This paper describes the LiLa Knowledge Base of interoperable linguistic resources for Latin. Resources are made interact by representing their (meta)data through common ontologies, vocabularies, and data categories, in accordance with the principles of the Linked Data paradigm. After presenting the overall architecture of LiLa, which is based on a collection of canonical citation forms of Latin words, the paper details the ontological modeling of each of the lexical and textual resources currently interlinked in the Knowledge Base. Finally, a few perspectives for the near future are sketched.
