推荐答案

它与我们现在所知的网络有何不同?

How will it be different to the web we know now?

现在的 HTML+CSS 更侧重于结构和表现.语义是关于信息的意义.在语义网中，您使用共享的本体来建立对象的意义(语义)和意义对象之间的关系.最著名的本体是:FOAF 和 都柏林核心.

Right now the HTML+CSS is centered more on structure and presentation. Semantics is about the meaning of the information. In semantic web you use shared ontologies to establish meaning (semantic) of the object and meaning of relations between the objects. Best known ontologies are: FOAF and Dublin Core.

通常语义会用专门的语言表达，例如 RDF 或 OWL.RDF 可以使用 eRDF 或 W3C 的 RDFa.

Typically semantics would be expressed in specialized language, such as RDF or OWL. RDF can be embedded within XHTML using eRDF or W3C's RDFa.

结构化程度较低的 eRDF/RDFa 替代方案是微格式.

Less structured alternative to eRDF/RDFa are microformats.
