Fwd: Publication specific page meta-data
Didn't get any interest in this on lenya-user, wondering if dev is a more
appropriate place to discuss it?

Hi
I'd like to add some custom meta data to my pages created in lenya. My idea
is to create a library of advertisements or some other small html element
which i then associate with a specific page via the metadata. The
advertisement is the included into the page via the aggregating pipeline
which adds navigation etc to the page. Then the xslt puts the advertisement
on the right place on the page.
Another idea I have is to create an image gallery component for a page. Eg,
cms text/images on the left, then on the right have images which are declared
as assets but with an additional tag which says they are part of an image
gallery.
I'd like to make my own namespace for the metadata, eg custom:ad, i've read
through the dublincore java classes, pagenvelope and document classes and I
figure i'll need to implement my own custom class in a similar manner to
these.
Anyone done anything similar and can share their experience?
Michael

I'd rather add the elements outside the <head> section, e.g.
<html>
<lenya:meta> ... </lenya:meta>
<foo:meta>
<foo:keywords> ... </foo:keywords>
</foo:meta>
<head> ...
</html>
You have to add the declarations to the Relax NG.
I'm not sure about Kupu, but if you add the appropriate CSS you
can edit your meta data with BXE.

Yes.

That would probably require massive changes to the codebase.
I wouldn't recommend it, since you don't get much benefit from
having it in the Lenya core.

I was going to make a custom usecase anyway, so that is no problem.
Are you saying that if I make a doctype that includes the xhtml doctype, then
I can declare additional data in the <head>...</head> portion of the
document, and BXE/Kupu won't throw that away when used to edit the content of
the document?
Then I can edit those addition head contents with my own usecase right?
Would it be possible to backport the custom metadata to 1.2? I require the
stability of 1.2 for my application.

No, the user list is fine.
I guess the problem is that the anwer is "That's not possible with 1.2"
and nobody wanted to admit this :)
1.4 supports custom meta data, in 1.2 you'll have to add them to your
doctype and edit them through a custom usecase or through one of the editors
(BXE or Forms Editor).
