Re: [SMW-devel] Inline Editing Functionality by using RDFa

[Yaron K. <ya...@gm...>]

Hi Benedikt,

One big problem that exists with trying to edit properties inline is that
there isn't always a direct relationship between property values and values
on the page. A property value can be the result of any sort of computation -
and even when there appears to be a 1:1 correspondence, it can be the result
of a tricky setup like:

{{#if:{{{field1|}} | [[myproperty::{{{field1|}}}]] |
[[myproperty::{{{field2|}}}]] }}

I don't know of any solution to this problem (figuring out which property
values are directly editable); and I'm not 100% sure that there is a
solution that will always work.

On the other hand, I believe there are at least two extensions that already
try to do something like this (though not via RDFa), so maybe your job is
easier: The first is SMWWriter:

http://semantic-mediawiki.org/wiki/Help:SMWWriter

The second is an extension that I saw demo'ed somewhere, I think written by
Vulcan, in which you can edit values via the SMW factbox. Although maybe
they just described it, and didn't actually demo it - I can't remember now.
