10 Model'repository'in'general.' Model repository Concurrent modifications Change history and audit Versioning/ revisioning of content and branching/ static view defintions Access control Bulk interface Distributed modelling Lightweight and agile development, thus adaptions will not consume much effort A model repository stores entities and the references between them. Model repository stores Metadata where the context (domain) is defined in a formal meta model. The concepts of the model repository are defined in a meta meta model Grimm, Sensler 10

11 Excurse:'Model?' 'MetaUModel?' '' MetaUMetaUModel?'' Portfolio Model the data stored in the repository is the model Program,: P1 Program: P2 Meta-Model The general formal definition of the structure/entities for a concrete domain Portfolio 0:n Program Meta-Meta-Model The formal definition of the concrete syntax for modelling the Meta-Model Class Attributes Carsten Sensler & Andre Karalus, SET 2009, T-Mobile 11 0:n

16 Four'Different'Repository'IntegraCon'Scenarios,' depending'on'the'toube'integrated'repository' 1. SynchronisaCon'of'external'sources'with'one'Repository' 2. SynchronizaCon'of'two'Repositories'with'the'SAME' Metamodel' 3. SynchronizaCon'of'two'Repositories'with'different' Metamodel' 4. Repository'IntegraCon'only'on'UI'level' Grimm, Sensler 16
