CJW Mediaconnector Extension

CJW Mediaconnector is an eZ Publish extension for file upload and file management on external servers. You can use simple network file systems like FTP or WebDAV or external cloud storage services like Youtube or Slideshare.

The CJW Mediaconnector extension defines a new "cjwmediaconnector" datatype.

It is based on and forked from the ezmedia datatype and has a lot of additional hooks. These are for triggering actions like "save" of "delete" of files on external storages. The database table for persistant objects is modified to meet the special needs for file meta data.

You can extend the extension for new demands and services with the easy plug-in architecture. Specific services requirements are implemented in the corresponding plug-in.

Currently there are three services implemented:

  • FTP
  • WebDAV
  • Youtube

These are working reference implementations with can be used for new plug-in developments and which can be improved, too. Writing new plug-ins is very easy, just take for example the FTP plug-in as a starting point. The complexity comes only from the service which you want to implement.
