Dataset Cita)on & Iden)fiers Data Cita)on Iden)fiers 101 Dataset Iden)fica)on with EZID Choosing an Iden)fier Looking ahead By Brain farts (Joschua) hLp://www.flickr.com/photos/brainfarts/97676505/

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 Adapted from ESIP

What this means…

Iden)ﬁers 101

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) By Joelk75: hLp://www.ﬂickr.com/photos/75001512@N00/2728233597/

Iden)ﬁer example string: doi:10.9999/FK40K2GTV html version: hLp://dx.doi.org/10.9999/FK40K2GTV loca)on: hLp://www.bologna.edu/biology/xfg/123.xls metadata creator: Dr. Felix KoLor :tle: Data for chromosomal study of cagish (Ictalurus punctatus) publisher: University of Bologna date: 8/31/2011

Iden)ﬁer example string: doi:10.9999/FK40K2GTV html version: hLp://dx.doi.org/10.9999/FK40K2GTV loca)on: hLp://www.state.edu/ecology/783sdr/123.xls metadata creator: Dr. Felix KoLor :tle: Data for chromosomal study of cagish (Ictalurus punctatus) publisher: Dryad Data Repository date: 10/01/2011

Create & manage persistent identifiers and associated metadata •  Allows precise identification of a dataset •  Allows credit for data producers and data publishers •  Provides a link from the traditional literature to the data •  Potential for research metrics for datasets Example: Sidlauskas, B. 2007. Data from: Tes)ng for unequal rates of morphological diversifica)on in the absence of a detailed phylogeny: a case study from characiform fishes.

DOIs and ARKs Both: •  Work like regular hyperlinks •  Refer to a subset or por)on of a resource •  Become persistent when the target URL is maintained hLp://content.cdlib.org/ark:/13030/g0v19n605/, courtesy of UC Davis Special Collec)ons

DOIs vs ARKs •  Case sensi)ve •  Special feature supports granularity •  Less costly

DOIs vs ARKs suﬃx pass-‐through string: ark:/99999/Big4/* loca)on: hLp://x.y.z/foo/Big4/db/*

DOIs vs ARKs suﬃx pass-‐through string: ark:/99999/Big4 /table/cell/45-‐8.txt loca)on: hLp://x.y.z/foo/Big4/db /table/cell/45-‐8.txt

DOIs vs ARKs •  Established brand in publishing •  Indexed by major A&I cita)on databases •  Cannot be deleted •  More costly
