glue.things is a mashup platform that connects the Internet of Things with the Internet of Services. It provides tools for developers to integrate hardware devices through a REST API and client libraries that support various protocols and platforms. glue.things aims to address security, application development interfaces, and distribution of mashup applications through a marketplace. It seeks to improve upon proprietary M2M systems and other IoT toolkits by offering these capabilities through a cloud-based platform. Examples of potential applications that could be built include connected health and home automation. The presentation discusses standardization efforts through groups like W3C and ETSI and how glue.things relates to these efforts.

 High-end M2M Systems:
 Mostly industry-driven custom solutions
 Not focused on Web, no sharing and marketplace concept
 Can be complex because of proprietary and distributed tools
 Similar web-centric toolkits with focus on application development for
hardware micro controllers
 glue.things Key Differences:
 Security and trust: guarantee the correct processing of security
critical data, efficient certification and validation of information flow
characteristics of mashup applications
 Developers portal: UIs, visual mashup editor for stream processing
(condition statements, triggers, actions, alarms, operations)
 How services are delivered: marketplace for mashup applications,
cloud approach, analytics for mashup usage and distribution
MANY OTHER INTERNET OF THINGS TOOLKITS

 Access and manage devices with the glue.things REST API and
client libraries. Supported protocols: HTTP/TCP, STOMP/TCP,
STOMP/WS, MQTT, CoAP, FAMIUM IoT (gateway to TV sets, set-
top boxes, tablets and smartphones in the home environment)
 glue.things supports various software and hardware combinations
needed to create mashup applications for the Internet of Things
 Client libraries for a variety of programming languages and
platforms: Android, iOS, Spark, Flyport, Arduino, Raspberry Pi, mbed
– ARM® microcontrollers, etc
 glue.things API exploits the simplicity and power of the well-known
REST implementation with the support of JSON and XML data
formats

 Home and appliance power monitoring
APPLICATION EXPERIENCE

Various efforts toward standardization for the Internet of Things
W3C WEB OF THINGS
W3C Interest Group on the Web of Things
 Key technologies for Web of Things: REST, CoAP, XMPP, Web sockets, webRTC, MQTT, XML
schema, linked data, JSON, JSON-ld, schema.org, mashups
 The domain is so broad and fragmented. Defining standards is really hard.
 How to break up the vertical software silos? Build the Web of services.
 Web of Things should be an application layer of the Internet of Things
 Conclusion: Outline use cases and best practices to build the WoT. This is better as to build new
standards.
 Positioning of glue.things:
 Builds on key technologies for the Web of Things
 Contributes to an interoperable approach for connecting the Internet of Things with the Internet
of Services

ETSI M2M
ETSI M2M
 ETSI M2M 690 good for industrial implementations but not in the connected home and consumer
environment.
 Missing concepts regarding device discovery, indoor positioning, data subscriptions, identity
management, semantics and meta data
 Barriers to implement ETSI M2M 690:
 is mostly supported by operators
 less reference implementations
 the core architecture with two levels to store data is too complex for consumer devices
 the subscribe / notify mechanism is not appropriate
 mid interface is good for standardization but prohibitive from a performance perspective
 Positioning of glue.things:
 Provides an agile platform across devices, communication, data and APIs by addressing ETSI
missing concepts and implementation barriers
