Are there recommendation for max dc:descriptions length?

Hi,

I just noticed that a epub with a metadata dc:description entry of
Number of paragraphs: 1 (so no line break)
Number of words: 950
Number of letters and digits: 3.696
Number of characters: 4.296

causes my Sony PRS-650 to take about 20 seconds to open this particular file.

Without the ds:description meta-data in contents.opf, the very same file opens up in less then 2 seconds.

So are there any recommendation for max dc:description length?
Or is this an issue with Sonys implementation of ADE?

There's no recommendation on that, that I know of. And I'd say any reader behaving like that is gravely buggy... especially when it doesn't use the dc:description at all, anyway.

Thanks, Jellby!

To my ?surprise? the older Sony PRS-505 handles the same file with no hitch.
