Method and system for managing metadata for a virtualization environment

Abstract: Disclosed is an improved approach for managing updates to metadata for a virtualization environment. According to some embodiments, a compare and swap approach is taken to manage updates and to handle possible inconsistencies.

Metadata Templates for Electronic Healthcare Documents

Abstract: A computing device according to one example embodiment includes one or more processing devices configured to display an interface to a user for entry of metadata values and identification of corresponding metadata fields, to create a metadata template from entered metadata values and identified corresponding metadata fields, and to store the created metadata template as default metadata for a non-DICOM electronic healthcare document to be submitted to an electronic repository.

Abstract: Provided are a method and apparatus for processing multimedia content and metadata in order to efficiently manage the metadata. The method includes forming an audio/video content file structure comprising a plurality of fundamental units for storing multimedia data and metadata, and adding metadata update related information to each of the fundamental units.

XML based Metadata Repository for Information Systems

Abstract: Today's information systems include many components and computational processes such as data warehouses, data marts, ETL processes, data analysis tools, etc. An appropriate integration of these components requires the extensive use of metadata. However the representation, consolidation, management, and access to this metadata information can cause a major overhead in the system. This paper presents an XML based metadata repository that consists of a centralized repository built upon standard XML technologies such as XML Schema, XSL, XQuery and XLink, coupled with an appropriate storage that proved to be a flexible, and yet inexpensive, metadata solution. Moreover it provides the means for the metamodel extensibility and easy integration into any information system. The feasibility of this solution is documented by the description and discussion of a prototype implementation currently deployed and running in operational state as part of a complex information system

A study on metadata elements for web‐based reference resources system developed through usability testing

Abstract: Purpose – To propose correct metadata elements, it was deemed necessary to close the gap between the perception of metadata creators and data creators through a user behavior analysis. This study aims to improve metadata elements of web‐based reference resources.Design/methodology/approach – The study employed three types of surveys: behavior analysis of metadata creators, perception analysis of users, and system satisfaction. For analysis of metadata creators, the study examined data fields where metadata were recorded among metadata elements of reference resources. For user awareness analysis, respondents were asked to answer the necessity of 17 elements after they actually had entered data and to recommend other necessary elements. Finally, system satisfaction survey was followed.Findings – As a result, first, it was found that the respondents recognized five elements: contributor, source, data, format, and relation as necessary input elements, which in practice had not been well recorded in real opera...
