A virtual content repository (VCR) is a logical representation of one or more individual content repositories. The VCR uses a common Application Programming Interface (API) and a Service Provider Interface (SPI) to provide a single access point to one or more individual content repositories. The API describes how applications can interface with program logic and functionality provided by the content management system and the SPI describes how a content repository can be integrated into the VCR. A SPI adapter can be interposed between the at least one non-compliant repository in the VCR and the SPI. The SPI adapter can map a request to the non-compliant repository and provide content received from the non-compliant repository to originators of the requests.
