This document uses the terms Experiment and Sample. But in your openBIS application these terms might have been replaced by other words (e.g. Collection instead of Experiment and Object instead of Sample). Please, ask your openBIS administrator for the replacements.

 

Data Set

Represents one set of actual observations, measurements, or analysis results that are made with respect to a specific Sample or in a specific Experiment. One Data Set can contain any number and type of files, e.g. images, csv files or xml files. A Data Set, once registered, cannot be changed anymore (the Data Set is expected to be immutable).

Data Sets that are obtained from a measurement device are called Raw Data Sets, whereas Data Sets obtained from an analysis procedure are called Derived Data Sets.

Data Sets can have multiple children and parents.


Experiment Type

Represents the type of experiments that can be carried out by researchers. For example, siRNA High Content Screening, Mass spectrometry etc.


Experiment

Represents a set of procedures carried out under controlled conditions in order to increase one's understanding of some mechanism, discover an unknown effect or law, to test or establish a hypothesis, or to illustrate a known law.

Experiments can be part of Projects and can logically group an unlimited number of Samples. No child/parent relationships can be attributed to Experiments.


Experiment Property

Represents a description of an experimental property.


File Format Type

Represents the type of file formats that can be used when storing data in a file. For example, for images it could be TIFF. For the storage of N-dimensional data matrices, the file format type could be HDF.


Material Type

Represents the different types of physical substances out of which a thing is or can be made. For example, a virus, gene, oligo nucleotide, cell line or a cell culture, a cell nucleus, a protein, peptide and so on.


Material

Represents a particular physical substance, for example Gene A1BG or the molecule water, i.e. H20 etc.


Person

Represents individuals who interact with the openBIS system. Examples are: Registerer of an Experiment or Registerer of Data.


Sample Type

Represents the type of objects that are produced and measured in the context of an Experiment.
For example, in the case of an RNAi Screening experiment, Sample Types could be: Master Plate, Dilution Plate, Cell Plate, Control Plate


Sample

Represents the actual objects that are measured in the context of an Experiment.

Samples can have unlimited numbers of parents/children. A parent could be, for example, the sample which was used to create a given sample.
In the case, of an RNAi Screening experiment, this could be useful, to keep track of which cell plates where generated from which dilution plates and which dilution plates where generated from which master plates.

There is the possibility to group several samples in a Container Sample (e.g. in NGS a "flow cell" is a container sample for the samples "flow lanes")
