Thats great. Please do.

I think that my caching of the file in a format that I need is fair use
and does not require permission, just like google stores a *bad*
conversion of your document in text form, or the way
I did not change it in any way, except re-hyphination. I ran ispell
over it to extract wordlists.
See also the citeceer that has an broken link to your page,
I have resubmitted the correct webpages to it for you, to try and help.
Point is that there are many caches around.
But, If you dont mind, I would like to maintain a cleaned text version
there, may I please have you permission?

I found the class hierachy in arrow, and that mini rdf document that
contained the hierarchy, very interesting as such. It at least allows
your classes and documents to be adressed as resources in an rdf
When I convert your document into rdf later on, then I can relate the
two directly, the code and the docs.

I need to review the code in more detail.

Do you want to take it down? It is just and index and I find you arrow
and graph class hierarchies interesting. When you have a better
version, I will replace it. Tunes and arrow is for me very vaporous, I
have finally found some fines I can sink my teeth into. If you dont
want them to be review and the reviews to be published, why to you have
the project linked from tunes? Please allow me to review what you have,
even if it is old.
It is very frustrating learning about tunes and arrow because I dont
understand so much of it, and there is so little code to download. Now
you are telling me that you dont even suppport your older code.... that
is very frustrating.

Yes, I am reading sowas "knowledge representation", it shows the
history of logic and all that. Point is that there is still an analogy
between the semantic web and arrow. I want to review arrow in great
detail and look for similar concepts, and document them.

useless perversion? that is quire harsh. I am going to document this
properly and find out the real connection.

I am not allergic to serious philosophy, and I am reading alot in that

So you point me to a text from heidegger, are you placing "primacy" on
his text? now you are saying that the semantic web cannot do that as
I dont know if you have read about the
various logical representations in n3, but that offers a great
here is a great comparison of sowas context graphs to the semantic web
I hope to produce such a thing for arrow.

I am looking forward to understanding that.

Funny that it is sited by a couple of people on citeseer.
I am going to review it as well.

I dont understand metatext or hll %100 yet. My feeling is that is is
expressible as an application of the semantic web. I would be suprised
by anything else.

I have yet to see the hll in some form of machine processsable form.

When I find the MetaText explanations, i will. Can you point me in the
right direction please?

I dont agree with this at all. It is igoring about 5 years of

Two wrongs dont make a right, but your comments on c, c++, c# and perl
are also rude.
Please accept my apology, I wont make any more statements like that.

Thats right, I am learning them. I see the need for a high level
language in the core of the system.

Well, the CWM and n3 notation is also a 'funky' programming language.
