Re: HA Object Model or Taxonomy?

[alan.trevennor@xxxxxxxxxx]

FYI of everybody here who might be interested: For your convenience, I
have=
uploaded a 5-page VSCP overview (copied from the VSCP Wiki pages) to the f=
iles section of this forum. If you have any interest in the base
technologi=
es of HA I think you'll find it an interesting read worthy of your time.


Hi Ake,

Well, I don't know what happened. I posted quite a long reply to you on
thi=
s one a few days ago, but it's never appeared here!=20

The essence was this.

1) Thanks for letting us know about VSCP

2) As you suggest, it does seem to achieve very similar goals of
classifica=
tion to those we had been discussing here in this forum, but VSCP does it
b=
y categorising and classifying event types and sources rather than by the
f=
ormal object model we had been discussing. To some extent this is a
semanti=
c difference, but the VSCP model does seem to me to mandate a particular
HA=
network infrastructure, in which all nodes can "hear" each
other's events =
all the time.=20

3) Happy to see that you guys also believe that most so-called standards
bo=
dies concerned with HA are actually closed-off "rich men's"
clubs, run for =
by and for the benefit of large corporations - and that this is a major
bar=
rier to HA truly attaining take-off in the mass market.=20

4) Happy to see that one of the network types that VSCP has been
implemente=
d upon (as well as CAT5/6 wired and WiFi Ethernet and RS-232) is the CAN
bu=
s. I have long thought that CAN is an ideal network for HA because it's
che=
ap, can be daisy chained and if you use CAT5 cables, there are spare wires
=
in the cable to carry power to HA peripherals, saving the need for loads
of=
little local power supplies.=20

5) I need to build some minimal VSCP hardware and play around with things
t=
o get a feel for the approach, and to see if it meets the goals that
origin=
ally raised this topic to address. So, give me a few weeks to slot that in
=
around other things and I will come back and write a full reaction and
appr=
aisal of VSCP. My gut feeling is that - although it's a different way to
do=
what we had in mind - it should work just as well, but being a "hands
on" =
kind of person, I need to see it working and play around with it.=20

Many thanks
Alan T


P.S> I have kept a copy of this post in case Yahoo loses this one
