  • 1. 1 Composing Model Transformations at Runtime: an approach for adapting Component-Composing Model Transformations at Runtime: based User Interfaces Diego Rodríguez-Gracia, Javier Criado, Luis Iribarne, Nicolás Padilla Applied Computing Group University of Almería, Spain Cristina Vicente-Chicote Department of Information Communication Technologies Technical University of Cartagena, Spain Applied Computing Group GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012
  • 2. 2 Index • Our goal • Our proposalComposing Model Transformations at Runtime: o Transformation Pattern o Transformation Schema o Transformation Rules o Rule Selection o Rule Transformation • Conclusions • Future work GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012
  • 3. 3 Our goal - The main objective of our proposal is to achieve the adaptation of user interfaces at runtime. - User interfaces are described by means of architectural models that contain the specification of user interfaces componentsComposing Model Transformations at Runtime: - These architectural models, which represent the user interfaces, can vary at runtime due to changes in the context(user interaction, a temporal event, etc) GUI GUI Video Audio Chat Architectural Model 1 Architectural Model 2 Adaptation Chat Video Audio Process GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012

  • 5. 5 Our proposal - Adaptation of architectural models - @RuntimeComposing Model Transformations at Runtime: - Using M2M transformations - Transformations are also adapted at runtime. - Model Transformations not prepared a priori - M2M is dynamically composed from a rule model GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012
  • 6. 6 Transformation Pattern - Model the structure and composition of our transformation schema elements.Composing Model Transformations at Runtime: - Possibility of changing our adaptation schema - Elements: • TransformationSchema • Metamodel • Model • Transformations: M2M M2T GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012
  • 7. 7 Transformation Schema: An instance of Transformation PatternComposing Model Transformations at Runtime: 1º Rule Selection: is obtained as an instance of the M2M concept Input: the repository model (RRM) and the initial architectural model (AMi) Output: the selected rules model (RMi) 2º Rule Transformation: is obtained as an instance of the M2T concept Input: the rule model (RMi) Output: a new transformation for architectural models at runtime (ModelTransformationi) 3º Model Transformation: is obtained as an instance of the M2M concept Input: the initial architectural model (AMi) Output: a new architectural model at runtime (AMi+1) GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012
  • 8. 8 Transformation Rules Metamodel for transformation rulesComposing Model Transformations at Runtime: Rule Repository Model (RRM) Selected rules model (RMi) The transformation behaviour is defined in the rules: - rule_name: Unique. Identifies the rule. - purpose: Indicates the purpose of the rule. - is_priority: Boolean. It its value is true, the rule must be selected. - weight: The selection process uses this attribute to select the rules.

  • 9. 9 Rule Selection Instance of the M2M conceptComposing Model Transformations at Runtime: The process starts when the system detects that it is necessary an adaptation Input: - Architectural Model (AMi) - Rule Repository Model (RRM) Output: - Selected rules model (RMi) GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012
  • 10. 10 Rule Transformation Instance of the M2T concept The process starts after RuleSelectionComposing Model Transformations at Runtime: Input: - Selected rules model (RMi) Output: - Architectural model transformation (ModelTransformationi) GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012

  • 14. 14 Conclusions • Adaptive transformation for Composing Model Transformations at Runtime.Composing Model Transformations at Runtime: • Transformation pattern/template for adaptation schema • Adaptation schema is also changeable and adaptable • High degree of adaptability • All adaptation elements are based on MDE • Models (architectures, rule repository, selected rules) • M2M (RuleSelection, ModelTransformation) • M2T (RuleTransformation) GRUPO DE INFORMÁTICA APLICADA ICSOFT 2012 UNIVERSIDAD DE ALMERÍA 24-27 de julio de 2012
