Hi - there seems to be an 'x' in the document for Fermin now, perhaps
that is old information though if he can't come now?

I'm in a seminar (ubicomp, open data & 3d web for smart cities) and
need to give a presentation in 20mins .. will check after the talk
etc. if have a chance. Timo Mukari seems to be here too, I figure
someone from CIE is joining at least. (he, Ari or both I guess).

In case I can't join, wanted to note here:

>From the comments and discussion in the doc, it seems that there is
good progress on the NGSI/CB side in V2 for simple HTTP queries which
start to look very similar to the POI queries.

Whether that means that it would make actually sense to use CB (or
that API otherwise) for POIs, I don't know -- looking forward to
learning more based on how the discussions go by folks more involved
in this.

One question, possibly due to my ignorance: I think Fermin noted in
the previous call how the POI with the schema is like a vocabulary,
for a certain application area. Whereas CB at the base is a generic
entity-attribute system.

So is there some mechanism / practice you have with NGSI to introduce
schemas or some vocabularies otherwise? To define data types,
'attribute bags' kind of -- is it ever needed? I'm not sure how the
POI folks see their usages, IIRC someone mentioned validation in the
prev call?

In the 3DUI & Scene synchronization side, where we also have a generic
entity-attribute system, there are many pre-defined so-called
components (a group of attributes for a particular purpose,
basically). The POI component architecture was designed following
that. One usage for those in the 3D apps there is autogenerated GUIs
(in the 'interface designer' GE). So for example when an entity has
position (in the placeable component), the GUI editor for configing
entities shows the correct type of editor for changing the position
automatically (using attribute metadata actually).

Other point here is that NGSI/CB is also not really a generic
entity-attribute pubsub (like I've perhaps mistakingly thought of it
earlier) as it also embeds some kind of knowledge about geopositions,
spatial queries and such -- which makes of course a lot of sense for
IoT. I think that's something for me to study more: how are places and
spaces conceptualized in NGSI/CB .. and see if we're already
compatible enough there for example with the synchronization GE (where
we already have optimized websocket protocol for subscriptions and
many things for dealing with spatiality).
