FYI. We'll talk about this item in the call today. BR Pier Da: fiware-wpl-bounces at lists.fi-ware.eu [mailto:fiware-wpl-bounces at lists.fi-ware.eu] Per conto di Juanjo Hierro Inviato: mercoledì 30 novembre 2011 15:39 A: fiware-wpl at lists.fi-ware.eu; fiware-wpa at lists.fi-ware.eu Oggetto: [Fiware-wpl] IMPORTANT: Approach for Architecture Specification Deliverable Hi all, As you know, we have to start working on the Architecture Specifications, which is one of the deliverables that is due in month 9, that is, end of January. My intention is to adopt a pragmatic approach, trying to generate something that can be integrated as part of the GE Open Specifications that we have to produce by month 12. My vision is that all GE Open Specifications should start with a chapter where an overview of the envisioned Architecture for the GE is described. While style would be narrative, the description should be enough concrete, i.e., formulated over actual data type, interface and operation names and elaborating on the base interaction scenarios involving the different entities exporting the defined interfaces. Then, after that chapter, the detailed specification of all data types and interfaces with their operations, are provided (this including signature of operations and accurate description of expected behaviour linked to operations) Then, the Architecture Specification deliverable would be just the result of developing this overview chapter. But nothing better than an example, so let me use one taken from OMG's set of CORBA Services Specifications. Along my many years involved in different standardization efforts, I have found that OMG CORBA Service specs are rather comprehensive and close to what programmers (our ultimate customers!) love to see. Please find enclosed the CORBA Event Service Specifications. What I would then select as the Architecture description are the contents of the following sections: * The whole chapter 1 * Section 2.2 and 2.4 (which some people may have argued should have been included in chapter 1 :-) Note that anyone who reads the mentioned sections would get a CLEAR picture of what is the Architecture of the service and what are going to be the entities and interfaces/operations that will be supported in a compliant implementation. The conceptual and programming model would be also rather clear from a programmer's perspective. Therefore, rather valuable information for an application developer perspective which is what really should matter to us. A side benefit is that what will remain as pending regarding GE Open Specifications will be less, that is, the detailed specification of data types and interfaces/operations. One thing that we will have to define is the set of conventions that we should all follow whenever we need to draw any figure, like figures 1-x or 2-x. For this, Thomas and me will come soon to you with a proposal in short time. Please take your time to analyze this carefully and formulate any question you may have. From now on, I assume that you will start planning activities in Sprint 2 and 3 dealing with development of these specifications within each of your chapters. This may well take the form of Work Items in the tracker. Best regards, -- Juanjo ________________________________ Este mensaje se dirige exclusivamente a su destinatario.
