Issue 13219: Section: 8/8.3.2 Inability to efficiently capture datasets (sysml-rtf) Source: (Mr. Sanford A. Friedenthal, ) Nature: Enhancement Severity: Significant Summary: There is currently limited ability to capture datasets for selected property values. A simple example is the difficulty in capturing the time histories for the position, velocity, and acceleration properties for two different instances of a vehicle, where the vehicle is a block, and the position, velocity, and acceleration are value properties of vehicle. Another example is the need to capture data such as environmental loads data (e.g. temperature, vibration as a function of freq) which is referenced as part of a requirement. Resolution: Defer Postponed to the next RTF Revised Text: Actions taken: January 12, 2009: received issue January 3, 2017: Deferred April 6, 2017: closed issue Discussion: Proposed resolution: Consider creating a stereotype called a Dataset that enables a user to specify a set of properties and their values as a function of time or other property. The data values can be derived from parametrics or a behavior execution, or pre-specified. The dataset should support data arrays, matrices, etc. End of Annotations:===== m: webmaster@omg.org Date: 12 Jan 2009 23:56:43 -0500 To: Subject: Issue/Bug Report -------------------------------------------------------------------------------- Name: Sanford Friedenthal Company: Lockheed Martin mailFrom: sanford.friedenthal@lmco.com Notification: Yes Specification: SysML Section: 8/8.3.2 FormalNumber: formal/2008-11-02 Version: 1.1 RevisionDate: November, 2008 Page: 43 Nature: Enhancement Severity: Significant HTTP User Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; MS-RTC LM 8) Description Issue: Inability to efficiently capture datasets.
