This paper addresses a scalability problem in the process of synchronizing the states of multiple client databases which only have deferred access to the server. It turns out that the process of client update file generation is not scalable with the number of clients served. In this paper we concentrate on developing an optimization model to address the scalability problem at the server by aiming for an optimal grouping of data fragments at the server given the "interest sets" of the clients - the set of fragments the client deals with for its"local" processing. The objective is to minimize the total cost of server operation which includes processing updates from all clients and transmission cost of sending the right set of updates to each client based on the client's interest set. An integer programming formulation is developed and solved with an illustrative problem, yielding interesting results.

In this paper we extend the VIVO system with MIR function- ality that allows us to extract the VIVO rule database from a sym- bolic score. As a reference material we use a collection of se- lected Chorale harmonizations by J.S.Bach. Our extended system takes symbolic scores as input and generates a harmonic progres- sion database as output. The VIVO and the new extended sys- tem are realized inside the PWGL environment. Complete work- ing patches are given as examples. As a proof of concept the database-extracted from the repertoire-is then used in the VIVO to re-harmonize a short melody.
