It consists of a local network of independently curated exhibits sharing a collaboratively built pool of items, media, and their metadata. See the [user manual](https://omeka.org/s/docs/user-manual) for more information. Installation ------------ [](#installation) ### Requirements [](#requirements) - Linux - [Apache](https://www.apache.org/) (with [AllowOverride](https://httpd.apache.org/docs/2.4/mod/core.html#allowoverride) set to "All" and [mod\_rewrite](http://httpd.apache.org/docs/current/mod/mod_rewrite.html) enabled) - [MySQL](https://www.mysql.com/) 5.7.9+ (or [MariaDB](https://mariadb.org/) 10.2.6+) - [PHP](https://www.php.net/) 8.1+ (latest stable version preferred, with [PDO](http://php.net/manual/en/intro.pdo.php), [pdo\_mysql](http://php.net/manual/en/ref.pdo-mysql.php), and [xml](http://php.net/manual/en/intro.xml.php) extensions installed) ### Generating thumbnails [](#generating-thumbnails) - The default library for generating thumbnails is [ImageMagick](https://imagemagick.org/index.php), at least version 6.7.5. Older versions will not correctly produce thumbnails. For alternative thumbnail options, see the [user manual](https://omeka.org/s/docs/user-manual/configuration/#thumbnails). ### Installing from GitHub [](#installing-from-github) 1. Make sure [Node.js](https://nodejs.org/) and [npm](https://nodejs.org/) are installed 2. Clone this repository in your Apache web directory: - `$ git clone https://github.com/omeka/omeka-s.git` 3. Change into the Omeka S directory: - `$ cd omeka-s` 4. Perform first-time setup: - `$ npm install` - `$ npx gulp init` 5. Open `config/database.ini` and add your MySQL username, password, database name, and host name. The user and database must be created before this step. 6. Make sure the `files/` directory is writable by Apache. 7. In your web browser, navigate to the omeka-s directory, where you can complete installation. ### Installing from released zip file [](#installing-from-released-zip-file) 1. Download the latest release from the [release page](https://github.com/omeka/omeka-s/releases) (download the first asset listed) 2. Open `config/database.ini` and add your MySQL username, password, database name, and host name. The user and database must be created before this step. 3. Make sure the `files/` directory is writable by Apache. 4. In your web browser, navigate to the omeka-s directory, where you can complete installation. You can find Omeka-specific code under `application/`. Updating -------- [](#updating) *Make a backup copy of your entire site and its database!* ### Updating from GitHub [](#updating-from-github) 1. `git pull` as usual. Use the `master` branch for the latest releases. 2. From the Omeka S root directory, run `npx gulp deps` to make sure dependencies are up to date. 3. Compare changes in `/config/local.config.php` and `/config/local.config.php.dist`. Some default configurations might have changed, so you might need to reconcile changes to the distributed configuration with your local configuration (e.g., a path to PHP specific to your server, dev mode settings, etc.) 4. In your web browser, go to your site and run any migrations that are needed. ### Updating from released zip file [](#updating-from-released-zip-file) 1. Download the latest release from the [release page](https://github.com/omeka/omeka-s/releases) 2. Make a copy of your `/config` directory. You will need to restore your `local.config.php` and `database.ini` files from that copy. 3. Make a copy of your `/modules` and `/themes` directories. 4. Make a copy of your `/files` directory. 5. Remove all Omeka S files, and replace them with the files from the updated zip file. 6. Replace your original `/config/local.config.php` file, and the `/modules`, `/themes`, and `/files` directories that you copied. 7. In your web browser, go to your site and run any migrations that are needed. Creating a zipped release ------------------------- [](#creating-a-zipped-release) Run `npx gulp zip` to create a zipped version of Omeka S and store it in `/build`. Use the `--no-dev` flag to omit Composer dev dependencies for a smaller package suitable for end-users. Official releases follow this same process from a new, clean checkout. Libraries --------- [](#libraries) Omeka uses the following libraries, among others: - [Laminas](https://getlaminas.org/) - [Doctrine 2](http://www.doctrine-project.org/) - [EasyRdf](http://www.easyrdf.org/) - [PHPUnit](https://phpunit.de/) - [jQuery](http://jquery.com/) Development Standards --------------------- [](#development-standards) Omeka development adheres to the [Laminas Coding Style Guide](https://docs.laminas.dev/laminas-coding-standard/v2/coding-style-guide/) and uses the [git-flow](http://nvie.com/posts/a-successful-git-branching-model/) branching model and the [Semantic Versioning 2.0.0](https:/semver.org/spec/v2.0.0.html) version scheme. See the [developer documentation](https://omeka.org/s/docs/developer/) for more information.
