OpenDocument (ODF) Acid Test Proof of Concept

Morning all,

I’ve just put the finishing touches on the first
proof-of-concept Acid Test for OpenDocument Format (ODF) which I hope
will become a useful tool for encouraging and testing interoperability.
The tests themselves (148 of them in the 14×14 grid following the Web Standards Project‘s Acid2 test) still need development, as explained below, but the framework is in place.

You can read more about it at and in the post to the OASISODF Implementation, Interoperability and Conformance (IIC) Technical Committee Formation‘ mailing list below. You’re also encouraged to get involved if you have something to offer to the standards process.

Here’s a sneak preview:

And here’s the post:

Subject: ODF Acid Test – Proof of Concept

Morning all,

a view to starting this week afresh I have been busy over the weekend
preparing the first proof of concept ODF Acid Test for the spreadsheet
component. The results are surprisingly impressive, thanks in no small
part to conditional styles
which allow me to set the cell colour depending on whether tests pass
(1+1=2) or fail (1+1=3). For more information about the test
methodology, samples, and the files themselves, refer to

is not to be confused with an interop panacea (there is no such thing),
but it can be used to focus attention where it is most needed (provided
the attention is not too focused!). It also allows users to get on board the interop bandwagon and has proven a potent incentive for the browser vendors. Kudos to Google’s Ian Hickson and the rest of the Web Sandards Project for their pioneering efforts in this area.

Kind regards,
