<kwd>

Keyword

A keyword is a finding aid used to record one subject term, key phrase, abbreviation, indexing word, taxonomic structure, or other expression that is associated with the whole structure (such as an book or book part). Keywords can be used for identification, searching, and indexing purposes. A keyword element (<kwd>) may contain a repetition of words found in the structure or it may contain broader terms, narrower terms, related terms, or taxonomic identifiers used to find the structure in a search or provide semantic classification of the text by mapping a specific structure to a taxonomy.

Remarks

Key words are contained in <kwd-group>s. There may be several <kwd-group>s, each of which can be identified separately by language, vocabulary, or taxonomy source. None of the individual keyword elements (<kwd>, <compound-kwd>, <nested-kwd>) take the @xml:lang attribute; that is reserved for the <kwd-group>. This means that keywords must be sorted by language and entered in language groups.

This Tag Set contains several differently-structured types of keywords:

Best Practice: In this Tag Set, nested keywords ( <nested-kwd>) should be reserved for hierarchical material such as taxonomies. There are a few existing tag sets in which keyword nesting is used to simulate a two-part list. In the BITS, such a keyword list should be tagged as a <def-list> instead.

<abstract><p>We describe a method for cloning nucleic acid molecules
onto the surfaces of 5-&#x03BC;m microbeads rather than in biological
hosts. A unique tag sequence is attached to each molecule, and the
tagged library is amplified. Unique tagging of the molecules is
achieved by sampling a small fraction (1%) of a very large repertoire
of tag sequences. ...</p>
