Laws and regulation affect software development, as they frequently demand changes in software’ requirements to protect individuals and businesses regarding security, privacy, governance, sustainability and more. Legal requirements can dictate new requirements or constrain existing ones. The problem of software compliance is howto ensure that the software complies with the norms that the legislation imposes. The problem is particularly challenging because it combines difficultsteps: 1)analyze legal documents, 2) extract requirements from those documents, 3) identify conflicting requirements with those already implemented in software and 4) ensure that software remains compliant even with the changes. Compliance is a continuous process: laws, software and the context within which software system operates changes continuously. The works dealing with the compliance problem focus only on one or two subjects: analyze legal documents or extract requirements or identify conflicts or changes. This thesis deals with all the problems at the same time; the idea is to extract requirements from legal text, compare them with the software requirement, resolve the possible conflicts that may arise, continuously leading with the changes on environment, laws and requirements. For this, this work proposes a framework that is composed of a compliance process and continuous monitoring of environmental changes. The framework deals with different types of laws (security, privacy, transparency, health care) that are represented in explicit norms. The compliance process supports the identification, extraction, comparison and conflict resolution to help software compliance, by producing a compliant set of requirements. The compliance process is based on the semantic annotation and goal model. The semantic annotation helps to extract requirements from thelaw, using patterns. The goal model is used to help the comparison between requirement and to represent requirements in a formal and consistent requirement specification. The process is tool supported; some tools were reused (Desiree and NomosT) to further each step. It was necessary to adapt the tools for the context of the compliance process, creating a guideline, patterns, and heuristics. The continuous monitoring is concerned about the changes that affect the software compliance and has 7 the mechanism to ensure that even with those changes the software will regain compliance. The compliance monitor is basedon agents and Non Functional Requirements. The agents are represented using in i*, the idea is to showthe collaboration between the agents to ensure the continuous compliance. The requirement specification of how each agent should behave was also generated using Business Process Modeling Notation and Desiree language. The Non Functional Requirements catalogue is used to help to define operalizations for the software awareness. The framework validation was made in two parts: first, the compliance process and after all the framework proposed. For the compliance process, the effort and correctness were measured comparing the use of the proposed process andan ad-hoc method. For the entire framework, the example of monitoring the changes in the environment when an automated car is crossing the border between Washington and Canada was used. The study shows that context has a strong influence on the software requirements, and nonconformity problems may incur penalties. The contribution of this work is the Eunomia framework that has a process and goal model perspective with emphasis on monitoring that helps to deal with the compliance challenge. The framework equips the requirements engineering team with a systematic method. Eunomia framework is a tool-supported and systematic process which can be reused to reduce the time effort and to improve the quality of the requirement specification that helps to create a compliant software requirement specification that is compliant over the time.
