System Requirements: Server

FocusOPEN is based on Windows server technology. The main requirements are:

  • Windows Server 2003/2008/2012
  • IIS 6,7, 7.5 or 8
  • SQL Server 2005/2008/2012

  • Microsoft Internet Explorer (IE) 9-11
  • Mozilla Firefox
  • Apple Safari
  • Goolge Chrome

Other browsers (e.g. Opera) may also work with FocusOPEN, however, these browsers are not formally supported. The FocusOPEN web application can be accessed by all computers that support the above listed browsers, including Windows XP/Vista/7/8 and Apple OS X.

Interoperability With Firewalls And Other Security Devices

FocusOPEN has been tested with a variety of firewalls, proxy servers, packet inspectors and other intrusive security devices and should operate effectively without modification. For maximum stability and security we advise using an SSL encrypted connection and a valid SSL certificate - especially when using proxy connections.

System Architecture

FocusOPEN is delivered using a multi-tier architecture that can be distributed across one or more hosts:

  • Web Application: The core ASP.NET Digital Asset Management system where most of the business logic is contained
  • Database: SQL Server RDBMS
  • Filesystem: Assets are stored in the file system so any accessible file storage device can be used
  • Media Processing: A dedicated Asset Processing Server (APS) is provided as a Windows service


FocusOPEN supports servers farms, clustering, redundancy, and other High Availability (HA) technology. For storing digital assets, FocusOPEN supports multiple storage points and it is possible to store assets in multiple locations simultaneously without consolidating them.

Media Processing & Dependent Components

The APS (Asset Processing Server) is a Windows service and uses WCF (Windows Communication Framework) to exchange messages with the FocusOPEN web application via a designated TCP port. It is a self-contained sub-system and can also be used independently with other WCF compliant applications. FocusOPEN has a number of unmodified free and open source dependencies that are used for media processing and extracting metadata:

Client-Side Components

FocusOPEN uses the following free and open source client-side components:
