Exposing Specific Metadata in Digital Images

Abstract: Specific metadata exposure with digital images involves making image metadata values associated with metadata type identification tags accessible via an application programming interface (API). In an example embodiment, a browser exposes an image metadata API that may be called with reference to a particular metadata type identification tag. The browser ascertains a particular image metadata value that is associated with the particular metadata type identification tag from image metadata of a targeted image item. When the particular image metadata value is returned to a caller of the image metadata API, the caller may consume or present the particular image metadata value in any manner.

DEMO: design environment for metadata ontologies

Abstract: Efficient knowledge sharing and reuse—a pre-requisite for the realization of the Semantic Web vision—is currently impeded by the lack of standards for documenting and annotating ontologies with metadata information. We argue that the availability of metadata is a fundamental dimension of ontology reusability. Metadata information provides a basis for ontology developers to evaluate and adapt existing Semantic Web ontologies in new application settings, and fosters the development of support tools such as ontology repositories. However, in order for the metadata information to represent real added value to ontology users, it is equally important to achieve a common agreement on the terms used to describe ontologies, and to provide an appropriate technology infrastructure in form of tools being able to create, manage and distribute this information. In this paper we present DEMO, a framework for the development and deployment of ontology metadata. Besides OMV, the proposed core vocabulary for ontology metadata, the framework comprises an inventory of methods to collaboratively extend OMV in accordance to the requirements of an emerging community of industrial and academia users, and tools for metadata management.

Learning Objects Metadata and Tools in the Area of Operations Research

Abstract: Information technology and the Internet are making inroads into almost all areas of our society. The requirements of students and professionals are fast changing, the information society requires lifelong learning in practically all areas, especially those related to information technologies. The educational sector can profit in particular from the benefits IT adds to the ways of learning. The core techniques exists, still the integration into the curricula and the integration of learning environments and traditional knowledge management systems and libraries cannot keep up with the pace of technology development. This article focuses on the use of so called "learning objects" in the field of Operations Research and Management Science (OR/MS). Learning objects refer to pieces of information of different granularity which can be combined, linked and reused. We will demonstrate some of the concepts mentioned above by the LOM editor of the Technical University of Darmstadt and prototype systems developed in the project OR-World of the University of Paderborn and give an outlook on the future development.

Ubiquitous service finder discovery of services semantically derived from metadata in ubiquitous computing

Abstract: Metadata have been already given to most of the data and objects in the real world, such as books, foods, digital contents like movie, electric devices, and so forth. Further, they can be accumulated electronically by barcodes and RFIDs, which is expected to spread explosively in 2005. On the other hand, web services are getting popular in the internet, and UPnP services and ECHONET are penetrating into the home network. In our project, we propose a new handheld application called Ubiquitous Service Finder, in which user can intuitively browse as icons the metadata around him/her in a cellular phone, then invoke the services semantically related to the metadata by simple drag and drop operation.

Client-side dynamic metadata in web 2.0

Abstract: Web 2.0 brings with it new opportunities for deploying highly interactive webpages. A challenge for Web 2.0 developers is capturing information to document the user experience. Client-side dynamic metadata provides one solution to capturing and logging information on the client-side, while lowering the bandwidth requirements for communication with the server. This paper discusses the architecture of a proof-of-concept system, the Dynamic Metadata Prototype. The architecture is described as an AJAX Design Pattern.
