HP releases e-speak source under GPL/LGPL
December 14, 1999
In an unprecedented move by a Fortune 500 company, Hewlett-Packard Com
pany has made its e-speak source code freely available to software dev
elopers and the public via the Internet at http://www.e-speak.net.
More than 1,000 software developers are working with HP to develop app
lications on the e-speak platform; HP also is working with more than 1
00 business partners to create e-speak services. Examples of such busi
nesses include an engineer dispatch e-service by Ericsson and a multim
edia broker for training services by Helsinki Telephone.
According to Rajiv Gupta, HP's chief architect of e-speak, ``Just as H
TML gave rise to a new set of economic models that radically transform
ed e-business in Chapter 1 of the Internet, we expect a whole new wave
of business models and revenue opportunities to emerge as the Net lea
ps off the PC and into our daily lives. By open-sourcing e-speak, HP i
s providing the technology underpinnings for creating a new breed of i
ntelligent services and appliances. We aim to make it possible for req
uests for services to be automatically brokered, bid and transacted on
the Net, from any device.''
E-speak, announced by HP in May, is an Internet software technology pl
atform developed by HP Labs designed to revolutionize the way people a
nd businesses use the Net. Much like how HTML made it easy for people
to find and access information anywhere on the World Wide Web, e-speak
will make it possible to request and locate services on the Net.
E-speak is central to HP's vision of evolving the Internet from a coll
ection of Web sites accessed with a PC to a network of nimble intercon
nected e-services that come together on-the-fly to solve a problem, me
et a need or complete a task. E-speak will make it possible for Intern
et systems and services to have intelligent conversations. For example
, not only will people be able to put out a request to identify a rest
aurant with room for four, they'll be able to book the reservation ins
tantly from any Internet device.
Innovative Technologies
The e-speak development project has succeeded in leveraging existing t
echnologies and standards. Therefore, even some of the key innovations
in e-speak, such as the specification of negotiation policies and con
tracts that programs can understand and execute, use existing standard
protocols such as XML. Leveraging HP's stewardship of open systems, e
-speak supports key technologies to accommodate a heterogeneous operat
ing environment:
E-speak complements device-to-device communication, such as HP's Chai,
Sun's Jini and Microsoft?s UpnP.
E-speak leverages key collaborative technology-standardization efforts
, such as RosettaNet, ontology.net and Microsoft's BizTalk.
E-speak utilizes open technology standards on the Internet, including
XML, LDAP, HTTP, WAP, SSL, SLP and SNMP.
The e-speak development project has also spawned several new technolog
ies. The most significant innovation in e-speak is the simple but powe
rful service abstractions presented to e-speak users. These abstractio
ns are embodied in a uniform service interface and in a set of uniform
service interactions.
This uniformity is important so that services can dynamically interope
rate without prior pre-negotiated agreements, and so that the knowledg
e of service developers can be leveraged across industries. As an anal
ogy, the power of the Web is the uniform transport and presentation mo
dels of HTTP. This uniformity in the Web allows any browser to retriev
e and present data from any HTTP server; e-speak will perform the same
task for services.
``HP and CommerceNet are working together to create an early reference
implementation of CommerceNet's eCo XML interoperability framework on
HP's e-speak architecture,'' said Randall C. Whiting, president, Comm
erceNet. ``The e-speak vision -- to enable a vast world of intelligent
, ubiquitous e-services across the Internet -- aligns well with Commer
ceNet's mission to promote and advance interoperable electronic commer
ce.''
