Subject: Re: New URC Specification is ready....
Message-Id: <773487002.23785.0-faugeres.inria.fr*@MHS>
A few unordered comments/questions about the draft (and sorry but I really
feel unhappy with the global specification)
-- PAP
General comments:
- it is an error to merge in a single document encoding and use
- the encoding part though not perfect can be refined and should
remain the core of this document
- the use part must be moved to sone distinct document or at least should
be completely implementation independant
Specific comments:
1. multiple values for an attribute:
it seems but is not explicit that your choice is to have
n single-valued attribute-value pairs.
An alternative solution (see RFC-822) could be
[attribute_name]:[list-of-value] (with some separator)
I think your choice is preferable, but I would like to see this
choice
- justified
- explicitely stated in the draft
2. character-sets:
there are some unclear points
-- a value is a text string, specifics left up to ....
do text string means USACII text string?
then a common method to represent other char-sets must be given
to avoid each specification reinvent a new method
else: there should be a specifier of the char-set and representation
in any case a MIME compatible solution is to be choosen and
specified, in fact a general method will also allow such things
as compression (with a compression algo identifier etc...)
3. structuring precedence
I don't like too much your precedence based structuring, and would
prefer a real explicit nesting mandatory in any case.
A grammar specification is required!
4. section 5: ??????????
1. The sentence:
In order for URCs to be useful they must be contained in some
type of network based retrieval tool.
makes no sense : a URC contained in a tool??????
2. the whole paragraph is not related to its title (Usage of URC)
3. all the stuff about whois++ is irrelevant in a doc about encoding
and use of URC, it is a section of applicability of whois++
to store and retrieve URC and must be in some other document
