alLidd
alLidd is a modular, open-source framework designed to store, interlink, and query multilingual lexical data and related knowledge. It supports cross-language information retrieval, lexicography, and language-technology development by providing a shared data model and contributor tooling. The data model is graph-based: concepts, terms, languages, senses, and relations form nodes and edges; each language term can attach definitions, examples, and part-of-speech information, and translations map to related concepts across languages. Provenance and licensing are integral for governance and attribution.
Architecture and operation are centered on a graph store, a reasoning layer for lightweight inferences, and
History and development trace the project to a collaboration among linguists, computer scientists, and open-data advocates
Applications and impact include use in digital lexicography, language-learning platforms, NLP research pipelines, and multilingual search
