The specification will be based on the Simple TOSCA profile specification for NFV with possible changes. The deliverable will contain normative provisions and an informative 16:13:53 mapping between the terminology used in the Simple TOSCA Profile for NFV specification and the terminology used in GS NFV IFA 011 and 014. 16:14:19 #info also doing the state 3 for IFA007 16:19:50 #info Marc made a presentation to the ETSI Plenary on the IM status 16:19:56 #link https://docbox.etsi.org/ISG/NFV/05-CONTRIBUTIONS/2016//NFV(16)000168r1_NFV_Information_Model_Status____Relationship_with_other_SDOs.pptx 16:21:14 https://www.irccloud.com/pastebin/wueJMGEF/ 16:36:58 #info Bryan described the work at the OMA on service enabler virtualization as a use case for modeling 16:37:05 #link http://member.openmobilealliance.org/ftp/Public_documents/TP/2016/OMA-TP-2016-0061-INP_Seville_WI_Wrapup.zip 16:39:51 #info This is an example of a use case, we will use for the Models testing (if we can find an open source implementation) 16:40:47 #info The question was whether we need to look at these use cases from a DSL view or a higher level view 16:43:10 #info Marc's suggestion is to start at the DSL level for use cases as the UML/IM level is intended to be more conceptual and language independent, even use-case independent (the classes do not represent use case considerations rather generic usable concepts that can be implemented thru the DSL) 16:46:17 #info IM's help to assess the consistency of the little pieces of the problem space, e.g. classes, e.g. services, service chain, etc... 16:47:37 #info The IM should also enable the relationship description at the UML level and below. 16:54:06 #info (related to earlier question about where to start in applying use case modeling) It may be useful to start at the UML level for service use cases that may be applied to different service environments, e.g. a web service that can be deployed for browsing, APIs, end-users, and IoT applications. 17:00:49 #info such a web service might include a proxy, cache, and other network functions that can be modeled in terms of their function, relationships, and topology 17:01:31 I will leave the meetbot running until the end of the next session today. 00:03:46 starting the bridge now 00:04:08 if you're here for the meeting let me know 00:15:48 ok, please see the minutes for the meeting if there are any followups needed 00:15:51 #endmeeting
