Briefly, the present invention relates to an information dispersal sytem in which original data to be stored is separated into a number of data “slices” in such a manner that the data in each subset is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other data subsets. These data subsets are stored on separate storage devices as a way of increasing privacy and security. In accordance with an important aspect of the invention, a metadata management system stores and indexes user files across all of the storage nodes. A number of applications run on the servers supporting these storage nodes and are responsible for controlling the metadata. Metadata is the information about the data, the data slices or data subsets and the way in which these data subsets are dispersed among different storage nodes running over the network. As used herein, metadata includes data source names, their size, last modification date, authentication information etc. This information is required to keep track of dispersed data subsets among all the nodes in the system. Every time new data subsets are stored and old ones are removed from the storage nodes, the metadata is updated. In accordance with an important aspect of the invention, the metadata management system stores metadata for dispersed data where: The dispersed data is in several pieces. The metadata is in a separate dataspace from the dispersed data. Accordingly, the metadata management system is able to manage the metadata in a manner that is computationally efficient relative to known systems in order to enable broad use of the invention using the types of computers generally used by businesses, consumers and other organizations currently.

An archive cluster application runs in a distributed manner across a redundant array of independent nodes. Each node preferably runs a complete archive cluster application instance. A given nodes provides a data repository, which stores up to a large amount (e.g., a terabyte) of data, while also acting as a portal that enables access to archive files. Each symmetric node has a set of software processes, e.g., a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests to the node for data (i.e., file data), the storage manager manages data read / write functions from a disk associated with the node, and the metadata manager facilitates metadata transactions and recovery across the distributed database. The policy manager implements one or more policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage. Preferably, the application permanently associates metadata and policies with the raw archived data, which together comprise an archive object. Object policies govern the object's behavior in the archive. As a result, the archive manages itself independently of client applications, acting automatically to ensure that all object policies are valid.

The present invention provides methods and systems to improve network searching for watermarked content. In some implementations we employ keyword searching to narrow the universe of possible URL candidates. A resulting URL list is searched for digital watermarking. A system is provided to allow customer input. For example, a customer enters keywords or network locations. The keywords or network locations are provided to a watermark-enabled web browser which accesses locations associated with the keywords or network locations. Some implementations of the present invention employ a plurality of distributed watermark-enabled web browsers. Other aspects of the invention provide methods and system to facilitate desktop searching and automated metadata gathering and generating. In one implementation a digital watermark is used to determine whether metadata associated with an image or audio file is current or fresh. The metadata is updated when it is out of date. Watermarks can also be used to link to or facilitate so-called on-line “blogs” (or online conversations).

An archival storage cluster of preferably symmetric nodes includes a metadata management system that organizes and provides access to given metadata, preferably in the form of metadata objects. Each metadata object may have a unique name, and metadata objects are organized into regions. Preferably, a region is selected by hashing one or more object attributes (e.g., the object's name) and extracting a given number of bits of the resulting hash value. The number of bits may be controlled by a configuration parameter. Each region is stored redundantly. A region comprises a set of region copies. In particular, there is one authoritative copy of the region, and zero or more backup copies. The number of backup copies may be controlled by a configuration parameter. Region copies are distributed across the nodes of the cluster so as to balance the number of authoritative region copies per node, as well as the number of total region copies per node. Backup region copies are maintained synchronized to their associated authoritative region copy.

The present invention is a method and system for associating metadata with user data in a storage array in a manner that provides independence between metadata management and a storage controller's cache block size. Metadata may be associated with user data according to multiple fashions in order to provide a desired performance benefit. In one example, the metadata may be associated according to a segment basis to maximize random I / O performance and may be associated according to a stripe basis to maximize sequential I / O performance.

Systems and methods for synchronizing data stores. A framework including a sync runtime enables consistent and manageable synchronization between a data store and multiple, diverse back end data stores. The sync runtime provides services such as change enumeration, conflict detection, metadata management, item ID matching, sync interruptability, and the like that are accessible to configurable adapters over an application programming interface. Each synchronizing data store can uses a sync controller to initialize an adapter that can access the services provided by the sync runtime. The sync controller can use a profile to configure each adapter. The profile can identify conflict resolution policies, synchronization filters, source and destination folders, sync direction, and the like.

An edge server in a distributed processing environment includes at least one process that manages incoming client requests and selectively forwards given service requests to other servers in the distributed network. According to the invention, the edge server includes storage (e.g., disk and / or memory) in which at least one forwarding queue is established. The server includes code for aggregating service requests in the forwarding queue and then selectively releasing the service requests, or some of them, to another server. The forward request queuing mechanism preferably is managed by metadata, which, for example, controls how many service requests may be placed in the queue, how long a given service request may remain in the queue, what action to take in response to a client request if the forwarding queue's capacity is reached, and the like. In one embodiment, the server generates an estimate of a current load on an origin server (to which it is sending forwarding requests) and instantiates the forward request queuing when that current load is reached.

A system, method and computer program product for implementing a distributed file system architecture requiring no direct access to user data from a metadata manager in a data storage network. Metadata operations requiring user volume access are performed via a proxy on a storage manager server that is a distributed file system client. Management of metadata can be isolated from user data because the metadata manager requires no capability to see the storage for user volumes. This allows for a distributed file management system to support heterogeneous environments without requiring any single point in the system to see all the storage.

Techniques for managing a playlist in a multimedia system are disclosed. According to one aspect of the techniques, the playlist is structured to be able to include as many items as desired. To facilitate the manageability of such playlist, the playlist is built with a plurality of items. Each of the items is associated with metadata that includes information related to, for example, artist, album, genre, composer, and track number. The metadata for each item may be parsed, updated or logically operated upon to facilitate the management of the playlist. In another embodiment, each of the items is either a single item or a group item. A single item contains metadata of a corresponding source. A group item contains metadata of accessing other constituent items, which again may be single items or group items. As a result, the playlist can accommodate as many items as desired in a limited memory space without compromising the manageability of the playlist. Each of the items can be removed from, added to, or moved around in the playlist without concerning that an item may further include many items therein.

A processing system comprises one or more processor devices and other system components coupled to a stacked memory device having a set of stacked memory layers and a set of one or more logic layers. The set of logic layers implements a metadata manager that offloads metadata management from the other system components. The set of logic layers also includes a memory interface coupled to memory cell circuitry implemented in the set of stacked memory layers and coupleable to the devices external to the stacked memory device. The memory interface operates to perform memory accesses for the external devices and for the metadata manager. By virtue of the metadata manager's tight integration with the stacked memory layers, the metadata manager may perform certain memory-intensive metadata management operations more efficiently than could be performed by the external devices.

A method for representing RDF data in a database provides a new RDF data type built on top of a network data model (NDM), where a network or graph captures relationships between objects using connectivity. This exposes the NDM functionality to RDF data, allowing RDF data to be managed as objects and analyzed as networks. In this network, the subject and objects of triples are mapped to nodes, and the predicates are mapped to links that have subject start-nodes and object end-nodes. A link, therefore, represents a complete RDF triple. The nodes are stored only once, regardless of the number of times they participate in triples. But a new link is created whenever a new triple is inserted. A streamlined approach to representing reified RDF data is also provided for faster retrievals. An RDF object type and reification in the database thus provide a basic infrastructure for effective metadata management.

Peer-to-peer file sharing and uploading of content to content server systems is increasing in popularity on the Internet. Content signals can be edited and combined with other content programming, and or altered in ways that make it difficult to identify using conventional techniques. Content identification based on content fingerprints is used to retrieve related metadata, which in turn, is used to manage use of the content signal in content distribution systems. The content signal is uploaded to a computer within a network of computers in the content distribution system. A content fingerprint of the content signal is computed and sent to a database to look up related metadata. The metadata is received and used to manage use of the content signal in the content distribution system based on the metadata. This can include blocking uploading or rendering of audio or video, controlling streaming of audio or video, linking to a licensing server, which provides usage control rules, etc.
