RDF從零開始

Question

所以我試圖將XML文件轉換爲RDF，但不知道如何去做。

這裏我開始從頭開始做我自己的RDF：

<?xml version="1.0" encoding="UTF-8"?> 

    <rdf:RDF 
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 
    xmlns:db="http://drugbank.ca#"> 

    <rdf:Description rdf:about="http://drugbank.ca/DB00001"> 
     <db:name>Lepirudin</db:name> 
     <db:description:>Lepirudin is identical to natural hirudin except for substitution of leucine for isoleucine at the N-terminal end of the molecule and the absence of a sulfate group on the tyrosine at position 63. It is produced via yeast cells.</db:description> 
     <db:substrate></db:substrate> 
     <db:enzymes></db:enzymes> 
     <db:mechanism-of-action>Lepirudin forms a stable non-covalent complex with alpha-thrombin, thereby abolishing its ability to cleave fibrinogen and initiate the clotting cascade. The inhibition of thrombin prevents the blood clotting cascade.</db:mechanism-of-action>

我已經開始抵消權（第一次也是最後一次）......任何提示將幫助很多。謝謝

Answer 1

我會建議的第一件事是你使用W3C validator。這樣做，你會發現你的RDF有一些錯誤。這些行是錯誤的：

<db:description:>Lepirudin .. 
<rdf:Description rdf:about="http://drugbank.ca/DB00002> 
<db:description:></db:description> 

其次，我建議使用突出RDF語法的文本編輯器（emacs運作良好）。這樣，你會很容易地看到你的語法錯誤。
