[MOD] Dublin Core Metadata integration

jojaba · 2010-01-18 09:08:09

[IMPORTANT: This Mod has been released in the Resource pages of this site: http://fluxbb.org/resources/mods/dc-metadata/]

What is Dublin Core Metadata ?
This metadata comes from DCMI:

DCMI wrote:

The Dublin Core Metadata Initiative, or "DCMI", is an open organization engaged in the development of interoperable metadata standards that support a broad range of purposes and business models. DCMI's activities include work on architecture and modeling, discussions and collaborative work in DCMI Communities and DCMI Task Groups, annual conferences and workshops, standards liaison, and educational efforts to promote widespread acceptance of metadata standards and practices.

See the Metadata Basics to learn more about them.
I give you other resources to have a summary on that subject:

Wikipedia article
OpenWeb article (Sorry, in French, but this article helps me a lot to understand, a translation made by Google )

An here's the modification
The following modifications must be done in the header.php file (line 83)

Add after:

<link rel="stylesheet" type="text/css" href="style/<?php echo $pun_user['style'].'.css' ?>" />

This code:

Some points to check and to know before adding this mod:

The language folder must be well syntaxed (see the ConvertLangNameInIsocode () function)
The Dublin Core Metadata won't be added to the administration pages

Note: This Mod is the result of the discussions on the Dublin Core integration topic

Maybe you should add a description to the post for those who don't know what this is about...

I wonder if I could make a plugin with that Mod...
Before beginning with the work, I would like to have some advice about what I will try to do. Here what I already think about:

Create a plugin page called for instance "AP_Dublin_Core_metadata.php" in wich I will add the core of the plugin
Create a folder (named for instance "dublin_core_metadata" that should contain eventually needed files (such as language files, storing data files, ...

I would like to add dynamically (using php language) the lines into the header.php file by clicking on a button located on the core file (AP_Dublin_Core_metadata.php)
Do you think this could be doable?

Just one question : where should I find the available function for the plugins ?

Thanks in advance

Well I've done it!
Dowload link removed because obsolete
You just have to send the file and the folder in the *zip file to your Plugins folder, visit the Plugin page to understand what it can do... (you have to have Admin level!)
Thanks for feedback

Nicely done.

I'll look into it when Flux is stable.

Thanks !
I'm not sure the way I did it is the best way. I'm waiting for technical feedback (code optimisation and fixing bugs) and also feature requests...

Well, the stable version of FluxBB is out, did you test it?
I would like to here if this way to install modifications is a good way

jojaba · 2010-09-01 07:54:55

I'm proud to announce that DC Metadata Mod has been approved by the FluxBB devs and released:

I think, it's an evil plugin
Activated, it makes the link "Moderate forum" dead with "Unable to fetch post info" ...
Deactivating it -> Everything is ok ..

Thanks for that feedback
I will look into it as soon as possible, stay tuned !

Fixed the problem and added to the new package German translation (that maybe has to be improved ) :
http://fluxbb.org/resources/mods/dc-met … eases/1.0/
If you want to fix it immediatly, just do the following in the /plugins/dcm/dcm.php file :
add »

//Getting the forum or topic id
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;

before »

Danke für dein Feedback

New release that should fix the problems and adds a subject metadata for each specific page : http://fluxbb.org/resources/mods/dc-met … eases/1.0/

jojaba · 2011-01-13 06:55:11

New release: http://fluxbb.org/resources/mods/dc-met … eases/1.1/

jojaba · 2011-01-25 10:35:27

FluxbB 1.4.3 released. I tested the update procedure, DC Metadata just worked fine. You just have to go to the admin page and click on the Install button to reenable the Mod ;

Bloody · 2011-03-11 14:42:49

Very well done your DC Plugin.
Really very simple to install it as your Avatar Choice plugin.

Thanks a lot for sharing.

I've tried to use fbb 1.4.4 and version 1.1 of this plugin with the same result .

I've tried to use fbb 1.4.4 and version 1.1 of this plugin with the same result .

Really sorry, but yes, this problem still occurs also for me. One more thing to put on my todo list
Thanks for that feedback.

The last Dublin Core Metadata mod works with FluxBB 1.4.6.
If you already installed this mod version, and you have upgarded to FluxBB 1.4.6, you just have to visit the admin page and click on the install button.
