These were transcribed by Christian Morgansen, who handed them
to me cuz he couldn't find you and I didn't duck fast enough :-)

They should be considered in the preparation of the workshop report.

Sorry for the delay in forwarding them.

Group 2: Stu Wiebel
	Christian Morgensen

Problems addressed:
	* Describing a page's content; i.e. providing metadata in HTML
	* Packaging and describing collections of documents

Related Standards:
	* HTML 2.0 META and LINK tags
	* REL/REV draft: 

Goal: avoid introducing new tags into HTML (since folks won't
be able to create them with existing authoring tools)

Scope: Proposing and infrastructure and suggesting some basic terms
for content providers to use.

Time Frame: less than three months to implement

Describing Pages
- ----------------

Use the meta tag to provide meta data.

Problem: NAMEs are a flat namespace

Solution: partition NAMEs into sevarl spaces, using a dot separator
	e.g.: <meta name="dc.author" content="...">

where "dc" is the schema, "author" is the field.

Users can provide data for sevaral schemes without conflict.

Resolve schema names using the LINK tag.

e.g.: <link rel="schema.dc" href="http://oclc.org/dublin_core">

The page contains a description of the fields used in the scheme
(human readable or machine readable)

Suggestion: the field descriptions are named anchors, so that search
engines can link to the specific field descr.

The schema URL is the unique key the index uses to determine the exact
schema. The OCLC has offered to host a schema registry. [note from Dan:
using URLs obviates the need for this registry]

Action item: settin up a dublin core description page
	Dan Connolly to write proposal for inline marking of metadata
	(out of scope for today)

- ---------

Use the LINK tag to create typed links. Use REL and REV type HREFs on
existing and new content.

in HEAD: <link rel="title-page" href="../index.html">
in text: <a href="../index.html" rel="title-page">title page</a>

Some suggested REL types:

[Dan's note: see original list at:
	http://www.w3.org/pub/WWW/MarkUp/Relationships ]

parent: useful for navigating clusters [Dan recalls that lycos rep
	said it could be used to heuristically determine the priority
	of indexing a page]

icon_for: for putting customized icons on results lists

title-page: a papaer front page, TOC, etc.
home-page: site's front page

A subsidiary page LINK REL="title-page" to it table of contents.
The title page has several LINK REV="title-page" to each of
its constituent pages. It also has a LINK REL="icon-for" to a GIF
of the book cover image.

The <meta name="site-name" content="..."> allows home pages to
publish an index-friendly name in addition to the usual <TITLE>.
Allows indexer to use something more descriptive than site DNS name.

Action item: educate content providers, tools builders
	Document what indexers look for and use

- ---

syntax of description scheme:

	<meta name="schemename.fieldname" content="free text ...">

	<link rel="schema.schemaname" href="uri">

	(alternate suggestion was to put the schemaname in
	a separate attribute of LINK, but this would require
	changing the authoring tools. The above syntax
	has the advantage of working with existing tools
	like Hotmetal)
