US Patent 7979448 Mail and calendar tool and method

Access to data in a file created by a mail and calendaring client application is provided to other applications without the need for use of the mail and calendaring client. A request is received from the other application for a document in the file. The document is retrieved in XML form. Sections are expanded by creating URLs and inserting these into the retrieved document. Content of sections is then retrieved in HTML form from the file and inserted into the document at the location of the corresponding URLs. Data for attachments, image tags and other links is obtained and inserted into the document. An object is created containing the entire expanded document and sent to the requesting application.
