption so far Community11 Small or concentrated contributor base Maturity50 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
