Various issues and trade-offs emerging from the conversion are discussed. The conversion implementation employed the STELETO transformation tool.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>The ILC conversion captures some of the ILC facet structure by a limited extension beyond the SKOS standard. SPARQL examples illustrate how this extension could be used to create faceted, compound descriptors when indexing or cataloguing. Basic query patterns are provided that might underpin search systems. Possible routes for reducing complexity are discussed.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>Complex classification schemes, such as the ILC, have features which are not straight forward to represent in SKOS and which extend beyond the functionality of the SKOS standard. The ILC's facet indicators are modelled as <jats:italic>rdf:Property<\/jats:italic> sub-hierarchies that accompany the SKOS RDF statements. The ILC's top-level fundamental facet relationships are modelled by extensions of the associative relationship \u2013 specialised sub-properties of <jats:italic>skos:related<\/jats:italic>. An approach for representing faceted compound descriptions in ILC and other faceted classification schemes is proposed.<\/jats:p><\/jats:sec>","DOI":"10.1108\/jd-10-2020-0167","type":"journal-article","created":{"date-parts":[[2021,2,13]],"date-time":"2021-02-13T10:33:00Z","timestamp":1613212380000},"page":"926-945","source":"Crossref","is-referenced-by-count":3,"title":["Migrating a complex classification scheme to the semantic web: expressing the Integrative Levels Classification using SKOS RDF"],"prefix":"10.1108","volume":"77","author":[{"given":"Ceri","family":"Binding","sequence":"first","affiliation":[]},{"given":"Claudio","family":"Gnoli","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5222-0430","authenticated-orcid":false,"given":"Douglas","family":"Tudhope","sequence":"additional","affiliation":[]}],"member":"140","published-online":{"date-parts":[[2021,3,26]]},"reference":[{"key":"key2022041311120597300_ref001","unstructured":"Austin, D.
