Patent Issued for Metadata That Allows Refiltering and Data Reclassification without Accessing the Data

July 8, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Milligan, Charles A. (Golden, CO); O'Nions, Gerald (Toulouse, FR), filed on May 31, 2006, was published online on June 24, 2014.

The assignee for this patent, patent number 8762418, is Oracle America, Inc. (Redwood City, CA).

Reporters obtained the following quote from the background information supplied by the inventors: "The present invention relates to methods and object storage systems that allow re-filtering and re-classification of one or more objects via metadata without directly accessing the object associated with the metadata.

"Currently, there is much interest in storage systems that can be used to store a variety of objects. Such systems may, for example, be used to store digital data, analog data, objects de art, manufactured components, paper documents, other forms of storage media such as magnetic tape, optical disk, holographic storage, and the like. Therefore, in the context of data storage systems, Information Lifecycle Management ('ILM') approaches, including data archive techniques, resource management techniques, and data warehousing, typically use a data classification mechanism with data entities such as data objects in object based storage, files in file systems, data sets in mainframe systems, or table or matrix subsets of a database.

"In such storage systems, the common management approach is to use a classification system, i.e., when data objects are first received in the storage system, they are individually added to some classification grouping. When one of the other stored objects delineated above (e.g., a painting--object de art) are added to a storage system intended to manage such objects, it is also generally placed in the system according to some consistent classification system. Common archive and compliance data storage solutions invoke a data management approach classifying data objects individually into specific classifications.

"The current art is based on a technique that uses a filter to process the data and other system metadata about the object in order to identify the preferred specific classification for a particular object. The filtering process must resolve classification ambiguity problems where there are many almost equivalent potential class assignments for any particular data object. However, a minor change in the focus of the business could drive a significant change in the filtering process (and thus results) which in turn could actually require every object in the system to be read again and reclassified for correct system operation. Today this would be an overwhelming performance problem. Current systems avoid this problem rather than solving it.

"Accordingly, there exists a need in the prior art for improved methods and systems for filtering and reclassifying stored data."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "The present invention solves one or more problems of the prior art by providing in one embodiment a method for reclassifying stored objects without the need to re-access and re-evaluate such objects. The method of this embodiment comprises receiving an object to be stored in a storage system and then associating metadata with the object. The metadata can be received from outside the storage system with or independent of the received object and/or it can be generated within the storage system. The metadata is stored in a data storage system part of or associated with the object storage system. Advantageously, the metadata is used to create a plurality of classification recommendations associated with each object."
