Building linked lexicography applications with LexO-server.

The article focuses on LexO-server, a backend system providing RESTful services for managing lexical resources modeled with OntoLex-Lemon, a W3C standard for representing lexical data linked to ontologies. LexO-server supports various lexicographic tasks—including editing, linking, visualization, and linguistic annotation—by offering modular services for both lexical and conceptual data, the latter represented using the Simple Knowledge Organization System (SKOS). The system facilitates interoperability and reuse of linguistic linked data by enabling integration with external ontologies and services such as Keycloak for user management and Zotero for bibliographic references. Demonstrated through three web applications, LexO-server aims to support diverse research and digital humanities needs, with future developments planned to enhance support for multiple linguistic category catalogs, OWL ontologies, metadata standards, and interoperability with non-linked data models like TEI and TBX.
