10 keywordSet and keyword

This element is found at these locations (XPath):

It is recommended that meaningful sets of keywords each be contained within <keywordSet> tag. Use one <keywordSet> for a group of terms identifying the contributing organization(s), e.g., the LTER or OBFS site, LTREB or Macrosystems project , which is especially if data are co-funded or funding is leveraged. Meaningful geographic place names also are appropriate (e.g. state, city, county). If groups of keywords are from a specific vocabulary, its name belongs the optional tag <keywordThesaurus>.

Context: Communities sometimes have specific requests for keywords to assist in searches. E.g, the LTER requests that keywords should include a LTER core research area(s), the network acronym (LTER, ILTER, etc.), three-letter site acronym and site name. In addition to specific keywords, relevant conceptual keywords should also be included, e.g., from the LTER Controlled Vocabulary.
