This document discusses customizing the Alfresco content management system to serve as a repository for medical images. The key customizations include: 1) Adding support for common medical image file formats like DICOM, Analyze 7.5, and LSM by writing extra modules for the JHove validation framework. 2) Programming an additional utility to validate DICOM files against Validation Rule Sets which specify required metadata fields. 3) Incorporating the Image Finder extension to enable content-based image retrieval using features like color and texture.
