The <code>corpus.update</code> method ensures, that the original
<code><a href="/link/WebCorpus?package=tm.plugin.webmining&version=1.1" rd-options="" data-mini-rdoc="tm.plugin.webmining::WebCorpus">WebCorpus</a></code> feed sources are downloaded and
checked against already included <code>TextDocument</code>s.
Based on the <code>ID</code> included in the
<code>TextDocument</code>'s meta data, only new feed elements are
downloaded and added to the <code><a href="/link/WebCorpus?package=tm.plugin.webmining&version=1.1" rd-options="" data-mini-rdoc="tm.plugin.webmining::WebCorpus">WebCorpus</a></code>. All
relevant information regariding the original source feeds
are stored in the <code><a href="/link/WebCorpus?package=tm.plugin.webmining&version=1.1" rd-options="" data-mini-rdoc="tm.plugin.webmining::WebCorpus">WebCorpus</a></code>' meta data
(<code><a href="/link/CMetaData?package=tm.plugin.webmining&version=1.1&to=tm" rd-options="tm" data-mini-rdoc="tm::CMetaData">CMetaData</a></code>).

tm.plugin.webmining facilitates text retrieval from feed
    formats like XML (RSS, ATOM) and JSON. Also direct retrieval from
    HTML is supported. As most (news) feeds only incorporate small
    fractions of the original text tm.plugin.webmining even retrieves
    and extracts the text of the original text source.
