Introduction to Microservice API Patterns (MAP)

Authors: Olaf Zimmermann, Mirko Stocker, Daniel Lübke, Cesare Pautasso, and Uwe Zdun

Published in: OASIcs, Volume 78, Joint Post-proceedings of the First and Second International Conference on Microservices (Microservices 2017/2019)

Abstract
The Microservice API Patterns (MAP) language and supporting website premiered under this name at Microservices 2019. MAP distills proven, platform- and technology-independent solutions to recurring (micro-)service design and interface specification problems such as finding well-fitting service granularities, rightsizing message representations, and managing the evolution of APIs and their implementations. In this paper, we motivate the need for such a pattern language, outline the language organization and present two exemplary patterns describing alternative options for representing nested data. We also identify future research and development directions.

Model-Driven and Pattern-Based Integration of Process-Driven SOA Models

Authors: Uwe Zdun and Schahram Dustdar

Published in: Dagstuhl Seminar Proceedings, Volume 6291, The Role of Business Processes in Service Oriented Architectures (2006)

Abstract
Service-oriented architectures (SOA) are increasingly used in the context of business processes. However, the modeling approaches for process-driven SOAs do not yet sufficiently integrate the various kinds of models relevant for a process-driven SOA – ranging from process models to software architectural models to software design models. We propose to integrate process-driven SOA models via a model-driven software development approach that is based on proven practices documented as software patterns. We introduce pattern primitives as an intermediate abstraction to formally model the participants in the solutions that patterns convey. To enable model-driven development, we develop domain-specific modeling languages for each kind of process-driven SOA model - based on formal meta-models that are extended with the pattern primitives. The various process-driven SOA models are integrated in a model-driven tool chain via the meta-models. Our tool chain validates the process-driven SOA models with regard to the constraints given by the meta-models and primitives.

Querying Semantic Web Resources Using TRIPLE Views

Authors: Zoltan Miklos, Gustaf Neumann, Uwe Zdun, and Michael Sintek

Published in: Dagstuhl Seminar Proceedings, Volume 4391, Semantic Interoperability and Integration (2005)

Abstract
Resources on the Semantic Web are described by metadata based on some formal or informal ontology. It is a common situation that casual users are not familiar with a domain ontology in detail. This makes it difficult for such users (or their user tools) to formulate queries to find the relevant resources. Users consider the resources in their specific context, so the most straightforward solution is to formulate queries in an ontology that corresponds to a user-specific view. We present an approach based on multiple views expressed in ontologies simpler than the domain ontology. This allows users to query heterogeneous data repositories in terms of multiple, relatively simple, view ontologies. Ontology developers can define such view ontologies and the corresponding mapping rules. These ontologies are represented in Semantic Web ontology languages such as RDFS, DAML+OIL, or OWL. We present our approach with examples from the e-learning domain using the Semantic Web query and transformation language TRIPLE.
