Hello, just a brief note regarding some of WebUI and certain other chapters of FIWARE. I've said these points a couple of times during spring in the talks as well, so nothing new really, but summarizing here to clarify: While the POIs & Context Broker work has been good and is fine to report and focus on now, it is good to recognize -- at least internally -- that it is not the full story regarding WebUI GEs and FIWARE integrations. >From my / realXtend point of view, the Synchronization server (Tundra) has often been central (the server core if you look at webui arch pic, where POI is just an optional outlier). Notably regarding Context Broker / NGSI discussion, the Sync GE also is a generic entity-attribute pub/sub system. Just that Sync is optimized for realtime updates, such as moving vehicles or other objects, whereas POI was for static information. They entity-component model, a kind of entity-attribute system, is basically identical in both (the newer POI data model was modeled after the pre-existing Sync one). Whereas CB is kind of for (huge masses of) rarely changing information. But Sync is very limited in other ways: it is basically made for networked games and collaborative apps where there are perhaps a few thousand entities and a few of some tens of clients (like participants in a conference call) -- there is no federation, persistence, and only small scale scaling (perhaps to hundreds or thousands of clients, not millions). All data is in memory of the sync process (which is what you want in a real-time game like pong) etc. Mostly the point is that in the Sync GE we already have an efficient binary protocol for small quick updates in an entity-attribute system, even over UDP(*) when that is supported. But normally over websockets with browsers. Besides the original Tundra implementation, there's now the DFKI FiVES implementation of the same protocol which is very cool. One specific point is that many efforts seem to be dealing with moving objects now, real-time updates to vehicle positions etc. Sync GE AFAIK has the most optimized current implementation that, and furthermore has specific new work planned exactly for movement synchronization for autumn 2015 now. So in the big picture, Sync, POI and CB are all generic entity-attribute systems with some similarities and differences. How to have them work together and develop further is a think a valid design question. There is no crisis, they all work and are used and developed, but I think good to recognize and try to understand the situation. To not loose the full picture with the POI focus. For example to be able to document clearly when to use what, how they can be used together to have both federation/scalability & optimized real-time sync etc. 2cently yours, wishing a good meeting (will not be there, not needed AFAIK), ~Toni (*) For UDP in browsers, we've tested WebRTC data channels (first in the original fiware 3d pong 2 years ago). Which also brings a possible link to WebRTC work done elsewhere in FIWARE, I've actually studied and tested the Kurento signaling server (websockets also) and some of the other techs in streaming oriented GE now in July.
