This volume constitutes the proceedings of the 9th IFIP WG 8.1 Conference on the Practice of Enterprise Modeling held in November 2016 in Skoevde, Sweden. The PoEM conference series started in 2008 and aims to provide a forum sharing knowledge and experiences between the academic community and practitioners from industry and the public sector. The 18 full papers and 9 short papers accepted were carefully reviewed and selected from 54 submissions and cover topics related to information systems development, enterprise modeling, requirements engineering, and process management. In addition, the keynote by Robert Winter on "Establishing 'Architectural Thinking' in Organizations" is also included in this volume.

ER2003, the22ndInternationalConferenceonConceptualModelinginChicago, Illinois, hosted four workshops on emerging and maturing aspects of conceptual modeling. While the entity-relationship approach is used to address data (base) modeling, the increasingly connected information infrastructure demands - swers that can handle complexity and can develop models about systems that aremaintainable. Wereceivedsevenexcellentproposalsforworkshopstobeheld at ER 2003, out of which we selected the following four based on peer reviews: - ConceptualModelingApproachesforE-Business(eCOMO2003)brought- gether researchers and practitioners interested in conceptual modeling te- niques for e-business. - The International Workshop on Conceptual Modeling Quality (IWCMQ 2003) concentrated on approaches to quality assurance in the modeling p- cess. - The International Bi-Conference Workshop on Agent-Oriented Information Systems (AOIS 2003) was devoted to investigating the agent paradigm for information systems development. - Finally, theInternationalWorkshoponXMLSchemaandDataManagement (XSDM 2003) addressed the impact of XML on topics like data integration, change management, and the Semantic Web. All four workshops highlighted relatively new viewpoints on conceptual - deling. Conceptual modeling as such has been greatly in?uenced and shaped by the entity-relationship model of Peter Chen. However, new developments like object-orientation and the World-Wide Web require adaptions and new te- niques. No longer can developers assume that they can completely understand or model the information system. The new developments create challenges in various directions; some of these were discussed in detail in the four ER 2003 workshops: E-Business and E-Commerce.

This book constitutes the refereed proceedings of the 41st International Conference on Conceptual Modeling, ER 2022, held in Hyderabad, India, in October 2022. The 19 full and 11 short papers were carefully reviewed and selected from 82 submissions. The papers are organzed in the following topical sections: foundations of conceptual modeling; ontologies and their applications; applications of conceptual modeling; data modeling and analysis; business process; quality and performance; security, privacy and risk management; goals and requirements.

This book constitutes the refereed proceedings of seven workshops and a symposium, held at the 34th International Conference on Conceptual Modeling, ER 2015, in Stockholm, Sweden. The 26 revised full and 8 invited papers were carefully reviewed and selected out of 52 submissions to the following events: Conceptual Modelling for Ambient Assistance and Healthy Ageing, AHA-2015; Conceptual Modelling of Services, CMS-2015; Event Modelling and Processing in Business Process Management, EMoV-2015; Modelling and Management of Big Data, MoBID-2015; Modelling and Reasoning for Business Intelligence, MORE-BI-2015; Conceptual Modelling in Requirements Engineering and Business Analysis, MREBA-2015; Quality of Modelling and Modelling of Quality, QMMQ-2015; and the Symposium on Conceptual Modelling Education, SCME-2015.
