ABSTRACT
Web-based replacements for spreadsheets and simple forms
By Dave Raggett, W3C Fellow and Principal Researcher at Volantis Systems.
The ability to collect data from users and to submit it to servers has become a very important part of the Web. Forms are often supplemented by Web page scripts that enable the data to be checked as the user is filling out the form and before sending it to the server. These scripts can get quite complicated to develop and to maintain, making it interesting to explore ideas for replacing such scripts by equivalent declarative approaches.
XForms-Tiny is an incremental extension of HTML4 forms that can be deployed on today’s Web browsers using an open source cross-browser JavaScript library that works on Internet Explorer 6 and 7, Firefox 1.5 and 2, Opera 9, Konqueror 3.5, and Safari, When delivered via HTTP as a compressed file, the download size is only 6 Kilo Bytes.
XForms-Tiny provides authors with the means to use simple JavaScript expressions for validating field values and spreadsheet-like formulae for computed fields, but also the means to describe repeating groups of fields, e.g. for line items in a purchase order. XForms-Tiny further provides for suppression of irrelevant parts of forms and context dependent control over which fields must be filled out. All this is possible without the page author needing to write any lines of client-side script.
This talk will present XForms-Tiny and place it in the context of related work (Web Forms 2.0, XForms-Basic, and XForms full) as well as the challenges for dealing with the small displays on mobile devices.
You will also learn about new approaches for browser-based editors that avoid the pitfalls of designMode and which are paving the way for a replacement for spreadsheets, browser-based editing of slide presentations and much more.
If people are interested and there is time available, I could also give a brief summary of the impending W3C Ubiquitous Web Applications working group that applies markup and eventing to simplify the development of distributed applications across a wide variety of network appliances including desktop computers, office equipment, home media appliances, mobile devices (phones), physical sensors and effectors.

ABSTRACT
Stem cell technology and the debate surrounding it has generated a great deal of excitement and controversy in recent years. The field is surrounded by misconceptions, hype and yet very significant potential. In this talk we’ll cover: defining what are stem cells really and where do they come from… the differences between embryonic stem cells and ‘adult stem cells’ (i.e. derived from our own bone marrow, fat, umbilical cord blood, placentas and even our kids teeth) and emerging technologies to utilize these cells in powerful and novel ways. We’ll cover current clinical uses of stem cells, ongoing clinical trials in regenerative medicine (i.e. using marrow derived cells to treat heart attacks, vascular disease, stroke and even diabetes), upcoming trials utilizing embryonic stem cells, and some of the likely near term and future applications as well as challenges remaining in order for this field to reach its full potential.
Speaker: Daniel Kraft, MD
Dr. Daniel Kraft will provide an overview of stem cell biology, including embryonic and adult stem cells, their current use in the clinic, and ongoing developments in the push for therapeutic applications utilizing stem cells for use in biomedicine and the evolving field of tissue engineering and regenerative medicine. This talk will include a summary of major stem cell technologies, and related bioengineering and devices.
Daniel Kraft, MD is a physician-scientist at Stanford University Medical School, where his clinical focus is hematology/oncology and stem cell transplantation. He is also on clinical faculty at UCSF on the bone marrow transplant service and is a lecturer for the Stanford Bioengineering program. Daniel graduated cum laude from Brown University, and received his medical degree from Stanford University, where he was also a Howard Hughes Research Fellow, and graduated with honors in research. He went on to complete a combined residency at Harvard in Internal Medicine and Pediatrics at the Massachusetts General Hospital and Boston Children’s Hospital, followed by fellowships in hematology/oncology and bone marrow transplantation at Stanford. He is currently funded by the NIH and conducting research in the laboratory of Irv Weissman. Read the rest of this entry »
