Hi,

For testing my patch for adding support for evince, the GNOME document viewer,
I try the PdfLicenseManager.

I've realised that this program doesn't tag the pdfs correctly. Possibly the
example PDF on [1], that I mentioned on a previous message on this list [2]
was tagged with this program. I was told that the licence uri must be a a
resource, not a literal.

I've written a quick and dirty patch for this [3]

Others bugs/ missing features I found are:

1) It doesn't let you to enter the web statement of your choice. It sets the
web statement with the license uri. This is a bug, FMHO and it asks loudly for
a feature ;). The web statement must be optional and be choosen by the user
(additionally the uri can be checked syntactically and even checked for
availability)

2) Only tag the with lang='x-default'. It would be nice to tag other languages
too.

3) It must let you to choose the Jurisdiction of your license

4) The interface is only in English.
