Boris, The context in CEP has been discussed with Juanjo and also discussed was the difference between this and the context management GE. The only thing that is the same is the term not its meaning Context in the CEP is defined as "Context is a named specification of conditions that groups event instances so that they can be processed in a related way." It also has nothing to do with an entity. It is part of the programming language of CEP to define the context in which event processing logic executes: For example: detecting a sequence of Buy and Sell events The context maybe during the day from 8 until 17 or from the opening of the trading until close (those last are events and not absolute time) The context could also (doesnt have to) say something about how to group these events based on some attribute value they all agree on (such as the same Stock or the same Customer or that they both have the same Price) As I see this - there is no need to connect the two GEs processing wise - there is need to connect them where by events can contextually be published or subscribed to.

The document is made available under review session of our WP docman under the link https://forge.fi-ware.eu/docman/view.php/9/250/Data+and+Context+management-TNA+comments-12072011_Guy%26BorisAnswers.doc in order to avoid your (additional J) complains about the mail saturation. Juanjo please consider this document for integration of changes/comments and provide then the document to Orange Labs people (reviewer) or enable her/him access to our private WP folders and files.

My first comment is that there is no description of the architecture in the way that you have some arrows on the first pictures and no one are explained so you have a collection of GE but we do not know how they work together. And there is no comment on the relationships with the other WP. I found once a reference to WSN just to write that the GE could be used in this environment. This is really weak for some GE which are previously named "Support Services". My second comment is that what you call "high-level standard context wrappers" are not related to context but are some specific cases of data-mining for dedicated use-cases (social networks, opinion, mobility...) The concrete GE is toolbox for Data and Events mining but you cannot keep some dedicated applications in this way in data & context management. My third comment is that we are describing, for this first version, a high-level architecture. In this part, we have partners who have described their tools without any efforts to adapt vocabulary. I'm really not happy to have pushed IoT team to work on a generic architecture with clear functionalities (and everybody did the job) and to find partners assets as part of the architecture in Data & Context management WP. Some of the descriptions are dealing with API and you expect that the Usage Area projects with partners which are not ICT oriented, will agree with this kind of description? In the same way, the unique selling points are sometimes dedicated to developers directly and not really for the stakeholder as ASP for example. Regarding more specifically the question marks with IoT, the CEP refers to the "Event Processing in Action" a book which is not in the list of reference. The approach is too much related to a defined sequence of actions which is a static view and does not take into account cross-domain activities (which is the baseline of the PPP FI itself) because this approach is a silo-approach. You have to know the processes in your silo to be able to prepare the right rules. CEP and pub/sub mechanisms are fully complementary because pub/sub with no official broker but datamarket places will propose the relevant openness to share data through several silos. The GE Big Data should be very relevant for that. I don't know if people who have described CEP are aware of physical pub/sub routers when you don't need a broker. We need this kind of networks for IoT and we should replace these real routers by middleware hosted in different places and our gateways are one of these places. Another point is that nothing is explained regarding multi-brokers systems and how it is possible to build a whole process through their environments and their knowledge of published data. We can discuss all these issues tomorrow morning but we have also to other partners who will provide some comments on this part for Wednesday morning.

Hierro" Objet : Peer review of the IoT and Data/Context Management chapters Hi Thierry and Lorant, We hadn't contact to sync on how we are planning to orchestrate the peer-review of the IoT and Data/Context Management chapters ... I can tell you that, on the side of the Data/Context Management chapter, we will carry out a peer review of it and provide comments by Monday EOB as planned. This peer review will mostly involve other members of the Data/Context Management WP since I already did my peer review as you know :-) Regarding review of our chapter by you, I want to let you know in advance that we plan to update the section dealing with the description of the Publish/Subscribe Broker GE and the Semantic-related GEs ... They should be delivered in an update to you by monday, around 11:00am ... so you may leave review of these sections to the very end ... When do you plan to have it ready ? I believe we can relaxed a bit the milestone (monday EOB) to be tuesday 12:00pm so that you have the necessary time to review the updates on these sections.
