With the growing role business processes play in today's business life, they are being seen as an asset for the organization. With hundreds of process models developed by different process designers it would be helpful to look up the repository for models that could handle a similar situation before developing new ones. In this paper we introduce a new visual query language for business processes. The language addresses processes definitions. It extends BPMN for its abstract syntax as BPMN is a standard visual notation for modeling business processes. The overall architecture of the system in which the language can fit, in addition to the details of the query processing are also discussed.
