User editable metadata for interactive television programs

Abstract: Television programming may be annotated with metadata and the metadata may be shared among subscribers. A set-top box may receive, from a server, metadata relating to a television program, the metadata having been created by users of other set-top boxes and at least some elements of the metadata including information describing portions of the television program to which the metadata is relevant. The set-top box may present the metadata during portions of the television program at which the metadata is relevant.

Ontomet: ontology metadata framework

Abstract: Proper description of data, or metadata, is important to facilitate data sharing among Geospatial Information Communities. To avoid the production of arbitrary metadata annotations, communities agree that creating or adopting a metadata specification is needed. The specification is a document, such as the Geographic Metadata Standard (ISO 19115-2003), which provides a set of rules for the proper use of metadata elements. When a community is adopting a metadata specification it has two main concerns: (1) how can an existing specification be adopted, so that elements can be restricted and domain vocabularies be used? and (2) how can a metadata specification be mapped with another one to achieve interoperability? The two aforementioned concerns are raised due to the fact that: (1) specifications lack domain-specific elements, (2) specifications have limited extensibility, (3) specifications do not always solve semantic heterogeneities and (4) methodologies to create crosswalks among specification have not been formalized. The main goal of this thesis is to present a feasible solution for these problems by providing a flexible environment to allow interoperations of formalized metadata specifications, extensions, crosswalks and domain vocabularies. The main contributions of this thesis are: (1) creation of an abstract model to represent metadata specifications, (2) development of a methodology to extend metadata specifications, called Dynamic Community Profile, and (3) formalization of semantic mappings to perform complex and contextual metadata crosswalks.

XML Metadata Services

Abstract: As the Service Oriented Architecture (SOA) principles have gained importance, an emerging need has appeared for methodologies to locate desired services that provide access to their capability descriptions. These services must typically be assembled into short-term service collections that, together with code execution services, are combined into a meta-application to perform a particular task. To address metadata requirements of these problems, we introduce XML Metadata Services to manage both stateless and stateful (transient) metadata. We leverage the two widely used web service standards: Universal Description, Discovery, and Integration (UDDI) and Web Services Context (WS-Context) in our design. We describe our approach and experiences when designing semantics"" for XML Metadata Services. We report results from a prototype of the system that is applied to mobile environment for optimizing Web Service communications.""

Digital Video Archives: Managing Through Metadata

Abstract: As analog video collections are digitized and new video is created in digital form, computer users will have unprecedented access to video material—getting what they need, when they need it, wherever they happen to be. Such a vision assumes that video can be adequately stored and distributed with appropriate rights management, as well as indexed to facilitate effective information retrieval. The latter point is the focus of this paper: how can metadata be produced and associated with video archives to unlock their contents for end users?
