#### Describing Blogs Mathematically

```Hi all,

This is my first post, so excuse me if I am a bit green.

I was recently asked to explain blogs mathematically to someone... I am
struggling a bit with the task and was hoping to get some feedback.
Here is an attempt at how I would describe blogs with pseudo-formal
notation (Wouldn't know how to do it formally).  It's rather messy, but
it is a start...

B is the set of all blogs
b is a blog
E is the set of all entries
e is an entry
C is the set of all comments
c is a comment
A is the set of all authors
a is an author
R is the set of all blog aggregators
r is a blog aggregator

B = { b0, b1, ... , bn } - The BlogoSphere is the unordered set of all
blogs
bx = { ex,0, ex,1, ..., ex,n} - A blog bx is the set of all its
entries, where ex,y is not older chronologically to ex,y+1
For each entry ex,y there is a set of comments cx,y = { cx,y,0, cx,y,1,
...., cx,y,n }, where cx,y,z is not older chronologically to cx,y,z+1
For some comment cx,y,z = ba,b (some comments are blog entries via
track backs)
Each blog bx has at least one author aa in A who can create entries
Each entry ex,y has exactly one author aa in A who is the author
Each blog aggregator r is a fixed set of blogs {bx, by, ..., bz}

Typically, a blog bx displays entries ex,y on a  are displayed in
reverse chronological order: { ex,n, ex,n-1, ..., ex,0 }

Typically, a blog bx has an individual view where comments cx,y,z are
displayed with their bx,y in chronological order: {cx,y,0, cx,y,1, ...,
cx,y,n}

Typically a blog aggregrator r displays the most recent entries from it
set of blog.

Does any of this make sense?  Any references I could read to brush up
on my notation?

Joe

Matlab and Mathematical theory of languages
Dear All, I'm writing to this list since am looking for a cooperation. I'm working about the development of a mathematical theory of languages. It defines a language as a set of elements which can be combined or associated (see the PS for an example). I'd like to cooperate with a computer scientist in order to define a Matlab package useful to create and to analyse a catalog of mathematical languages. This package should be placed in the public domain, freely accessible to anyone who might be interested. In the continuation of the message I send a sample function to include i...
