What cita)on offers
• To aid scien)fic reproducibility • To provide fair credit • To ensure scien)fic transparency & accountability
• To aid in tracking the impact, including – helping data authors verify use of their data – helping future data users iden)fy how others have used the data

What is an iden)fier?
What you see: alphanumeric string (never changes) Associated with: loca)on of object (such as a URL) OpDonal: who, what, when, etc (i.e. metadata)

Both: • Work like regular hyperlinks • Refer to a subset or por)on of a resource
• Become persistent when the target URL is maintained
DOIs and ARKs
• Case sensi)ve • Special feature supports granularity • Less costly
DOIs vs ARKs
string: ark:/99999/Big4/*
loca)on: hLp://x.y.z/foo/Big4/db/*
suffix pass-‐through DOIs vs ARKs
string: ark:/99999/Big4
loca)on: hLp://x.y.z/foo/Big4/db
suffix pass-‐through DOIs vs ARKs

/table/cell/45-‐8.txt
• Established brand in publishing • Indexed by major A&I cita)on databases • Cannot be deleted • More costly
DOIs vs ARKs
