Literature Review Title: Literature Review: Smart Contract Semantics 
Chapter Title:  Business Contract Language 
1. Abstract of Cited Paper (BIB001):  In this paper we present a solution to the problem of designing and implementing a contract monitoring facility as part of a larger cross-organisational contract management architecture. We first identify key technical requirements for such a facility and then present our contract language and architecture that address key aspects of the requirements. The language is based on a precise model for the expression of behaviour and policies in the extended enterprise and it can be used to build models for a particular enterprise contract environment. These models can be executed by a contract engine that supports the contract management life cycle at both the contract establishment and contract execution phases.

Literature Review:
Milosevic et al. BIB001 BIB002 propose the Business Contract Language (BCL). The language consists of roles and policies. Policies encapsulate deontic semantics, as well as associated relative temporal and state based ordering, and absolute temporal constraints.
