    XML is at the core of the emergence of a semantic web.
    There is a nice explanation on Semaview web site:

    "What is an ontology?<br>An ontology defines the terms used to describe and represent concepts. Ontologies are used to describe concepts as well as their inter-relationships. Being able to standardize the definition of real-world concepts becomes very powerful as you begin to investigate knowledge that spans across multiple domains."

    Designed as a one minute overview of the Semantic Web, this illustration discusses a half dozen key points in language that can be understood by managers and techies alike.

    Semaview "At-a-Glance" Illustration Series: RDF and XML
    XML and RDF are two complimentary technologies being used to build an internet that is more intelligent. As a developer, you must decide which combinations of standards to use for your application. While XML is more widely adopted, and has many more tools and examples to reference, the addition of RDF gives your computer more knowledge about what your data actually means. This illustration discusses approximately a dozen key points in language that can be understood by managers and techies alike.

    The problem with XML is that it is really verbose: we now have 5000 lines of variables and program :mad: and it is not finished yet but the functionality is more my priority that optimising the coding part at the moment.

    I will also get a headache to transfer some excel formulas into XML like this one :D. Hmm there is some characters that don't pass in the post so the formula is truncated.

    IF((MAX($D20:I20)<J20)*((DVAR(INDEX(SR2_TRIE,EQUIV(J20,SR2_TRIE,-1)+1),2) = MAX($D20:I20))),";255.0.0;2;LT/d",IF((DVAR(INDEX(SR2_TRIE,EQUIV(J20,SR2_TRIE,-1)+2))= MAX($D20:I20))*(IF(ESTNA(RECHERCHEH(";255.0.0;2;LT/d",$B21:I21,1)),1,RECHERCHEH(";255.0.0;2;LT/d",$B21:I21,1)="")),";255.0.0;2;LT/d",""))&SI((J20>J18)*(J20<I20)*(I20>H20)*(J20>H20)*(J20>MAX($C18:I18)),";255.0.0;2;Feynman LT/d","")&SI((J17=10)*(J20>J18)*(J20<MAX($C20:I20)),";255.0.0;2;Feynman LT/d","")&SI(I20=MIN($D20:$M20)*(MAX(L20:$L20)>MIN($D18:$M18)),";0.255.0;2;Feynman LB/d","")&IF(I20=MAX($D20:$M20),";255.0.0;2;Feynman LT/d","") ...

    One of the most elegant aspects of making money is that it comes down to only one action (hitting the T) as a consequence of considering two truly orthogonal sets.

    Coupling DRY to the strategy just as elegantly follows from only using feedback repitition in non intimate ways. Avoiding intimacy is done by the isolation strategies found in decoupling and least connectedness.

    Corruption through multiple definition is a trivial concern in any elegant approach. Vapid as a possibility.

    If ET goes beyond beginner and novice to hot $hit levels of trading, we will see the true vitality of using orthogonality in a corroborating function.

    Making money is totally based upon change over time. Assimilating periodicity that occurs in independant systems is what boldly introduces orthogonality as a structural strength not attainable unless independant systems are merged in a time bound "process".
