Resources sharing between members are a key issue in Collaborative Networked Organizations (CNO). In the software services sector most of companies develops their services by their own and stores them at their local silos without sharing them with other partners. However, the development of services-based applications can be very complex and costly, which is a difficult issue to overcome as most of IT companies are SMEs. In this line this paper proposes a digital catalogue environment to leverage services sharing and larger reuse between CNO members. It is strongly grounded on standard business processes models that would be adopted by all the involved members. The catalogue acts as a collaborative environment that logically embraces all the public services made available by the CNO members, enabling software services developers to compose new services-based applications more agilely. A prototype has been implemented and its results are presented and discussed.
