Preservation of interactive multimedia performances

Preservation of Interactive Multimedia Performances (IMPs) is becoming important, as they are getting more and more popular in the performing arts communities. Preservation requires keeping not only all the necessary components for the production of a performance but also the knowledge about these components so that the original production process can be repeated at any given time. Ontologies provide the means for semantic processing, cataloguing and querying on preserved digital objects. In this paper, a framework for digital preservation of IMPs is introduced. The framework is based on the use of ontologies for describing the complex relationships among different components of a performance to support its preservation.

Metadata Editing and Mapping within the AXMEDIS Framework

Metadata is increasingly used in the digital industry for content description. In line with this emerging trend, the AXMEDIS framework has employed several kinds of metadata for describing digital items embedded in AXMEDIS Objects. This paper introduces the metadata utilised inside AXMEDIS Objects and presents the AXMEDIS Metadata Editor and Mapper which provide graphical user interface and tools for metadata manipulation to accelerate the production and automated transcoding of metadata.

Ontology for Preservation of Interactive Multimedia Performances

Preservation of interactive multimedia performances is becoming important as they are getting more and more popular in performing arts communities. A proper preservation does not only require keeping all the necessary components available at the time of reconstruction but also the knowledge about these components are assembled together for in performance. In digital preservation, metadata has been seen as a mean of enabling semantic processing, cataloguing and querying on preserved digital objects. However, as a record based approach, metadata is weak at describing interrelationships between digital objects in digital archives, which is one of the key requirements for preservation of interactive multimedia performances. In this paper, a domain ontology for describing the complex relationships amongst different components of a performance to support its preservation process is introduced.

Practicing Ontology Modelling for Preservation of Interactive Multimedia Performances

The need to address the fragility of the digital information collected in artistic activities is urgently emerging and increasing. This need is particularly heightened by new multimedia technologies that support the artistic community with many different forms of digital means. The present work concerns an ontology layering architecture for organizing and maintaining a semantic knowledge base for digital preservation of interactive multimedia performances. In addition, the use of certain ISO standardized ontologies is demonstrated in modelling the domain of interactive multimedia performances.

Ontology-based temporal modelling of provenance information

With the advancements in human-computer interaction and related technologies, such as motion capture, sensor interface and analysis, interactive multimedia performances are rapidly gaining ground within the performing arts communities. This has brought forward the need for digital preservation of these performances, so that they can be reconstructed with accuracy for re-performance or analysis in the future. This paper presents an ontology-based temporal model for the representation of provenance information. The proposed ontology model addresses the temporal aspects of the components of a performance and targets their evolution over time.

AXMEDIS Programme and Publication Tools for Cross Media Content Multichannel Distribution

AXMEDIS has provided an innovative framework with a wide range of tools for cross-media content processing, production and multi-channel distribution. This paper focuses on one of the key sections of the framework, the Programme and Publication (P&P) tools, which include the P&P Engine and P&P Editor, providing a focal point for multi-channel distribution. The P&P Editor is an integrated GUI environment where users can search for contents and specify their distribution details (e.g. transmission channel, date and time), the so-called P&P Programme. Once a P&P Programme is created and activated, the contents can be processed and delivered automatically, as defined by the P&P programme. Additionally, end users/consumers may also query contents on-demand via the P&P Engine. This paper provides an overall view of the P&P tools and presents two demonstrators to illustrate the P&P toolspsila capabilities.

AXMEDIS Programme and Publication Tools: A Case Study with Satellite Distribution

The AXMEDIS project is exploring an integrated framework on cross-media content processing and production for multi-channel distribution. This paper presents one of the key sections of the framework with particular focus on the programme and publication (P&P) interface for defining programme and distribution of contents. The P&P tools provide an integrated environment with GUI where users can search for contents, create/edit programmes, and specify the transmission channel. Once a P&P programme is created and activated, the contents can be processed and delivered in an automatic manner as defined by the P&P programme. To demonstrate the functionalities of the AXMEDIS P&P tools, this paper presents a case study which utilises the P&P tools for the distribution of the AXMEDIS contents via satellite data broadcast provided by the EUTELSATs OPENSKY platform.

An Ontology Based Framework for the Preservation of Interactive Multimedia Performances

Interactive multimedia and human-computer interaction technologies are effecting and contributing towards a wide range of developments in many different subject areas including contemporary performing arts. These technologies have facilitated the developments and advancements of augmented and virtual instruments for interactive music performance, interactive installation, many aspects of technology-enhanced learning (TEL) and others. These systems typically involve several different digital objects including software as well as data that are necessary for the performance and/or data captured/generated during the performance that may be invaluable to understand the performance. Consequently, the preservation of interactive multimedia systems and performances is an important step to ensure possible future re-performances as well as preserving the artistic style and heritage of the art form. This paper presents the CASPAR framework (developed within the CASPAR EC IST project) for the preservation of Interactive Multimedia Performances (IMP) and introduces an IMP archival system that has been developed based on the CASPAR framework and components. This paper also discusses the main functionalities and validation of the IMP archival system developed.

Bringing music industry into the interactive multimedia age

The MUSICNETWORK has been funded by the European Commission to help bringing music into the interactive multimedia era. It represents a Centre/Network of Excellence where music content providers, cultural institutions, industry, and research institutions work together drawing on their collective assets and mutual interests, to exploit the potential of multimedia music content with new technologies, tools, products, formats and models. There is currently a large gap between the technology and content providers. Many products in the market fail to optimally exploit the potential of new multimedia technologies. MUSICNETWORK helps research solutions to reach the market by seeking agreements between different actors and formats, by bringing together research institutions, industries, small and medium enterprises (SMEs), and experts to build the required momentum to study and define multimedia music modeling and coding for the new age. MUSICNETWORK activities, actions and services are provided through the project Web site which can be found online at www.interactivemusicnetwork.org.
