[GAIA-X][Service Composition WG][Skipping meeting tomorrow / next meeting next week on 17/03/2022]
by Djamal Zeghlache March 17, 2022

March 17, 2022

Dear Service Composition Working Group Members, (@Giuditta: can you please _cancel tomorrow's only_ Service Composition meeting. Other future and regular slots are unchanged and remain active). /_We have to skip the visio/teams meeting of tomorrow__, of the service composition working group_, for unfortunate conflicts in my schedule. I was unable to resolve the collision/. This is quite unusual for me to do so, but hopefully it is not that critical at this stage since I am yet to build a "relevant" composition example to bootstrap the working group work fruitfully. I think we can use the time in between to consolidate the example and have an efficient meeting on 17/03/2022, Thursday of next week. Meanwhile Anja kindly sent us pointers on Self Descriptions from the Service Characteristics working group that I am repeating below, and that I recommend you to analyze and think about in terms of service composition. We need also to establish a link with the compliance and trust frameworks to embed compliance and trust in our work. Copied from Anja's message that we received on our mailing list: Self Descriptions for analysis and exploitation by service composition. * *Bare Metal Service Offering*: https://gitlab.com/gaia-x/gaia-x-community/gaia-x-self-descriptions/-/blob/… (WIP) * *Virtual Compute Service Offering*: https://gitlab.com/gaia-x/gaia-x-community/gaia-x-self-descriptions/-/blob/… (WIP) * *K8s Service Offering:* https://gitlab.com/gaia-x/gaia-x-community/gaia-x-self-descriptions/-/blob/… (WIP) Be aware, however, just like Christoph mentioned these are not service compositions, but description frameworks. Evidently no service composition without descriptions and descriptors, without discovery/matching/recommendation mechanisms. Therefore, it is important that we take the other working groups work into account and build upon their frameworks and feedback if we identify missing elements and gaps later on when we roll out the service composition processes and workflows to build the service composition model. I will notify you when I have documents and examples ready on the shared space so we can prepare the meeting of Thursday 17/03/2022 ahead of meeting time. *Again, my apology for cancelling tomorrow's meeting, only. We will be back to normal schedule every Thursdays from 2 to 3 pm, as of next week.* BR, Djamal Zeghlache -- Djamal Zeghlache ________________________________________________________________________ Djamal ZEGHLACHE, Professor Directeur Département RS2M (Réseaux et Services Multimédia Mobiles) Télécom SudParis, Institut Mines-Télécom Head Wireless Networks and Multimedia Services Department Télécom SudParis (Education & Research Center of Institut Mines-Télécom) Mobile Phone : +336 30 67 73 28 Palaiseau office phone : +331 75 31 44 23 Evry (secondary site) Phone :+331 60 76 47 15 e-mail :djamal.zeghlache@telecom-sudparis.eu (or @it-sudparis.eu) ________________________________________________________________________ Address@Palaiseau : 19 Place Marguerite Perey, 91120, Palaiseau, France Office Number: 4A243 Address@Evry (secondary site): 9 rue Charles Fourier, 91011 Evry, France Office number: A104-01 ________________________________________________________________________

Hi all, I've heard that you are looking for an example for service composition. WG Service Characteristics is already working on three examples for composed services. Maybe you want to have a look on it. Feel free to copy the examples and/or to extend then. WG Service Characteristics will be happy to assist you especially with providing Self Descriptions for your composed service. * *Bare Metal Service Offering*: https://gitlab.com/gaia-x/gaia-x-community/gaia-x-self-descriptions/-/blob/… (WIP) * *Virtual Compute Service Offering*: https://gitlab.com/gaia-x/gaia-x-community/gaia-x-self-descriptions/-/blob/… (WIP) * *K8s Service Offering:* https://gitlab.com/gaia-x/gaia-x-community/gaia-x-self-descriptions/-/blob/… (WIP) Best regards, Anja -- *Dr. Anja Strunk Team Lead Cloud Innovation * ** Cloud&Heat Cloud&Heat Technologies GmbH Königsbrücker Straße 96 (Halle 15) | 01099 Dresden *+49 351 479 367 00* *anja.strunk(a)cloudandheat.com | **www.cloudandheat.com* <https://www.cloudandheat.com> * **Think Green.
