XML Schema for the Semantic Crawling Sitemap Extention. Last Modified 2/8/2007 The main idea is to describe equivalences and alternative ways for a Semantic Robot (client or crawler) to access Semantic Web data offered by a host. One such equivalence is declared by the <cs:dataset> tag, which is used at the same level as <url> tags in the sitemap. It is RECOMMENDED to set a label describing the dataset. It is RECOMMENDED to set a URI for the dataset. This facilitates the provision of further future annotations. It is suggested this URI to be a URL on the same domain pointing to a RDF description to of the dataset A prefix for linked data that a server hosts. URI/URLs that begin with this prefix will resolve to their RDF description. The location of a fragment of an RDF data dump, used for large datasets which are "split" over several files. It is RECOMMENDED to set a label describing the dataset.
