TL;DR: The findings of the study suggest that conceptual ambiguities and semantic overlaps inherent among some DC metadata elements hinder semantic interoperability and the development of mediation mechanisms such as concept networks that facilitate the metadata creation and mapping process are critically needed for enhancing metadata quality.
Abstract: This paper is a current assessment of the status of metadata creation and mapping between cataloger-defined field names and Dublin Core (DC) metadata elements across three digital image collections. The metadata elements that evince the most frequently inaccurate, inconsistent and incomplete DC metadata application are identified. As well, the most frequently occurring locally added metadata elements and associated pattern development are examined. For this, a randomly collected sample of 659 metadata item records from three digital image collections is analyzed. Implications and issues drawn from the evaluation of the current status of metadata creation and mapping are also discussed in relation to the issue of semantic interoperability of concept representation across digital image collections. The findings of the study suggest that conceptual ambiguities and semantic overlaps inherent among some DC metadata elements hinder semantic interoperability. The DC metadata scheme needs to be refined in order to disambiguate semantic relations of certain DC metadata elements that present semantic overlaps and conceptual ambiguities between element names and their corresponding definitions. The findings of the study also suggest that the development of mediation mechanisms such as concept networks that facilitate the metadata creation and mapping process are critically needed for enhancing metadata quality.

TL;DR: In this paper, a method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided, where the metadata of the content may be efficiently divided for a purpose of use of a terminal based on general media information or specific media information, and may be transmitted to the terminal.
Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata of the content may be efficiently divided for a purpose of use of a terminal based on general media information or specific media information, and may be transmitted to the terminal. A group may include one or more representations of content. The metadata may include a group element, and the group element may provide a summary of attributes of one or more representations included in the group.

TL;DR: In this article, a hierarchical database, a metadata schema, and a mapping module are provided for passing data between an XML document and a Hierarchical Database (HDB) consisting of a conventional hierarchical database.
Abstract: An apparatus, system, and method are provided for passing data between an XML document and a hierarchical database. The apparatus, system, and method include a hierarchical database, a metadata schema, and a mapping module. The hierarchical database comprises a conventional hierarchical database, such as IMS. The metadata schema is derived from the hierarchical database. The metadata schema includes a first representation representative of the hierarchical structure of the hierarchical database, a second representation representative of the hierarchical structure of XML documents valid for passing into and out of the hierarchical database, one or more database field names, and one or more XML element names that map to the one or more database field names. The mapping module passes data between the XML document and the hierarchical database using the metadata schema.

TL;DR: In this article, a search device receives a search request, extracts at least one of an alias or a metadata name from the search request and converts the alias to metadata name by referring to metadata schema management information for managing in an inclusive manner a namespace alias and metadata name for the retrieval device to identify a metadata schema definition defining the structure of a retrieval-target file that includes metadata.
Abstract: A search device receives a search request, extracts at least one of an alias or a metadata name from the search request, converts the alias to metadata name by referring to metadata schema management information for managing in an inclusive manner a namespace alias and a metadata name for the retrieval device to identify a metadata schema definition defining the structure of a retrieval-target file that includes metadata, and specifies a field name from the metadata name by referring to schema mapping management information for managing the corresponding relationship between a metadata name of metadata schema definition information and a field name of the retrieval index schema definition.

TL;DR: In this article, the authors present a method and system for maintaining the confidentiality of data provided by an organization for storage on a third party database system, where the data can be encrypted on an internal network of the organization and sent to the third-party database system for storage.
Abstract: Methods and systems for maintaining the confidentiality of data provided by an organization for storage on a third party database system are provided. The data can be encrypted on an internal network of the organization and sent to the third party database system for storage. The third party database system can associate metadata with the encrypted data and can store the encrypted data. Accordingly, when a request for the encrypted data is received from a computing device communicating with an internal network of the organization, the encrypted data and associated metadata can be sent to the computing device. A key that is stored on an internal network of the organization can be called through an applet, which utilizes information within the metadata to locate the key on the internal network of the organization.
