An open source content management solution

Alfresco is an open source Enterprice Content Management (ECM) alternative to closed products such as Documentum, IBM DB-2 Content Management, Filenet, Opentext, Interwoven, Vignette and Microsoft's Sharepoint among others.

Alfresco was developed using exclusively Open Source components such as Spring, Hibernate, Lucene. It represents a standards-based alternative to expensive, closed, commercial ECM products. Referenced standards include JSR-168, JSR-170 and JSR-283

Alfresco represents a good example of a business based on open source components and open development culture, Bazaar model, resulting in a content management solution that can be tailored to small and large organizations. Alfresco is licensed under GPL.

The list of customers using it for ECM, collaboration, workflow, document, web, records and image management is impressive for a relatively new product.

It is worth mentioning that Alfresco produced a full functioning, scalable, open ECM alternative to conventional products in less than a year of development effort using the open source components listed below. It represents a very good example of a collaborative, open and successful business developed by reusing existing components.

Alfresco's selection of open source components is a valuable reference, a list of chosen components among a large selection, as well as an excellent example of application development using existing well tested components free of proprietary licenses, royalties, patents and other demons.

Most components with the exception of Spring, OpenOffice, Hybernate and Lucene, are small cleverly crafted software, prepackaged unique functions, chosen by Alfresco to deliver the resulting functional integration in place of custom code.
