I will forward the email Matteo has sent me to the WP3 list because it contains very useful information about how to complete the entries in the catalogue and how to organize the information. We should use it when adding new entries. Torsten, following your instructions, I will not make the two GEs public for the moment. Instead, I will create a new entry for the Wirecloud mashup platform. This makes sense to me. I didn't take this decision from the very beginning because, as you explained yesterday, in WP3 we agreed a different definition for GEs. But it makes sense to me to introduce the notion of "Enabler" to refer to a particular implementation of a GE (or of part of it, as is the case for our Composition GEs) which is to be offered through the catalogue. Horst has to do the same for the "Mashup Factory" Do you agree Horst? The entries from Ericsson can be considered already aligned with this decision. Do you agree Calin? Later, we can ask Matteo to remove the entries for the GEs I created a couple of days ago. In the meantime, we can reuse some content from these entries. For example, when I highlighted the relationships among different entries in the catalogue: the composition GEs and the Marketplace, Store, Service Description Repository, Service Instance Registry... Does this make sense for you Matteo? Best regards, Javier 2012/7/25 Leidig, Torsten <torsten.leidig at sap.com<mailto:torsten.leidig at sap.com>> Hi Javier, I agree, we should only put the specific enablers into the Catalog. So the generic "Compsition Editor" should be removed and "Mashup Factory" and "Wirecloud" should be added. In some cases it is not possible to separate the Composition Editor and Execution. In these cases I would argue that there is one specific enabler in the catalog called for example "Mashup Factory", which comprises two GE actually.

Indeed, the first paragraph is a good summary of what we have agreed/achieved in WP3. I got surprised when I surfed the catalogue and found a great level of "freedom" in what is considered as a GE, that may confuse its users. Torsten, I still have a couple of doubts regarding WP3 GEs: When adding our Composition GEs to the Catalogue, I used the same terminology as in: https://forge.fi-ware.eu/scm/viewvc.php/trunk/FI-WARE/Apps/?root=fiware This is why I added two separate GEs: "Composition Editor" and "(Composition) Execution Engine" instead of a single "Composition GE". Please note that in the catalogue "Execution Engine" appears out of context and hence the prefix "Composition". Moreover, if you enter the "Composition Editor" directory: https://forge.fi-ware.eu/scm/viewvc.php/trunk/FI-WARE/Apps/CompositionEditor/?root=fiware You can find the current implementations of that GE made from assets of the individual partners: * Mashup Factory (https://forge.fi-ware.eu/scm/viewvc.php/trunk/FI-WARE/Apps/CompositionEditor/MashupFactory/?root=fiware) * Wirecloud (https://forge.fi-ware.eu/scm/viewvc.php/trunk/FI-WARE/Apps/CompositionEditor/Wirecloud/?root=fiware) Following the same idea, I added Wirecloud as an Instance of the "Composition Editor" GE in the catalogue, but the other instance (the "Mashup Factory") is still missing. I imagine that our colleagues from DT will be responsible for providing the content, but I'm not sure if they will have the rights to do so because for the time being I'm the owner of the GE. Finally, if you enter the "Execution Engine" directory: https://forge.fi-ware.eu/scm/viewvc.php/trunk/FI-WARE/Apps/ExecutionEngine/?root=fiware You will see that "Wirecloud" is replicated there. This is because Wirecloud is an instance (OSS reference implementation) of both the Composition Editor and the Execution Engine GEs. The same will occur in the catalogue: Wirecloud will appear as an instance of both GEs. Am I right? Does it make sense for you? Last, but not least: regarding the "ownership" of the GEs. I think I'm now the "owner" of both the Composition Editor and the Composition Execution Engine GEs just because I created the two entries in the catalogue :-( Of course I will agree with any change in this respect. And of course I volunteer to upload / copy&paste any information you provide (instances, descriptions, documentation, etc.). Best regards, Javier 2012/7/24 Leidig, Torsten <torsten.leidig at sap.com<mailto:torsten.leidig at sap.com>> Hi Matteo, I think there is still a lot of confusion. I hate to re- open the discussion what a GE actually is. For WP3 we more or less agreed, that a GE is a collection of generic functionalities, which can be accessed by a set of API (Open Specifications). Composition of services is such a generic functionality. It now happens that we have 4 different implementations (different mechanisms, paradigms, technologies) for this GE. On top of this very generic GE one can have specific GE, which reduces the options for the technologies and APIs. We haven't done this yet for the Composition but possible specific GE could be Mashup Composition, Data-driven Composition, Process-driven Composition, and Semantic-driven Composition. What we currently have is 4 different implementations of the GE made from assets of the individual partners. Some of them are only provided as a service (no code will be available for developers) some are Open Source and the code could be downloaded to run an own instance. I know other chapters (esp. Ch 9 ) has a slightly different view. You see a GE as a specific piece of code (or also a concrete instance exposing their services on certain endpoints?) that can be used by the developer to incorporate it within new applications. Therefore a sentence like "sell and advertise a GE" via the Catalog raises confusion. To make it very explicit: Should we make an entry in the catalog even if we provide only a service on demand and do not deliver any code or an instance in the Testbed infrastructure?

What a GE is will be up to each GE owner and each wp leader. If the Ericsson Composition Engine can be used a a stand alone application why not considering it a GE? If there is an instance of the engine running on the Testbed, why not considering this as a GE? It will be the GE providers (in line with the WP rule and policy) which should decide the strategy on what publish and how. The Catalogue is just a place where it is possible to sell and advertise about the GEs the PPP stakeholders and not only. In this respect, we suggested to publish before those GEs available on the Testbed and later the other just to be aligned with the Testbed and avoid giving false expectations.

We will any case catch up through the minutes. Nevertheless, we have some questions and concerns regarding a recent mail we've received (yesterday) from Osama Sammodi (from WP9). Osama asked us to provide in the FIWARE catalogue ( http://fi-ware.cloud.labs.ericsson.net/) information for the Composition Editor GE we are responsible for. Uwe, could you please include this matter in the agenda for today's conf call. End of July is a hard deadline to get it done. I think there is a general misunderstanding because most of the entries in the catalogue represents products (i.e. instances) instead of GEs on their own. For example, concerning WP3, Ericsson has already added the following entry: --- Ericsson Composition Engine<http://fi-ware.cloud.labs.ericsson.net/node/104> (http://fi-ware.cloud.labs.ericsson.net/node/104) The Ericsson Composition Engine is a toolset for creating and executing composed services and applications. It consists of a Composition Editor and an Execution Engine. --- Which clearly (at least for me) represents one instance of the Composition Execution Engine GE, but not the GE itself. Moreover, the description references the actual GEs that instance "implements": Composition Editor and Execution Engine. Am I wrong? The same occurs with other entries. For example: CEP GE refers to IBM technology: http://fi-ware.cloud.labs.ericsson.net/node/146 BigData Analysis refers to some components (SAMSON Platform, MongoDB, Apache HDFS): http://fi-ware.cloud.labs.ericsson.net/node/158 etc. The entries for "Service Description Repository" and "Marketplace", IMHO, are by far the best examples and reflect accurately the concept of GE. We should follow the same schema for the rest of GEs, shouldn't we? For the time being, in order progress in the matter, I have created two entries: Composition Editor<http://fi-ware.cloud.labs.ericsson.net/node/166> (http://fi-ware.cloud.labs.ericsson.net/node/166) UNPUBLISHED This Generic Enabler helps either the service provider or the end user (prosumer) to create composed services (from the back-end perspective) and application mashups (from the front-end perspective), respectively, in a graphical way APPLICATIONS/SERVICES ECOSYSTEMS AND DELIVERY FRAMEWORK Composition Execution Engine<http://fi-ware.cloud.labs.ericsson.net/node/170> (http://fi-ware.cloud.labs.ericsson.net/node/170) UNPUBLISHED Exposes and executes the composed services which result from using the Composition Editor Generic Enabler or are defined in a execution language supported by the tool APPLICATIONS/SERVICES ECOSYSTEMS AND DELIVERY FRAMEWORK Please find attached a doc with most of the content I've created for each entry. If you want to change or add anything, please let me know. For the time being, they are "under revision" and I'm not sure if you can edit my entries (to change the description of the GEs, to include new instances, etc.) or even see them. If necessary, I can share with you my credentials (user/password) I'm not sure about what is expected to be included in the "downloads" and the "documentation" sections: downloads/documentation regarding the GE? downloads/documentation regarding each instance? For example, in Ericsson Composition Engine<http://fi-ware.cloud.labs.ericsson.net/node/104> (http://fi-ware.cloud.labs.ericsson.net/node/104) Ericsson has included the "Ericsson Composition Engine, Advanced Composition Editor User's Guide", which refers to an instance of the Composition Execution Engine GE.
