Proprietary Systems



CONTENTdm remains one of the most popular software platforms for digital collections. Operated and maintained by OCLC, CONTENTdm offers several different pricing options depending on the size of collections and hosting options (both locally and remotely with OCLC servers).

CONTENTdm Server Requirements

  • Microsoft Windows Server® 2008 or 2008 R2; Linux 32-bit or 64-bit (2.6 kernel). Operating system must be 64-bit for Level 3 licenses. Dual-core processor is required but quad-core is recommended. CONTENTdm 6.1 Server has been tested on Red Hat Enterprise Linux/CentOS 5 (32-bit and 64-bit), Ubuntu 10.04 LTS 64-bit, and SUSE Linux Enterprise Server 10. The CONTENTdm 6.1 Server has been successfully installed on other Linux distributions based on the 2.6 kernel, however, not all distributions based on that kernel are supported. Red Hat Enterprise 6 is not yet supported.
  • Dedicated Web server (IIS 7 or 7.5 with Windows® 2008 or 2008 R2, Apache with Linux). Note: CONTENTdm can, and usually does, coexist on systems with other websites and applications. The CONTENTdm 6.1 Server may be installed on the same or on a separate machine from the CONTENTdm 6.1 website. It should have its own Web server (IIS or Apache) instance if it is installed on the same machine.
  • PHP 5.3 with Linux. Note: PHP 5.3 is required for both Server and website if installed on the same Linux machine.
  • 1 GB RAM minimum. 2+ GB RAM recommended. 4 GB RAM required for Level 3 licenses, but 8-12 GB recommended for large installations, especially those with full-text transcriptions.
  • 1 GB of available hard-disk space for installation.
  • Adequate disk space to hold your collection. (For example, if you have JPEGs with an average file size of 100KB, 500 JPEG images would require about 50MB of disk space. Larger image files or audio/video files require additional disk space.)
