Trying it out

[Leigh Dodds]

Hi all, just catching up on the recent list traffic...

Thought I'd throw out a few pointers which came to mind.

Some recent relevant discussion (on XML-DEV) regarding the marking up of
names
[1,2,3,4,5,6] (Personally I like the format proposed by John Cowan, see
[4]).

These are good points - it is certainly worth looking around to re-use
'standard'
markup conventions where posssible. The Dublin Core Metadata Initiative [7]
may
be one useful resource here. For example they specify qualifiers for
some elements (e.g. creator/contributor) [8, 9] which allow identification
of name,
affiliation, etc.

Even if the exact markup is not used, there are usually useful lessons to be
learnt.

There has been some discussion regarding producing an XML version of the
current
discussion proposal. Alongside this issues such as version numbering, date
last
modified, descriptive text, etc. These can be viewed as metadata describing
the markup. There are some XML 'patterns' which relate to this area [10,
11].

The XML patterns site [12] is an excellent resource for information on
defining
good XML document types.

I've become increasingly convinced lately that the RDF model [13, 14 (useful
introduction)] may be useful in this
context. For those who are not familiar with RDF it essentially allows one
to make
assertions about particular objects; expressed as 'triples'.

e.g. socrates is a man, the leaf is ovate.

Still mulling this one over...
