There is a striking overlap in capability between the DPL extension
<http://semeb.com/dpldemo/index.php?title=Dynamic_Page_List> of
MediaWiki and the Semantic Media Wiki.  Chief among these are:

1. Both rely on metadata to add a structural foundation to an important
subset of Wiki page content
2. The structured content sits in a metadata-based data store of some
kind
3. The  data store can be queried to dynamically generate web pages

I would go so far as to say that these are [possibly by far] the MAIN
advantages of both.
This raises some important questions:

1.      What is the added value of the Semantic Media Wiki extension
when I can do so much of the same kind of thing with DPL?
2.      Does DPL give you 80% of what the semantic media wiki offers w/
20% of the effort?
3.      How can I argue to my customers that a semantic wiki is really
necessary, when we have things like DPL?
4.      What are the pros and cons and tradeoffs of each approach, when
viewed as alternatives?
5.      Is there a way to merge the extensions so there are not two
implementation of fundamentally similar functionality?

Any thoughts?
 
 
Thanks
Michael

Adding to my earlier comment...

It is interesting that you have just done this, despite numerous
arguments about why/how it could not or should not be done.  I was never
competent to evaluate those arguments from a programmer/ software
engineer's perspective, but I never bought them from a user perspective.

This raises some questions:
* how to you address those arguments? (from past forum entries)
* are there any tradeoffs from a user or developer's perspective? (which
in a sense patially validate those arguments)

Thanks
Michael

FANTASTIC!  Kudos to you for figuring out a way to do this.

Here's an idea: why not integrate the triples viewing capabilities of
Similes' Exhibit (http://simile.mit.edu/exhibit/) into the bottom of the
Semantic Media Wiki page as an alternative to the table of triples.
Possibly as a link to a separate window, or possibly embedded into the
wiki page itself (which may be much harder).

I've now created a test site for a semantic MediaWiki that lets you put
the triple (x,R,y) anywhere, not just on page x:

http://semarbtri.kgprog.com/wiki/index.php/Main_Page

The code is available:

http://semarbtri.kgprog.com/SemArbTri.txt

The syntax for a triple is "[[x::R::y]]" (or just "[[R::y]]" if you're
already on page x).

Broken things I'd like help with:

% When editing an existing page, all the semantic info vanishes.
Compare:

http://semarbtri.kgprog.com/wiki/index.php/The_Light_Fantastic
http://semarbtri.kgprog.com/wiki/index.php?title=The_Light_Fantastic&act
ion=edit

The first page has semantic info, the second doesn't. My extension does
have a "in edit mode, don't display semantic data" comment + some
supporting code, but commenting out this code doesn't help.

% When editing a new page, semantic info is visible, but unformatted:

http://semarbtri.kgprog.com/wiki/index.php?title=Wizard&action=edit

% If I try to protect against spammers by adding this to
LocalSettings.php:

$wgGroupPermissions['*']['edit'] = false;

the semantic info disappears when you're viewing new (non-existent)
pages. I've commented this setting out for now (so I can't give an
example page of where this happens), but I'd like to get this fixed.

% Minor: my code breaks the "nowiki" tag (so the main page says
"((x::R::y))" instead of "[[x::R::y]]" when giving an example)

% Minor: weird empty semantic triple at the bottom of some pages:

http://semarbtri.kgprog.com/wiki/index.php/Troll

(am I doing the MySQL SELECT wrong?)

% These are the "big" errors. There are many smaller errors + lots of
features I want to add.

Any volunteers? No CVS or anything yet (the sf.net page is not
up-to-date), but please send suggestions/code improvements.
