Cutting Edge: NOAA builds AJAX-based Data Viewer
Joab Jackson, Government Computer News
The National Oceanic and Atmospheric Administration's Pacific Marine
Environmental Laboratory has released a browser-based application
called the Dapper Data Viewer for viewing oceanographic and atmospheric
data. DChart, as it is also known, enjoys a particularly rich
feature-set, thanks to the use of an emerging Web application
technology called Asynchronous JavaScript and XML (AJAX). Pacific
Marine Environmental Laboratory (PMEL) developer Joe Sirott created
DChart with help of other staffers so users could visualize in-situ
oceanographic or atmospheric data, a particularly challenging type of
data to render in graphical format. The software was first released
in December; an updated version was released last month. A technology
generating buzz in the Web application development community, AJAX
allows developers to build Web applications that enjoy at least some
of the functionality usually found only in desktop programs. Although
Sirott has learned about some of the limits of AJAX, the approach
nonetheless provided the needed functionality for the complex
requirements of DChart.
Former Mass. CIO Advises Partnering on ODF Projects
Carol Sliwa, ComputerWorld
Citing his experiences as the CIO for the state of Massachusetts,
Peter Quinn encouraged would-be adopters of the OpenDocument Format
(ODF) to seek out partners willing to put "skin in the game." Quinn,
who left the CIO post last month, was the keynote speaker here at a
workshop Friday on the use of the XML-based ODF in government. Quinn
had spearheaded the state IT Division's controversial initiative to
save government documents using ODF, a standard that was approved
last May by OASIS. Quinn suggested that Engelbach [Systems Safety
Manager, Virginia Beach-based Kalman & Co.] reach out to the speakers
at the event, which included officials from IBM and Sun as well as
the founder of the recently incorporated Open Document Foundation,
a nonprofit focused on improving and enabling ODF. The event speakers
were hard-pressed to offer examples of ODF implementations outside of
the state of Massachusetts. Quinn also mentioned that the
Massachusetts IT Division got a lift when the Library of Congress
stated that documents should be saved in open formats. The Open
Document Fellowship, a volunteer organization formed in September
to promote the use and development of the ODF, co-produced Friday's
workshop with Southern California Linux Expo Inc.

OpenFormula Format for Office Applications (OpenFormula)
David A. Wheeler (ed), Contribution to OASIS OpenDocument Formula SC OpenFormula is an open format for exchanging recalculated formulas
between office application implementations, particularly for
spreadsheets. OpenFormula defines the types, syntax, and semantics
for calculated formulas, including many predefined functions and
operations, so that formulas can be exchanged between applications and
produce substantively equal outputs when recalculated with equal inputs.
Both closed and open source software can implement OpenFormula.
OpenFormula is intended to be a supporting document to the Open
Document Format for Office Applications (OpenDocument) format,
particularly for defining its attributes table:formula and text:formula.
It can be used in other circumstances where a simple, easy-to-read
infix notation is desired for exchanging recalculated formulas.

Web Services Standards Investigated
Jason Stamper, Computer Business Review Online
The important standards groups and industry consortia in [the Web
Services] area are the W3C, OASIS, the WS-I and the OMG. The World
Wide Web Consortium (W3C) was founded in October 1994, largely on the
initiative of Tim Berners-Lee, the so-called inventor of the Web.
Important standards shepherded by the W3C include HTTP, SOAP and XML.
The Web Services Interoperability Organisation (WS-I) says its key
deliverables include Profiles, Sample Applications and Testing Tools.
Profiles, for example, provide implementation guidelines for how
related web services specifications should be used together for best
interoperability. To date, WS-I has finalised the Basic Profile,
Attachments Profile and Simple SOAP Binding Profile. Work on a Basic
Security Profile is underway too. OASIS, meanwhile, says that "the
work of OASIS complements that of standards bodies, focusing on making
these standards easy to adopt, and the products practical to use in
real-world, open system applications."
U.S. Grants Patent for Broad Range of Internet Rich Applications
Eric Chabrow, InformationWeek
A patent issued on Valentine's Day covers all rich-media technology
implementations, including Flash, Flex, Java, Ajax, and XAML, when the
rich-media application is accessed on any device over the Internet,
including desktops, mobile devices, set-top boxes, and video game
consoles, says inventor Neil Balthaser. Potentially tens of thousands
of businesses — not only software makers employing its business
processes but companies offering rich-media on their Websites — could
be subject to licensing fees when they use rich-media technology over
the Internet. According to the Abstract for patent 7,000,180:
"Rich-media applications are designed and created via the Internet. A
host computer system, containing processes for creating rich-media
applications, is accessed from a remote user computer system via an
Internet connection. User account information and rich-media component
specifications are uploaded via the established Internet connection
for a specific user account. Rich-media applications are created,
deleted, or modified in a user account via the established Internet
connection. Rich-media components are added to, modified in, or
deleted from scenes of a rich-media application based on information
contained in user requests. After creation, the rich-media application
is viewed or saved on the host computer system, or downloaded to the
user computer system via the established Internet connection..."
