Congratulations on getting this all up and running. It would be cool if you put your
installation (-credentials ) on github with all this info a readme, in case anyone wanted
to follow your footsteps in the future.

After a couple of months of trial and error and with the kind help of the metavid /
mediawiki community, I have successfuly reached a properly working installation comprising
of:

Semantic Forms Inputs (Version 0.4.1)Additional input types for Semantic Forms
Sanyam Goyal, Yaron Koren and Stephan Gambke

The latest extensions added were :

-ExternalData 0.6.1
Minor code changes were required since it failed to download any data from external urls.

-Semantic Mediawiki version 1.4.2 (required by Semantic Forms 2.2.1 and Semanti Forms
Inputs 0.4.1)
This required quite some code patching which was performed based on the patch files as
provided by George Chriss at
https://labsconsole.wikimedia.org/wiki/Nova_Resource:Metavidwiki/openmeetin…
I had to apply the patches by hand since my code was a bit different and the patches
failed using the patch command.

-Semantic Forms Inputs Version 0.4.1 &
-Semantic Forms 2.2.1 to provide extra input type fields, used for entering various data
using a more user-friendly interface.

A strange behavior was experienced at first, since when adding a new Form (by using the
special Create new class page) resulted in creating a Stream:pagename instead of a
Form:pagename. Only the Form creation had this issue, Templates, properties and categories
were properly created by the same special page.

I believe that the way I fixed it was adding to LocalSettings.php the following
variables:

//set up namespace
$smwgNamespaceIndex=100;

//set metavid namespace to smw namespace + 10 Initially it was +6
$mvNamespaceIndex=$smwgNamespaceIndex + 10;

//add the new custom namespace index for Form and Form_talk
define("NS_FORM", 500);
define("NS_FORM_TALK", 501);

$wgExtraNamespaces[NS_FORM] = "Form";
$wgExtraNamespaces[NS_FORM_TALK] = "Form_talk";

Unfortunately, I'm not fully sure that the above changes/additions actually fixed the
Form creation problem since I got impatient and performed a couple of changes at once. I
will test to see which change actually fixed the issue.

The current open issue I'm working on is with the thumbnail creation of videos using
ffmpeg. In George's patches 'thumbnailer' is used and I can't find this
s/w so I will need to substitute it with ffmpeg thumbnailer .

Ioannis
