Forgive me if you don't find this
funny.
We at the World Wide Web Rebellion
(W3R) are providing standards to be used that are easy to "code", we don't
care
about functionality, we don't care
about users, we want programmers to be happy and enjoy some spare
time.
With this in mind we've produced a
lot of specifications that may replace XML in a near future (depending
on
difficult to evaluate rebellion
factors)
Our meta-language is called "cadorch"
and is a lot easier than XML.
The World Wide Web Rebellion
presents:
Available documents by the
W3R
- Cadorch 1.0 syntax
specification.
- COM level 1.
- SAC
- XTC
- Querydorch
- Cadorch
Schema
--------------------------------------------------------------------------------------------
Cadorch
1.0 Syntax specification.
W3R recommendation.
A well-formed cadorch message must
follow the following rules:
1. A cadorch 1.0 document is an
ordered sequence of "fields".
2. Fields must be sepparated by the | "pipe"
character.
3. A field may contain any ASCII charater except the |
"pipe"
4. If you want to include a pipe in a field you have a problem.
5.
Parsers MUST ensure that a cadorch message is well-formed.
Since
any ASCII string may be a well-formed cadorch message
this is
usually very easy to do.
6. The first field is numbered 0, the second 1 and
so on.
Example:
Peter|5|62732|yes|no
As you can see a cadorch document
cannot be easily undesrtood by
humans nor machines but is quite easy to parse
which is good for
programmers.
Example 2:
John Smith|24|Student
End of the document.
Pseudocode to validate
well-formdeness:
validate_cadorch(msg) {
return true;
}
--------------------------------------------------------------------------------------------
COM
level 1 (Cadorch Object Model)
W3R recommendation.
This document describes the Cadorch
1.0 object model.
A cadorch 1.0 message can be
represented as an array of fields,
for example:
John Smith|24|Student
Can be represented as:
[John smith] - [24] -
[Student]
The following classes are defined in
the Cadorch 1.0 Object Model:
Message
Field
And the methods are:
Message:
getField(index) returns field indicated by the
index.
Field
getContent() returns
field content
Example:
message = new Message("John
Smith|24|Student");
field2 = message->getField(2);
data =
"field2->getContent();
--------------------------------------------------------------------------------------------
SAC
(Simple API for Cadorch)
SAC describes an API that can be used
to parse Cardorch 1.0 messages
as defined in the W3D
specification.
As the parser process a cadorch
message events must be generated, events
can be intercepted by callback
functions defined by the user.
Only one event is defined:
field
The field event should call a field
handler passing the field data to
the handler.
Pseudocode example of a SAC parser in
action:
foo(field_data) {
// do
something
}
parser = new
Parser(msg)
parser->set_field_handler(foo)
parser->parse()
--------------------------------------------------------------------------------------------
XTC
(pronounced [extasees])
eXtensible Transformations for Cadorch.
W3R
recommendation.
This document describes the XTC
language, a template based language designed to
transform Cadorch messages in
any representation.
Everything is a valid XTC stylesheet,
in "everything" you can embedd Cadorch
fields using the syntax c[0],c[1]
etc.
Example:
My name is: c[0]
My age is :
c[1]
Can be used to transform the
following Cadorch message:
John|25
Into:
My name is: John
My age is :
25
XTC processors must always replace
c[n] occurrences by the corresponding field value in
the Cadorch
message.
If you want to output a literal c[x]
string you can't.
If c[n] does not exist in the message it is replaced by
nothing.
--------------------------------------------------------------------------------------------
Querydorch
A
query language for Cadorch.
W3R recommendation.
This document describes Querydorch a
query language for Cadorch 1.0 messages.
A query is expressed as:
c[n]
Where n is a number indicatig a field
number.
The query returns the information contained in the
field.
Example:
Hi|hello world
c[1] returns "hello world" while c[0]
returns "Hi"
--------------------------------------------------------------------------------------------
Cadorch
Schema
A Schema language for Cadorch messages.
A W3R
working-draft.
A Cadorch Schema definition (csd) is
a file describing the semantics of
a cadorch message field.
A csd file has the following
format:
field_name
position type
field_name
position type
....
Example:
name 0 string
age 1
integer
Datatypes:
string,integer
