16:02:20 <bryan_att> Topic: Agenda
16:04:02 <bryan_att> #info Agenda is OK
16:07:58 <bryan_att> #info Plans for Colorado is to (1) generate test framework for the models validation
16:08:58 <bryan_att> #info High-level focus will be on assessing the state of IM at ETSI and relation to the DSLs of TOSCA, YANG, etc
16:10:45 <bryan_att> #info ETSI specs and models are UML-based (IFA015), IFA011 goes into details such as element hierarchy in a text/table presentation, still at stage 2.
16:13:22 <bryan_att> #info The work of assessing/normalizing/codifying in the SOL group, e.g. SOL001 (TOSCA-based NFV NSD), is to develop stage 3 specs.
16:13:53 <bryan_att> #info Mark: The scope of this work item is to develop a data model specification for NFV descriptors fulfilling the requirements specified in GS NFV IFA 011 and NFV GS NFV IFA 014. 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 <bryan_att> 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 <bryan_att> #info also doing the state 3 for IFA007
16:19:50 <bryan_att> #info Marc made a presentation to the ETSI Plenary on the IM status

16:36:58 <bryan_att> #info Bryan described the work at the OMA on service enabler virtualization as a use case for modeling

16:39:51 <bryan_att> #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 <bryan_att> #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 <bryan_att> #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 <bryan_att> #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 <bryan_att> #info The IM should also enable the relationship description at the UML level and below.
16:54:06 <bryan_att> #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 <bryan_att> #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 <bryan_att> I will leave the meetbot running until the end of the next session today.
00:03:46 <bryan_att> starting the bridge now
00:04:08 <bryan_att> if you're here for the meeting let me know
00:15:48 <bryan_att> ok, please see the minutes for the meeting if there are any followups needed
