The Performing Arts Data Service.

The Performing Arts Data Service (PADS), funded by the Joint Information Systems Committee (JISC) and based at the University of Glasgow, aims to support research and teaching in UK Higher Education by collecting and promoting the use of digital data relating to the performing arts: music, film, broadcast arts, theatre and dance. The PADS is one of 5 service providers of the Arts and Humanities Data Service (AHDS) which will provide a single gateway for arts and humanities scholars wishing to search for datasets across various discipline areas. Data is indexed with Dublin Core metadata, will interoperate with other databases within the AHDS and beyond, and will be available via the Web

Serving Massive Time-Based Media (SMaTBaM) - Report on the evaluation process of system needs and demands of serving time -based media in the area of the Performing Arts

The SMaTBaM project (Serving Massive Time-Based Media) aimed to establish a working example of a dataserver for time-based media in the area of the Performing Arts. Building on experience gained in the UMI/NetMuse project, the project will demonstrate the searching and serving of massive realtime data, using a web-based interactive front end. The project is designed directly to enhance the Performing Arts Data Service, PADS , whose remit and funding from the Arts and Humanities Data Service, AHDS, do not extend to conducting research into the development of specialized supporting technology. (PADS is a Glasgow University Arts Planning Unit Project based in the Departments of Music and of Theatre, Film and Television Studies.

The Performing Arts Data Service: Imaginations/Universities Network Pilot Project.

The Performing Arts Data Service (PADS), funded by the Joint Information Systems Committee (JISC) and based at the University of Glasgow, aims to support research and teaching in UK Higher Education by collecting and promoting the use of digital data relating to the performing arts: music, film, broadcast arts, theatre and dance. The PADS is one of 5 service providers of the Arts and Humanities Data Service (AHDS) which will provide a single gateway for arts and humanities scholars wishing to search for datasets across various discipline areas. Data is indexed with Dublin Core metadata, will interoperate with other databases within the AHDS and beyond, and will be available via the Web. Data relating to Performing Arts is by nature diverse: from text based, to visuals/images, to the intrinsically time-based. Any information system for dealing with this range of material must be able to store complex and composite data, cope with a multitude of single documents, and offer intelligent, user-friendly but controlled access over wide area networks. To be of most use to researchers some means of delivery of data is required as well as effective searching. To this end PADS has acquired two Silicon Graphics Origin 200 servers, one of which will act as a media server streaming audio and video over scalable networks; the other will run an object-orientated database (Hyperwave Information Server) which will store both the non-time-based data and the metadata of the material on the media server. A significant issue facing the PADS is that of streaming audio and video to multiple platforms over varying bandwidths. This paper will cover the general information systems requirements for complex multimedia data and the web; will describe in detail the hybrid database and mediaserver system chosen for use at the PADS; and give an overview of current plans for testing video streaming at the PADS in conjunction with the British Film Institute/British Universities Film and Video Council and Joint Information Systems Committee’s “Imagination/Universities Network Pilot”

Processing Structured Hypermedia - A Matter of Style

Vliet, J.C. van [Promotor]Eliens, A. [Copromotor

Music in Time-Based Hypermedia

Hypermedia can be regarded as a merge between multimedia and hypertext. The paper will describe the extension of a hypermedia system with music as a new document type, and the development of a software wrapper to give an existing, music generating program the flexible, interactive and object oriented interface needed by a hypermedia system. Additionally, some consequences of the fundamental difference between static and time-based media will be discussed
