Software pioneer Bricklin tackles wikis
In 1979, Bricklin released VisiCalc, the first spreadsheet for personal computers. Now he's close to finishing the beta for WikiCalc, an open-source, browser-based collaboration tool that mimics the functionality of a spreadsheet while leveraging the technology of wikis, which let anyone, anywhere manipulate data across the Web.
Currently in alpha--though a stable beta version is expected by the end of February--WikiCalc is a general purpose tool developed with AJAX that runs either locally or off a server on Windows, Mac OS X, Unix or Linux. WikiCalc is designed to let people enter, store and modify data in the tabular format with which so many Excel, Lotus 1-2-3 and, yes, VisiCalc users are familiar.
"It holds a lot of promise, both because it's using the spreadsheet metaphor, which is the one thing people know for working with quantitative information and because "there's nobody better in the world to build this thing," said Ross Mayfield, CEO of collaboration software maker SocialText.
To Mayfield, WikiCalc is the answer to a problem that has been percolating for some time in the world of IT. That is, he said, that spreadsheets have traditionally been a single-user application screaming for functionality that could let multiple people edit data quickly and easily.
Of course, WikiCalc isn't the only way to use a spreadsheet on the Web.
Another product, Num Sum, lets people create Web-based, sharable spreadsheets, though not using WikiCalc's open-source model. And Microsoft's Excel by itself does not have the capability for multiple people to work inside a single spreadsheet. But this can be done using the Groove collaboration tool that Microsoft acquired last year. With Office 2007, due later this year, businesses will be able to get Groove and Excel together as part of the Enterprise Edition of Office, the highest-end bundle. Also, Windows Sharepoint Services provides wiki-like editing capabilities for spreadsheets.
In addition, JotSpot Tracker is a product in public beta that like WikiCalc allows anyone to create, publish and share custom tracking applications like spreadsheets that can integrate with other applications.
But in the world of spreadsheets, everything is going to be compared to Excel, and Bricklin's software is solving problems users have been dealing with for years.
"With (Excel), you get people playing e-mail volleyball with attachments all day long, so it's grossly inefficient," Mayfield said. "How do you track changes on a spreadsheet? What happens if you don't have just two people going back and forth, (but) have a finance department of 40 people trying to roll up numbers."
Bricklin's answer is to make it possible for anyone using WikiCalc to enter data and for anyone else to edit that data and have those edits be reflected on everyone's computers instantaneously.
"You could use it as an authoring tool without having anything more than a hosting account from your ISP," Bricklin said.
For now, not all WikiCalc features are live. For example, the ability to enter HTML into cells and do dynamic calls for information from the Web is not yet available. But Bricklin said that most, if not all, features should be ready in the beta version later this month.
As a functional spreadsheet, WikiCalc is definitively not on par with Excel, those familiar with it are quick to point out. Yet the software can handle many spreadsheet-like functions, including presenting data in the tabular format that so many are comfortable with and calculating formulas in discrete cells. And that is what could make it accessible to large numbers of people.
