I have a prototype of my metadata proposal implemented, and have run into a

My (erroneous) assumption was that by implementing preSave and preTranslate
filters I could encode the metadata without the user knowing. This is
certainly true for the scenario where the user enters some metadata, saves
the page, and views it. Unfortunately, the preTranslate filter is not called
prior to an edit so when the user edits a page after saving it they will see
the encoded metadata. I can write the encoding logic (in the preSave) filter
to handle this situation, but it is still messy in that the user is now
aware of my 'fiddling' behind the scenes.
I don't suppose there is some other mechanism that would allow me to decode
prior to an edit? Could I extend WikiEngine or PageManager to behave the way
I want, and insert my own instance into the server?
Bob,
It sounds like you are trying to retrofit a record/page metadata
scheme on top of a very difficult edifice. As someone who's played
a lot with plugins and filters they work very well for what they
were intended for, but it's difficult to create certain kinds of
functionality. I wrote a plugin that permitted a declaration of a
name-value pair, then also wrote that as a page-level metadata,
and it works passably, but with 3.0 coming up I've given up on it.
I've had a basic task of reformulating the metadata handling of
JSPWiki 3.0 since by that time our entire backend will be JSR-170
compliant. Janne has worked up a prototype that I've not had much
of a chance to test. I don't have any time right now to go through
the archives but you can search on priha, JSR-170, JackRabbit and/or
metadata and you should be able to find stuff.
I think extending one of the larger objects in the JSPWiki pantheon
is really asking for trouble, if you wanted any advice on that matter...
