Action item from 2022-01-21 IISOMI Meeting notes. UML-YANG tooling discussion is still underway in O-RAN and more meetings will be held next week. no real update - > update will be given if there is in update - considered as done for now Refreshed Action Items none |
| 3 | 15 min | Add values to an existing core-model enumeration | Martin | the ONF OTCC 5G-xHaul group would like to get guidance how to add microwave specific layer-protocol-names to core-model:layer-protocol-names (e.g. microwave-physical-section, microwave-section, ....). More abstract: How can a conditional package add values to an existing (extensible) core-model enumeration? To demonstrate, create a enum and then extend the enum using either specify or generalization. Determine how to display this in GenDoc. Determine the guidelines needed to convert this structure to YANG. Initial thoughts are to ensure isLeaf = false so Identity is used in YANG. For example the core model enum would be the base and the specify or generalization would extend the base identity. Scott Mansfield Demonstrate small example of enums with gendoc |

Post call email from Italo: 2022-02-11: In order to be able to compose the target path of the two «Specify» relationships the class diagram below has been extended with the greyed out "non existing" object class and composition relationships.
Andrea Mazzini will draft rules for the UML Modelling Guidelines for creating the target paths; this is part of the existing action item "Improve explanation of target sterotype string content formation in the UML Guidelines". Discussion will continue in two weeks. | |

November 19 discussion: The TR-512 v1.5 Core model was developed using Eclipse 2019-09. It the model can migrate to 2020-06 seamlessly, Q14/15 might move G.7711 v4.0 (12/2021 consent) also to Eclipse 2020-06. To verify the seamless migration:

| 14 | 0 min | Papyrus-Model2Doc feature | Prior discussion: 2021-05-28 IISOMI Meeting notes #3 2022-01-21 post meeting notes: Scott Mansfield found the following links to various update sites and performed some tests:
The last successful build (model2doc 0.8.0) works fine in 2021-12 (4.22) (Eclipse 4.22 and Papyrus 6.0). Regarding 2020-06 (4.16), none of the found Model2Doc versions works. Even with Eclipse 2021-12 (4.22) but Papyrus 4.8, Model2Doc does not work. The conclusion so far is that only version 2021-03 (4.19) - Papyrus 5.1 and later seem to work with the 0.8.0 Model2Doc version. 2022-01-28 No update. 2022-02-04: No discussion.
