Last week was the first PDF 2.0 interop event in Cambridge, UK, hosted by Global Graphics on behalf of the PDF Association. The interop was an opportunity for developers from various companies working on their support for PDF 2.0 to get together and share sample files, and to process them in their own solutions. If a sample file from one vendor isn’t read correctly by a product from another vendor the developers can then figure out why, and fix either the creation tool or the consumer, or even both, depending on the exact reason for that failure.
When we make our own PDF sample files to test the Harlequin RIP there’s always a risk that the developer making the file and the developer writing the code to consume it will make the same assumptions or misread the specification in the same way. That makes testing files created by another vendor invaluable, because it validates all of those assumptions and possible misinterpretations as well.
It’s pretty early in the PDF 2.0 process (the standard itself will probably be published later this month), which means that some vendors are not yet far enough through their own development cycles to get involved yet. But that actually makes this kind of event even more valuable for those who participate because there are no currently shipping products out there that we could just buy and make sample files with. And the last thing that any of us want to do as vendors is to find out about incompatibilities after our products are shipped and in our customers’ hands.
I can tell you that our testing and discussions at the interop in Cambridge were extremely useful in finding a few issues that our internal testing had not identified. We’re busy correcting those, and will be taking updated software to the next interop, in Boston, MA on June 12th and 13th.
If you’re a Harlequin OEM you can also get access to our PDF 2.0 preview code to test against your own or other partners’ products; just drop me a line. If you’re using Harlequin in production I’m afraid you’ll have to wait until we release our next major version!
If you’re a software vendor with products that consume or create PDF and you’re already working on your PDF 2.0 support I’d heartily recommend registering for the June interop. I don’t know of any more efficient way to identify defects in your implementation so you can fix them before your customers even see them.

And if you’re a PDF software vendor and you’re not working on PDF 2.0 yet … time to start your planning!
