API data model

Here is described an overview of the data models for RSpace ELN and Inventory APIs.

Inventory is currently in 'alpha' release and not yet generally available - please see Inventory Hub for details.

1. RSpace ELN Data model

The RSpace ELN API data model contains all the elements present in the UI, but in a simpler form. The diagram shows the relations between the elements.

Folders and Notebooks are containers for Documents. Gallery Folders contain Files. A document contains one or more Fields that contain the document's content and links to attached Files.

The type and number of Fields is defined by a Form definition. A Form contains FormFields that define a Field.

Documents, Notebooks, Folders, Forms and Files all have owners, that are Users (relation omitted for clarity on the diagram). Users can belong to one or more Groups; and their role within the group is stored in UserGroup objects.

2. RSpace Inventory Data model

The core data objects are Sample, Subsample and Container. A Sample is a description of a reagent, chemical or resource. A SubSample represents a physical item - e.g. a tube, vial or bottle - containing some Sample. A Container represents a storage unit such as freezer, box or shelf.

All the core data objects can have arbitrary metadata associated with them using ExtraFields.

Samples and Containers have an owner who is a User.

Notes can be appended to Subsamples, recording observations or events.

Different type of Container exist : List, Grid and Visual containers. Containers can contain nested containers (to any depth), or subsamples. The location of items in a Container is represented by ContainerLocation.

Samples can have a defined list of SampleFields. The definition of a Sample is stored by a SampleTemplate. A SampleTemplate can represent a 'type' of Sample such as antibody, restriction enzyme, microscope slide etc.

The diagram below shows the key relations. Not all properties are shown - please consult the API documentation for full details.
