New position

since 1st of september i've joined the LIFL as a post-doc for one year.
for the time being, everything is fine. i've already participated to a first ITEA CAM4HOME project meeting in Luxembourg. CAM4HOME is the main project i'll be working on at LIFL . our participation, mainly concerns the modelling and the management of metadata about content (elements) and aggregation of content (bundles).

i'll also participate to vision-related project developped within my new team : Fox-Miire. i'm enthusiastic about discovering this new research domain.

that's all for the time being

cheers chers readers

Web Services...

For a long time i want to get more familiar with WebServices and this morning i could not sleep (waiting some results and being very anxious about) and i discovered the Axis Tutorial. Wow it's pretty amazing how WS is simple with Axis...
I'm looking forward to get to work and to try some things out...

What's a bit curious is that there still much command line examples. that's ok 'cause i'm a command line lover but still .... i'm curious if there are some IDE plugins (NetBeans or Eclipse) that's automatise the process.

Do not hesitate to make some suggestion for a WS newbie ;)

cheers,

graphical models

Currently, I'm working on graphical models for machine learning.

It's a very interesting topic which reminds me of my bachelor courses and the law of probabilities. For the time being, i can manage formulas computation ... but i lack of intuition for what all those results represents!

Hopefully in a couple of days i'll get over this intuition problem!

XQuery extension under Saxonica

An extension function is invoked using a name such as prefix:localname(). The prefix is associated with a namespace declaration that is in scope.

The namespace URI is used to identify a Java class, and the local name is used to identify a method.

Examples:
xmlns:date=”java:java.util.Date” or xmlns:date=”http://www.jclark.com/xt/java/java.util.Date”

While using the Saxon implementation : http://saxon.sf.net/ points to the class net.sf.saxon.functions.Extensions except for saxon:evaluate

The command line option -TJ debugs the loading of Java extensions: detailed information about the possible matchings.

The call binding is always made at the time the XPath expression is compiled. If similar name, distance parameters.

Calling Static Methods in a Java Class date:static_method()
* Static methods can be called directly. hyphen notation toString becomes to-string in XQuery
* A static Java method called as an extension function may have an extra first argument of class net.sf.saxon.expr.XPathContext

Calling Constructors date:new()
* Java constructors are called by using the function named new()
* The only things that can be done with a wrapped Java Object are to assign it to a variable, to pass it to an extension function, and to convert it to a string, number, or boolean

Calling Java Instance-Level Methods date:to-string(date:new()) or date:to-string($e)
* Instance-level methods are called by supplying an extra first argument of type Java Object which is the object on which the method is to be invoked

CLASSPATH should contain the folder where Java Classes are stored!
