TEI Lex-0 is both a technical specification and a set of community-based recommendations for encoding machine-readable dictionaries. It is rooted in the Guidelines of the Text Encoding Initiative (TEI) and delivered as a customization of the TEI schema.
Following the spirit of TEI Analytics, developed in the context of the MONK project (Zillig 2009), TEI Lex-0 aims at establishing a baseline encoding and a target format to facilitate the interoperability of heterogeneously encoded lexical resources. This is important both in the context of building lexical infrastructures as such (Ermolaev and Tasovac 2012) and in the context of developing generic TEI-aware tools such as dictionary viewers and profilers.
