LIME (LInguistic MEtadata) is a vocabulary for expressing linguistic metadata about linguistic resources and linguistically grounded datasets.
The metadata vocabulary has been initially presented at the LDL conference and then contributed as the metadata module of the OntoLex suite of Ontology-Lexicon vocabularies. The last publication about it has been presented at ESWC2015
