Subject: [Moderator Action] [Fresher to webdav] How to implement WebDav
http extension methods in Java

Hi All,

 I am a new comer to this subject. I am looking to implement a client in
Java
 which can communicate with WebDav enable server. However it looks like
Java's
 networking classes like URL, URLConnection and HttpURLConnection only
 support standard HTTP methods. Do I need to look at sockets to implement a
client
 or is there a better way available?

Thanks in advance.

You may want to have a look at http://jakarta.apache.org/slide/index.html.
It includes a Java open source implementation of a WebDAV API.

I'd vote for the latter (i.e. just refer to the property without
the namespace), but either is OK by me.

I also think the latter is better readable.

As an alternative (I think) James Clark once proposed
to use a wording like
  {http://www.w3.com/standards/z39.50/}Authors
if a name with namespace needs to be mentioned.

But if the namespace is clear from the context, why bother...

I had some trouble with Jakarta Slide on the client side. I have had
more success with SkunkDAV.  It seems more intuitive to me.

This message marks the end of the WebDAV Working Group last call for
comments on the WebDAV Access Control Protocol specification,
draft-ietf-webdav-acl-07.  This last call period began on Friday, November
9,
2001, and ended December 3, 2001. The message starting the last call was:
http://lists.w3.org/Archives/Public/w3c-dist-auth/2001OctDec/0178.html

While the last call period has ended, you may still submit comments on
the -07 (or later) revision of the specification. My best estimate for the
completion of a new revision of draft-ietf-webdav-acl is December 7 (this
Friday). As well, due to the IETF meeting, a new Internet-Draft can not be
submitted until the end of this meeting (December 17), so any comments
submitted before that time would be easily incorporated into the next
revision. Note that with the end of the last call period, the burden of
evidence required to effect a significant design change in the protocol is
now much greater.

My characterization of the comments received during this last call period is
that fixing them requires generally minor changes to the specification. This
leads me to believe that the specification has, in fact, resolved known
technical tradeoffs, and is stable. As a result, unless feedback to the
contrary is received from the Minneapolis IETF meeting, I intend on
submitting the next revision (draft-ietf-webdav-acl-08) to the IESG for
approval as a Proposed Standard. There will be no further last call for
comments period within the working group, although there is one last
IETF-wide call for comments that will occur, initiated by the IESG.

Here's the agenda I sent in.. I canvased a few people very last-minute for
agenda items, but if I've missed any we'll cover them during agenda bashing
and surely be able to squeeze them in.

I am very pleased to announce that Lisa Dusseault, Xythos <lisa@xythos.com>
is now Co-Chair of the WebDAV Working Group.

Lisa and I will be working together to finish existing specifications
(access control, advanced collections), and to revise existing ones (RFC
2518 revision). There is a lot of work ahead of us, but I am confident that
with Lisa as Chair, we'll be able to make steady progress towards reaching
our goals.

Co-Chair, WebDAV Working Group

Super -- thank you very much for posting your comments on this
specification.

At present, it has gone through a last call, which resulted in a list of
issues being recorded:
http://www1.ics.uci.edu/pub/ietf/webdav/collection/bind-issues.html

The editors of the document held a series of teleconferences about the
specification, minutes from which are available towards the bottom of
http://www.ics.uci.edu/pub/ietf/webdav/  Resolutions to issues have been
recorded in the issues list.

> Is anyone actively editing or revising the document?

At present, no. It has been my intent to work on this as soon as the access
control specification is completed. Since the ACL specification is nearly
complete, I anticipate working on this specification soon. We'll have
another last call, perhaps two, and then it'll get sent off.

None that I know of, though I have always felt that this capability is
needed before most document management systems can expose their full
functionality via DAV.

Sorry for the cross-post -- I suppose this should be going to just the
DASL list, but there seems to be more spam on that than actual traffic.

It seems like not much work is happening on DASL.  I haven't seen any
clients, for example, that use it.  Is this a misimpression?  Or is
there just not enough interest in it?  Or is it too hard to do?  I'd
like to be wrong about this, so please correct me if that's the case.

Thanks.

Actually, I've been seeing a recent increase in interest for DASL -- there
was a fairly substantial off-list thread last week. I've encouraged people
to move discussion back on-list.

Unfortunately, there is currently limited client support (anyone out there
have a DASL client?). The Xythos Storage Server supports DASL on the server
side. I think this is more an indication of the lack of server support, and
this, in turn, is due to the immaturity of the specification.

I think there is a lot of interest in DASL, since it dramatically increases
the value of DAV properties.

Hello,

You're probably right about the clients; there are a few known servers that
support all of DASL, but I don't know of any clients.  (If there are any,
please speak up.)

I do know clients that support the DASL framework, but the search syntax is
SQL rather than XML.

Do you think there are any problems with the specification?  Would you
support it at some point if it started moving through the standards process
again?

Lisa

I've only briefly looked at the spec, will let you know once I take a closer
look.

We're definitely interested, but of course the lack of client support makes it
somewhat academic right now.  Hopefully that will change if/when the process
starts moving forward.

I remember the recent question about DASL (was it this list?).
I was wondering if part of the problem with DASL is the question
of whether it addresses a need, or addresses it appropriately.

We have a text searching engine that can do lots of funky searches
etc. on the content of resources using fields (lets say dublin
core elements). But this would be quite a different thing to
querying on WebDAV properties.

Hence I was interested to understand better the goal of DASL.
Is it to be able to query WebDAV properities (and nothing else).
Or was it intended to be broader and cover the harder problem
of querying content as well?

Just curious to understand the intended scope better before
I jump in. I found a reference to a dasl requirements document
(I have not looked it up yet). But is it still valid? I ask
only because if its been a while and if no one has implemented
it, is it because they have been busy, or because DASL has
missed the mark in some way?

Alan

ps: I noticed that DASL seems to allow other queries to be
plugged in. While this is good, for the above I am not after
an answer like "you can do anything you like". I am more
interested in "what do people like/want?"

pps: I also noticed that the "basic" query langauge looked
rather long when you got down to it - orderby, contains, like,
three value logic... Convienient if you have an SQL engine around
I guess.

Hello Alan,

You mentioned it, DASL define a mini query language to query property mostly
and "server-defined" query languages, that can do want they want (the only
thing those languages need is clients supporting those languages).

I have the feeling, that also the mini query language should be extendable
to define additional content operators. A query covering both content and
properties is required to my understanding (again the question of available
clients).

An extendable mini query language would reduce the need to define an own
"server-defined" query language and you get both content and property query
in a more "standard" way.

Best regards,

juergen pill

Hello,

I am trying to create a text file on a URL in a Java class.

The directory requires username and password to access.

How/where can I set these in the code?

	url = new URL("http://myserver/webdav/myFile.txt");
            connection = (HttpURLConnection)aUrl.openConnection();
            connection.setRequestMethod("PUT");
            connection.setDoOutput(true);
            out = new PrintWriter(connection.getOutputStream());
        	out.println("Some Text");
            out.close();

Currently I get a 401 authorization error.

Thanks,
Rob.

In the past, we produced both a Scenarios and a Requirements specification.
I believe that both are still largely valid.  The only significant new
factor that has emerged since these documents were initially drafted is the
XML Query effort.

The scenarios and requirements documents can be found at:

That's what I would think as well... Both properties and content searchability
would be good.

My company just upgraded my web servers from Windows NT to Windows 2000 with
IIS 5.0. I was using the Posting Acceptor to upload documents to my intranet
site.  All the documentation that I have read so far has said not to use the
Posting Acceptor for Windows 2000 but to use this WebDAV.  My question is
really simple.  HOW???   I need to have the ability to have users go to my
site and upload documents to the site. Is this something that WebDAV can do?
I have no idea where to begin with this. Help Please.

   From: Peter Raymond [mailto:Peter.Raymond@merant.com]

   In my earlier e-mail I mentioned that I was unsure about the
   contents of the DAV:bindings property.  Here is some more detail
   about why I think it is unclear, also find attached some PowerPoint
   slides which I used to try to understand the bindings property.

   I guess there are two things in the text that mislead me: 

   1) Section 13.1 says that the property "contains a complete list of
      all bindings to that resource", but also says it is necessary to
      select one URI mapping for a collection.  It seems to contradict
      itself, it is not complete because it only contains one URI
      mapping for a collection.

A binding is an named association between a collection and a resource,
where the "name" is a URI segement.  You perhaps are confusing a
"binding" with a "mapping" (where a "mapping" is an association
between a URL and a resource).

   2) It also says you should preferably use the mapping in the
      request-URI of the BIND request.  But I am unclear as to which
      BIND request.

The BIND request that created the binding named "bar" from C1 to R2.

      It is a PROPFIND request which was issued to find
      the DAV:bindings property, not a BIND request.

Yes, but that is not relevant for naming all the bindings
(since the collections containing the bindings are in general
unrelated to the request-URL of the PROPFIND request).

      Perhaps it means
      the last BIND request for that collection or perhaps it means
      the first bind request for the resource in the collection?

No, the BIND request that created the binding that is being identified.

   So using the example in Figure 1 of the bindings document you have the
URI 
   paths: 
   /coll1/bar 
   /coll2/bar 
   /coll3/foo 
   /coll1/ and /coll2/ are the same collection resource but all these
   URIs point to the same resource (R2).

OK.

   Imagine you make a PROPFIND request on /coll2/bar, asking for the
DAV:bindings 
   property...should you get: 
   <bindings> 
   <href>/coll1/</href> 
   <segment>bar</segment> 
   <href>/coll2/</href> 
   <segment>bar</segment> 
   <href>/coll3/</href> 
   <segment>foo</segment> 
   </bindings> 

   That is a "complete" list of all bindings for resource R2...

/coll1/bar and /coll2/bar both identify the same binding (from C1 to R2),
so you shouldn't have both in the dav:bindings list.

   BUT section 13.1 says you should pick only one URI for a given
   collection, so perhaps it should return:

   <bindings> 
   <href>/coll2/</href> 
   <segment>bar</segment> 
   <href>/coll3/</href> 
   <segment>foo</segment> 
   </bindings> 

   Because /coll1/ and /coll2/ are the same collection I have picked
   just one URI mapping for that collection...

Yes.

   in this case I used the URI mapping from the PROPFIND request. 

The URI mapping from the PROPFIND request is not relevant.
What is relevant is whether the binding was created by
  BIND /coll3/foo
  Destination: http://host.com/coll1/bar
or 
  BIND /coll3/foo
  Destination: http://host.com/coll2/bar

In the first case, http://host.com/coll1/bar should be in the
DAV:bindings property for R2, while in the second case,
http://host.com/coll2/bar should be in the DAV:bindings
property for R2.

Cheers,
Geoff

   From: Peter Raymond [mailto:Peter.Raymond@merant.com]

   1) Section 9 says that methods MUST produce the same results when
      submitted on different bindings to the same resource.  I
      disagree, if you issue a PROPFIND request on /coll1/bar the href
      returned would be /coll1/bar, if you issue the same PROPFIND
      request on /coll2/bar (which is bound to the same resource) the
      href returned would be /coll2/bar.  The responses would not be
      the same.  I am sure there could be other examples of this.

Yeah, trying to define the semantics of a "binding" is tricky.
I'd have to look up in our notes whether we came up with something
better, or just didn't try.  We might just need to give a method
by method definition of the semantics, and then let folks infer
from that how they should act for future extensions.

   2) We found the definition of the DAV:bindings property in section
      13.1 very confusing.  It would be good to show an example of
      this property, an interesting example would be the DAV:bindings
      on resource R2 from Figure 1.  I will send a separate e-mail on
      this issue.

OK.

   3) Section 15 describes capability discovery and shows the use of a
      header called Public.  I cannot find a definition of this header
      in RFC2518 or RFC2616 (there is a Cache-Control public directive
      but no Public header).  In what specification is this header
      defined?  Maybe I just missed it.

This is a deprecated header from an earlier version of the HTTP-1.1
draft (rfc 2068).  The reference should be removed.

   4) Also on the subject of section 15, it seems we have many ways of
      finding out what capabilities a server or a resource has...Allow
      header, Public header, DAV header, DAV:supported-method-set
      property (in DeltaV).  I find this confusing, and I know in the
      various WebDAV groups there has been some discussion of these
      and the differences between them, I think they should be defined
      clearly and consistently in all the WebDAV related
      specifications.

The Public header is gone, but the rest remain.  We have defined 
DAV:supported-method-set to be the same as Allow, so it really
is DAV header, combined with the DAV:supported-xxx properties.
And we hope to add these properties to the next 2518 draft, so
that they are generally available, and not just in DeltaV.

   5) Section 18 there is a missing space in the last sentence (after
      the 507 code).

Yup.

   6) Is there anyone looking at how bindings affect the other
      protocols, for example have we looked at how DeltaV features
      (like Baseline etc) are affected by bindings?

I tried to keep bindings in mind for all of the of the DeltaV
features.  If you notice anything that might be a problem, please let
me know.

   BTW...are there any server vendors out there that implement or are
   thinking of implementing the BIND method?

Yes.

  Similarly are any clients using it? 

Not yet, as far as I know.

Cheers,
Geoff

Not sure if anybody ever answered your basic question about whether DASL
addresses content querying.  It does.

Here is the query fragment that would search the body of a document:
<D:where>
  <D:contains>Peter Forsberg</D:contains>
</D:where>

This is similar to the property queries, but it does not name a property,
therefore it's the content that must be searched for the string.

Note that it's possible to do exact string matching ("Peter Forsberg") and
string-by-string matching ("Peter" and "Forsberg", not necessarily
together).  Section 5.13.1 of DASL shows both examples.

Lisa,

which version are you referring to? According to [1],

- "contains" is an optional operator (so cou can't rely on it being
supported)
- the method of matching is only loosely defined; in particular you can't
rely on it doing "exact" matching.

I was looking at the same draft.  But I think Alan wanted to know if DASL
addressed body content searching at all, which it does.  If the server
supports it, the client can use it (as usual).

This may be a bit of a can of worms, but is there any interest in using
the structure of content in queries? For example, being able to query
on the content's "Title" or "Author". I am thinking of Dublin Core
metadata sort of approach - not XPath or XML Query since the content
can be anything (PDF, GIF, etc). Allowing something like Dublin Core
would allow a level of structure to be imposed.

If this was considered useful, would the better approach be to define
additional live properites that were automatically extracted from the
content (hence its really just querying on properties after all, not
content itself), or to allow querying on properties or content.
I guess I am sort of asking should <allprops> return the Dublin Core
like elements too? (It could be expensive to compute).

I do a fair bit of work with a search and retrieval protocol, Z39.50.
It is based on the Dublin Core idea of separating your access points
for searching from the physical representation of the data. It allows
querying on "Title" as an abstract concept, without requiring that
it be possible to return a "Title" out from the data. It takes a
different view on query capabilities too - it says you have terms
that can have constraints applied. Specifying a property name to
search within is a constraint. Specifying > (greater than) is a 
constraint. It does not use 3 value logic. It more says 'return
all records that contain some data that match the condition'.
WebDAV might not have the same problem of repeating values as
properites have only one value.

Personally I would like to search on parts of the content using
Dublin Core (or other) metadata standards. Should I do this using
WebDAV properties bound to parts of the content of the resource?
Any other ideas?

Thanks
Alan

ps: I am not likely to do this any time soon. Just thinking about
the future.
