# Project Status

The library is at a stage in which the major functionality of the H5P editor and player are working. You can check in the lists below, what is already implemented and what isn't.

## Finished functionality

* [x] store and serve libraries / content types
* [x] store and serve content
  * [x] create, read, update and delete operations on content
  * [x] manage file uploads (= images, video etc.) in temporary files
  * [x] decoupling of storage through interfaces
* [x] provide AJAX endpoints for the editor and player
* [x] backend communication with the H5P Hub
  * [x] register the site
  * [x] send usage statistics
  * [x] get information about content types on the hub
  * [x] download and install new content types / updates of content types on user request
* [x] validation of packages (structural integrity and conformity of content and libraries)
* [x] offers downloads for h5p packages ("exporting" content)
* [x] support for copy & paste in the editor
* [x] support for editor interface languages other than English
* [x] addons (required to display mathematical formulas)
* [x] MongoDB and S3 storage implementation for content and temporary files
* [x] library administration endpoint and React UI component
* [x] check permissions of users (install libraries, download h5p package, embed h5p package, create restricted, update libraries, install recommended, copy h5p?)
* [x] MongoDB and S3 storage implementation for libraries
* [x] Redis cache for caching
* [x] catch and relay xAPI statements
* [x] alter library files, semantics (allows site admins to change libraries without hacking the actual files; very useful) (published soon)
* [x] filter html to prevent cross-site-scripting (XSS) vulnerabilities.
* [x] add csrf tokens to AJAX POST requests
* [x] storing user state in the player (for continuing later where the user left off)

## Unfinished functionality

* [ ] validation of content against full library semantics (currently only text is validated)
* [ ] logging & statistics generation: e.g. use of libraries by author, view of embedded content etc. (see h5p-php-library:h5p-event-base.class.php for a list of events)
* [ ] provide embed route for content \[embed links can be generated but no route yet]
* [ ] bundle and cache assets (aggregates all css and js files into two big files to decrease http requests; done in h5p-php-library:h5p-default-storage.class.php->cacheAssets(...))
* [ ] logging and statistics (there is a debug logger, but not one that allows you to log domain events)
* [ ] mass content updates (possibly funded in the future)
* [ ] option to disable H5P Hub
* [ ] performance optimizations
