Data Stewardship for SPATIAL/IsoCamp 2014

  1. 1. Data Stewardship Carly Strasser California Digital Library carlystrasser@gmail.com SPATIAL / IsoCamp June 2014 Tips & Tools
  2. 2. FromFlickrvialibrarianinsta.tumblr.com I am not a librarian. But I do work at a library.
  3. 3. Enable data sharing Encourage new incentives Think about code sharing Work with libraries, publishers and researchers Explore new tools to help change system Build tools
  4. 4. Why are you here? Science: you’re (probably) doing it wrong
  5. 5. Back in the day… Da Vinci Curie Newton classicalschool.blogspot.com Darwin
  6. 6. Research has changed Better
  7. 7. From wikimedia Such Internet! So many tools! From Flickr by John Jobby So much data!
  8. 8. Research has changed Worse
  9. 9. Digital data FromFlickrbyFlickmor FromFlickrbyUSArmyEnvironmentalCommand FromFlickrbyDW0825 C. Strasser CourteseyofWHOI FromFlickrbydeltaMike
  10. 10. Digital data + Complex workflows
  11. 11. Scientists are bad at data management.
  12. 12. An embarrassing example… From Flickr by lincolnblues
  13. 13. ?
  14. 14. From Flickr by ransomtech Didn’t share the data Didn’t document the data (metadata) Didn’t document provenance/workflow
  15. 15. From Flickr by ransomtech Reproducibility Transparency Reuse NO
  16. 16. From Flickr by johntrainor Why should I care?
  17. 17. Because reproducibility* is one of the fundamental tenets of science. *reproducibility: being able to go from data to figures/results not reproducibility: independently verifiable via following same techniques.
  18. 18. Because reproducibility is one of the fundamental tenets of science. Because we need to be credible.
  19. 19. Because reproducibility is one of the fundamental tenets of science. Because we need to be credible. Because Fox News, creationism, and the war on science.
  20. 20. “Help us identify grants that are wasteful or that you don’t think are a good use of taxpayer dollars.” ! Rep. Adrian Smith (R-Nebraska), a member of the House Committee on Science and Technology
  21. 21. Because reproducibility is one of the fundamental tenets of science. Because we need to be credible. Because Fox News, creationism, and the war on science Because it means faster progress.
  22. 22. Because you are a good person.

  31. 31. data management FromFlickrbyBigSwedeGuy Best Practices
  32. 32. From Flickr by Mark Sardella Plan before data collection
  33. 33. •  Create a key (data dictionary) •  Make sure names are unique •  Define codes FromFlickrbyzebbie Planning Design sample naming scheme
  34. 34. PhDcomics.com Planning Design file naming scheme
  35. 35. Use descriptive file names •  Unique •  Reflect contents From  R  Cook,  ESA  Best  Practices  Workshop  2010   Bad: Mydata.xls 2001_data.csv best version.txt Better: Eaffinis_nanaimo_2010_counts.xls Site name Year What was measured Study organism *Not for everyone * Planning Design file naming scheme
  36. 36. Biodiversity Lake Experiments Field work Grassland Biodiv_H20_heatExp_2005to2008.csv Biodiv_H20_predatorExp_2001to2003.csv … Biodiv_H20_PlanktonCount_2001toActive.csv Biodiv_H20_ChlAprofiles_2003.csv … From S. Hampton Planning Design file organization Consider… •  Dependencies? •  File formats? •  Time of collection? •  Order of analysis?
  37. 37. Planning Constrain entries Atomize Break down spreadsheets Design your spreadsheet
  38. 38. A relational database is A set of tables Relationships among the tables A language to specify & query the tables A RDB provides Scalability: millions+ records Features for sub-setting, querying, sorting Reduced redundancy & entry errors From Mark Schildhauer Planning Consider a database
  39. 39. You should invest time in learning databases if your data sets are large or complex Consider investing time in learning databases if your data are small and humble you ever intend to share your data you are < 30 years old Planning From Mark Schildhauer Consider a database
  40. 40. Store your data in a repository Institutional archive Discipline/specialty archive Pick a data repository From Flickr by torkildr Ask a librarian Repos of repos: databib.org re3data.org Planning
  41. 41. FromFlickrbysepasynod From Flickr by taberandrew From Flickr by withassociates What software? What hardware? What personnel? How often? Set up reminders! Test system Decide on preservation/backup Planning
  42. 42. …document that describes what you will do with your data throughout the research project From Flickr by Barbies Land Write a data management plan! Planning
  43. 43. DMP components But they all have different requirements and express them in different ways •  What will be collected •  Methods •  Standards •  Metadata •  Sharing/access •  Long-term storage Planning From Flickr by Barbies Land

  45. 45. During Data Collection & Entry From Flickr by Julia Manzerova
  46. 46. Realistically: •  Archive .csv version of raw data •  Make a “raw” tab in working data file •  Do all work on other tabs During collection Keep raw data raw
  47. 47. Raw data as .csv R script for processing & analysis During collection Ideally: •  Use scripts to process data •  Save them with data Keep raw data raw
  48. 48. During collection Document your workflow Temperature data Salinity data Data import into Excel Analysis: mean, SD Graph production Quality control & data cleaning “Clean” T & S data Summary statistics Data in spread- sheet Workflow: how you get from the raw data to the final products of your research Simple workflow: flow chart
  49. 49. During collection Workflow: how you get from the raw data to the final products of your research Simple workflow: commented script •  R, SAS, MATLAB… •  Well-documented code is Easier to review Easier to share Easier to use for repeat analysis # % $ & Document your workflow
