TL;DR: The paper presents a multimedia database model accounting for the representation of documents, collections and the associated metadata based on the identification and unification of the main concepts in the archival standards and the audiovisual area.
Abstract: The paper presents a multimedia database model accounting for the representation of documents, collections and the associated metadata. Appropriate structures are provided for descriptive metadata and for metadata resulting from automatic content analysis. The model is based on the identification and unification of the main concepts in the archival standards and the audiovisual area.
The main features of the model, designed to support multimedia database applications, are the integration of descriptive and content analysis metadata, the association of metadata to collections as well as to items, the extensibility with respect to the inclusion of new descriptors and the support to several retrieval modes. The MetaMedia application development platform, based on the model, has been used to support the construction of a historic documentation collection where a common web interface provides collection administrators, metadata creators and visitors a multi-faceted view of the repository.

TL;DR: This approach utilises the incorporation of semantic metadata in addition to resource metadata, resulting in a generally more powerful system than existing global directory services.
Abstract: Metadata systems are concerned with the management of data which describes other data (datasets, catalogues or actual database management systems) and are presently the subject of intensive research. Metadata systems can be used to store richly detailed forms of information, peform seamless wide-randing searches of information distributed across networks, and to integrate information stored in disparate repositories. Here we describe a model design and the methods of implementation derived from the experience of the Leicester University Metadata Project. Our approach utilises the incorporation of semantic metadata in addition to resource metadata, resulting in a generally more powerful system than existing global directory services. A feature of the class of design presented here is flexibility of implementation, with the ability to provide a coherent metadata system functioning above heterogeneous autonomous distributed databases

TL;DR: This work presents the essentials on customisation of the editor by means of two use cases and demonstrates the novel capabilities enabled by RDF-based metadata representation with respect to traditional metadata management in the geospatial domain.
Abstract: Metadata management is an essential enabling factor for geospatial assets because discovery, retrieval, and actual usage of the latter are tightly bound to the quality of these descriptions. Unfortunately, the multi-faceted landscape of metadata formats, requirements, and conventions makes it difficult to identify editing tools that can be easily tailored to the specificities of a given project, workgroup, and Community of Practice. Our solution is a template-driven metadata editing tool that can be customised to any XML-based schema. Its output is constituted by standards-compliant metadata records that also have a semantics-aware counterpart eliciting novel exploitation techniques. Moreover, external data sources can easily be plugged in to provide autocompletion functionalities on the basis of the data structures made available on the Web of Data. Beside presenting the essentials on customisation of the editor by means of two use cases, we extend the methodology to the whole life cycle of geospatial metadata. We demonstrate the novel capabilities enabled by RDF-based metadata representation with respect to traditional metadata management in the geospatial domain.

TL;DR: Simulation results demonstrate that the proposed schema-mapping algorithm, except from requiring less human intervention, can handle real case mapping problems between not only different metadata models but also between models that use different standards for data representation.
Abstract: The interoperability between systems and the reusability of the stored and managed information is a key issue when designing an educational metadata management system. Converting from one data representation to another is time-consuming and labor-intensive, with few tools available to ease the task. In this paper we present a schema-mapping algorithm that is capable of transforming the metadata description of an educational object created using specific metadata specification to a representation of the same object using either another specification (for example from Dublin Core to IEEE LOM and vice versa), or the same specification in another language (for example mapping between different translations of the IEEE LOM standard). We show that using advanced conversion techniques such as the proposed algorithm can result in lower standardization efforts. Simulation results over a wide range of learning objects demonstrate that the proposed algorithm except from requiring less human intervention, can handle real case mapping problems between not only different metadata models but also between models that use different standards for data representation.
