A Methodology for Quality Assessment in Collaborative Score Libraries.

We examine quality issues raised by the development of XML-based Digital Score Libraries. Based on the authorsu0027 practical experience, the paper exposes the quality shortcomings inherent to the complexity of music encoding, and thelack of support from state-of-the-art formats. We also identify the various facets of the ``qualityu0027u0027 concept with respect to usages and motivations. We finally propose a general methodology to introduce quality management as a first-level concern in the management of score collections, and an initial taxonomy of quality problems based on real use cases.
