[Fiware-apps] IMPORTANT: About WP3 Composition GEs and the Catalogue

[Riss, Uwe]

Dear Javier,

I have checked the WPL/WPA minutes, which say that GE owners are expected to "submit description of GEs that will be available on the FI-WARE Testbed".

That is the status.

Best regards,
Uwe

Subject: IMPORTANT: About WP3 Composition GEs and the Catalogue

Dear Uwe, Torsten, dear colleagues,

Unfortunately, no one from UPM can attend today's conf call. 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UNPUBLISHED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. Am I wrong?

Best regards,
Javier
