Agenda

• Review some past activities• Plan some future activities

Activities since start of SC workshop• Vocab.lternet.edu server now allows Metacat

searches– AND implementation searches using either keyword

set• Suggested revisions to list organization (Don,

Julia)– Many have been made

• Discussion of how Core areas should be incorporated– Margaret has an email detailing how core areas should be used – but

outside the controlled vocabulary– Separate vocabulary/taxonomy for research themes – may also be

used for other things (pubs)• With Core Area as high level entity• In a separate keyword thesaurus

– Sites?• Site is supposed to be listed as organization in the EML, according to “best

practices”….– But many sites don’t comply

• Also from package ID• Lots of ways to do this…..• Organization vocabulary or hierarchy

Core Research Area Taxonomy• LTER Core Research Areas– Primary Production– Populations– Disturbance– Inorganic Nutrients– Organic Matter

• Keywords from this taxonomy would go into a SEPARATE <keywordSet> with a different keywordThesaurus from the science keywords – See:
