2021-06-16 13:05:48 +0100 | edited answer | What is the difference between FIWARE foundations and FIWARE Community? FIWARE FOUNDATION The FIWARE Foundation is the legal independent body providing shared resources to help achieve the FIWARE mission by promoting, augmenting, protecting, and validating the FIWARE technologies as well as the activities of the FIWARE community, empowering its members including end-users, developers and rest of stakeholders in the entire ecosystem. The FIWARE Foundation is open: anybody can join contributing to transparent governance of FIWARE activities and rising through the ranks, based on merit. FIWARE Foundation is a non-profit organization that drives the definition and encourages the adoption of open standards (implemented using Open Source technologies) that ease the development of smart solutions across domains such as Smart Cities, Smart Energy, Smart AgriFood and Smart Industry, based on FIWARE technology. Founded in 2016, the foundation has Atos, Engineering, NEC, Red Hat, Telefónica, and Trigyn Technologies among its Platinum members. FIWARE COMMUNITY The FIWARE Community is an independent Open Community whose members are committed to materialize the FIWARE mission, that is: “to build an open sustainable ecosystem around public, royalty-free and implementation-driven software platform standards that will ease the development of new Smart Applications in multiple sectors”. The FIWARE Community is not only formed by contributors to the technology (the FIWARE platform) but also those who contribute to building the FIWARE ecosystem and making it sustainable over time. As such, individuals and organizations committing relevant resources in FIWARE Lab activities or activities of the FIWARE Accelerator, FIWARE Mundus, or FIWARE iHubs programs are also considered members of the FIWARE community. |

2019-12-03 21:50:15 +0100 | commented answer | fiware-service in Orion 2.2.0 I don't agree with the recommendation on not using servicepath. Service path is an additional level of grouping that you can use if service is not enough. The problem of "not finding entities" would happen exactly the same for service so the rationale of the recomendation is not clear to me. |

2016-05-05 17:57:18 +0100 | answered a question | how can I use the context broker using Java, is there any API? At the present moment, it isn't any "official" Java-based client framework for the NGSI API implemented by Orion Context Broker. Some users have developed their own (e.g. https://github.com/jonaslins/fiwareOr...) but we don't know about their maturity or if they are mantained or not. I'd suggest your contact these users directly. You could use generic REST client frameworks in Java (you could have a look to this question at SOFfor some alternatives). Maybe the following package from Cygnus (which acts as REST client to interact with Orion and CKAN) could be useful: https://github.com/telefonicaid/fiwar... |

2015-11-04 03:16:57 +0100 | answered a question | Scalability of Orion Orion can scale horizontally (there is an interesting post about it at SOF, which I recommend to read). We haven't tested Orion in the scenarios you mention (five or six figures of events per second) but with a conveniently sized infrastructure it should be theoretically possible. Thus, our recommendation is to start with a single Orion node (properly sized, see some hints here), start injecting load and when the limit is reached, add a new Orion node or MongoDB shard (you would need to check which one is the bottleneck in your case). Continue increasing load an adding new resources until you reach the required load. For us, it would be very interesting to know the result of such tests if you do them at the end. |

2015-06-24 03:32:00 +0100 | answered a question | Stackoverflow or ask.fiware.org? It depends on the question. If the question is specific on a GEi (such as Wirecloud, Orion, etc.) and is about programming, API usage, how to run the GEri, etc. the right place is Stackoverflow. You can have a look to existing question in Stackoverflow to get an idea of the kind of questions that should be asked there: Wirecloud or Orion. If you use StackOverflow don't forget to add the label corresponding to the GEi, e.g: "fiware-wirecloud" or "fiware-orion". If there is no label for the GEi, then use the generic "fiware" label. This is importante: using these labels is the only way our support staff realizes a new question has been posted in StackOverflow. For any other question about FIWARE, please use ask.fiware.org. However, don't worry too much :) In the case you use ask.fiware.org for a question that should be in Stackoverflow you will be redirected to the other place or vicecversa. |

2015-06-23 04:56:57 +0100 | answered a question | can I deploy a GE outside the FIWARE Lab? As general answer, yes, you can. FIWARE GE are open source and most of them provide a packaged version (RPM, Deb, etc.) that can be deployed in any host, either inside FIWARE Lab or not. You can even deploy GE in your own premised in physical servers. In some cases, they are even more advanced possiblities, like docker containers or VirtualBox images (the previous links point to examples for Orion Context Broker). |

2015-06-23 04:45:26 +0100 | answered a question | what is a FIWARE GE? and a GEi? A GE (whics stands for "Generic Enabler") is a sofware component definition based on an open specification. For example, the Publish/Subscribe Context Broker (sometimes referred as Context Broker for short) is one of the FIWARE GEs. A GEi (which stands for "GE implementation) is a a particular implementation of a given GE. For example, Orion Context Broker is a GEi of the Publish/Subscribe Context Broker GE. A given GE may have several GEi (some of them even developed by third-parties outside FIWARE, given that the specifications in which a GE is based are open). There is a third key term: GEri (which stands for "GE reference implementation"). A GEri is a particular GEi of a given GE which is provided by FIWARE as a reference implementation of that GE. For example, it happens to be that Orion Context Broker is not only a GEi for Publish/Subscribe Context Broker GE, but also a GEri for that GE. |
