Abstract

A process for storing a document in a document repository using a content server begins with receiving a client request to store a document. The process then generates a query object to validate the client request. Next, the process generates a document object to initiate a transaction in the document repository using data in the client request. The process also generates a data retrieval object to read data from a client, wherein the data comprises a component of the document. Finally, the process stores the component in the document repository.
