ESCO-occupations

Definition

Please consult the ESCO definition.

Description

Occupations in ESCO are structured according to ISCO (International Standard Classification of Occupations), the international standard for classifying occupations. Occupation-name concepts in the Swedish Public Employment Service's classification are structured according to SSYK (Swedish standard for occupational classification), which is based on ISCO.

ESCO-occupations in the Taxonomy

The Taxonomy represents all ESCO occupations as their own concepts. Mappings to the Taxonomy occupations are represented as mapping relations according to SKOS. URIs to the ESCO concepts are found through the esco-uri attribute.

The example below shows what such a concept might look like in the Taxonomy. Note that there is an additional attribute to represent URIs (uri). This attribute can be used by external sources to reference concepts within the Taxonomy.

{
    "id": "v2kx_tST_Zy2",
    "preferred_label": "kemist",
    "type": "esco-occupation",
    "esco_uri": "http://data.europa.eu/esco/occupation/0d93706d-32fd-4de3-aa08-be1003e325da",
    "uri": "http://data.jobtechdev.se/taxonomy/concept/v2kx_tST_Zy2"
}

Mappings

The different types of mapping relations can be found in the relations chapter. An ESCO occupation can be mapped towards one or more Taxonomy occupation-name concepts, and vice versa.

The example below shows the ESCO occupation kemist and some of its mappings to occupation-name concepts.

graph TD;
    A(kemist) -->|narrow-match| B(Materialkemist)
    A(kemist) -->|narrow-match| C(Organisk kemist)
    A -->|exact-match| D(Kemist)

Managing the mappings

The mapping has been carried out, and is managed, by an editorial team within Arbetsförmedlingen.

Due to the fact that all occupation-name concepts need to be mapped to one or more ESCO occupations, new mappings are constantly being added as new occupation-name concepts emerge or become deprecated. Therefore, it is to be expected that each new Taxonomy version will involve some changes in regards to the mappings to some, usually a lesser, extent.

The mappings are determined through manual analysis and with adherance to the ESCO's instructions.

ESCO versions

With each release of a new ESCO version, the upcoming Taxonomy version is updated with any changes to the ESCO skills.

Presently, however, ESCO versions are not explicitly represented in the Taxonomy.

The mapping subsytem can however be used to target specific ESCO versions.
