Meta-model Pruning
Large and complex meta-models such as those of Uml and its profiles are growing due to modelling and inter-operability needs of numerous\ud
stakeholders. The complexity of such meta-models has led to coining\ud
of the term meta-muddle. Individual users often exercise only a small\ud
view of a meta-muddle for tasks ranging from model creation to construction\ud
of model transformations. What is the effective meta-model that represents\ud
this view? We present a flexible meta-model pruning algorithm and\ud
tool to extract effective meta-models from a meta-muddle. We use\ud
the notion of model typing for meta-models to verify that the algorithm\ud
generates a super-type of the large meta-model representing the meta-muddle.\ud
This implies that all programs written using the effective meta-model\ud
will work for the meta-muddle hence preserving backward compatibility.\ud
All instances of the effective meta-model are also instances of the\ud
meta-muddle. We illustrate how pruning the original Uml metamodel\ud
produces different effective meta-models
Business process and practice alignment meta-model
Business Process Modelling (BPM) is one of the most important phases of information system design. Business Process meta-models allow capturing informational and behavioural aspects of business processes. Unfortunately, standard business process meta-modelling approaches, such as the Business Process Model and Notation (BPMN) Meta-model, Quality-Oriented Business Process Meta-Model (QOBPM) and Transactional Meta-Model for Business Process (TMBP) focus just on process description, providing different business process models. According to these meta-modelling approaches, it is not possible to compare and identify related daily practices in order to improve business process models. This lack of information recognizes that further research in Business Process (BP) meta-model is needed to reflect the evolution/change on software processes. Considering this limitation in BP meta-modelling, this paper presents a comparative study of the most recognized business process meta-models approaches and introduces a new BP meta-model designed by Business Process and Practice Alignment Meta-model (BPPAMeta-model). Our intention is to present observed problems in existing approaches and propose a business process meta-model that addresses features related to the alignment between daily work practices and business process descriptions.

Applying the business process and practice alignment meta-model: Daily practices and process modelling
Background: Business Process Modelling (BPM) is one of the most important phases of information system design. Business Process (BP) meta-models allow capturing informational and behavioural aspects of business processes. Unfortunately, standard BP meta-modelling approaches focus just on process description, providing different BP models. It is not possible to compare and identify related daily practices in order to improve BP models. This lack of information implies that further research in BP meta-models is needed to reflect the evolution/change in BP. Considering this limitation, this paper introduces a new BP meta-model designed by Business Process and Practice Alignment Meta-model (BPPAMeta-model). Our intention is to present a meta-model that addresses features related to the alignment between daily work practices and BP descriptions. Objectives: This paper intends to present a meta-model which is going to integrate daily work information into coherent and sound process definitions. Methods/Approach: The methodology employed in the research follows a design-science approach. Results: The results of the case study are related to the application of the proposed meta-model to align the specification of a BP model with work practices models. Conclusions: This meta-model can be used within the BPPAM methodology to specify or improve business processes models based on work practice descriptions
Model the System from Adversary Viewpoint: Threats Identification and Modeling
Security attacks are hard to understand, often expressed with unfriendly and
limited details, making it difficult for security experts and for security
analysts to create intelligible security specifications. For instance, to
explain Why (attack objective), What (i.e., system assets, goals, etc.), and
How (attack method), adversary achieved his attack goals. We introduce in this
paper a security attack meta-model for our SysML-Sec framework, developed to
improve the threat identification and modeling through the explicit
representation of security concerns with knowledge representation techniques.
Our proposed meta-model enables the specification of these concerns through
ontological concepts which define the semantics of the security artifacts and
introduced using SysML-Sec diagrams. This meta-model also enables representing
the relationships that tie several such concepts together. This representation
is then used for reasoning about the knowledge introduced by system designers
as well as security experts through the graphical environment of the SysML-Sec
framework.Comment: In Proceedings AIDP 2014, arXiv:1410.322

An agile business process and practice meta-model
Business Process Management (BPM) encompasses the discovery, modelling, monitoring, analysis and improvement of business processes. Limitations of traditional BPM approaches in addressing changes in business requirements have resulted in a number of agile BPM approaches that seek to accelerate the redesign of business process models. Meta-models are a key BPM feature that reduce the ambiguity of business process models. This paper describes a meta-model supporting the agile version of the Business Process and Practice Alignment Methodology (BPPAM) for business process improvement, which captures process information from actual work practices. The ability of the meta-model to achieve business process agility is discussed and compared with other agile meta-models, based on definitions of business process flexibility and agility found in the literature.
