MultiSpeak Approach

• Data objects are formalized in an XML Schema
• Schema is highly extensible
• New objects can be added
• Existing objects can be extended
• Messaging components defined using Web Services
• Graphical constructs sent as XML in standard
  Geography Markup Language primitives, not
  proprietary graphics formats
• GML is a standard issued by the OpenGIS
  Consortium, Inc.

6
Communications Modes

• File-Based Data is buffered and sent in
  batches
• May be automatically scheduled or ad hoc
• Can be dump or incremental update
• Batch that is automatic and fast enough is
  indistinguishable from real-time
• Soft real-time Happens as soon as possible, no
  intentional delays or buffering.
• Version 3.0 uses Web Services
• Supports both request/response and
  publish/subscribe

7
Why are Web Services Important?

• Supported by all computing platforms and
  programming languages that support a web server
  implementation is platform and language
  independent.
• Interfaces documented in computer-readable file
  called a web services description language (WSDL)
  file.
• Simple and fast for programmers to implement
  software toolkits read and build program stubs
  using the WSDL.
• Client does not need to know details of server
  implementation, just how to call the web service,
  which is defined in WSDL.

8
What Benefits Do Utilities Get From Web Services?

• Vendors can build new interfaces quickly and
  cheaply.
• Context and meaning of data is well-defined. All
  programs use data in the same way, reducing
  confusion.
• Web services implementations lead to universal
  data bus (any program can get any data, even if a
  point-to-point interface is not defined).
• Web services code is modular and more
  maintainable.
• Utilities can directly access data, even without
  vendor-developed interface using standard
  Microsoft Office applications and a free web
  services toolkit.

9
Applications vs. Functions

• Applications are software products
• Functions are theoretical capabilities of
  applications
• Using functions in MultiSpeak3 spec
• Each vendor will determine which functions their
  applications offer

MultiSpeak3 Process Model
11
Why Differentiate Applications Functions?

• 1) Two applications of same type have different
  functions

Outage Detection
Load Profile
Connect - Disconnect
Meter Reading
Meter Reading
AMR Product A
AMR Product B
2) The same function is served by different
applications (i.e. outage detection) Outage
detection device AMR CIS outage function
IVR

To Learn More

• Download the V3.0 specification or Utility Users
  Guide from web site
• Browse the web services on the web site or
  download version for local hosting
• Watch the web site for developments and subscribe
  to the MultiSpeak mailing list (www.MultiSpeak.org
  )

Summary

• V3.0 available now
• Includes batch and web services interface
  definitions for nearly all applications in common
  use in electric distribution utilities
• MultiSpeak V3.0 interoperable products are
  available, more in development
• Small utilities should ask software vendors about
  their plans to support MultiSpeak
• Vendors and larger utilities can download V3.0
  spec and incorporate it in their applications
