Taxonomy CSV Format

The Tabiya CSV format is used to import and export data from the Tabiya Open Taxonomy platform.

Each taxonomy version is made up of nine CSV files Each file contains a different type of data. The files are:

General notes on the fields of the CSV files

UUID History

A UUIDHISTORY field is a list of all the UUIDs that have been assigned to an entity during its lifecycle, e.g. when the entity is created, imported, exported or copied into our platform.

It is an identifier that can be used for tracking objects not only across their lifecycle, but also across systems.

The UUID history is ordered from newest to oldest UUID.

The first entry in the list is the current UUID of the object. The last entry in the list is the very first (initial) UUID of the object.

The entities in this dataset have been assigned an initial UUID. When an entity is imported into our platform, a new UUID will be issued and added at the top of UUID history.

The UUID used by the platform are based on the Universally Unique Identifier v4 standard.

The maximum number of UUIDs in the history for an object is constrained to 10000.

Origin Uri

The ORIGINURI field is a URI that points to the location where an entity was originally defined.

The maximum length for the Origin Uri is 4096 characters.

ID

The ID field is a unique identifier for each entity in the CSV dataset. It is used for referencing within the CSV dataset, for example, in the relations between entities.

This field is not meant to be used as an identifier outside the scope of the CSV files, for that purpose you should use the first entry in the UUID History.

Object Types

The object types are used to differentiate between different types of entities in the dataset.

For example in relations between entities, the object types are used to specify the type of the parent and child objects and determine in which file these objects can be located.

The object types in the CSV files are:

  • skill: Represents a skill.

  • skillgroup: Represents a skill group.

  • escooccupation: Represents an occupation that originates from the ESCO framework.

  • localoccupation: Represents an occupation that not originate from the ESCO framework and is defined only this taxonomy.

  • occupationgroup: Represents an Occupation group.

Lists

List properties are stored in the CSV files as strings separated by a character. Currently, we do not support values that contain a new line.

Dates

The dates in the CSV files are stored in the ISO 8601 format.
