Dear all,

You are receiving this Limited Call for Participation in the second
DELOS workshop because you are either on one of the ERCIM digital library
mailing lists, a participant in the Warwick initiative, or because you
wrote to me requesting information.

We would like to open up this second workshop to increased participation
by European researchers, but do not want to publish a completely open
call, as we wish to keep the workshop small, productive, and focused.
Please pass the word on to colleagues.

I look forward to hearing from you.

Best regards,
Tom Baker

Second DELOS Workshop
Bonn, Germany, 7-8 October 1996

Topic: Interoperability and Metadata

The second workshop of the DELOS Working Group, to be held on Monday and
Tuesday, 7-8 October 1996 in Rhoendorf, near Bonn, Germany, will examine
issues related to interoperability and metadata.

The first day of the workshop will focus on the Warwick Framework, a
container architecture for metadata that has been the focus of a series
of international workshops over the past year.  Carl Lagoze, Stuart
Weibel, and Clifford Lynch, key scientists of this initiative, will make
presentations on recent progress made.  Other participants will be asked
to review the current state of implementation of the Warwick Framework
and Dublin Core and to make brief position statements on its relevance
to their current work.  Depending on who attends, we would like to form
break-out groups to produce recommendations on implementation within
ERCIM, to identify research directions for future projects, or even
to advance specific technical topics.  Given the workshop's timing, I
believe we have the opportunity to contribute significant momentum to
this important development.

The current literature on Dublin Core and Warwick Framework can be
found at http://purl.org/metadata/dublin_core.  Note in particular
"An Approach for Embedding Metadata in HTML 2.0" by Stuart Weibel, a
recent W3C workshop consensus that included USGS, Webcrawler, Lycos,
and Microsoft; and "The Warwick Framework: A Container Architecture for
Aggregating Sets of Metadata" by Carl Lagoze, Clifford A. Lynch, and Ron
Daniel Jr., which will be published as a Cornell University technical
report and linked to the Dublin Core page within the coming week.

The second day will focus on interoperability between systems based
on HTTP, Dienst, Z39.50, agents, and CORBA.  We are keeping the range
of topics more open here and strongly encourage participants in the
SAMOS project, in particular, to take the opportunity to examine
interoperability issues related to Dienst.  Here is a keyword list of
potential topics for the two days:

Warwick Framework for metadata
Other metadata formats
    e.g. Dublin Core, SOIF, IAFA templates, PICS, conspectuses, finding aids
Metadata implementations
    e.g. SGML, HTML, MIME, VRML, CORBA
Domain-specific and specialized metadata or negotiation protocols
    e.g. terms and conditions, charging, labels, archival responsibility
Distributed Systems Architectures and Interoperability
    e.g. HTTP, Dienst, CORBA-based, Java-based, Z39.50
Naming issues (Object Handles)
    e.g. URNs, CNRI handles, PURLs
Federated indexing and retrieval
    e.g. Z39.50-like protocols for document retrieval, conspectuses,

The workshop will take place in a small, picturesque village on the Rhine
south of Bonn.  As in Sophia-Antipolis, we plan to start with a reception
on Sunday evening.  Time and interest permitting, we may arrange for a
winetasting at a nearby vineyard on Tuesday.  The estimated costs are 700
DM per person (from Sunday night through Wednesday morning), including
all hotel rooms, meals, coffee, and winetastings.  DELOS will be able
to reimburse the costs of one or two researchers per ERCIM institute to
make a presentation at the workshop.

Anyone interested in participating should send a short position paper to
me by 31 August (I will be away for most of July).  Participation will
be limited.
