TikiWiki
As a TikiWiki developer I have committed some to the current stable branch-1-9 and also was asked to be release manager for 1.9.2. Though I'm still active at fixings bugs, my main interest goes towards current CVS HEAD, the development version. There are some really decent developments checked in, that provide endless possibilities. This is e.g. the Freetag Folksonomy Tagging, but also the center-column-dependent modules(notice, how the hCard module disappears, when you go to contact).
Being a man - but not programming my own device drivers - I decided to extreme dog-food my developments to myself, right here on this site. All this is mostly centered around Web2.0 technologies and concepts.
Social Bookmarking
Social Bookmarking are called services like del.icio.us, Ma.gnolia.com or otavo. del.icio.us was probably the one, that started all the hype about social web services, sharing, web2.0, consumer auto-generated SOA and the like.
I implemented tagging of TikiWiki user bookmarks and coded a public frontend to them. This was developed on http://dev.amette.eu, but is currently in migration planning for roll-out to http://amette.eu at http://migrate.amette.eu
# cd <MYTIKIDIR> # wget -R "index*" -X "$REPO/_darcs" -r -np -N -nH --cut-dirs=2 http://darcs.amette.eu/social_bookmarkin-patchset # mysql -pf <MYDB> < db/tiki_1.9to1.10.sql
AJAX
Modern interfaces need to be responsive - and possibilities with AJAX are decent!
Currently TikiWiki development is not really progressing on the integration of AJAX technology since the move from cpaint to xajax. The last running example was this pagination code, implemented for freetag-browsing. It hangs on the last page of a listing with the Loading-message - so prefer big tags! ;) I'll try to hunt this one down still though. If you want to patch your current TikiWiki HEAD to this mostly working state, then..
# cd <MYTIKIDIR> # wget -R "index*" -X "$REPO/_darcs" -r -np -N -nH --cut-dirs=2 http://darcs.amette.eu/freetag_ajax-patchset/ # mysql -pf <MYDB> < db/tiki_1.9to1.10.sql
Folksonomy Tagging
Metadata-craze and Folksonomy Tagging were the cornerstones of this development. Folksonomy tagging is implemented with Gordon Luk's FreeTag, see http://dev.amette.eu/tags for a running example of the AJAXified tag-browsing interface in very early alpha.
