Method for storing/retrieving files of various formats in an object database using a virtual multimedia file system
First Claim
1. In a system server for storing files of various formats in an object database coupled to a network including a multiplicity of clients also coupled to said network, said server having a CPU and at least one storage device coupled thereto, said storage device being disposed for storing objects of said database, a method for storing files of various formats received from one or more of said clients in said database, said method comprising the steps of:
- a. determining the type and content of files received by said system server from said clients coupled to said network, including;
i) extracting a file extension from a name of one of said files;
ii) searching on a file extension class of objects to find an object that matches said file extension extracted in the preceding step;
iii) if a matching file extension is found, traversing a relationship thereof to a MIME Subtype class; and
,iv) choosing a first MIME Subtype object found via said relationship to represent the content of said one of said files;
b. transforming each of said files received by said system server into an object; and
,c. storing each of said transformed objects into a hierarchy in accordance with the type and content thereof; and
,d. returning a code back to that one of said clients which transmitted said file to said server indicating receipt of a file.

Abstract
A method is provided in a server for storing and retrieving files of various formats in an object database coupled to a network including a multiplicity of clients also coupled to the network. The server includes a storage device for storing objects of the database. The method begins by determining the type and content of files received by the server from the clients coupled. Each file received by the server is transformed into an object. The transformed objects are stored in a hierarchy in accordance with the type and content thereof. The retrieving part of the process includes transmitting a "get" request to the server; searching a Virtual File class for an object whose name matches the file name; and examining corresponding properties of the matching object for compatibility with the first parameter. If compatible, a next parameter is examined for corresponding properties for compatibility. When all parameters have been examined, the content is enveloped and returned to the client that originated the "get" request.
