A RICH Set of USER-Friendly Features 

Data Citation:

Credit as an incentive to Share Data

  • A formal data citation automatically generated
  • Attribution to data creators and data providers 
  • Persistent identifier (e.g., DOI) resolves to dataset landing page
  • Version in citation
  • Universal Numerical Fingerprint (UNF):  a checksum independent of file format, for tabular data files
  • Compliant with the Joint Declaration of Data Citation Principles

Download data citation ready to be used in reference manager

Metadata TO FIND AND REUSE DATA

At multiple Levels:

  • Citation metadata
  • Custom metadata
  • File metadata
  • Variable-level metadata 

With multiple Standards:

  • Data Documentation Initiative (DDI)
  • Dublin Core
  • Schema.org 

Download metadata in multiple formats

Schema.org  USed BY GOOGLE DAtaset SearcH

  • Schema.org JSON-ld embedded in HTML of dataset landing page
  • Datasets become discoverable through Google Dataset Search

Metadata from schema.org in Dataverse dataset landing page

Versioning OF DATASETS AND FILES 

  • Major and minor versions
  • Major versions show in the data citation
  • Track both metadata changes and files changes

 

TIERED ACCESS to Data

  • Default access is public, with CC0 waiver
  • Allow public and restricted files
  • Descriptive metadata always public for discoverability
  • Custom Terms of Use, when needed 
  • Optional Guestbook to collect information from users

Public

Restricted

Tabular data exploration

  • Variable metadata automatically extracted
  • Descriptive statistics automatically computed

Metadata Extraction from Astronomy files

Metadata (instrument information) is extracted automatically from FITS files header upon data upload

Metadata from FITS Header

MANAGE and customize your own Dataverse

  • Create a dataverse to manage your own collection of datasets
  • Brand your dataverse or embed in your website
