How to call REQUEST.set() from within ZPT
> How do I call REQUEST.set() ?
Most uses of "REQUEST.set" can be avoided in ZPT because it has
true assignment:
tal:define="var value;
global global_var value;
...
"
If you need to communicate with objects outside the ZPT (and you
want to use "REQUEST" for this), you can use
tal:define="dummy python: request.set(....)"

Photo metadata
I've finished the cataloguing tool for my photo album and formalised how the RDF is represented for the album, each collection, associated events and event attendees and then person depictions in the images themselves.
This is done within the framework of the CC License and Work model to assign a CC license to everything aswell.
I've also set up an RSS feed of the latest catalogued pictures and then hacked Feed2JS so that it pics up the image thumbnails if they are in the feed:

Script to generate just FOAF
I've added a PHP script that generates just my FOAF, as opposed to the FOAF and blog DC.

Calendar woes
Sunbird turns out to be quite buggy and I can no longer be doing with it :(
I've had to go back to using version 1.6 of Mozilla with the 1.4 Linux install. This seems to work fine. Any later version of Mozilla and I can't get the installer to work.... Arrrrgh..

Syndicated bookmarks in Mozilla 1.0
You can now bookmark RSS feeds in Mozilla 1.0, but you need the following tags in the headers of your pages to let it know there are feeds available:
<link rel="alternate" type="application/atom+xml" title="Atom" href="http://minnesota.ncl.ac.uk/fuzzybuckets/atom.xml" />

Changes to my photo album code
I finally installed my PHP photo album on minnesota with the latest version of PHP which has GD rolled into it. When I finally got the JPEG library compiled into it though, I was getting images with only 256 colours.
I amended the code as follows and now have better image quality than I do with the app running on my iBook with a more aged PHP:
#$img_src=imagecreatefromjpeg('yoursource.jpg');
#$img_dst=imagecreatetruecolor(20,20);
#imagecopyresampled($img_dst, $img_src, 0, 0, 0, 0, 20, 20, 20, 20);
#imagejpeg($img_dst, $g_dstfile, 100);
#imagedestroy($img_dst);
$original = imagecreatefromjpeg($url);
$new = imagecreatetruecolor($width, $height);
#$new = imagecreate($width, $height);
imagecopyresampled($new, $original, 0,0,0,0, $width, $height, $size[0], $size[1]);
#imagecopyresized($new, $original, 0,0,0,0, $width, $height, $size[0], $size[1]);
Header("Content-type: image/jpeg");
if(is_null($gamma_off)){ imagegammacorrect($new, 1.0, 1.6); }
imagejpeg($new, '', 100);
#imagejpeg($new, '', 90);
imagedestroy($new);
imagedestroy($original);

I've also added CC license, DC and FOAF metadata to the scripts. See copyright.rdf.

Publishing my iCalendar files as RDF
I've been tinkering with the Python tool by Dan Connolly for converting .ics files into RDF. I've set up a series of cron jobs to grab my .ics files from the Zope server where I store them and convert them and publish them to the web server as RDF:
< http://minnesota.ncl.ac.uk/Work.rdf.xml >
< http://minnesota.ncl.ac.uk/Home.rdf.xml >
The cron jobs update the file every half an hour.

iBook blues
Went to try and do a software update again yesterday to install iTunes 4.7, but it just sat there like it had for the past four days. I decided to try and run an update from the command line and that seemed to work OK but it got to 94% complete and it stopped. I killed the process but my Finder immediately froze up. I rebooted but the Finder just hung up again with the beach ball of doom.
All the networking was still up so I ssh'd to the machine and did a top. coreservicesd was hogging 99% of the CPU cycles and each time I rebooted it just came right back up again and took over the machine.
After a night of fruitless searching and tearing out of hair, Tony M suggested I delete the /Library/Caches directory.
That seems to have fixed it. I suspect I was in some sort of Software Update induced behaviour loop :(

Libby Miller's work to convert iCalendars to RDF
Libby Miller has come up with a two stage protocol for converting iCalendars into RDF:

I've got my own iCalendars up on the Web on minnesota now:

Looking to get an RDF view of them too.

Addition to MT FOAF stuff
Added extra stuff to the MovableType metadata stuff I did yesterday. Thought it'd be nice if I could express my RSS subscriptions as foaf:subscribesTo statements. Wrote a stylesheet to convert NetNewsWire's output format OPML into FOAF RDF and then rolled it into the mt_metatada.rdf.php script I wrote yesterday.
The next step could be to build a web view of your aggregated feeds using the Magpie parser detailed earlier:

Extracting DC and FOAF metadata from the MT table structure
I've just spent the day trying to extract some decent metadata for my blogs from the vanilla MT v3.121 database tables. There's enough information there for a quite a rich Dublin Core description of the blog itself plus a very basic FOAF entry. I've augmented the FOAF entry with a very very hacky new table.
This gives an RDF description of the site with dc:creator tied to the FOAF node to produce a correct graph.
To get the raw RDF see:
<http://minnesota.ncl.ac.uk/mt_metadata.rdf.php?blog_url=http://minnesota.ncl.ac.uk/fuzzybuckets/>
Note that you pass the blog URL to the PHP script as the argument.
To render this up as HTML I then run this through an XSL stylesheet to give this:
<http://minnesota.ncl.ac.uk/render_mt_metadata.php?blog_url=http://minnesota.ncl.ac.uk/fuzzybuckets/>
