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.

Metadata processing method, metadata storing method, metadata adding apparatus, control program and recording medium, and contents displaying apparatus and contents imaging apparatus

Abstract: The present invention enables to select necessary metadata from presumed metadata candidates that are more likely to be added and to easily select metadata desired by a user, thereby reducing working load on a user largely, and facilitating the operation of adding shooting scene information even to a large amount of shot data recorded in a large-capacity recording medium. In order to achieve these objects, the present invention comprises: a processing process of detecting metadata associated with second contents data from the second contents data which is in a same category as first contents data; and a processing process of selectably outputting candidates of non-time information metadata to be stored, associated with the first contents data, in storing means, based on time information metadata and non-time information metadata associated with the second contents data and time information metadata associated with the first contents data which is to be added metadata next.

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.

Method and apparatus for building metadata driven software development kit

Abstract: A metadata driven software development system provides various functionalities related to an entity of an application in the metadata format. Specifically, the system provides a set of base classes related to the entity and a set of methods and application programming interfaces for various operations to be performed on the entities in the metadata format. Defining such functionalities in the metadata format allows the system to dynamically generate XML messages matching any customized schema for that entity. Because such functionality is metadata driven, this system can be used with customized versions of the application without requiring any additional code or recompilation.

File system architecture requiring no direct access to user data from a metadata manager

Abstract: 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.
