Structured data format (sdata)

Design goals

  • open data format for open science projects
  • self describing data
  • flexible data structure layout
    • hierarchical data structure (nesting groups, dictionaries)
    • (posix path syntax support?)
  • extendable data structure
    • data format versions
  • platform independent
  • simple object model
  • support of standard metadata formats (key/value, ...)
  • support of standard dataset formats (hdf5, netcdf, csv, ...)
  • support of standard dataset types (datacubes, tables, series, ...)
  • support of physical units (conversion of units)
  • transparent, optional data compression (zlib, blosc, ...)
  • support of (de-)serialization of every dataset type (group, data, metadata)
  • easy defineable (project) standards, e.g. for a uniaxial tension test (UT)
  • (optional data encryption (gpg, ...))
  • change management support?
  • Enable use of data structures from existing tensor libraries transparently
  • (single writer/ multiple reader (swmr) support)
  • (nested data support)
df = pandas.DataFrame({"a":[1,2,3]})
import sdata
data = sdata.Data(name="my_data", table=df, comment="A remarkable comment")
data.metadata.add("my_key", 123, unit="m^3", description="a volume")
data.metadata.add("force", 1.234, unit="kN", description="x force")
data.to_xlsx(filepath="my_data.xlsx")
print(data.metadata.df)
          name                             value  dtype unit description
key                                                                     
name      name                           my_data    str    -            
uuid      uuid  08222ca66e5047808bdc3b35d8f17224    str    -            
my_key  my_key                               123    int  m^3    a volume
force    force                             1.234  float   kN     x force
