INDIGO Graffiti Thesaurus


street art


The INDIGO Graffiti Thesaurus is a curated academic resource centred on contemporary graffiti terminology, with a spatial focus on the Danube Canal in Vienna, Austria. It is not just a compilation of terms, but also a specialised tool that organises and categorises graffiti-related concepts within a controlled vocabulary. More specifically, it takes the form of a thesaurus, where concepts are connected to each other through equivalence, hierarchical, and associative relationships.

By leveraging the Simple Knowledge Organization System (SKOS) data model, the thesaurus ensures consistency and precision in its representation of information. The use of SKOS not only makes the thesaurus accessible but also interoperable, allowing for seamless integration with other widely used resources such as Wikidata and the Getty Art & Architecture Thesaurus (AAT) of the J. Paul Getty Trust and Getty Research Institute. The thesaurus is inspired by the AAT and therefore also contains information provided under the ODC Attribution License by the Getty Research Institute. Moreover, the content systematically reflects the structure of the AAT by using facets, hierarchy names, and guide terms.

The thesaurus is made available through the Vocabs service of the Austrian Centre for Digital Humanities and Cultural Heritage (ACDH-CH), which utilises Skosmos, an open-source software tailored for publishing vocabularies. For enhanced accessibility, the thesaurus can be queried via a REST API (Representational State Transfer Application Programming Interface), facilitating its interaction with data over the World Wide Web. Moreover, its availability in diverse data formats, including TSV (Tab-Separated Values) and JSON (JavaScript Object Notation), caters to a wide range of academic and technological preferences.

With its unique focus on the graffiti culture of the Danube Canal, the thesaurus offers a deep insight into Vienna's Danube Canal contemporary graffiti world and serves as a valuable tool for all those interested in this form of creativity.
