The event will consist of a number of brief status update presentations followed by open discussions. The goal is to get a good picture of the current state of the W3C Community Groups Ontology-Lexica (OntoLex), Linked Data for Language Technology (LD4LT) and Best Practices for Multilingual Linked Open Data (BP-MLOD), and to agree on future directions for the OntoLex vocabulary, community standards for linguistic annotations and language resources on the web and the development and documentation of best practices related with these. In addition, the workshop will serve as a meeting place for these communities and a place to discuss future directions for both our standards and the research community behind. The workshop will discuss the on-going development of community standards for language resources as linked data. We will review the current progress of the Ontolex group in linguistic morphology (OntoLex-Morph), corpus-based information in lexical resources and linguistic annotations on the web (OntoLex-FrAC, LD4LT), recent developments in the development of language resource and lexical metadata (LD4LT) as well as proposed initiatives for terminological and multimedia/multimodal resources and the development of best practices (BPMLOD). We will specifically discuss future directions and topics that the participating W3C Community Groups will focus on in the next years.
