Describing linked datasets with the VoID vocabulary

Abstract: VoID is an RDF Schema vocabulary for expressing metadata about RDF datasets. It is intended as a bridge between the publishers and users of RDF data, with applications ranging from data discovery to cataloging and archiving of datasets. This document is a detailed guide to the VoID vocabulary. It describes how VoID can be used to express general metadata based on Dublin Core, access metadata, structural metadata, and links between datasets. It also provides deployment advice and discusses the discovery of VoID descriptions.

Cloud storage system with distributed metadata

Abstract: A method and system is disclosed for providing a cloud storage system supporting existing APIs and protocols. The method of storing cloud storage system (CSS) object metadata separates object metadata that describes each CSS object as a collection of named chunks with chunk locations specified as a separate part of the metadata. Chunks are identified using globally unique permanent identifiers that are never re-used to identify different chunk payload. While avoiding the bottleneck of a single metadata server, the disclosed system provides ordering guarantees to clients such as guaranteeing access to the most recent version of an object. The disclosed system also provides end-to-end data integrity protection, inline data deduplication, configurable replication, hierarchical storage management and location-aware optimization of chunk storage.

Video management system

Abstract: A system and method for managing video data and metadata associated with the video data is disclosed. In one embodiment, a content management system receives video data and metadata associated with the video data, such as a title, a thumbnail image and a subject matter identifier. Instructions for a media player used to present the video data using a destination site are also generated to simplify distribution of the video data to one or more destination sites. The content management system further enables a user to edit the stored video data to customize placements of advertisements or other data within the video data by identifying one or more cue points in the video data. A data store is coupled to the content management system to store the video data and the metadata associated with the video data.

Compressed journaling in event tracking files for metadata recovery and replication

Abstract: Embodiments are directed towards employing compressed journaling for event tracking files for metadata recovery and replication. Event data and related metadata are received from one or more client devices. When a feature within the received metadata is detected that is previously unwritten to a journal, then the previously unwritten feature is written to the journal. Further, any feature is detected for the received event data that is determined to be different from a feature associated with an immediately preceding event data that is written in the journal, then the detected different feature is identified in the journal. In one embodiment, the identification employs writing to the journal an effective feature record that may employ indices identifying the different feature. The received event data is also written to the journal and may further employ string arguments to minimize recording of redundant information into the journal.

Abstract: Systems and methods for supporting metadata for work items stored in a web-based content management system with collaboration environment are disclosed. Users uploading work items to a folder are not required to provide metadata for the work items. Collaborators of the folder can provide metadata to work items within the folder.

Metadata-Assisted Image Filters

Abstract: This disclosure pertains to devices, methods, systems, and computer readable media for generating and/or interpreting image metadata to determine input parameters for various image processing routines, e.g., filters that distort or enhance an image, in a way that provides an intuitive experience for both the user and the software developer. Such techniques may attach the metadata to image frames and then send the image frames down an image processing pipeline to one or more image processing routines. Image metadata may include face location information, and the image processing routine may include an image filter that processes the image metadata in order to keep the central focus (or foci) of the image filter substantially coincident with one or more of the faces represented in the face location information. The generated and/or interpreted metadata may also be saved to a metadata track for later application to unfiltered image data.

Systems and methods for identifying intersections using content metadata

Abstract: User-submitted content (e.g., stories) may be associated with descriptive metadata (intersection metadata), such as a timeframe, location, tags, and so on. The user-submitted content may be browsed and/or searched using the descriptive metadata. Intersection criteria comprising a prevailing timeframe, a location, and/or other metadata criteria may be used to identify an intersection space comprising one or more stories. The stories may be ordered according to relative importance, which may be determined (at least in part) by comparing story metadata to the intersection criteria.

Gesture-based metadata display

Abstract: In general, embodiments of the present disclosure are directed to techniques for quickly displaying metadata of media objects (e.g., music files) using gestures. In one example a method includes, generating for display a browsing view including browsing content, wherein the browsing content includes one or more media objects; receiving user input including one or more gestures to select at least one media object; determining an input operation that selects a quantity of metadata associated with the selected media object, wherein the metadata includes information that describes the selected media object, and wherein the quantity of the metadata is proportional to a magnitude of the one or more gestures to select the media object; and generating for display in an expanded view, the metadata associated with the at least one selected media object, wherein the expanded view is generated for display without changing the browsing content.

Augmented reality system for position identification

Abstract: A system, method, and computer program product for automatically combining computer-generated imagery with real-world imagery in a portable electronic device by retrieving, manipulating, and sharing relevant stored videos, preferably in real time. A video is captured with a hand-held device and stored. Metadata including the camera's physical location and orientation is appended to a data stream, along with user input. The server analyzes the data stream and further annotates the metadata, producing a searchable library of videos and metadata. Later, when a camera user generates a new data stream, the linked server analyzes it, identifies relevant material from the library, retrieves the material and tagged information, adjusts it for proper orientation, then renders and superimposes it onto the current camera view so the user views an augmented reality.

System and method for resolving a DNS request using metadata

Abstract: A system and method for resolving a DNS request using metadata. An intelligent name server receives a request to resolve a domain name via a network. The intelligent name server acquires at least one metadata element about the source of the request. The domain name request is transformed into a CNAME request that includes the at least one metadata element and the domain name to be resolved. The CNAME request is sent to a metadata aware DNS server for resolution. The metadata aware DNS server maps the domain name to one or more network addresses stored in a look-up table. The included metadata is used to select a “best” host address to include in a response.

Metadata recovery in a disk drive

Abstract: A disk drive subsystem is disclosed that implements a process for metadata recovery. Certain embodiments relate to recovery of metadata containing information indicating the physical locations in the disk drive in which host data is stored. In an embodiment, the metadata to be recovered is disposed in sequence with, or in physical association with host data that it describes. Recovery is accomplished by identifying metadata that is valid, but is absent from one or more translation tables containing translation information. Metadata portion can include one or more identifiers that are sequentially related to identifiers included in one or more other metadata portions. Performance improvements can thereby be attained.

Temporally-correlated activity streams for conferences

Abstract: Techniques are provided for capturing events and activities that occur during a conference, generating metadata related to the events, and correlating the metadata with specific points in time, within the conference, at which the corresponding events occurred. The resulting temporally-correlated event metadata may be stored as part of the conference recording, or separate from the conference recording. Once the temporally-correlated event metadata has been stored for a conference, the conference may be indexed based on the metadata. The index may then be used to not only to locate a conference that satisfies specified search criteria, but to identify the points or snippets, within the conference, that correspond to the search criteria.

Semantic sensor data search in a large-scale federated sensor network

Abstract: Sensor network deployments are a primary source of massive amounts of data about the real world that surrounds us, measuring a wide range of physical properties in real time However, in large-scale deployments it becomes hard to effectively exploit the data captured by the sensors, since there is no precise information about what devices are available and what properties they measure Even when metadata is available, users need to know low-level details such as database schemas or names of properties that are specific to a device or platform Therefore the task of coherently searching, correlating and combining sensor data becomes very challenging We propose an ontology-based approach, that consists in exposing sensor observations in terms of ontologies enriched with semantic metadata, providing information such as: which sensor recorded what, where, when, and in which conditions For this, we allow defining virtual semantic streams, whose ontological terms are related to the underlying sensor data schemas through declarative mappings, and can be queried in terms of a high level sensor network ontology

Secure proxying using network intermediaries

Abstract: Methods and apparatus for secure proxying using network intermediaries. A system may include one or more servers and a network intermediary. The network intermediary may generate security metadata associated with a client request, comprising an identification of a source of the client request, and transmit an encoded version of the security metadata and a backend request to a server. The server may determine whether the security metadata is valid. If the security metadata is validated, the server may perform one or more operations in accordance with the backend request and the security metadata.

On the use of learning object metadata: the GLOBE experience

Abstract: Since IEEE LTSC LOM was published in 2002, it is one of the widest adopted standard for the description of educational resources. The GLOBE (Global Learning Objects Brokered Exchange) alliance enables share and reuse between several Learning Object Repositories worldwide. Being the largest and more diverse collection of Learning Object Metadata, it is an ideal place to perform an analysis of the actual use of the LOM standard in the real world. This paper presents an in-depth analysis of the use and quality of 630.317 metadata instances.

Video search system and method of use

Abstract: A system and method identifies a video file in response to a video based search query. A video imaging device in a mobile device captures a video file, and sends the video file to a search engine. A database associated with the search engine stores pre-indexed metadata of pre-indexed frames of video. A video analyzer separates the received video file into individual frames, analyzes the individual frames received from the mobile device by converting the individual frames into metadata, and compares the metadata to the pre-indexed metadata of the pre-indexed frames stored in the database. The video analyzer then sends a message containing information about the identified pre-existing video back to the mobile device based on the comparison of metadata. The metadata of the file and/or the metadata in the database may include one or more of pixel information, histogram information, image recognition information and audio information for each individual frame.

Methods and systems for processing metadata

Abstract: Systems and methods for processing metadata are described. An application makes available a social networking application with an application programming interface (API) configured to receive social data from a social networking site for a user. The application publisher system receives advertisement metadata from a first system and social data from a social networking site system. Based at least in part on the advertisement metadata and the social data, the application publisher system identifies a suitable advertisement and transmits a request for the identified advertisement to the first system, wherein the social data for the user is not transmitted to the first system, to thereby retain the privacy of the user. The identified advertisement is then electronically provided to the user.

A bottom-up approach to data annotation in neurophysiology

Abstract: Metadata providing information about the stimulus, data acquisition, and experimental conditions are indispensable for the analysis and management of experimental data within a lab. However, only rarely are metadata available in a structured, comprehensive, and machine-readable form. This poses a severe problem for finding and retrieving data, both in the laboratory and on the various emerging public data bases. Here, we propose a simple format, the ”Open metaData Markup Language” (od ML), for collecting and exchanging metadata in an automated, computer-based fashion. In od ML arbitrary metadata informa- tion is stored as extended key-value pairs in a hierarchical structure. Central to od ML is a clear separation of format and content, i.e. neither keys nor values are defined by the format. This makes od ML flexible enough for storing all available metadata instantly with- out the necessity to submit new keys to an ontology or controlled terminology. Common standard keys can be defined in od ML terminologies for guaranteeing interoperability. We started to define such terminologies for neurophysiological data, but aim at a community driven extension and refinement of the proposed definitions. By customized terminologies that map to these standard terminologies, metadata can be named and organized as required or preferred without softening the standard. Together with the respective libraries provided for common programming languages, the od ML format can be integrated into the labora- tory workflow, facilitating automated collection of metadata information where it becomes available. The flexibility of od ML also encourages a community driven collection and definition of terms used for annotating data in the neurosciences.

The Scheme is supported organizationally and will allow for community input on an ongoing basis.

Conflict resolution via metadata examination

Abstract: A provided computing device detects a synchronization conflict between two versions of a file and may examine corresponding metadata fields. The computing device may characterize a nature of a difference between metadata fields as immutable, mergeable, or subsumable. Core metadata fields may be defined such that a nature of a difference, or conflict, is categorized as immutable. Non-core metadata fields may be defined such that a nature of a difference, or conflict, is characterized as either mergeable or subsumable. A conflict between corresponding mergeable non-core metadata fields may be resolved by merging values of the corresponding non-core metadata fields. A conflict between corresponding subsumable non-core metadata fields may be resolved by replacing a value of a non-core metadata field of an older of the two versions of the file with a value of a corresponding non-core metadata field of a younger of the two versions of the file.

The time-localized metadata and a tag mode identifier are retrieved from a database. A tag mode associated with the portion of content is determined based on the time-localized metadata and/or the tag mode identifier. The processor implements a feature based on the time-localized metadata and the tag mode.

Data management server, data management system, data management method, and program

Abstract: There is provided a data management server that is connectable to a plurality of content servers that store content data and metadata that includes content data attribute information and to a client device that acquires the content data based on the metadata. The data management server includes a data collection portion, a data processing portion, and a transmission portion. The data collection portion collects the metadata from each of the plurality of the content servers. The data processing portion hierarchically structures the metadata that the data collection portion collected, based on the attribute information that is included in the metadata. The transmission portion, in response to a request from the client device, transmits to the client device the metadata that was hierarchically structured by the data processing portion.

Methods and systems for caching data shared between organizations in a multi-tenant database system

Abstract: Mechanisms and methods for sharing database content between tenants in a multi-tenant database system are provided. The ability to temporarily store metadata related to the shared data for subsequent use optimizes the data transfer process for multiple data transfers. In an embodiment, the metadata is stored for a pre-determined period of time and fetched again after the period elapses if required. The metadata may be erased from temporary storage if an administrator updates the shared data.

Video analytics system

Abstract: A video analytics system includes a first database for storing searchable time-stamped transactional data indicative of activity within a monitored system, a second database for storing time-stamped video metadata, wherein the time-stamped video metadata comprises searchable attributes associated with a raw video data stream; and a rule-based correlation server for comparing the time-stamped transactional data with the time-stamped video metadata to identify correlation events indicating potential activity of interest. An output subsystem reports the correlation events from the correlation engine. The analytics system is useful for detecting fraud in ATM transactions by comparing the transactional data, for example, the presence of a transaction, with video metadata, for example, indicating whether a transaction occurs when a person is present, for how long the person is there.

Metadata Distribution and Consistency Techniques for Large-Scale Cluster File Systems

Abstract: Most supercomputers nowadays are based on large clusters, which call for sophisticated, scalable, and decentralized metadata processing techniques. From the perspective of maximizing metadata throughput, an ideal metadata distribution policy should automatically balance the namespace locality and even distribution without manual intervention. None of existing metadata distribution schemes is designed to make such a balance. We propose a novel metadata distribution policy, Dynamic Dir-Grain (DDG), which seeks to balance the requirements of keeping namespace locality and even distribution of the load by dynamic partitioning of the namespace into size-adjustable hierarchical units. Extensive simulation and measurement results show that DDG policies with a proper granularity significantly outperform traditional techniques such as the Random policy and the Subtree policy by 40 percent to 62 times. In addition, from the perspective of file system reliability, metadata consistency is an equally important issue. However, it is complicated by dynamic metadata distribution. Metadata consistency of cross-metadata server operations cannot be solved by traditional metadata journaling on each server. While traditional two-phase commit (2PC) algorithm can be used, it is too costly for distributed file systems. We proposed a consistent metadata processing protocol, S2PC-MP, which combines the two-phase commit algorithm with metadata processing to reduce overheads. Our measurement results show that S2PC-MP not only ensures fast recovery, but also greatly reduces fail-free execution overheads.
