the myVocs demo went well and along with Jim's work, seems to make a very nice system environment. struck again how clearly bogger.com, technocati's and del.icio.us have the potential to become the major new applications of you desktop with these technologies. amazing to see the type of system experience that can be defined with so many interfaces available. interesting trend graphs to namespace creation and management.

am working on getting the demo in an on-line followable version and will add a link when I ha

have made slow plodding progress on the myvocs demo. managed to avoid
getting sidetracked with a sympa5.1 installed after checking for the rss
feature in sympa5.0 and seeing that it works. had to get a better
understanding of rss and how live bookmarks are created in firefox.
thought sympa had a problem with rss content type at first but it was just
a problem with the rss.ttl, it didn't have a closing brace on one of the
elements. Also updated template to just show listname and not have a
newline in front of the title since firefox seems to interpret all
whitespace literly in the title element. it seems firefox only "sees" the

!UPDATE: May 17, 2006
Two recent presentations have been given that provide an overview of myVocs and the scope of the technology and project. The first as at the [Spring 2006 Interent2 Member Meeting|http://grid.ncsa.uiuc.edu/presentations/i2mm-myvocs-gridshib-april06.ppt] in April and discussed our collaboration with the GridShib project and the second was given at the [TERENA 2006 conference in May|http://www.terena.nl/events/tnc2006/programme/presentations/show.php?pres_id=206]. This latter presentation is a good overview of the goals and architecture of myVocs. More updates to come.

!Pre-requisites

The first part of the install was mainly influenced by the need to install
ruby and rails, the platform for yubnub. This was fairly painless on fc3
after some poking around and getting familiar with ruby.

Did a subversion co of:

http://svn.yubnub.org/svn/yubnub

Installed ruby with up2date on fc3 and installed the "gem" tool that seems
to be the equiv of cpan and pear. During my install I also found that I
was missing irb and rdoc which are two ruby tools. After some more poking
I realized I could install them with up2date and that cleared up the ruby

answers to technical issues. we'll try to bring clarity to the developer
by focusing on the issues that are within our control and not getting
distracted with organizational issues. it's not that this issues are
unimportant in a deploy it's just that we want to look at the technology
and identify what is possible. it will be easiest to do this by
controlling the namespace of attributes in a way that is common in
homogenous system environments.

while i'm thinking about this. it's best not to use a javascript post to
enable webiso on a legacy app. this makes it hard to go directly to
specific urls in the legacy app. for webiso/vosp to work well it is best
to present a uniform namespace to the world and simply have restricted
areas in the namespace trigger the permissions checks. while the "touch
this java script page to generate a post to log the user in" works ok it
doesn't supply this type of namespace. all access to that subtree will
need to be through that javascript login post. this will prevent direct

Here's a site (http://dbacl.sourceforge.net/spam_chess-1.html) where someone uses baysian filters to play check (good/ham moves versus bad/spam) moves. This approach might help realize my idea to improve folksonomy with basian filtering (http://lab.ac.uab.edu/node/edit/1245). It really makes sense since what having many people tag the same data does is pretty much the same as way a bays filter automates. worth looking into.

got yubnub working today. nice tool. will post my notes soon.

reviewed the gridsphere install with cyy and discussed the customizations
needed to get it working like our current ogce interface. also reviewed
uportal and sakai to see if they might offer better initial integration
with webiso and (potentially) shib. Seems uportal can do CAS but that's
not what we have here. Besides, I feel like CAS is confusing authn with
authz. I'd rather have a more flexible authz framework like shib than the
authn plus 1 type of authz that CAS offers. Also uPortal is pretty heavy
weight, being targeted at univ. portal solutions. We wouldn't used many
