遇到的一些问题，望高人指点一二：
1.用PROTEGE +OWLS EDITOR建立了一个Web服务描述，用文本查看工具打开建立的OWL文件，为什么PROTEGE创建的文档格式与往上下载的一些服务描述文件格式相差很远呢？网上下载的一些服务描述格式工整，可读性强，但PROTEGE创建的OWL文件，可读性就很差了。这是为什么呢？难道PROTEGE就不能创建出格式清晰的文档吗？
2.用PROTEGE +OWLS EDITOR建立了一个Web服务描述，里面包含的关于swrl的命名空间以及本体导入，如：
xmlns:swrlb="http://www.w3.org/2003/11/swrlb#"
在用OWLS API（MARYLAND）解析的时候，会出错，这又是什么原因呢？
3.用OWLS API（MARYLAND）解析OWL文档时，需要从网络上读取Profile本体，因为在头文件里导入了：
<owl:imports rdf:resource="http://www.daml.org/services/owl-s/1.1/Profile.owl" />
如果没有网络连接，OWLS API是不是就不能解析了呢？
单独用PROGETE 打开一个OWLS文件也有这个问题
4.下面附上一个从网络上得到的服务描述，这个描述要比PROTEGE简洁很多
