Invitation to comment on Data Model for Lexicography v1.0

Second public review ends February 29th

OASIS and the OASIS Lexicographic Infrastructure Data Model and API (LEXIDMA) TC are pleased to announce that Data Model for Lexicography Version 1.0 is now available for public review and comment. This 30-day review is the second public review for this specification.

About the specification draft:

The LEXIDMA TC’s high level purpose is to create an open standards based framework for internationally interoperable lexicographic work. Data Model for Lexicography v1.0 describes and defines standard serialization independent interchange objects based predominantly on state of the art in the lexicographic industry. The TC aims to develop the lexicographic infrastructure as part of a broader ecosystem of standards employed in Natural Language Processing (NLP), language services, and Semantic Web.

This document defines the first version of a data model in support of these technical goals, including:
– A serialization-independent Data Model for Lexicography (DMLex)
– An XML serialization of DMLex
– A JSON serialization of DMLex
– A relational database serialization of DMLex
– An RDF serialization of DMLex
– An informative NVH serialization of DMLex
