hi friends.,
 I am Ashoksundar.
 could somebody help me in getting the user manual for WOP (Web Of
Patterns).

-- 
kind regards,
Ashoksundar.U

Hi Graig,

Could you send me some details that would help us to reconstruct the
project: 

-          if possible, zip the project (including .classpath) and send it
to my

-          - which JDK/ Eclipse/ WOP version are you using?

Cheers, Jens

Subject: [Webofpatterns-user] Problem scanning a project

Hello,

    I get the following exception when scanning a Java project with web of
patterns:

    An unexpected exception occured while trying to generate the workspace:
dir should be a directory; C:\Workspace2\org.eclipse.ant.tests.core\bin is
not.

    The program can not progress beyond this point.

                                                      Sincerely,

                                                      Craig

Dear all,

We have just released a new version of the web of patterns client. It
contains two major new features:

1. built-in support for visualisation. 

There is a new extension point that allows to plugin visualisation modules.
These modules can "draw" patterns and/or pattern instances. There are two
such plugins wop has on-board: one uses the RDF visualisation as used by the
W3C, one is based on the DPML language developed by the University of
Auckland. 

2. built-in support for exporting pattern definitions and instances

There is a new extension point for export, and an implementation that
exports patterns into instances of an open schema
(http://www-ist.massey.ac.nz/wop/20070227/patterninstancereport.xsd) . 
Stylesheets (XSL and CSS) are also generated (so the reports can be viewed
in a web browser), and the generated report contain a generated figure for
each pattern instance found if the DPML plugin is available. 

WARNING: Massey University is currently replacing some web servers. Some
services wop uses may temporary become unavailable. This includes: the main
pattern repository (but the wop client has a cached version on board), the
wopper discovery/publishing/feedback web service and the abovementioned
schema. It is still possible to use the scanner, to export instances and to
discover/publish using delicious, swoogle and other services.

Thanks to Nathan Jones and Graham Jenson for their contributions to this
version!!

Kind regards, Jens

Dear all,

We have some trouble with our network here - the pattern URLs on the Massey
server are not accessible at the moment (404s). We will try to sort this out
asap. For now, please use the patterns in the local cache.

Dear all,

Graham Jenson has just joined the wop development team. In the next few
months he will work on pattern visualisation. In particular, we want to
integrate the visualisation of patterns and pattern instances using DPML and
UML2.0 into our tool. Another part of his project is adding an open
import/export API to interact with other tools.

Cheers, Jens

Hi Jens,

You may take a look at the ContractLog KR
(http://ibis.in.tum.de/staff/paschke/rbsla/index.htm) and the OWL2PROVA
framework. Maybe it is interesting for you and I'm happy about any =
comments.

ContractLog implements a hybrid DL-typed unification, which allows using
rules in combination with description logics. The hybrid approach has =
the
advantage that efficient tableaux reasoning algorithms of external DL
reasoners can be used. This is different from the homogenous approach of
SWRL which uses the rule engine for DL reasoning. See
http://ibis.in.tum.de/staff/paschke/docs/ContractLog_OWL_12_05.pdf for =
more
information.

The OWL2PRova API implements both approaches: hybrid and homogeneous
integration and supports different reasoners (RDFS, OWL Lite, OWL DL =
etc.)
and converters for transforming DL ontologies into logic programs, e.g.
homogenous description logic programs.

Cheers,

Adrian

Betreff: [Webofpatterns-user] new version released

Dear all,

We have just release version 1.2.0 with the following new features:=20

We have added a new reasoning module that uses SWRL to make rules
persistent. Rules can be built for all contributed properties.=20
Swoogle now contributes several properties, and publishing patterns to =

has been added.

Note that the online properties (delicious bookmark count, meta data
provided by swoogle, wopper stats) are now fetched in the background.
Sometimes this fails (in particular delicious returns a 503 from time to
time indicating that it does not like so many RPC calls). In this case,
default values are used. See also the log view for details.=20

Dear all,

I have just released version 1.1.0 of the WebOfPatterns client for Eclipse.
This version contains several new collaborative features based on semantic
web technology: patterns can be discovered using search engines and
bookmarking services, patterns can be registered with those services, and
patterns can be rated using rules and explicit and harvested meta data.
Extensions can provide additional properties that can later be used to
reason about patterns. 

These new features are provided through extensions (for the respective
Eclipse extension points defined in our plugin), with existing
implementations based on (the APIs of) blogger, del.icio.us, swoogle (a
semantic web search engine) and a new tailored wop server ("wopper").
Therefore, the wop client now consists of multiple plugins. 

Now we need your help. If you have time, please download the software and
try out some of the collaborative features. E.g., try to discover patterns,
rate existing patterns or extract your own patterns from a Java project and
publish them. Your feedback is highly appreciated! If you discover bugs,
please post those on source forge and we will try to iron them out asap. 

The software can be downloaded from here:
http://sourceforge.net/project/showfiles.php?group_id=104645

Platform: Java 1.5, Eclipse 3.1 or 3.2. 

Kind regards, Jens

Hi,

I have just added a new committer to the project. Nathan Jones will work on
a SWRL based reasoning module used to select "good" patterns.

There are a number of new projects in the (SVN) repository. In a nutshell, I
have restructured the plugin so that it contains a couple of extension
points. The idea is that certain services (pattern discovery, pattern
publishing, feedback, reasoning to select patterns) are delegated to other
plugins. This includes the following (existing) plugins: 

- publishing / discovery based on delicious bookmarks [RC - release
candidate] 
- publishing / discovery based on blogger blogs [RC]
- publishing / discovery based on wopper - this is a db based webapp running
on our server at Massey [beta]
- a simple reasoning service [RC]
- a more advanced reasoning service based on SWRL [skeleton] (this is
Nathan's part) 

See http://www-ist.massey.ac.nz/wop/docs/plugin/wopplugins.png for an UML
diagram explaining the structure. 

I have finally managed to add and test Proxy support to the main plugin. I
hope to be able to publish version 1.1 including all these features (except
the SWRL reasoning) within 2 weeks.

Dear all,

I have just migrated WOP from CVS to subversion. The main reason was that
the SF CVS services was fairly unstable in recent weeks, and I had to move
the repository to an internal server.  

The repository can be found here:

Subversion Server: 	https://svn.sourceforge.net
Path to Repository: 	/svnroot/webofpatterns

Modules created are: 

reflect - the reflection framework used by wop
wop - the kernel
wop-eclipse-plugin - the eclipse plugin
wop-eclipse-plugin-dispub-blogger - extension providing publish and discover
functions based on the blogger API (NEW !!)
wop-eclipse-plugin-dispub-delicious - extension providing publish and
discover functions based on the blogger API (NEW !!)

The last two modules extend the new extension point wop_discover_and_publish
in the eclipse plugin. They are still under construction, if would
appreciate any help testing them, particularly if you are behind a proxy
that requires authentication !!! In general, the blogger plugin is almost
finished, but I still have connectivity problems with the delicious API. 

/Jens

Hi,

I have just tried to reproduce this and get different results. Here is =
what I did:

- created a new Java project
- set the compiler compliance level to 5.0
- added a src folder
- set the src folder as source folder
- added the javax/swing folder from the src included in the JDK =
distribution to src
- had a surprise that this worked (I expected it would fail due to some =
special rules to load java and javax packages)
- started to scanner and found 10 instances of Composite

Please check the console for outputs and post error messages if there =
are any. Also check whether the compliance level is 5.0 (by default, it =
is 1.4 !!).=20

Regarding identity constraints: if switched on, only =
=E2=80=9Cnormal=E2=80=9D instances are selected. Please see our SWESE =
paper for a formal definition of normal and an example of a =E2=80=9Cnot =
normal instances=E2=80=9D.=20

Kind regards, Jens

PS: the exported Composite instances found in Swing (Swing only, AWT not =
included - ignore the "-" signs, I have copied the code from Firefox ):

Apologies for cross postings !!

We (= the software engineering group at Massey University NZ) have just
released version 1.0 of our WebOfPatterns Eclipse plugin. The plugin can be
used to access online pattern repositories, to browse repositories, and to
scan Java projects for instances of the patterns defined in these
repositories. Instances can be aggregated and exported to XML. The plugin
has a local repository on board that can be used when the plugin is in
offline mode. The local repository contains the definitions of the following
GangOf4 patterns: Adapter, AbstractFactory, Bridge, Composite, Proxy,
Singleton, and TemplateMethod. The plugin also features a wizard that can be
used to extract and publish patterns found in projects. The idea is to
provide a tool for software engineers to share their knowledge about design,
i.e. to publish knowledge as well as to consume it. 

The plugin requires Eclipse 3.1 or better and Java 5.0. For more details,
see http://www-ist.massey.ac.nz/wop/ or the eclipse help pages contributed
by the plugin. There are some new screenshots on the project page.

Project Page: http://www-ist.massey.ac.nz/wop/ 
Download Page: http://sourceforge.net/project/showfiles.php?group_id=104645 
Installation: copy jar file into Eclipse plugins folder and restart Eclipse

Future Plans (later this year)

   1. An improved scan engine (in particular an improved AST analyzer).
   2. Integrating behavioural analysis based on AOP (integration of an
existing BE project).
   3. Publishing/ searching using Swoogle, del.icio.us, GoogleBase ..
   4. SWRL based reasoning to select "good" patterns (ongoing BSc Hon
project).

Special thanks to Chris Elgar and Jevon Wright for their contributions!!

Dear all,

We have just tagged the wop-eclipse-plugin project as version. This version
is the result of a student summer project at Massey University done by Jevon
Wright and supervised by Jens Dietrich. In a nutshell, it is now possible to
select a java project in the Eclipse Java perspective and find the instances
for patterns defined in RDF in this project. The WOP workspace is built
dynamically from the eclipse project settings. A visual pattern browser has
also been integrated into Eclipse.  The third function is new - the ability
to extract patterns from eclipse java projects. This works as follows: a
wizard is used to select classes, their properties and relationships. These
artefacts can then be renamed using abstract role names, meta data (Dublin
Core) can be attached and the respective RDF file is generated. We also
generate RSS files to be used with Google Base, although this feature is
still experimental. We will continue to explore the use of services such as
Google Base and del.icio.us to attach meta info to pattern definitions and
repositories, and the use of derivation rules to process this information.
This is to support pattern discovery and selection. There will be two more
student projects on these issues in 2006 at Massey supervised by Jens.

There are two main limitations in the current prototype: 
1. There is currently only one pattern in the default repository
(AbstractFactory). This is because we have refactored the ontology in order
to align it with the work done by Tichelaar et al ("A Meta-model for
Language-Independent Refactoring1"), and we still have to refactor the other
patterns (i.e., the patterns supported by earlier versions of wop -
http://sourceforge.net/project/showfiles.php?group_id=104645 ). We expect
this to be done until the end of March. Since the default repository is
deployed on our web server, fixing this problem will not require a client
update. 

2. The validation function in the publishing wizard is not yet working. The
idea is to run the wop scanner and make sure that it finds the pattern
instance that has been used to extract the pattern. This will also be fixed
until the end of March. 

The current version can be accessed as follows: 

-	please use Eclipse 3.1 and JDK 5 
-	go to the CVS Repository Exploring Perspective and create a new
repository location using the following settings: server
cvs.sourceforge.net, Repository Path /cvsroot/webofpatterns, use your source
forge id or anonymous as user name, and pserver as protocol
-	Open the repository location created, navigate to
Versions/wop-eclipse-plugin/VERSION_1_0_PREVIEW
-	Check out

Once you have downloaded the project, switch to the resource perspective,
open plugin.xml and click on "Launch an eclipse application " in the plugin
editor panel. This will open a new eclipse window. To run the scanner, you
will need a (non-trivial) java project. You can easily pull two sample
projects from source forge (into the eclipse instance started by the
plugin): HEAD/reflect-examples-mysqlconnectorj from /cvsroot/webofpatterns
or VERSIONS/mandarax/v_3_4 from /cvsroot/mandarax. Another interesting
project is HEAD/wop-examplesfrombooks with examples from two books on design
patterns which we have used to validate our pattern definitions. 
Important: if you connect to the internet through a proxy, you must
configure it in Eclipse (Windows->Preferences->WOP Preferences).

If you want to stay informed about wop and the upcoming release of version
1.0, please consider joining our mailing list
(http://sourceforge.net/mail/?group_id=104645). Any feedback is welcome !
Please use SF bug tracking to post issues.

Hi,

I have just installed Prot=E9g=E9 3.1 beta and discovered that it can =
now
deal with owl:import statements. This means that you can now load the
entire WOP pattern catalogue into Prot=E9g=E9.=20
Here is how to do it:=20
=20
- Download Prot=E9g=E9 3.1 beta from http://prot=E9g=E9.stanford.edu=20
- Download the full version with plugins (the actual download page is
http://protege.stanford.edu/download/prerelease/full/), and install the
OWL plugins=20
- Start Prot=E9g=E9
- Create a new project, use project type "OWL Files (.owl or .rdf)"
- Check "create from existing sources"
- Click next and copy the following into the "File name or URL" field:
 http://www-ist.massey.ac.nz/wop/20050204/wop-catalogue.rdf
- That's it - you can now do things like creating a java api or creating
an OWLDoc documentation. Unfortunately, the DC meta data are not
visible.=20

Cheers, Jens

- PS: I am not sure how Prot=E9g=E9 makes it through the proxy, perhaps =
it
uses the MSIE settings. It just worked.

Hi,

I have just released version 0.4 of the WOP client. 

This version adds support for aggregated pattern instances, and some
minor changes in the reporting engine. 

If a scan is cancelled, the report will now be built and displayed for
all patterns that have already been scanned. This version has still
certain performance problems we hope to be able to address in the
upcoming 1.0 version. It is recommended to use JDK 1.5. Although the
software runs under 1.4.2 the application seems to freeze sometimes when
scanning.

Cheers, Jens

Hi all,

We have just released a new version of the wop tool. It contains a
temporary fix for the Xalan-JDK1.5 issue (see also
http://issues.apache.org/jira/browse/XALANJ-1978) that was causing
trouble in our reporting engine; and new system property viewer in the
client to make it easier to detect the JDK version and other config
info. The tool should now run fine under JDK 1.5 !

We have also added a new (CVS-) module BEHAVE and welcome Jevon Wright
as a new developer. Jevon will start working on BEHAVE, adding
facilities to perform behavioural analysis of java programs. This will
result in gathering records representing relationships between program
artefacts which are not accessible using reflection, AST analysis or
analysis of naming patterns. 

Cheers, Jens

Hi,

The first version of the new pattern browser tool is now available. It
is in the CVS (swing-ui module, the executable class is PatternBrowser),
and will be part of the next wop release. In a nutshell, the tool
connects to a WOP server, downloads the patterns and builds a graph
visualizing the respective pattern. 

The graph displays one pattern participant together with the
participants it depends on and its dependents. The edges are labelled
with the constraint name. The participants can be double-clicked in
order to navigate through the pattern. 

I think this tools will be very useful to document and understand
patterns. In a future version we will add support for generating images
we could put on the web site (e.g. using Batik or a JPG encoder).

Dear all,

I am sending this email to everybody who is interested in our web of
pattern project. In a nutshell, WOP is a formal representation of
software design using semantic web technology and a tool that scans java
software for design pattern instances based on this representation. 

Summary

1 New WOP Mailing List
2 New versions of the ontology and the wop tool suite released
3 Roadmap
4 Publications

1 WOP Mailing List created

In the future, all wop project related news will be broadcasted using
the new WOP users mailing list. So, if you are interested, please join
the source forge mailing list. The URL is
 <https://lists.sourceforge.net/lists/listinfo/webofpatterns-user>
https://lists.sourceforge.net/lists/listinfo/webofpatterns-user.

2 New versions of the ontology and the wop tool suite released

We have released new versions of the ontology, the pattern scanner and
the standalone wop application. The links have been updated on the web
page. Here are the most important changes:

*	An extended vocabulary. In particular, support for associations
has been added.
*	Directed constraints.
*	An improved constraint scheduler based on the JGraphT library.
*	Now 7 patterns are supported.
*	Improved reporting using XML/XSL.
*	Client logs memory, and starts with customized initial memory.
*	New platform independent distribution (there were problems with
the installers built for Unix).
*	The standalone application contains examples based on the
"Patterns In Java" book, Mandarax, AWT/Swing and JDBC/MySQL ConnectorJ.
*	Pattern instance aggregators (in wop, not yet supported by the
user interface/reporting tool).

The software can be accessed from the source forge download page or
directly from the cvs server. See the download section on the project
web page for details. For direct access to the ontology resources, click
on the links on the web page. 

For the practising software engineers among you - please download the
client and give it a go!

3 Roadmap

Until 10 February

*	Support for more patterns
*	Support for pattern refinement.
*	Support for pattern instance aggregation.

Until the end of 2005

We will have 2-3 more people working on the project, and hope to add the
following features: 

*	Dynamic code analysis.
*	Full integration into Eclipse (as plug-in).
*	Looking into how to generalize some of the results to include
anti-patterns and refactoring.
*	Adding patterns for AOP / an AOP ontology ("A" means aspect, not
agent here!). 

4 Publications

Chris and myself have written a paper on WOP that got accepted for the
Australian Software Engineering Conference (ASWEC2005). 

Kind regards, Jens
