This IBM developer works article discusses what you need to know to make your Web site part of the Semantic Web. It starts with a discussion of the problems the Semantic Web tries to solve and then moves to the technologies involved, such as Resource Description Framework (RDF), Web Ontology Language (OWL), and SPARQL Protocol and RDF Query Language (SPARQL). You'll see how the Semantic Web is layered on top of the existing Web. It then covers some issues that you want to know about when you plan a new Web site and also gives specific examples of how to use technologies like RDFa and Microformats to enable your existing Web site to become a part of the Semantic Web.

ShiftSpace is an open source layer above any website.

It seeks to expand the creative possibilities currently provided through the web. ShiftSpace provides tools for artists, designers, architects, activists, developers, students, researchers, and hobbyists to create online contexts built in and on top of websites.

A short history of tagging

Tagging 1.0

• just tags !
  

Tagging 2.0

• geo tags ?
  

Tagging 3.0

• triple tags or machine tags !
  

Yahoo! flickr & Yahoo! upcoming have now enabled triple tagging or machine tagging !

This allow your flickr photos to automatically appear on the upcoming event they were taken at if you use the correct triple tag or machine tag

For example if you want your Brighton Festival flickr photos to appear in the upcoming event just tag them with the tag upcoming:event=188114

Machine tags are sometimes called triple tags because they consist of three parts:

• namespace i.e. upcoming
• predicate i.e. event
• value i.e. value
  

Now there's a single sign-on login process for Flickr, Upcoming & Yahoo !

• OSDE.INFO on Flickr
• OSDE.INFO on Upcoming
• OSDE.INFO on Yahoo 360
  

And I imagine del.icio.us can't be far away !

• OSDE.INFO on del.icio.us
  

Web 3.0 begins today !

How to create your own Web 3.0 Social Semantic Network (SSN) in minutes:

1. Choose a Web 2.0 or Web 3.0 social networking site such as VOX or flickr
2. Enter a "keyword" or "tagword" into the group search
3. Join group(s) (that you like the look of)
4. Favoritise photo(s) in the groups (that you like the look of)
5. Make favorite photo poster a "neighbour/friend"
6. Then look at their groups (and "neighbours/friends")
7. REPEAT steps 3-6 as necessary
   

In no time at all you'll have a Social Semantic Network of over 300 people & "groups" !

For example http://flickr.com/people/fsse-info/

I just installed the new del.icio.us firefox addon

1. It KILLED performance of my PC because it "syncs" my 3000 online bookmarks with the local PC
2. I can't see suggested tags any more since it displays a list of 200 of my network contacts first
   
3. ... I was just about to uninstall it when ...
   
4. It freaked me out by displaying bookmarks (that i created at work yesterday) on the new del.icio.us toolbar of my home PC

For an instant I thought I was in my office at 6am on Saturday morning !

So BEWARE I expect it will display your home bookmarks on your work PC if you install the new del.icio.us on your work PC !

This weekend I set out to rebuild Xen server as an Edubuntu & VMware Server and install rPath SugarCRM, Joomla, AsteriskNOW, Tomcat  & W2K virtual machines. I also needed to install Xubuntu on a couple of IBM ThinkPads.

Installed Edubuntu and discovered that 119M is being used by SchoolTools so put remove instructions on Ubuntu wiki (BLOG#1), discover SchoolTools is missing from Ubuntu wiki (BLOG#2A) and Swik (BLOG#2B).

Fiddle with VMware services then get strange error when trying to start a virtual machine ! Remember I forgot to turn them back on so update VMware forum (BLOG#3).

Download rPath AsteriskNOW and Joomla software appliances. Joomla startup screen up has some great MySql security and MySql benchmarking tips so update fsse.info (BLOG#4) and cross ref back to VOX (BLOG#5). Take some AsteriskNOW screenshots and post to VOX (BLOG#5) and cross ref to voippix.org (BLOG#6)

OpenSolaris fails to boot after moving 2.5" HD from a PIII 256M IBM Thinkpad to one with only 128M. Error message says something about check "$ svcs -xv" ! Maybe that's the Solaris equivalent of Red Hat "$ services" better remember that (BLOG#7)

Decide to replace OpenSolaris with Xubuntu Alternative 6.06.01 which does work on 128M, so download ISO. Forgetton how to burn CDs on Ubuntu so "$ aptitude search burn". What's this "cpuburn" thing ? It sounds like it could be useful in the future ! (BLOG#8)

Read my del.icio.us network RSS feed ! What's this teachers.yahoo.com thing ? (BLOG#9), is there a VOX Teachers group ? Yes ! Join it ! Cross ref Yahoo Teachers to VOX Teachers (BLOG#10)

[The never ending chain of semantic links seems to be infinite]

Education hmmm ! Teachers would like Kalcium wouldn't they ? Kalcium isn't on Swik ! (BLOG#11A), cross ref to VOX (BLOG#11B). Actually Kalcium is also great edutainment ! Is there a VOX Edutainment group ? There is now (BLOG#11C).

[I still maintain that groups == tags]

Xubuntu Alt is now burn't so it's time to attack those two IBM ThinkPads. The IBM BIOS seems to be out of date ! But oh no the BIOS updater is an EXE (at least it's an EXE that creates floppies) ! Can I use WINE (which I've never tried) or do I need to build a W2K virtual machine from scratch (last done over four years ago)

Decide to go the known route and build W2K and then flash the BIOS (BLOG#12) but I'll blog the process so I'll remember in another four years (BLOG#13). There must be some other valid excuses to use W2K ? I can only think of four ! (BLOG#14)

See a del.icio.us link about another user saving £1000's by using Amazon EC2 thats worth a blog (BLOG#15) and maybe a VOX group (BLOG#16)

FINALLY blog this (BLOG#17)

Not bad for a weekends work ! I need a break now !

Went to London's http://www.socialmediaclub.com/. Tonight's topic was "Music & Sound".

If you want to hear what you missed you should be able to download a netcast/podcast from their blog http://smclondon.ning.com/ or from their wiki http://socialmediaclub.pbwiki.com/London.

I'm looking forward to going again.

Flickcurl is a C library for calling the Flickr Web service API from Redland RDF.

It handles the API signing, token management, and parameter encoding and decoding, resulting in C functions for the Web services APIs.
