====== Welcome to the Conceptual Modeling Working Group wiki ====== This working group was formed at the Berlin OMG meeting in June 2015. At the meeting, we decided to explore {{:cm_wg_topics.xlsx|these topics}}. The working group generally meets face to face at each OMG meeting, an hour before the Wednesday reception. It also generally meets via telecon about once a month. ====== Working Definitions ====== The first topic on our list was to define the following terms: * **Concept**: (from ISO 1087) "[A] unit of knowledge created by a unique combination of characteristics. Individual concepts correspond to one object, such as 'Saturn' and 'the Eiffel Tower' whereas general concepts correspond to two or more objects which form a group based on having common characteristics or properties, such as 'planet' and 'tower'." * **Model**: (from many sources) "A set of statements made in some modeling language about a universe of discourse in order to communicate common knowledge for some purpose." See the {{:necessary_conditions_characteristics_of_concept_from_iso_704_and_1087-1_2015-09-23-1130-bst_.docx|Necessary Conditions (Characteristics) of the Concept ‘concept’ in ISO 704:2009 and 1087-1:2000}} that Donald Chapin extracted for us. ====== Use Cases ====== The second topic on our list was "use cases / competency questions for conceptual models". Use cases were submitted using a [[http://goo.gl/forms/OTbxmEG9Ej|form]] and automatically appended into a [[https://docs.google.com/spreadsheets/d/1wJqtfcDU3e_AbPbU2QKMRkmx6dkMbWNL_IDyD5t3NJM/edit?usp=sharing|shared spreadsheet]], thanks to Claude Baudoin. ====== Use Case Examples ====== * [[conceptual model for threat and risk information sharing]] * [[eKanban Ontology]] * [[UPDM / UAF / Common Profile]]
