 +    * e.g. what about new things like: https://​fuchsia.googlesource.com/​docs/​+/​ea2fce2874556205204d3ef70c60e25074dc7ffd/​development/​languages/​fidl/​tutorial.md
 +    * Follow-up on SAT
 +  * API versions
 +    * -> APPFW / Jose
 +
 +  * '​core'​ LTS vs. IVI or Cluster LTS
 +    * depends on changes required e.g. by IC 
 +  * 11/7 - 3 year Yocto LTS proposal was debated in Lyon last week, but no decision was made. No one was opposed to the proposal as it is written, but funding is a question. Proposal is to maintain OE Core, so it still leaves most of our user space and meta-openembedded as question marks for us.  ​
 +    * There were a number of talks last week in Lyon about using a combination of Debian/​Fedora/​CentOS for user space and Yocto for BSPs for LTS in embedded projects. ​
 +      * Stephane posted link for [[https://​wiki.centos.org/​Manuals/​ReleaseNotes/​CentOSStream CentOS Stream]] which is the CentOS plan for LTS and testing. ​
 +      * Will add to SC agenda for next week. 
 +    * 11/21 - SC did not get to this topic, Will be addressed at December meeting. ​
 +    * 12/5 - Following up next week. 
 +    * 1/16 - Added LTS to the SC agenda for February. ​
 +    * 3/26 - Tanikawa is working on this and will provided a verbal update. Will provide another update at the next SAT meeting, ​
 +
 +   * Toyota Code Drop
 +     * 10/10 
 +       * No update. Will need some decisions about how we want APIs to be formatted based on LTS discussion. ​
 +       * Kusakabe-Can will meet with Ohiwa-san next week and provide some feedback to the AGL community,
 +     * 11/7 - Toyota documents are quite large. Were posted on Confluence. Ohiwa-san is working on splitting them up and providing header files. ​ Ohiwa-san will be in Yokohama next week to discuss the next steps with the SC. 
 +     * 11/21 - 
 +     * Notes from SC meeting ​
 +     * Discussed the need to take each of the API documents and deep dive the contents with the appropriate developers within the AGL community. Will need Toyota to do some analysis of the architectural/​ design gaps between AGL and their proposed code changes and work with the community to fill those gaps. For example, the “Peripheral API” document has a lot of details about CAN messaging but it is difficult to determine what the context of API is and how it fits into the overall architecture. There may be parts of it that are already covered by AGL. Suggestion is for Toyota to pick an API to focus on and develop the higher level context with the AGL community to figure out how to fit it into the existing structure. ​
 +     * Ohiwa-san is working on providing the context for the API documents. First task will be System Manager API in the System Service Document (see [[https://​confluence.automotivelinux.org/​display/​TC/​Documents | Confluence]] for more on the documents. ​
 +     * 12/4 - Ohiwa-san presented Persistent Data Manager (Backup Manager) use case ideas.  ​
 +       * Discussion on whether the existing AGL [[ https://​git.automotivelinux.org/​apps/​agl-service-data-persistence/​tree/​src/​persistence-binding.c |data persistence binder]] can be reused/ extended.
 +       * Discussion of whether the backed up data is in a Linux file system, a proprietary file system, or managed memory of some sort (battery backed RAM or flash). ​
 +       * Other requirements need to be documented that were discussed. Ohiwa-san will update and we will review further at the next SAT meeting.  ​
 +     * 12/19 - Ohiwa-san presented some further use cases for persistent storage involving shutdown then rapid restart while meeting the 2 second requirement for review camera after start up. Ohiwa-san will upload the document to the Toyota code drop Confluence page. https://​confluence.automotivelinux.org/​display/​TC/​Documents
 +     * 1/16 - New version of the specification was uploaded to Confluence last week. Code will be uploaded to gerrit in the next week or two. Will be licensed under Apache 2.0.

 + 
 +
 +FOSSology/ License Review
