Multi-master media metadata synchronization

Abstract: Various embodiments related to the ability to expose content for synchronization and consumption across all endpoint computing devices in a computing system are disclosed. For example, one disclosed embodiment provides a method for communicating between authenticated clients of a cloud-based computing system, including sending a read request for metadata of each of a plurality of endpoint computing devices and content stored on each of the plurality of endpoint computing devices that is aggregated in a data store, receiving the requested metadata. The method further includes performing a content consumption operation that changes a state of the requested metadata. The method further includes sending updated metadata generated based on the content consumption operation to synchronize aggregated metadata in the data store, and deleting local metadata.

Method and system for validating references

Abstract: The present invention relates to enhanced workflow solutions for authors (e.g., researchers, scientists, and scholarly authors) and publishers (e.g., journals and professional and technical societies) in preparing documents in structured format for facilitating efficient and accurate validation of references cited or included in papers and other submissions for publication or for review. An author prepares a document containing a set of cited references using a formatting structure. A system includes a processor to process the document to extract embedded metadata associated with the set of cited references. The processor executes code associated with a reference validation software module and automatically recognizes the formatting structure and the embedded metadata. The processor automatically extracts the embedded metadata and compares the extracted metadata against an authority database to determine the validity of the set of cited references.

Computing device and method for exchanging metadata with peer devices in order to obtain media playback resources from a network service

Abstract: A computing device operates to receive, from at least a first peer device, a set of metadata that includes one or more identifiers to media playback resources. The computing device operates to determine one or more filters for the set of metadata. A metadata from the set of metadata is selected based on the one or more filters. A search request is provided to a network service for a media playback resource based on the selected metadata.

The composite-file file system: decoupling the one-to-one mapping of files and metadata for better performance

Abstract: Traditional file system optimizations typically use a one-to-one mapping of logical files to their physical metadata representations. This mapping results in missed opportunities for a class of optimizations in which such coupling is removed. We have designed, implemented, and evaluated a composite-file file system, which allows many-to-one mappings of files to metadata, and we have explored the design space of different mapping strategies. Under webserver and software development workloads, our empirical evaluation shows up to a 27% performance improvement. This result demonstrates the promise of composite files.

U.s. fgdc content standard for digital geospatial metadata: extensions for remote sensing metadata

Abstract: The U. S. Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata defines common geospatial metadata that allow prospective users to determine the following information about a geophysical data set: its availability, its fitness for an intended use, and the means of accessing and successfully transferring it. Because of its generality, the standard may not meet the metadata needs for specific geospatial domains. The Extensions for Remote Sensing Metadata (hereafter Remote Sensing Extensions) are to provide additional information particularly relevant to remote sensing: the geometry of the measurement process, the properties of the measuring instrument, the processing of raw readings into geospatial information, and the distinction between metadata applicable to an entire collection of data and those applicable only to component parts. For that purpose, the Remote Sensing Extensions establish the names, definitions, and permissible values for new data elements and the compound elements of which they are the components. These new elements are placed within the structure of the FGDC Metadata Content Standard, allowing the combination of the original standard and the new extensions to be treated as a single entity. These extensions are intended to support the collection and processing of geospatial metadata for data derived from remote sensing and to be useable by all levels of government and the private sector. The standard was drafted by a NASA-led team in the FGDC Imagery Subgroup with wide participation from federal agencies, universities, and private industry. Currently the standard is in the FGDC standard approval process. We welcome input and comments from the international remote sensing community for improving the draft standard.
