Processing of metadata content and media content received by a media distribution system

Abstract: The disclosed embodiments relate generally to the submission of metadata content and media content to a media distribution system. The media content can include, for example, audio, video, image, or podcast data. In accordance with one embodiment, a client submitting metadata content can validate the metadata content prior to submission of the metadata content and/or associated media content. A media distribution system receiving metadata content can also validate the metadata content.

Metadata Statistics for a Large Web Corpus.

Abstract: We provide an analysis of the adoption of metadata standards on the Web based a large crawl of the Web. In particular, we look at what forms of syntax and vocabularies publishers are using to mark up data inside HTML pages. We also describe the process that we have followed and the difficulties involved in web data extraction.

Cache metadata identifiers for isolation and sharing

Abstract: Various technologies and techniques are disclosed for providing software accessible metadata on a cache of a central processing unit. A multiprocessor has at least one central processing unit. The central processing unit has a cache with cache lines that are augmented by cache metadata. The cache metadata includes software-controlled metadata identifiers that allow multiple logical processors to share the cache metadata. The metadata identifiers and cache metadata can then be used to accelerate various operations. For example, parallel computations can be accelerated using cache metadata and metadata identifiers. As another example, nested computations can be accelerated using metadata identifiers and cache metadata. As yet another example, transactional memory applications that include parallelism within transactions or that include nested transactions can be also accelerated using cache metadata and metadata identifiers.

System and method for recovery units in databases

Abstract: The creation of multiple recoverable units within a database allows a database partition to be reconstructed during maintenance and disaster recovery operations A method of creating a recovery unit includes partitioning a database into at least two recovery units A primary catalog of metadata relating to the logical elements of a database such as tables, indexes, and file groups is created A secondary catalog of metadata relating to the physical elements of a database such as pages, files, B-Trees, and log streams is created for each recovery unit The primary and secondary metadata catalogs are linked such that only one log stream is associated with any one recovery unit A single recovery unit may then be exercised to perform recovery or maintenance operations while the remaining recovery units of the database remain online

Selecting data for synchronization

Abstract: A method for selecting a data set to be synchronized from databases of a data system, in which system metadata illustrating the relationships between data units of the data system are stored for the selection of the data set to be synchronized. The metadata comprises at least information on the relevance between the data units. When a first data set is to be synchronized, metadata associated with at least one initial data unit of the first data set is retrieved. Next, a second data set, which according to at least one metadata element comprises a data unit of maximum relevance to the initial data unit, is selected for synchronization.
