Hierarchical Structure of Metadata

Metabolonote manages metadata for experimental data sets based on the hierarchical structure shown below. This structure is based on the Togo Metabolome Data Format (TogoMD) we defined.

 SE (Sample Set information)
  |- S (Sample information)
  |  |- M (Method of Instrumental Analysis information)
  |     |- D (Data Analysis information)
  |       (|- P (Peak information）*Not used in the Metabolonote)
  |- SS (Detailed information of Sample Preaparation)
  |- MS (Detailed information of Method of Instrumental Analysis)
  |- DS (Detailed information of Data Analysis)
  |- AM (Detailed information of Metabolite Annotation)

One sample set (SE) could include multiple samples (S), one sample could be analyzed by multiple instruments and their settings (M), and one analytical data could be processed by multiple computational tools (D) to generate peak data (P).

ID Label	Classification	Description
SE	Sample Set information	Information about a set of experimental data corresponding to the study purpose, including information regarding data interpretation and handling, such as which sample should be compared with which control, etc.
S	Sample information	Information about sample preparation methods.
M	Method of Instrumental Analysis information	Information about methods of instrumental analysis.
D	Data Analysis information	Information about data analysis methods by using computational tools, etc.
P	Peak information	Information about metabolite peaks obtained by data analysis. (This class is not used in Metabolonote, defined for databases that store peak information)
SS	Detailed information regarding sample preparation Analysis details information	Detailed information regarding sample preparations commonly applied to several samples, including information about growth conditions, drug treatments, etc. Referred to by S (Sample information).
MS	Detailed information regarding Method of Instrumental Analysis	Detailed information regarding analysis methods commonly applied to several analysis experiments, including information about what kind of devices were used under what kind of settings, etc. Referred to by M (Method of Instrumental Analysis information).
DS	Detailed information regarding Data Analysis	Detailed information regarding data analysis methods commonly applied to several data analysis cases, including information about what kind of software programs were used with what kind of parameters, etc. Referred to by D (Data analysis information).
AM	Annotation Method information	Information about method of metabolite peak annotation Referred to by P (Peak information).
