Question

所以我试图将XML文件转换为RDF，但不明白如何。

在这里，我开始从头开始创建自己的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>

    </rdf:RDF>

我是否开始正确（第一次和最后一次）......任何提示都会有所帮助。感谢

我建议的第一件事是你使用W3C validator。这样做，您将看到RDF中存在一些错误。这些行是错误的：

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

其次，我建议使用突出显示RDF语法的文本编辑器（emacs运行良好）。这样，您将很容易看到语法错误的位置。

RDF从头开始
