Add Dineh (Navaho), don't want to inflame the Joint-Use Area conflict
any further, though Hopi do go Republican (those who "vote"), unlike
the majority of Dinetah and away-Dineh voters. Bear in mind that the
core of claims by Indigenous Peoples in the current and former British
North America and their successor states, apply to the English Crown
(in Right of Canada, and unsevered by the Treaty of Paris), and do not
make reference to theories of (immigrant) civil rights or equity.

We'd still like a recount, thanks awfully, even if conducted in English.

some of the folks on this list aren't american or US citezens and
might think that this is a bit presumptious.....but here goes:-

the first thing the white house should do is educate its customers and
organise voting properly

the next thing it should do is apply for membership of the European
Union

following that, the use of other languages might be a considerably
benefit - e.g. spanish, chinese and hopi spring to mind

finally, what fee is being paid for this, and in what (stable)
currency, and under which tax treaty?

I did some poking around Microsoft's Technical Support web site and found the
following KB articles:

Q250983 "Using Netscape Server Push Technology with ASP"
http://support.microsoft.com/support/kb/articles/Q250/9/83.ASP

Q151504 "Using Server Push with IIS"
http://support.microsoft.com/support/kb/articles/Q151/5/04.ASP

Q234266 "High-Speed Push-Technology Program May Overwrite Internet Cache"
http://support.microsoft.com/support/kb/articles/Q234/2/66.ASP

(That last one might not be relevant but I thought I'd include it anyway)

I then did some searching on Deja.com (and saw your posts) and found the
following:

"Re: Is Multipart MIME valid in HTTP?"
Date: 08/09/1999
http://www.deja.com/getdoc.xp?AN=510624816

"Re: help:Mime Multipart for downloading"
Date: 02/02/2000
http://www.deja.com/getdoc.xp?AN=580779940

I found a few others too but didn't include them here, but based on what I *did*
see, the results don't look too promising I'm afraid. It's beginning to look
very much like you're S.O.L.

One thing you *might* try is changing your Content-Type to
"multipart/x-mixed;..." or "multipart/x-mixed-replace;..." I noticed on my
system that when I did that, I *almost* got it to work the way you want it to.
Internet Explorer did present me with a "Save As" dialog box, but it was
immediately overlaid with another error dialog complaining about the fact that
it was unable to retrieve the file attributes for "header.hdr". from the test
site I was using. I then uploaded some dummy "header.hdr" and "content.pld"
files and tried again and this time it *appeared* to work, BUT... didn't quite.
When the files are actually present on the web site that sends me your above
multipart response, it does indeed present me with a "Save As" dialog box and
allow me to save it, BUT... 1) it only presents me with ONE "Save As" dialog box
(for "header.hdr" -- the first file) and not two, and 2) the file content that
get saved in the "header.hdr" file consists of the actual entity body of
received message: i.e. the entire MIME contents from the first boundary to the
last (i.e. the entire stream).

I don't know what else to say. From what I'm seeing It looks like Microsoft
Internet Explorer doesn't support what you're trying to do.

If you *do* figure it out, be sure to let us know what you did to get it to
work. From the looks of it there are a lot of others out there who'd be very
grateful.

Good luck!

The request from the client is a GET request. The headers from the request
are as follows:

User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,

Accept-Encoding: gzip, deflate
Accept-Language: en-us
Connection: Keep-Alive


The server sends a multipart/mixed document.
I have a sample servlet that sets the following properties for the
HttpServletResponse followed by the body.
The content-length is set correclty to the size of the body.

MIME-Version: 1.0
Content-Type: multipart/mixed;boundary=D8119DDD2D264D4480E57277
Content-Length: <length of the stream>

--D8119DDD2D264D4480E57277
Content-Type: application/octet-stream
Content-Disposition: attachment; filename="header.hdr"

This is a sample header

--D8119DDD2D264D4480E57277
Content-Type: application/octet-stream
Content-Disposition: attachment; filename="content.pld"
Content-ID: <content.GetMultipart@...>

This is a sample content body.

--D8119DDD2D264D4480E57277--


As mentioned earlier, Netscape prompts twice to save the contents in
header.hdr and contents.pld
IE simply displays complete body including the multipart boundary strings.

Any help will be highly appreciated.

Hard to say without seeing the actual request/response being
sent.

If you could let us see the actual request that your server
received and the actual response that your server sent (minus
the actual content of course), we might be in a better position
to help you.

pravin@...

Hi

How can I send 2 files from the server in one stream (in one request from

the client). I have been trying to achieve this

using multipart/mixed format. I am able to do this with Netscape browser but

not with IE.

Can IE handle multipart/mixed message from the server correctly.

The server is sending a Content-Type as multipart/mixed. The message

consists of 2 body parts and

each has a Content-Type set to octet-stream. Netscape prompts the file

dialog twice and for each file

get the name from Content-Disposition of each body part (and this is the

desired behavior by me).

It seems IE fails to understand the message and simply displays the whole

message with all the headers etc.

RFC 2616 (HTTP 1.1) states "In general, an HTTP user agent SHOULD follow the

same or similar behavior as

an MIME user agent would upon receipt of a multipart type."

Is this a known bug (non compliance with HTTP protocol) with IE( 5.0 and

5.5) or I am doing something stupid.

Any help will be highly appreciated.

Thanks

Pravin Singhal.

I know for a fact that some servers stream their responses back if you
stream your requests to it, but I never bothered to make a list. Is that
what you're asking? Which specific servers out there (e.g. Apache,
Netscape, etc) are actually capable of streaming? If that's your
question, I don't know because I never bothered to keep track. I just
know some of them do because I've seen it in my trace logs.

And which specific clients (i.e. browsers, e.g. Netscape, IE, Opera,
etc) stream (pipeline) their requests, I don't know either. I never
bothered to check as it's hard to tell from my trace logs (since each
HTTP request my proxy processes is handled separately).

But if you're asking whether streamed HTTP requests/responses actually
get packaged together into the same physical TCP/IP packet, I would
venture a guess and answer: "more than likely" (unless you've purposely
disabled the Nagle algorithm, which is highly discouraged).[1]

[1] The Nagle algorithm can be disabled by setting the TCP_NODELAY
option for a socket via 'setsockopt'. For more information regarding the
Nagle algorithm, see RFC 896.

You have to distinguish, here, between the Clippings service which is
available
via Palm VII and the little-p palm class of devices, which can have access to
the 'weal' WWW using other services accessed with the aid of e.g. the OmniSky
modem that works with the Palm V.

But I am likewise unaware of any gateway that offers access to the whole real
WWW as Web Clippings.  There are several WWW to WAP gateways which I found by
digging at C-Net.

[Plug warning]

If you're interested in this topic you might be interested in the
discussion we
presented at Supercomputing 2000:

I don't know if this is what you mean, but you can use this service:

http://gelon.net/cgi-bin/wapalizeericssonr320.cgi?url=http://wmlproxy.google
.com/wmltrans/u=www.w3.org@2FTR@2F

Put your URL after the u= portion and replace all slashes with "@2F"
(without the quotes).

Hope this helps,

This accomplishes precisely nothing, as was explained ad nauseum on
the www-xml-sig list.  (Isn't it *finally* time to make that archive
public?)

Instead of the handwaving with a URI of indeterminate (semantic)
content, we can do better *with* the um, gobbledegook.  It has the
virtue of having been an international standard since 1986, and the
incidental benefit that we know what's going on with each URI.

1. In the internal subset:

   <!-- Declare formal definition of a machine-processable format -->
   <!NOTATION XSchema
              SYSTEM "http://www.w3.org/2000/08/XMLSchema"
              >
   <!-- Declare an entity formulated in this *particular* format -->
   <!ENTITY   xhtml-schema
              SYSTEM "http://www.w3.org/1999/xhtml/schema"
              CDATA XSchema
              >
   <!-- Enable a reference to this entity -->
   <!ATTLIST  xhtml
              foo    ENTITY    #IMPLIED
              >

2. In the instance:

    <!-- Reference the entity, at the same time pinpointing which
         particular formalism was used -->
    <xhtml foo="xhtml-schema">
    ...

[I named the attribute 'foo' deliberately to make the point that the
notation on the entity tells you all that you *need* to know: that a
schema of some kind exists (as the contents of the entity) and also,
much more importantly, which particular formal system it's encoded
in.  Given that, the mere name of the instance attribute need not be
relevant.  One *could* formalize it using a reserved name, i.e. using
a 'xml' prefix, though.]

As a matter of fact, with the new provisions in WebSGML TC, the entity
declaration can be skipped in favor of a direct reference *as* the
external subset

  <!DOCTYPE xhtml SYTEM "http://www.w3.org/1999/xhtml/schema"
            CDATA XSchema [
      <!NOTATION XSchema
              SYSTEM "http://www.w3.org/2000/08/XMLSchema"
              >
  ]>

But not quite yet in XML, admittedly.  See K.4.10.3 in

   http://www.ornl.gov/sgml/sc34/document/0029.htm

Denigration and disparagement have been known to work.  Meanwhile, the
idea is to poison as many things as possible with colonified names,
just to make recovery more costly (and hence defered/avoided) -
nothing like making a virtue out of um, "necessity".

Not to mention that DTD syntax can be used to invoke the processing
of schemas in reliable ways.  See above.

XML "validation" is useless.  It's crippled in relation to SGML
facilities, and even SGML has moved beyond the implicit assumption of
an encompassing architecture.

The "name clash" non-problem that SGML-bashers are still getting
mileage out of.  For a excellently written neutral presentation of
the basic "problem",  see, e.g.  Q8.5 in the Namespaces FAQ

   http://www.rpbourret.com/xml/NamespacesFAQ.htm

For a demonstration that the problem is illusory, using tools that
have existed since before XML was invented, see

   http://www.nyct.net/~aray/sgml/demo/dept/

Except it has the same problem as the STYLE attribute (and to a large
extent, the STYLE and SCRIPT elements in HTML): an implicit assumption
that there is only *one* "relevant" formalism.  My prediction is that,
just like SCRIPT and STYLE, in the future for XSchema lies the problem
of "versions".  For which, of course, yet another reserved attribute
will have to be invented...

And now, to really give the W3C folks heebiejeebies, may I suggest a
perusal of this tutorial:

   http://www.isogen.com/papers/archintro.html

I also by chance discovered in old directory on an old machine this
piece by Eliot Kimber, a copy of which I can't locate elsewhere.

   http://www.nyct.net/~aray/notes/rdfarch.html

(It was written in Aug 97, and references the 970801 draft of the RDF
spec.  It's mainly a source of ideas now, since the details have
changed.)

Hi,

we have several pages that we want to be accessible to PDA  users.  Are
there any public clipping gateways that will let us filter our pages
through and see how they look on a portable device (doesn't have to be
exact)?  They can also be stand alone emulator apps.  We did look at Palm's
emulator, but it seems it requires an actual modem and most importantly an

Yes, XSLT is near impossible for most HTML-only people to learn, and XML
gives them too wide a range. However, I firmly believe that WYSIWYG RDF/SW
editors/browsets will fill the much needed gap. Tim had something like that
running on his NeXT machine, but they took the editing function out when
they ported it. oops.
Come on someone, there's a fame and fortune waiting for the person who
creates an easy to use SW format, and then makes a neat little tool for it.

With pleasure.
SW Format: I believe that the best scenario for creating an interfacable
Seamntic Web (SW) is to provide a framework that is based on XHTML and RDF:
i.e. a sort of hybrid document/data format. I tried to do this myself with
annotations, but as usual got a bit bogged down. At the end of the day we
need a format that is Semantic but can be easily rnendered using CSS. Plain
XML can already acheive this, but doesn't have the correct smeantics (too
broad), so I think an XHTML/RDF hybrid is a good direction to go.
SW/SW Editor: The problem is that this format will be quite necessarily
complex. Therefore, you would need some kind of WYSIWYG editor for it. It
should also be able to partially understand other well described XML/RDF
formats, ala "Partial Understanding" in TimBL's design notes (forgot the
URI).
What is required is an editor/browser that can reder/understand/display a
documentized form of RDF, as well as understanding any other RDF. In other
words, it should be possible to store all of your data as a form of RDF
(with a few extra semantics) and broswe and edit it quite easily. I have
already showed it is possible to store data as RDF and documentize it on the
fly. With XLink capabilities and CSS added to the mixture, the hypermedia
possibilities are endless!

Exactly. A big reason I'm going with a non-XML templating system is because
I want normal people to be able to use my system easily, with a minimum of
fuss. It's difficult enough teaching them HTML (and I hope that will someday
not be necessary), but trying to teach them XSLT is next to impossible.

If Schemas and RDF are difficult to programmers, what about the whole rest
of the world out there who fell in love with the Web, but doesn't want to

You can't seriously want me to belive that programmers are people too :-)

Some of the trouble with RDF and Schemas is their complexity, but also the
fact that they are unlimited in their uses. Whereas XHTML is very simple in
it's aim, and powerful in its results, RDF is *too* powerful for people
(most people, not programmers) to get to grips with. That's why I dream of
creating hybrid systems like ADotSW http://www.mysterylights.com/sbp/adotsw/
I think that the RDF syntax would need canonizing before it were to be used
by the huddled masses, as many can't even cope with HTML, but they don't
need to use it: what we *do* require/demand are tools for the Semantic Web,
that can automatically browse/render/edit this kind of stuff: so we wont
have to see all of the coding. We need a Mosaic for the SW.

You said it. The only problem I have with it is that it should be
accessible to "people" and not *just* to the "subsetof" called
"programmers". Just as Aaron is beset by principals/administrators/teachers
and other lowlifes, we are held captive by computer science graduates in
white lab coats speaking in tongues. My dream is that we can set us free.
As Huey Newton and them said "Power to the People!" so I say "Schemaker

Hopefully we will be able to say "when", but we all know that DTDs aren't
going to just "vanish". They are highly important for defining document
formats, just as Schemas are for defining data; they have different roles to
play. What we (in fact the HTML WG) have to decide is whether (X)HTML is a
document or data format, and they have to do it for XHTML 2.0.
I suppose using namespaces to point to Schemas would reduce the prologue,
and the file size and editing-by-hand time, but I can't help remembering who
*suggested* we put that "DTD gobbledygook" at the top in the first place(!):

[[[
So if we're commited to SGML, let's start putting something like

http://lists.w3.org/Archives/Public/www-talk/1992JulAug/0016.html

Also:-

[[[
(we don't have to store it in the mfile -- servers that distribute
HTML could generate it on the fly.)
]]] - ibid.

Indicates that you *knew* people wouldn't bother adding a !DOCTYPE
declaration to the top of their files.
8 years down the road, and 99.99% of all Web documents aren't valid SGML or
XML. I blame Mosaic personally; although it did wonders in promoting HTML
and the WWW because it allowed almost any crud code, it has almost destroyed
it for the same reason. Winston Churchill said, "Success is not the end of a
story", and just because the WWW is going O.K. now, I don't think the
architectural principles are strong enough for it to retain its integrity
for much longer. They may have been in the first couple of years, but the
only trace of them now is a web site named http://www.w3.org/

[Note that the original DTD for HTML by Mr. Connolly was in
http://lists.w3.org/Archives/Public/www-talk/1992MayJun/0020.html]

> I'm asking for one lousy attribute,

I don't believe it will *be* just one lousy attribute, because validating by
namespace is only a very small part of the list of options in the XML Schema
specification. I agree that it may be the best way, but it's not the only
way. You will have to allow for xsi:SchemaLocation, which will bump up the
prologue aspect of validation again. You can't use "the file gets smaller
and simpler" as an excuse to use XML Schemas for XHTML: instead use the fact
that they have certain benefits over XML DTDs.

I don't get your qualms there, "one big unmanaged centralized namespace"? If
you mean http://www.w3.org/1999/xhtml then that's probably the same NS as a
Schema version would use (except they'll probably change it before then for
2.0...well they should do if the modules are going to change).

It's a good approach. That way, instead of just declaring the namespaces in
a DTD and not using them, you don't have a DTD at all and simply use the
namespace to point to your Schema.

I agree. Not to mention the upcoming RDF...

I know how to insert it into a document, I meant how do we have it validate?
We use RDF Schemas for RDF, which *don't* offer any sort of structural
scheme for the attributes and elements used in RDF. That is quite a
nightmare, and it means we can just mix RDF namespaces freely (within the
bounds of the RDF M & S recommendation).

I wrote an XHTML module for Dublin Core:
http://xhtml.waptechinfo.com/modules/rdf/rdf.mod
So it can even be done in XHTML m12n. Maybe if we ever get a Schema version
of XHTML, I'll attempt to write a Schema for it too...

I like the way you used it as a cover for the actual target namespace
(http://www.w3.org/2000/08/comment# ) in case the XML Schema specification
changes (which it did). It means I'll have to write a new Schema though....

Ugh...if you had have done, it would have saved me a lot of time and effort!
RDF seems to be the way the Web is gravitating, but a lot of people don't
like the rigidity:-

[[[
[...] People who put up web sites got an immediate benefit: they had access
to their data from anywhere and could easily share that data with anyone wit
h a web browser.
Unfortunately, the new work on technologies such as RDF and XML do not have
this benefit. I see no benefit from providing my information in these
formats -- it just means more work for me. No web browser can view these
formats, and it seems as if they never will. Unless, of course, I write more
files: XSLT transformations to display it properly and DHTML code to modify
it, the list goes on.
Needless to say, this isn't going to have very many people jumping to use
these new formats.
]]] - Aaron Swartz, Blogspace

But then Aaron, in his attempts to overcome this problem, is having to use a
proprietary templating system as an interface and storage medium for a
database. The motto seems to be "if you can do it yourself, then do it using
the easiest means possible". I think if people pulled together and actually
created a Semantic Web by bending some of the W3C specifications (XHTML,
XML, RDF etc.) together, then it would work. But not many people are
inclined to try, even if a large handful *do* see sense...

Needless to say, when Aaron releases the source for his (in my opinion
incredible) new invention, I'll be converting it so that the document
template medium is in XHTML/RDF...or at least I will do if I can work out a
method of doing so based on my [1] ADotSW work.

Try mixing DTDs with Schemas, it's very hard to do, but not impossible.

I think it is possible to build up a database fully in RDF, possibly
utilising XHTML and ADotSW [1]. However, I am always reminded of the
exchange
between myself and Mr. Bingham in an ERT conference:-
[[[
HB: [...] [in SGML] we defined that element names can be as
      expressive as you like.
SP: But attaching behaviours?
HB: No!
]]]  20 November 2000 W3C WAI ERT Telecon

Which sums up a very important architectural fact: attaching behaviours to
markup sucks. Everyone knew that in the early days of the Web, but then
Mosaic came along...and although Mosaic catapulted the Web into (in)famy, it
did so in a way that meant "within itself it contained the seeds of its own
destruction". Now those seeds are starting to germinate, and if you'll
excuse the furthering/killing of the analogy, we need some weedkiller fast.

[Strangely enough, XHTML still has a lot of behaviours left ruminating
within, so maybe the aim for 2.0 is to provide a version that could be
understood in "processors" that have no foreknowledge of XHTML and it's
behaviours. RDF anyone?]

This is the kind of strong Web architecture that I was talking about.
Partial credit though, for not outlining many implementation methods. In
fact, the document is a bit of a bore after a couple of reads "been there
done that". Some of the other stuff in the Design Issues
(http://www.w3.org/DesignIssues/ ) series is a lot more interesting.
People are still only just coming to grips with the WWW and what it means,
even though it is ten years old now.

That's an all important quote, and a bit nauseating. Anyway, it is never the
experts that get the final say, only the huddled masses (i.e. users), and so
all of the conversations we are having are irrelevant and useless even if
they do map out a solid roadmap for the WWW :-)

Certainly: it's the XHTML Common Attributes Module:-
http://www.w3.org/TR/xhtml-modularization/DTD/xhtml-attribs-1.mod

It takes 6 DTD lines to add it into XHTML 1.1 (it would have been 4, but 2
of the lines are broken down by convention), and it could have only been
two, but it isn't because it requires lots of modularization. Also, you will
need to create a QNames file for your "util" prefix, denoted here by the
entity %util; (creative of me...)

<!-- Module for util:comment --->
<!ATTLIST %Core.extra.attrib;
      %util.comment.attrib;
>
<!ENTITY % util.comment.attrib
      "%util;comment        CDATA          #IMPLIED"
>

Which isn't all that bad, you have to admit. It adds the util:comment
attribute to any place that the core attributes would be added.

There are quite a few ways in which to semanticize XHTML. Try reading [#1]
http://www.mysterylights.com/sbp/adotsw/ and excuse my plug. If the HTML WG
are planning on making XHTML 2.0 a pure data format, then they should have a
look at it. In my opinion, HTML was always going to be a document format,
right from the start, but now it's time is over, and maybe it's best to just
start again, or make some radical changes.
There must be some decent method of creating a semantic web hypermedia
system that is accessible, usable, and more solid architecturally. Maybe it
would start with stuff like browser/editor combinations that allow you to
make your own personal webspaces with direct WYSIWYG editing. I dunno
really, I am not as much of a genius as most of the people I work with, or
am sending this to, so maybe someone else will come up with a better idea.

If it starts with http://www.w3.org/TR/ it should be ;-)

It works on the W3C's Xalan server, but the output isn't in XML or RDF.
Maybe the following would be better:-

<xsl:transform
     xmlns:xsl  ="http://www.w3.org/1999/XSL/Transform" version="1.0"
     xmlns:util ="http://www.w3.org/XML/2000/04schema-hacking/comment#"
     xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
     xmlns:dc="http://purl.org/dc/elements/1.1/"
     >
<xsl:param name="xmlfile" />
<xsl:template match="/">
<rdf:description>
    <xsl:attribute name="rdf:about">
     <xsl:value-of select="$xmlfile"/>
    </xsl:attribute>
  <rdf:bag><xsl:apply-templates/></rdf:bag>
</rdf:description>
</xsl:template>
<xsl:template match="*[@util:comment]">
<rdf:value title="util:comment value">
   <xsl:value-of select="@util:comment"/>
</rdf:value>
</xsl:template>
<!-- don't pass text thru -->
<xsl:template match="text()|@*">
</xsl:template>
</xsl:transform>

Which should give an output in RDF, and one that can be parsed in SiRPAC
(or: hopefully...as Mr. Loughborough doesn't like me saying!).

Well, it's a few months later, and I'm still trying...
The problem is that the XML Schema specification is so intensely boring that
I can't help but fall asleep every time before I get to the end. Maybe I
should start from the end and work my way backwards ;-)
RDF is better, but it's still a bit of a pain because there aren't all that
many decent implementations of it. Dublin Core, RSS and DAML. Great...

Update: I still believe that a "util:comment" attribute would add much
needed semantics to XHTML (c.f. http://www.mysterylights.com/sbp/adotsw/ ),
but the purported extensibility of XHTML oft' referred to in Mr. Connolly's
reply opened up a world of m12n, Schemas, and RDF for me, and I haven't
looked back since.

In summary, I believe that the architectural principles described in Mr.
Connolly's reply based on his 8 years of Web experience were very sound
indeed, and that they are solid foundations with which to build a Semantic
Web on. Namely points like:-

      1) Exterminate the use of DTDs for data formats.
      2) Use RDF for metadata in XHTML.
      3) Always make sure you can validate your code.

But we have to acknowledge that the Web's architecture was always unstable,
and at present is almost shot to pieces. I think it might be a good idea to
actually try to *enjoy* the Web that we have today, whilst 1% of the pages
actually work and make sense. After all, when the day comes that we look
back on "the times when we could use one browser to view the Web, rather
than the 17 we have to use now", we will remember these times as the Web's
golden age.

I don't know.   You might be able to find statistics about the use of this
header on the W3C's web characterisation pages.

Most, if not all, modern browsers will only send if-modified-since headers
with exacly the same date as was in the last-modified header of the
response they try to revalidate.

All HTTP/1.1 implementations should, and I believe that by now most of the
browsers and proxy caches out there implement HTTP/1.1.

Hi,

My name is Peter Loeb.  I have written an XML application which I call
XMidi.  It allows a MIDI file (.mid) to be converted to an XMidi file
(.xmi, an XML file), and an XMidi file to be converted to a MIDI file.
The supporting program is in Java (open source).

Workshop Outline

  The "Semantic Web", a term coined by Tim Berners-Lee, is used to
  denote the next evolution step of the Web. Associating meaning with
  content or establishing a layer of machine understandable data would
  allow automated agents, sophisticated search engines and interoperable
  services, will enable higher degree of automation and more intelligent
  applications. The ultimate goal of the Semantic Web is to allow
machines
  the sharing and exploitation of knowledge in the Web way, i.e. without
  central authority,  with few basic rules, in a scalable, adaptable,
  extensible manner. With RDF as the basic platform for the Semantic Web,

  a multitude of tools, methods and systems have just appeared on the
  horizon. The goal of the workshop is to share experiences about these
  systems, exchange ideas about improvements of existing tools and
  creation of new systems, principles and applications. Also an important

  goal is to develop a cooperation model among Semantic Web developers,
  and to develop a common vision about the future developments.

Relevant workshop topics include (non-exhaustive list):
    · Language and Representation issues
    · Semantic Web infrastructure and architectures
    · Metadata and conceptual models for annotating content, resources,
and portals
    · Automatic annotation/tagging/metadata creation and recommendation
    · Tools, systems and methodologies for Semantic Web
    · Application of  semantic web technology
    · Migrating information to semantic formats & Information Filtering
    · Trust in the Semantic Web
    · Query languages for the Semantic Web
    · Information correlation, integration, mediation and brokering on
the Web
    · Resource discovery
    · Distributed inference services
    · Semantic Web mining

Important Dates

  Deadline for paper submission 1 Jan 2001
  Notification of acceptance    1 Feb 2001
  Deadline final contributions  1 Apr 2001

  All accepted papers will be published in the workshop proceedings.
  In addition, a few selected best papers will be considered for
  publication in a special issue of the ETAI Semantic Web Journal
  (http://www.ida.liu.se/ext/etai/).
