In my day job at ARM I recently led a project intended to create an ecosystem of interoperating IoT systems on our Cambridge headquarters site, a typical business park. In these slides I introduce the idea behind why interoperability is important and the connected assets and their users on the ARM HQ site. I explain how we used a site-wide HyperCat to create an "ARM site IoT directory", and how that helped us as IoT customers and also our IoT-vending suppliers. The project was funded by the UK's Technology Strategy Board, under its IoT Ecosystem Demonstrator competition.

An IoT Hypothesis
Connected assets should be

An IoT Hypothesis
Connected assets should be
able to work together
Reduces costs of deploying assets
and applications, or increases the
benefits realised from them, or both
Things and systems
with information about
the real world
environment
As easily as possible
They can discover, gain access to
and use each others’ resources,
creating an ecosystem of interacting
consumers and service providers

ARM site ecosystem
 A typical business park
 ~1400 people, 4 buildings
 ARM Facilities Management
 Interested in instrumenting car parks,
energy use.
 ARM Sustainable Corporate Development
 Interested in tracking and improving ARM’s
environmental footprint, including buildings
energy use, travel, commutes and home
working
 ARM IT Employee Systems Group
 Interested in systems of general benefit to
employees – email, holiday bookings, etc.
Keen to improve meeting room availability.
 ARM employees
 Interested in own home electricity use, in
finding available meeting rooms on the fly, in
using and adding to the ARM datasphere
generally.
 Service Providers
 EnLight car park lighting
 IntelliSense HVAC plant monitoring
 AlertMe room occupancy and home energy
monitoring
 Service providers’ other customers
 City councils, road authorities, fabs, factories,
homeowners, industrial plant vendors, energy
and telecoms utilities, IoT developers

ARM site is one of numerous ‘contexts’ (and instances
of contexts) in which assets are potentially relevant to
one another
Some primary assets are useful
to one another
… some are obviously
infrastructural, i.e. they can serve
multiple applications. Others won’t
be so obvious
Secondary users often include
dashboards, visualisers, normalisers,
rules engines, analysis tools, research
Use cases for sharing increase with number of feeds
and apps, both of which grow over time
… Access control makes it easy and safe to find useful
combos

Should ARM site IoT assets be able to work together?
Yes!
 ARM is realising additional benefits
 Meeting room availability app(s)
 Yes, there are additional costs
 Interestingly they can all be considered
reusable infrastructure that can be adopted
by ARM IT: root catalogue, sensors, access
points.
 HyperCat approach means suppliers can
integrate without ARM running a big project,
making overall cost much lower than an
traditional integration project.
 Each of the 3 commercial systems are
realising business benefits
 Publishing and indexing feeds lets them offer
their customers similar benefits to ARM
 Their customers can ask their other suppliers
to publish and index feeds similarly
 EnLight: consuming council’s other connected
assets into their EnTalk dashboard
 AlertMe: rearchitected to partition devices
from application
 IntelliSense: publishing feeds to industrial
plant vendors and factory operators

Open IoT Take-Aways
 Connected assets should be able to work together
 Composable data sources and applications do create more value than siloed solutions.
 HyperCat enables composability
 We already knew every device is more useful for being connected. We demonstrated an ecosystem
that makes those devices even more useful for being interconnected.
 HyperCat and tools like FeedLocker let end users invest in their own IoT infrastructure: connected
assets that serve multiple applications.
 It’s about people working well together too
 IoT assets are not public assets – still need to broker access
 Per-context HyperCats encourage innovation, if supported with community, tools, hackathons, access
..
 .. and infrastructure. End users should make IoT infrastructure part of their building upgrade plans.
