This message is posted at Feb. 13th 2002, but there is not listed on
Xml linking comment list. I will post again.
We (Fujitsu) are pleased to introduce updated XLiP which newly
supports XPointer and XML base functions. Following is our new
revised implementation report.
Newly supported feature is:
- Almost all XPointer features
- XML Base
All these feature can be tested with our demo application.

XML Linking Implementation Questionnaire
--------------------------------------------------------------------------------
General
What is the name of your organization?
Fujitsu Limited.
How should we contact you on linking matters?
E-mail to mg@jp.fujitsu.com or xlp@ml.fujitsu.co.jp
What is the name of the linking technology?
XLiP (XML Linking Processor)
Please describe its functionality and development status briefly. Is it publicly available?
XLiP is the processor works on DOM. It needs more improvement.
It is easy to append the XLiP to a system using DOM.
XLiP recognizes all XLink features and keeps those information.
By talking to the XLiP, system can handle Liking information in various way.
To show XLiP functionality, tree browser has been implemented as the
demo application. This browser shows document as "tree" based on DOM.
It can traverse from staring resource which is the XML information
set to several types of ending resource (ex. XML information set,
RTF, HTML, TEXT, Image).
This tree browser uses some API of XLiP but supports most of XLink
specification features.
If so, what is its current location?
Publicly available. Only the demo application are available.
In the future, Pocessor itself will be published and publish the API.

XLink
How does the technology use XLink?
In the tree browser application, it uses XLink specification to achieve
hyperjump among nodes and several kinds of resources.
XLink is used to define links and traversal action.
Does (or will) the technology claim XLink conformance?
nothing specal.
Please provide details about the parts of XLink implemented.
-Traversing simple outbound links
In the demo app, starting resource will be shown as the different icon
image. Traversal starts depending upon the "actuate" attribute value.
If "onRequest", traversal starts when user clicks that starting resource
and ending resource directly will be shown according to "show" attribute
value.
But "onLoad" traversal does not supported. simply ignores it.
-Traversing extended outbound links
In the demo app, starting resource will be shown as the different icon
image. Traversal starts depending upon the "actuate" attribute value.
If "onRequest", traversal starts when user clicks that starting resource.
At that time dialog will be shown to specify which ending resouce to traverse.
if the user selects one of the ending resources, it will be shown according to
"show" attribute value.
But "onLoad" traversal does not supported. simply ignores it.
-Traversing extended inbound/third-party links
Same as traversing extended outbound links
In the demo app, starting resource will be shown as the different icon
image. Traversal starts depending upon the "actuate" attribute value.
If "onRequest", traversal starts when user clicks that starting resource.
At that time dialog will be shown to specify which ending resouce to traverse.
if the user selects one of the ending resources, it will be shown according to
"show" attribute value.
But "onLoad" traversal does not supported. simply ignores it.
-show="new"
In the demo app, new window will be created and view the document
including those ending resources. Then set the focus to the ending
resource.
-show="replace"
In the demo app, document including ending resource will be
opened and closed currently viewed document which includes starting
resource. Then set the focus to the ending resource.
-show="embed"
In the demo app, ending resource is embedded as the child of
staring resource.
-actuate="onLoad"
Traversal starts when XLink Processor resolve the XLink declarations and
those starting resources.
-actuate="onRequest"
Traversal starts when user clicks the appropriate cell of the
starting resources.
-XML Base support for relative URIs
supported.
-Linkbase role
supported.
Linkbase can be loaded along with the value of "actuate" attribute. When running
the demo application, those timings are as follows:
onRequest ... user clicks that starting resource.
onLoad ... processor loads that starting resource.
Any other comments/details?
What difficulties did you discover in using the XLink specification?
What difficulties did you discover in implementing XLink?
XPointer
How does the technology use XPointer?
Does (or will) the technology claim XPointer conformance?
No.
Please provide details about the parts of XLink implemented.

Bare names
Supported.
Currently, the processor recoginzes attribute which has "id" for its name
as ID attribute.
Child sequences
Supported.
id() function
Supported.
But same condition with Bare names
Full XPath
range-to
Supported.
string-range
Supported.
But it is difficult to show the result.
Namespace support
Supported.
In programming API
Yes.
In user interface
Yes.
XLinkTreeViewDemo application provides the function
to address the nodes which identified by the user
specified XPointer string through a input dialog.
Selecting/showing multiple non-contiguous ranges
Yes.
Any other comments/details?
What difficulties did you discover in using the XPointer specification?
Syntax makes xpointer string too long.
What difficulties did you discover in implementing XPointer?
It doesn't simply implemented on top current XPath
implementation. Location set concept requires essential
improvement of XPath implementation.
XML Base
How does the technology use XML Base?
Does (or will) the technology claim XML Base conformance?
No.
Please provide details about the parts of XML Base implemented.
In the XLiP, XML Base is used to resolve the relative URI in
"href" attributes of XLink namespace.
What difficulties did you discover in using the XML Base specification?
None.
What difficulties did you discover in implementing XML Base?
Distinction between URL and system identifier.
Integration
How does the technology uses XLink, XPointer, and XML Base in conjunction?
XLink resolution is processed at first. In that process, XPointer
resolving processing and XML Base resolving processing be called.
Please provide details about the implementation.
Handling single nodes as participating resources
Handling ranges of nodes as participating resources
Handling participating resources made up of non-contiguous pieces
Any other comments/details?
What difficulties did you discover in using their specifications together?
It doesn't have any difficulties. Easy to use.
What difficulties did you discover in implementing them together?
It will not so difficult to implement together.
Conclusion
Do you have any other comments you would like to share with us?
