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

[Javier Soriano (FI-UPM)]

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UNPUBLISHED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
