This is great, thanks for sharing :)

Brief notes to report some success with these tools in a Linux/Debian 
environment using the Mono C# implementation (whichever version is 
currently packaged in Debian Unstable distribution).

unpacking the binary and src distrib, I can run the binary as 

danbri@fireball:~/tmp/mono/ical$ mono ical2rdf.exe testcases/birthdays.ics

...and it spits out RDF.

As for compiling... I promise it worked yesterday, but then I did 
an 'apt-get upgrade' and perhaps Mono got updated. The following 
command in the source dir should build a .exe:

	 mcs -r System.Web *.cs

Right now I'm seeing errors (unrelated to the cal stuff I think), 

** (/usr/share/dotnet/bin/mcs.exe:21679): WARNING **: Missing method

 Emitter.cs(461) error CS8025: Parsing error

...but I guess that's why they call this version of Debian 'Unstable'.

I'm pretty sure that folk with a working Mono setup should be able 
to use this easily. It built perfectly last night!

thanks again,
