The LiLa project consists in the creation of a Knowledge Base of linguistic resources for Latin based on the Linked Data framework and aimed at reaching interoperability between them. To this goal, LiLa integrates all types of annotation applied to a particular word/text into a common representation where all linguistic information conveyed by a specific linguistic resource becomes accessible. The recent inclusion in the Knowledge Base of information on word formation raised a number of theoretical and practical issues concerning its treatment and representation. This paper discusses such issues, presents how they were addressed in the project and describes a number of use-case scenarios that employ the information on word formation made available in the LiLa Knowledge Base.
