The OntoLex W3C Community Group published its final report on the Lexicon Model for Ontologies (lemon) in May 2016, specifying a suite of vocab-ularies for the linguistic grounding of ontologies and RDF datasets in general. The Linguistic Metadata (LIME) vocabulary is the lemon module describing coarse-grained metadata about datasets as a whole, to represent resuming infor-mation at the level of ontology-lexicon interface. The purpose of this metadata is to support the understanding and exploitation of available lexical material, and in the first place to facilitate the discovery of datasets that may be of interest. To-wards the realization of that vision, we propose an API that supports the manip-ulation of LIME metadata, as well as its automatic generation by means of a pro-filer. We discuss the architecture of the API, as well as the main design decisions, which can inform the development of APIs for other vocabularies
